WARNING

1. Electric shock prevention

Make sure the power is shut OFF before connecting a unit and a motor to the power.

Do not open the front cover while the power is ON or during operation. Failure to observe this could lead to electric shocks.

Do not operate the unit with the front cover removed. The high voltage terminals and charged sections will be exposed, and can cause electric shocks.

Do not remove the front cover and connector even when the power is OFF unless carrying out wiring work or periodic inspections. The inside of the units is charged, and can cause electric shocks.

Since the high voltage is supplied to the main circuit connector while the power is ON or during operation, do not touch the main circuit connector with an adjustment screwdriver or the pen tip. Failure to observe this could lead to electric shocks.

Wait at least 15 minutes after turning the power OFF, confirm that the CHARGE lamp has gone out, and check the voltage between P and N terminals with a tester, etc., before starting wiring, maintenance or inspections. Failure to observe this could lead to electric shocks.

Ground the unit and motor. For the motor, ground it via the drive unit.

Wiring, maintenance and inspection work must be done by a qualified technician.

Wire the servo drive unit and servo motor after installation. Failure to observe this could lead to electric shocks.

Do not touch the switches with wet hands. Failure to observe this could lead to electric shocks.

Do not damage, apply forcible stress, place heavy items on the cables or get them caught. Failure to observe this could lead to electric shocks.

Always insulate the power terminal connection section. Failure to observe this could lead to electric shocks.

After assembling the built-in IPM/SPM spindle motor, if the rotor is rotated by hand etc., voltage occurs between the terminals of lead. Take care not to get electric shocks.

WARNING

2. Injury prevention

When handling a motor, perform operations in safe clothing.

In the system where the optical communication with CNC is executed, do not see directly the light generated from CN1A/CN1B connector of drive unit or the end of cable. When the light gets into eye, you may feel something is wrong for eye.

(The light source of optical communication corresponds to class1 defined in JISC6802 or IEC60825-1.)

The linear servo motor, direct-drive motor and built-in IPM/SPM spindle motor uses permanent magnets in the rotor, so observe the following precautions.

(1)Handling

• The linear servo motor, direct-drive motor and built-in IPM/SPM spindle motor could adversely affect medical electronics such as pacemakers, etc., therefore, do not approach the rotor.

• Do not place magnetic materials as iron.

• When a magnetic material as iron is placed, take safety measure not to pinch fingers or hands due to the magnetic attraction force.

• Remove metal items such as watch, piercing jewelry, necklace, etc.

• Do not place portable items that could malfunction or fail due to the influence of the magnetic force.

• When the rotor is not securely fixed to the machine or device, do not leave it unattended but store it in the package properly.

• When installing the motor to the machine, take it out from the package one by one, and then install it.

• It is highly dangerous to lay out the motor or magnetic plates together on the table or pallet, therefore never do so.

(2)Transportation and storage

• Correctly store the rotor in the package to transport and store.

• During transportation and storage, draw people's attention by applying a notice saying "Strong magnet-Handle with care" to the package or storage shelf.

• Do not use a damaged package.

(3)Installation

According to each unit or motor specification

(Note) For details, confirm each unit or motor specifications in addition.

When disinfectants or insecticides must be used to treat wood packaging materials, always use methods other than fumigation (for example, apply heat treatment at the minimum wood core temperature of 56 °C for a minimum duration of 30 minutes (ISPM No. 15 (2009))).

If products such as units are directly fumigated or packed with fumigated wooden materials, halogen substances (including fluorine, chlorine, bromine and iodine) contained in fumes may contribute to the erosion of the capacitors.

When exporting the products, make sure to comply with the laws and regulations of each country.

Do not use the products in conjunction with any components that contain halogenated flame retardants

(bromine, etc). Failure to observe this may cause the erosion of the capacitors.

Securely fix the servo motor to the machine. Insufficient fixing could lead to the servo motor slipping off during operation.

Always install the servo motor with reduction gear in the designated direction. Failure to do so could lead to oil leaks.

Structure the rotary sections of the motor so that it can never be touched during operation. Install a cover, etc., on the shaft.

When installing a coupling to a servo motor shaft end, do not apply an impact by hammering, etc. The encoder could be damaged.

Do not apply a load exceeding the tolerable load onto the servo motor shaft. The shaft could break.

Store the motor in the package box.

When inserting the shaft into the built-in IPM/SPM spindle motor, do not heat the rotor higher than 130°C.

The magnet could be demagnetized, and the specifications characteristics will not be ensured.

Always use a nonmagnetic tool (explosion-proof beryllium copper alloy safety tool: NGK Insulators, etc.) when installing the built-in IPM/SPM spindle motor, direct-drive motor and linear servo motor.

Always provide a mechanical stopper on the end of the linear servo motor's travel path.

If the unit has been stored for a long time, always check the operation before starting actual operation.

Please contact the Service Center, Sales Office or dealer.

Install the heavy peripheral devices to the lower part in the panel and securely fix it not to be moved due to vibration.

CAUTION

(2) Wiring

Correctly and securely perform the wiring. Failure to do so could lead to abnormal operation of the motor.

Do not install a condensing capacitor, surge absorber or radio noise filter on the output side of the drive unit.

Correctly connect the output side of the drive unit (terminals U, V, W). Failure to do so could lead to abnormal operation of the motor.

When using a power regenerative power supply unit, always install an AC reactor for each power supply unit.

In the main circuit power supply side of the unit, always install an appropriate circuit protector or contactor for each unit. Circuit protector or contactor cannot be shared by several units.

Always connect the motor to the drive unit's output terminals (U, V, W).

Do not directly connect a commercial power supply to the servo motor. Failure to observe this could result in a fault.

When using an inductive load such as a relay, always connect a diode as a noise measure parallel to the load.

When using a capacitance load such as a lamp, always connect a protective resistor as a noise measure serial to the load.

Do not reverse the direction of a diode which connect to a DC relay for the control output signals such as contractor and motor brake

Servo drive unit

Control output signal output, etc. to suppress a surge. Connecting it backwards could cause the drive unit to malfunction so that signals are not output, and emergency stop and other safety circuits are inoperable.

Do not connect/disconnect the cables connected between the units while the power is ON.

Securely tighten the cable connector fixing screw or fixing mechanism. An insecure fixing could cause the cable to fall off while the power is ON.

When using a shielded cable instructed in the instruction manual, always ground the cable with a cable clamp, etc. (Refer to "EMC Installation Guidelines")

Always separate the signals wires from the power line.

Use wires and cables that have a wire diameter, heat resistance and flexibility that conforms to the system.

(3) Trial operation and adjustment

Check and adjust each program and parameter before starting operation. Failure to do so could lead to unforeseen operation of the machine.

Do not make remarkable adjustments and changes of parameter as the operation could become unstable.

The usable motor and unit combination is predetermined. Always check the combinations and parameters before starting trial operation.

The direct-drive motor and linear servo motor do not have a stopping device such as magnetic brakes.

Install a stopping device on the machine side.

When using the linear servo motor for an unbalance axis, adjust the unbalance weight to 0 by installing an air cylinder, etc. on the machine side. The unbalance weight disables the initial magnetic pole adjustment.

CAUTION

(4) Usage methods

In abnormal state, install an external emergency stop circuit so that the operation can be stopped and power shut off immediately.

Turn the power OFF immediately if smoke, abnormal noise or odors are generated from the unit or motor.

Do not disassemble or repair this product.

Never make modifications.

When an alarm occurs, the machine will start suddenly if an alarm reset (RST) is carried out while an operation start signal (ST) is being input. Always confirm that the operation signal is OFF before carrying out an alarm reset. Failure to do so could lead to accidents or injuries.

Reduce magnetic damage by installing a noise filter. The electronic devices used near the unit could be affected by magnetic noise. Install a line noise filter, etc., if there is a risk of magnetic noise.

Use the unit, motor and regenerative resistor with the designated combination. Failure to do so could lead to fires or trouble.

The brake (magnetic brake) of the servo motor are for holding, and must not be used for normal braking.

There may be cases when holding is not possible due to the magnetic brake's life, the machine construction (when ball screw and servo motor are coupled via a timing belt, etc.) or the magnetic brake's failure. Install a stop device to ensure safety on the machine side.

After changing the programs/parameters or after maintenance and inspection, always test the operation before starting actual operation.

Do not enter the movable range of the machine during automatic operation. Never place body parts near or touch the spindle during rotation.

Follow the power supply specification conditions given in each specification for the power (input voltage, input frequency, etc.).

Set all bits to "0" if they are indicated as not used or empty in the explanation on the bits.

Do not use the dynamic brakes except during the emergency stop. Continued use of the dynamic brakes could result in brake damage.

If a circuit protector for the main circuit power supply is shared by several units, the circuit protector may not activate when a short-circuit fault occurs in a small capacity unit. This is dangerous, so never share the circuit protector.

Mitsubishi spindle motor is dedicated to machine tools. Do not use for other purposes.

This unit is not intended for use in low voltage public networks that supply power to households. Using this unit in such networks may cause radio frequency interference.

Do not use this unit in residential areas.

(5) Troubleshooting

If a hazardous situation is predicted during power failure or product trouble, use a servo motor with magnetic brakes or install an external brake mechanism.

Always turn the main circuit power of the motor OFF when an alarm occurs.

If an alarm occurs, remove the cause, and secure the safety before resetting the alarm.

CAUTION

(6) Maintenance, inspection and part replacement

Always backup the programs and parameters before starting maintenance or inspections.

The capacity of the electrolytic capacitor will drop over time due to self-discharging, etc. To prevent secondary disasters due to failures, replacing this part every five years when used under a normal environment is recommended. Contact the Service Center, Service Station, Sales Office or dealer for repairs or part replacement.

Never perform a megger test (measure the insulation resistance) of the drive unit. Failure to observe this could lead to faults.

If the battery low warning is issued, immediately replace the battery. Replace the batteries while applying the drive unit's control power.

Do not short circuit, charge, overheat, incinerate or disassemble the battery.

For after-purchase servicing of the built-in motor, only the servicing parts for MITSUBISHI encoder can be supplied. For the motor body, prepare the spare parts at the machine tool builders.

For maintenance, part replacement, and services in case of failures in the built-in motor (including the encoder), take necessary actions at the machine tool builders. For drive unit, Mitsubishi can offer the afterpurchase servicing as with the general drive unit.

(7) Disposal

1.1.3 Cautions for Mounting Load (Prevention of Impact on Shaft)

[1] When using the servo motor with key way, use the screw hole at the end of the shaft to mount the pulley onto the shaft. To install, first place the double-end stud into the shaft screw holes, contact the coupling end surface against the washer, and press in as if tightening with a nut. When the shaft does not have a key way, use a frictional coupling, etc.

[2] When removing the pulley, use a pulley remover, and make sure not to apply an impact on the shaft.

[3] Install a protective cover on the rotary sections such as the pulley installed on the shaft to ensure safety.

[4] The direction of the encoder installed on the servo motor cannot be changed.

1.1.4 Installation Direction

[1] There are no restrictions on the installation direction. Installation in any direction is possible, but as a standard the motor is installed so that the motor power line and encoder cable cannon plugs (lead-in wires) face downward.

Installation in the standard direction is effective against dripping. Measure to prevent oil and water must be taken when not installing in the standard direction. When the motor is not installed in the standard direction, refer to section "Oil/Water Standards" and take the appropriate measures.

The brake plates may make a sliding sound when a servo motor with magnetic brake is installed with the shaft facing upward, but this is not a fault.

CAUTION

1. Use a flexible coupling when connecting with a ball screw, etc., and keep the shaft core deviation to below the tolerable radial load of the shaft.

2. When directly installing the gear on the motor shaft, the radial load increases as the diameter of the gear decreases. This should be carefully considered when designing the machine.

3. When directly installing the pulley on the motor shaft, carefully consider so that the radial load (double the tension) generated from the timing belt tension is less than the values shown in the table above.

4. In machines where thrust loads such as a worm gear are applied, carefully consider providing separate bearings, etc., on the machine side so that loads exceeding the tolerable thrust loads are not applied to the motor.

5. Do not apply the loads exceeding the tolerable level. Failure to observe this may lead to the axis or bearing damage.

CAUTION

If the cautions in motor installation in the above table are not observed, the motor will have a broken shaft, or the bearing will have a shorter life. Carry out design and installation adjustment so that the load on the motor shaft will be below the tolerable loads mentioned in "Shaft Characteristics".

(1) Direct coupling - Flexible coupling

When coupling the load directly, a flexible coupling is recommended. The benefits of a flexible coupling are as below.

(a) Shaft's angle deviation and core deviation can be absorbed to some extent, so adjustment in motor installation is easier.

However, in the case of single, shaft core deviation cannot be allowed, so it is required to design and adjust so that the shaft cores of the motor and ball screw align. Check the specification of the coupling to use. If the shaft core deviation exceeds the coupling's tolerable level, the motor will have a broken shaft, or the bearing will have a shorter life. Thus, in order to simplify the installation adjustment, use a double flexible coupling.

(b) Less looseness produces less vibration and less noise at the coupling part.

On the other hand, if assembling is loose, lower rigidity may be caused. When using a coupling with lower rigidity, the accuracy in centering the core doesn't have to be high, however, it is undesirable for servo. In order to fully utilize the servo's efficiency to ensure the maximum durability of the equipments, it is required to use a highly rigid coupling, and to fully align the shaft cores in the initial installation. It is also required to select the optimum flexible coupling according to the working conditions, and use it correctly according to the manufacturer's specification manual.

(2) Direct coupling - Rigid coupling

A rigid coupling has benefits such as high rigidity, and relatively lower price. However, shaft core deviation and angle deviation of the motor shaft and ball screw are not allowed, so full attention is required in installing the rigid coupling. Shaft core deviation is desired to be 0.01mm or less. If enough accuracy cannot be ensured, the motor will have a broken shaft, or the bearing will have a shorter life.

Load side

Motor side

0.01mm or less

Also note that the motor side ball screw bearing must be locked so that to avoid the thrust load on the motor shaft due to expansion and contraction of the ball screw.

(3) Gear connection

Gear's accuracy and backlash amount greatly affect on the machine's positioning accuracy and noise during operation.

Thus, according to the machine's specification, appropriately select the accuracy and backlash amount.

In gear connection, it is required to take measures against oil to enter the motor.

1.1.8 Oil/Water Standards

(1) The motor protective format uses the IP type, which complies with IEC Standard.

However, these Standards are short-term performance specifications. They do not guarantee continuous environmental protection characteristics. Measures such as covers, etc., must be taken if there is any possibility that oil or water will fall on the motor, and the motor will be constantly wet and permeated by water. Note that the motor's IP-type is not indicated as corrosion-resistant.

(Note 2) If enough flange size cannot be ensured, ensure the cooling performance by a cooling fan or operate the motor in the state that the motor overheat alarm does not occur.

1.1.10 Cable Stress

[1] Sufficiently consider the cable clamping method so that bending stress and the stress from the cable's own weight is not applied on the cable connection part.

[2] In applications where the servo motor moves, make sure that excessive stress is not applied on the cable.

If the encoder cable and servo motor wiring are stored in a cable bear and the servo motor moves, make sure that the cable bending part is within the range of the optional encoder cable.

Fix the encoder cable and power cable enclosed with the servo motor.

[3] Make sure that the cable sheathes will not be cut by sharp cutting chips, worn or stepped on by workers or vehicles.

The bending life of the encoder cable is as shown below. Regard this with a slight allowance. If the servo motor/spindle motor is installed on a machine that moves, make the bending radius as large as possible.

1.2.2 Balancing the Spindle Motor (Unit)

When a spindle motor is driven at a high speed with unbalance generated on the rotor, the whirling load is generated and the load to the motor's internal bearings is increased. Thus abnormal vibration, and/or damages known as fretting or flaking occurs to the bearings, which may result in shorter bearing life. Therefore, it is important to balance the rotation so that great vibration does not occur during rotation at high speed.

When balancing the spindle motor, perform to the entire rotational objects including the gear, pulley, coupling, etc. that are attached directly on the motor shaft. Provide a balancing mechanism including screw holes on the fittings while measuring the vibration so that the vibration is suppressed to the specified level or lower during high speed rotation.

(1) Fittings for the motor shaft

When you select fittings for the motor shaft, such as a gear, pulley, and coupling, choose those that meet the motor specifications (shaft diameter, rotation speed and output torque).

CAUTION

1. We consider key-less shaft as standard in order to simplify balancing procedure of such as gear, pulley, and coupling.

We recommend you to choose a gear, pulley and coupling that have a fully symmetric shape, and arrange screw holes on their end faces at short and equal intervals in the circumferential direction.

2. Use a fastener such as a shaft lock element to fix those fittings to the motor shaft.

3. When you attach fittings to the motor shaft, be careful not to apply excessive impact by striking with a hammer, etc. This may cause the shaft distortion and bearing damage.

4. When using screws for balancing, apply thread locker on the screws after balancing.

(2) How to measure the unbalance

After attaching the fittings such as gear, pulley, and coupling, carry out no-load operation, and use an accelerometer or vibrometer compatible with frequency analysis to confirm the vibration on the points as illustrated below (on the brackets where the bearings are stored).

Make sure to place the motor on a cushioning mat to avoid vibration to the spindle from external sources during measurement. Reaction torque is generated when accelerating/decelerating the motor, so securely fix the motor with a belt, etc. to avoid rolling during measurement.

CAUTION

1. Make sure to place the motor on a cushioning mat to avoid resonance with surrounding devices during measurement.

2. Always secure the spindle motor body with a belt, etc. because it may roll due to the reaction torque generated during acceleration/deceleration operation.

(3) How to balance the rotation

Find out the rotation speed at which the vibration reaches the maximum, within the actual rotation speed range of the spindle motor. Run the motor at the speed found above and perform balancing to minimize the vibration. When balancing is decided, measure the vibration at different rotation speeds and make a further fine adjustment so that the vibration acceleration generated is always 0.5G (4.9m/s

2

) or less.

(The vibration acceleration of 0.5G is about 4.7

μ m when expressed in terms of the amplitude at the rotation speed of 10,000r/min. The higher the rotation speed is, the smaller the corresponding amplitude becomes.)

1.2.5 Coupling with the Fittings

[1] We recommend you to adjust the dynamic balance (field balance) before fastening a belt.

[2] The position deviation in the axial direction between the motor pulley and spindle side pulley should be as small as possible and perform parallel correcting carefully.

[3] If the selection or tension of belt is incorrect, an excessive force is applied to the shaft end and bearings, which may result in shorter life or damages.

[4] When the load by the belt exceeds the tolerable radial load of the motor, reselect the motor or belt/pulley.

[5] Use an appropriate tension gauge to measure a belt tension.

1.2.6 Installation of Rotary Joint and Coolant Joint (Hollow Shaft Specifications)

Attach the fittings such as pulley, gear, coupling, and coolant joint to the motor output shaft when connecting a spindle motor to a spindle. The incorrect selection of fittings or inadequate installation accuracy can generate abnormal vibration or noise at the coupling. It can also shorten the motor or bearing life, and can damage them (fretting or flaking). Contact the manufacturer with any questions regarding the fittings mentioned above.

Coupling

Coolant joint

Rotary joint

< Reference > Bearing damage

Fretting:

Fretting occurs when contact surfaces produce abrasive red-rust powders, which wear contact surfaces and make small dimples on them. If fretting occurs on the raceway surfaces, dimples are made in the rolling element pitch. Adding vibration load on the contact parts generates a small amplitude oscillation, which forces out lubrication from those parts until there is no lubrication, resulting in significant wear.

Flaking:

Flaking occurs when small pieces of bearing raceway surfaces peel off due to rotation fatigue. It may occur in an early stage due to an excessive load, handling fault, inadequate accuracy of shaft or housing, or a load application by incorrect installation.

(1) Rotary joint

(a) Installation

Rotary joints are used to supply/exhaust high pressure fluid or liquid which is equal to or lower than the atmospheric pressure from the fixed pipe to rotary parts of each mechanical device with no leakage. When attaching a separate external-support type rotary joint to the shaft rear end, structure the rotary joint so that cutting fluid (drain), which is generated when switching ON/OFF the coolant pressure, does not enter inside of the motor.

(i) Provide notches or drain so that the cutting fluid (drain) that has entered the rotary joint housing will not accumulate.

(ii) A rotary joint is a consumable part. Check and replace regularly.

(iii) Many notches must be provided on the housing as a large amount of cutting fluid may leak if the rotary joint is damaged.

(iv) If the motor is used vertically facing down, enhance the drain using parts such as an air purge.

(b) Recommended models of rotary joint

The tables below show the recommended models manufactured by Deublin and Rix. The target models are designed to have these rotary joints attached to the shaft rear end. Contact the manufacturer for details of rotary joint.

When spindle through coolant is used, the thrust load works between the spindle and the motor at the position

A, and between the motor and the rotary joint at the position B in the figure below. Setting the diameter of the pressured area of the coolant joint attached to the end of the motor shaft appropriately makes the thrust load at the position B slightly larger than at the position A, which is effective for coolant pump pulsation.

(3) Coupling

(a) Caution when selecting coupling

Always use a flexible coupling for coupling the spindle and the motor. The flexible coupling is flexible enough to absorb a certain level of radial runout and parallel offset. The flexible coupling has tolerable values for three degrees of freedom (parallel offset, angular misalignment, and axial movement), which realizes a low-vibration and low-noise coupling up to high-speed rotation.

- Tolerable values of parallel offset and angular misalignment:

Absorbs minor misalignments or declinations that were not resolved during alignment.

- Tolerable value of axial movement:

Absorbs elongation of the spindle and motor shaft due to thermal expansion.

(These tolerable values are the standard values for which the coupling does not break. They are not the standard values for which the load is not applied to the spindle or the motor bearing. Thus, in order to rotate up to high-speed with low-vibration and low-noise, the spindle and the motor shaft must be aligned.)

(b) Recommended model of coupling

The table below shows the recommended models manufactured by Miki Pulley and Eagle Industry.

Contact https://www.mikipulley.co.jp/EN/ https://www.ekkeagle.com/en/

(Note) The diaphragm coupling in the table above absorbs the misalignment of the rotary axis with the elastic deformation of the extremely thin metal diaphragm. In addition, there are the features as light weight, no lubrication and high torsional stiffness, so it is recommended as a coupling of a highspeed motor.

(c) Installation of coupling

The following describes how to install a coupling using a product by Miki Pulley. Contact the manufacturer for details of cautions and confirmation.

(i) Make sure that the pressure bolts of the coupling are loosened, and remove rust, dirt, and grease, etc. from the shaft and the inner diameter part of the coupling. (Grease should be wiped away with a cloth, etc., or by degreasing as required.)

(ii) When inserting the coupling into the motor shaft, make sure that no excessive force such as compression, tension, etc. is applied to the element.

(iii) Make sure that the insertion length of the coupling into the motor shaft is kept in the position where the target shaft is in contact with the entire length of the flange of the coupling (LF dimension) as illustrated below. (For the variation of models and the length of LF of each model, contact the manufacturer.)

(iv) Tighten the pressure bolts lightly diagonally by using a bore for rotation prevention.

(v) Apply a dial gauge to the flange edge or outer diameter of the motor side. While rotating the motor shaft lightly by hand, perform hammer adjustment on the flange periphery and edge so that the radial runout will be reduced to as close as zero.

IB-1501229-H

(vi) While performing hammer adjustment, tighten the pressure bolts in sequence. Finally, use a calibrated torque wrench and tighten all the pressure bolts at the appropriate tightening torque as shown in the table below. Also, refer to the following drawing for the sequence to tighten the pressure bolts, and make sure that the bolts are tightened equally.

M8

Tightening torque (N•m)

(vii) Confirm that the pressure bolts of the motor shaft side are tightened to the specified torque and the value of radial runout is small enough.

(viii) Install the motor mounted with coupling to the machine. At this time, adjust the motor mounting position

(inlay) while inserting the coupling into the spindle or feed screw. Check that there is no deformation of the plate spring. Also check that the insertion length of the mating shaft is kept in the position where the target shaft is in contact with the entire length of the flange of the coupling (LF dimension).

20

MDS-E/EH Series Instruction Manual

1 Installation

(ix) The space between flange hubs (S) must be within the permissible error of the axial movement for the standard value. Note that the allowable value assumes that parallel offset and angular misalignment are 0

(zero). Adjust them to achieve values as small as possible. (For the standard value of the S dimension of each model, contact the manufacturer.)

(x) As in the sequence for the pressure bolts on the motor shaft side, sequentially tighten the pressure bolts on the spindle side or the feed screw side. Finally, tighten the bolts at the appropriate tightening torque.

(xi) As a countermeasure against initial loosening of the pressure bolts, it is recommended to additionally tighten the bolts with the appropriate tightening torque after a certain period of operation.

CAUTION

1. Select a coupling that the thrust load will not work on the motor shaft due to a rise of temperature, during cutting, or due to the coolant pressure, etc.

2. Do not hit the coupling with a tool such as a hammer when installing it to the motor shaft so that the impact load will not be applied to the bearing.

3. Do not rely on the flexibility of the coupling only. Make sure to perform alignment also. If the motor rotates with a parallel offset, the bearing may be damaged by fretting wear etc. in a short amount of time.

4. When the motor shaft and the spindle are joined by a coupling, the motor shaft may stay pushed inside the motor.

Confirm that the distance from the surface to install the housing to support the rotary joint to the rear end of the flinger is kept the same before and after inserting the coupling.

1.2.7 Ambient Environment

If you continue to use the spindle motor with dirt such as oil mist and dust adhered, its cooling performance degrades and the motor is unable to fully exercise its performance, which may cause the spindle motor overheat alarm. In some cases this may result in damage to the bearing or cooling fan. Use a filter, etc. to protect the motor from oil mist and dust.

1.2.8 Installation of Spindle Motor

Make sure that the spindle motor is installed so that the motor shaft points from downward to 90° as shown below. When installing upward more than 90°, contact your Mitsubishi Electric dealer.

CAUTION

1. Rubber packing for waterproof is attached on the inner surface of the top cover of terminal block, and on the fan lead.

After checking that the packing is installed, install the top cover so that no foreign objects are stuck in between.

2. When installing a motor on a flange, chamfer(C1) the part of flange that touches inside low part of the motor.

Cooling fan

To yield good cooling performance, provide a space of at least 30mm between the cooling fan and wall. If the motor is covered by a structure and the air is not exchanged, its cooling performance degrades and the motor is unable to fully exercise its performance, which may cause the spindle motor overheat alarm. Do not use the spindle motor in an enclosed space with little ventilation.

1.4.3 Prevention of Entering of Foreign Matter

Treat the cabinet with the following items.

(1) Make sure that the cable inlet is dust and oil proof by using packing, etc.

(2) Make sure that the external air does not enter inside by using head radiating holes, etc.

(3) Close all clearances of the cabinet.

(4) Securely install door packing.

(5) If there is a rear cover, always apply packing.

(6) Oil will tend to accumulate on the top. Take special measures such as oil-proofing to the top so that oil does not enter the cabinet from the screw holds.

(7) After installing each unit, avoid machining in the periphery. If cutting chips, etc., stick onto the electronic parts, trouble may occur.

(8) When using the unit in an area with toxic gases or high levels of dust, protect the unit with air purging (system to blow clean air so that the panel's inner pressure is higher than the outer pressure).

1.5.2 Spindle Side PLG Serial Output Encoder (TS5690, MU1606 Series)

(1) Part configuration

The encoder is configured of a sensor and detection gear. The sensor and detection gear must be used in the designated combination.

These are precision parts, and require care when handling. Do not apply an excessive force on the sensor's detection surface, as this could result in faults. Do not pull and apply a load on the lead wires. Make sure that foreign matters (iron chips, etc.) do not get on the sensor's detection surface or detection gears. If any foreign matter should get on these parts, carefully remove while taking care not to damage the parts. When handling the detection gears, take care not to damage or deform the teeth.

* Thermal sensor terminals

Output connector

*  Thermal sensor terminals are not used

when the encoder is installed on the spindle side.

 

Detection gears

Spindle side PLG serial output encoder TS5690 Series

(2) Installing the detection gears

[1] Install the detection gears so that the first gear's teeth side (Z phase) face the sensor's lead side.

[2] The detection gears and shaft or sleeve should be fixed with shrink fitting. Refer to the following table for the shrink fitting values. The detection gears should be heated evenly between 120 and 150°C using an electric furnace, etc.

[3] Keep the run-out of the outer diameter, when the detection gears are installed on the shaft, to 0.02mm or less.

[4] To remove a detection gear fixed with shrink fitting, use the screw holes opened in the axial direction for pulling

(two M5 screw holes or two M8 screw holes), or push the end with a jig. Carry out this work carefully. Applying excessive force when pulling out the gears could cause the inner diameter of the detection gears to deform.

[5] Before reusing detection gears which have been removed, always measure the inner diameter dimensions, and carefully check that the inner diameter is not deformed, and that the sufficient tightening amount can be secured. Do not reuse the detection gears if the inner diameter is deformed, or if any abnormality such as damage to the teeth is found.

(3) Installing the sensor section

[1] Prepare the notched fitting section at the machine side's installation position to be of the specified dimensions in advance.

[2] With the sensor installation seat's R section butted against the notched fitting section, fix the sensor installation seat with a mounting screw (M4 × 0.8 screws). A locking agent should be applied on the mounting screw before it is tightened.

[3] Fix the sensor with its R section butted against the notched fitting section so that the position relation between the detection gear and sensor is kept constant. This ensures favorable accuracy of the sensor installation.

[4] Keep the deviation of the sensor center and outer diameter center of the detection gear to ±0.25mm or less. If the center deviation cannot be directly measured, set so that the dimension from the sensor installing surface to the outer diameter edge of the detection gears is

19.0±0.25mm. (Some detection gears have thickness at the inner diameter section.)

[5] Make sure that force is not constantly applied on the sensor's lead wires.

[6] Check the gap between the encoder sensor and the gear (0.3±0.05mm).

(4) Installation accuracy diagnosis for spindle side PLG encoder

CAUTION

Do not operate the spindle before performing this installation accuracy diagnosis.

If operated with an improperly installed spindle side PLG encoder, the spindle motor may rotate at high speed.

Always perform this diagnosis before normal operation.

[1] Outline

In this section, check if the installation polarity of spindle side PLG encoder corresponds to the parameter setting, and the gap between the gear and the sensor is appropriate. In a full-closed loop control where the encoder is also installed on the spindle side, it is controlled based on the feedback of the spindle side encoder during the speed command operation (S command). Do not command a normal spindle operation before confirming the installation accuracy of the spindle side encoder.Spindle side PLG encoders (TS5690 Series) have the specified gap from the gear by installing the sensor section on the machine-notched fitting section. Whether a signal is detected correctly or not can be confirmed using the servo diagnosis screen on NC while rotating the spindle motor in an open loop control.

[2] Confirmation of encoder installation polarity

Open the drive monitor/spindle unit on the NC Diagnosis screen, and display "Machine position", "Motor end FB" and "FB error". Confirm that "Machine position" and "Motor end FB" are counted on the same polarity, and that "FB error" is not cumulated while rotating the spindle by hand. When the polarity of "Machine position" and "Motor end

FB" is different and "FB error" is cumulated, change the setting of #13017/bit4 (SP017/bit4). Set the spindle parameter so that the spindle system is in a full-closed loop control during this confirmation.

- #13019 (SP019) Set the encoder resolution of spindle side PLG encoder correctly

- #13031 (SP031) Set to full closed loop control (6200)

[3] Confirmation of encoder installation accuracy

Whether the gap between the sensor section and the gear is ensured correctly or not can be confirmed using the servo diagnosis screen, [PLG diagn] on NC while rotating the spindle motor in an open loop control. Confirm it according to the following procedures.

1) Set the spindle parameter #13018/bit1 (SP018/bit1) to 1 to enable an open loop control.

2) Turn the NC and drive unit power OFF and disconnect the motor side encoder cable only. After that, turn the power ON again.

3) Rotate the spindle by inputting 100r/min command. Although this is the same as normal S command operation, neither the spindle side encoder feed back or the motor side encoder feed back is used for the motor control on the spindle drive unit since the open loop control is set with the spindle parameter.

4) Switch to the [Servo diagn] menu on the NC maintenance screen and change from [Spindle unit] to [PLG diagn]. When all the diagnosis signal bits are constantly at "0", the installation of PLG encoder is normal.

When the diagnosis signal bit is "1", the result of diagnosis is abnormal. Perform troubleshooting following

"[4] Diagnosis and remedy" by reference to the error details and main cause.

5) Set the spindle parameter #13018/bit1 (SP018/bit1) to 0 again and finish the open loop control after stopping the spindle with stop command.

6) Turn the NC and spindle drive unit power OFF, and reconnect the motor side encoder cable as it was.

CAUTION

The spindle PLG diagnosis is only performed during the open loop control operation.Diagnosis screen is displayed even during the normal operation, however, the error detection ("1" display) will not be performed.

1.6 Noise Measures

Noise includes "propagation noise" generated from the power supply or relay, etc., and propagated along a cable causing the power supply unit or drive unit to malfunction, and "radiated noise" propagated through air from a peripheral device, etc., and causing the power supply unit or drive unit to malfunction.

Always implement these noise measures to prevent the peripheral devices and unit from malfunctioning. The measures differ according to the noise propagation path, so refer to the following explanation and take appropriate measures.

(1) General noise measures

(a) Avoid laying the drive unit's power line and signal wire in a parallel or bundled state. Always separate these wires. Use a twisted pair shielded wire for the encoder cable and signal wires such as the communication cable connected with the NC unit, and accurately ground the devices.

(d) Ground the shield of the servo encoder's cable with a cable clamp.

(c) Accurately ground the AC reactor.

(2) Propagation noise measures

Take the following measures when noise generating devices are installed and the power supply unit or drive unit could malfunction.

(a) Install a surge killer on devices (magnetic contacts, relays, etc.) which generate high levels of noise.

(b) Install a power line filter in the stage before the power supply unit.

(c) Install a ferrite core on the signal wire.

(d) Ground the shield of the servo encoder's cable with a cable clamp.

(e) Wire the spindle PLG encoder cable away from other wires.

(3) Measures against radiated noise

The types of propagation paths of the noise and the noise measures for each propagation path are shown below.

Measures

When devices such as instrument, receiver or sensor, which handle minute signals and are easily affected by noise, or the signal wire of these devices, are stored in the same panel as the drive units and the wiring is close, the device could malfunction due to airborne propagation of the noise. In this case, take the following measures.

(a) Install devices easily affected as far away from the drive units as possible.

(b) Lay devices easily affected as far away from the signal wire of the drive unit as possible.

(c) Avoid laying the signal wire and power line in a parallel or bundled state.

(d) Insert a line noise filter on the input/output wire or a radio filter on the input to suppress the noise radiated from the wires.

(e) Use a shield wire for the signal wire and power line, or place in separate metal ducts.

If the signal wire is laid in parallel to the power line, or if it is bundled with the power line, the noise could be propagated to the signal wire and cause malfunction because of the magnetic induction noise or static induction noise. In this case, take the following measures.

(a) Install devices easily affected as far away from the drive unit as possible.

(b) Lay devices easily affected as far away from the signal wire of the drive unit as possible.

(c) Avoid laying the signal wire and power line in a parallel or bundled state.

(d) Use a shield wire for the signal wire and power line, or place in separate metal ducts.

If the power supply for the peripheral devices is connected to the power supply in the same system as the drive units, the noise generated from the power supply unit could back flow over the power line and cause the devices to malfunction. In this case, take the following measures.

(a) Install a radio filter on the power supply unit's power line.

(b) Install a power filter on the power supply unit's power line.

If a closed loop is created by the peripheral device and drive unit's grounding wire, a leakage current could flow and cause the device to malfunction.

In this case, change the device grounding methods and the grounding place.

2 Wiring and Connection

WARNING

1. Wiring work must be done by a qualified technician.

2. Wait at least 15 minutes after turning the power OFF and check the voltage with a tester, etc., before starting wiring.

Failure to observe this could lead to electric shocks.

3. Securely ground the drive units and servo/spindle motor.

4. Wire the drive units and servo/spindle motor after installation. Failure to observe this could lead to electric shocks.

5. Do not damage, apply forcible stress, place heavy items on the cables or get them caught. Failure to observe this could lead to electric shocks.

6. Always insulate the power terminal connection section. Failure to observe this could lead to electric shocks.

CAUTION

1. Correctly and securely perform the wiring. Failure to do so could result in runaway of the servo/spindle motor or injury.

2. Do not mistake the terminal connections.

3. Do not mistake the polarity ( + , - ). Failure to observe this item could lead to ruptures or damage, etc.

4. Adjust the cable not to have an excess length. The excessive length could generate noise.

5. Do not mistake the direction of the diodes for the surge absorption installed on the DC relay for the motor brake and contactor (magnetic contactor) control. The signal might not be output when a failure occurs.

6. Electronic devices used near the drive units may receive magnetic obstruction. Reduce the effect of magnetic obstacles by installing a noise filter, etc.

7. Do not install a phase advancing capacitor, surge absorber or radio noise filter on the power line (U, V, W) of the servo/ spindle motor.

8. Do not modify this unit.

9. If the connectors are connected incorrectly, faults could occur. Make sure that the connecting position and the connection are correct.

10. When grounding the motor, connect to the protective grounding terminal on the drive units, and ground from the other protective grounding terminal. (Use one-point grounding)

Do not separately ground the connected motor and drive unit as noise could be generated.

11. When the main grounding plate or the part to install a grounding cable is painted, remove the paint before grounding the cable. The electrical connection becomes insufficient and noise could be generated.

2.3 NC and Drive Unit Connection

2.3.1 Connection of Optical Communication Cables

Connect the optical communication cables from the NC to the each drive unit so that they run in a straight line from the

NC to the drive unit that is a final axis. And up to 16 axes can be connected per system.

Note that the number of connected axes is limited by the NC.

CAUTION

1. Connect the NC and the drive units by the optical communication cables. The distance between the NC and the final drive unit must be within 30m and the specified bending radius (for wiring inside panel: 25mm, and for wiring outside panel: 50mm) or more.

2. For the main circuit wiring of the drive unit and power supply unit, the drive unit of 200V series is to be wired with MDS-

D2-CV, and the drive unit of 400V series is to be wired with MDS-EH-CV.

POINT

Axis Nos. are determined by the rotary switch for setting the axis No. (Refer to section "Setting the rotary switch".) The axis

No. has no relation to the order for connecting to the NC.

(1) When using one power supply unit

Connect the largest-capacity spindle drive unit to the final axis of the NC communication bus in order to control the power supply unit. The spindle drive unit must be installed adjacent to the power supply unit. In the system with servo only, a servo drive unit for controlling unbalance axis must be installed in the same manner in the same way.

2.5 Connection of Power Supply

CAUTION

1. Make sure that the power supply voltage is within the specified range of each unit. Failure to observe this could lead to damage or faults.

2. For safety purposes, always install a circuit protector, and make sure that the circuit is cut off when an error occurs or during inspections.

3. The wire size will differ according to each drive unit capacity.

4. For safety purposes, always install a magnetic contactor (contactor) on the main circuit power supply input. Large rush currents will flow when the power is turned ON.

5. A semiconductor element is used in the power supply unit's magnetic contact drive circuit, and a surge absorber is installed to protect the element. Therefore, a leakage current of approx. 15mA is passed. Confirm that the exciting coil in the magnetic contact will not function at 15mA or less.

2.5.1 Power Supply Input Connection

2.6 Wiring of the Motor Brake

2.6.1 Wiring of the Motor Magnetic Brake

The magnetic brake of servo motors with a magnetic brake is controlled by the motor brake control connector (CN9 and

CN20) on the servo drive unit. The servo drive unit releases the brake when the motor is ON. (Servo ON means when torque is generated in the motor.) When using safe brake control (SBC), refer to 3.3. SBC (Safe Brake Control). Not that for safe brake control the wiring and control sequence are different to the contents in this section.

(1) When using a motor brake for one axis

As shown in the illustration below, an external power supply circuit is controlled by the CN20 connector output.

Dynamic brake unit is controlled simultaneously for the servo drive unit with the capacity of MDS-E-V1-320W or larger and MDS-EH-V1-160W or larger. Refer to "Dynamic brake unit wiring" for details.

CAUTION

1. CN20 connector and the brake can be connected directly because the servo drive unit contains the surge absorber.

2. The brakes cannot be released just by connecting motor brake terminal. 24VDC must be supplied.

3. For the 24V power supply used in the motor brake circuit, use the one separated from the 24V power supply for the control circuit.

4. Only one axis can be controlled by the motor brake with CN20. The maximum brake tolerable current value of the CN20 is 1.7A.

CAUTION

When using SBC (Safe Brake Control) function, the CN9 connector is dedicated to the M axis and the motor brakes cannot be connected in parallel.

Refer to "3.3 SBC (Safe Brake Control)" for details.

< Caution in use of MDS-E/EH-V2/V3 >

It is required to input a servo OFF command to all axes in order to turn the brake ON with a motor brake control output (CN20) of drive unit. Input the servo OFF command to an axis cannot turn the brake ON. Therefore, when performing a control to fix the position with the motor brake by the servo OFF command during the motor stop for

PLC axis, use 1-axis drive unit.

During emergency stop, the servo OFF is applied to all axes at same time, so a brake control is not affected.

POINT

Using the high-speed ready ON sequence, set the parameter for all the axes including the spindle. Especially when it is not set for the power supply control axis, power supply will not work at high-speed sequence.

CAUTION

When SV017/bit2=1, SP017/bit2=1 is set, for the model using an external dynamic brake, the Ready completion will be delayed by 10ms to ensure the external contactor operation time.

(4) Control during the servo OFF command

When a servo OFF command is input by an NC sequence input, the motor brake turns ON simultaneously when the motor ON is shut off. Note that the vertical axis drop prevention control is not validated, so a drop due to the brake operation lag occurs. When the servo OFF is canceled, a drop due to an uncontrolled state does not occur.

This function can also be used for judging whether the current machine-end speed reaches the specified speed.

The specified speed output signal is output to the digital signal output 2 (MPO2). Refer to the next page for details, because the configuration of the parameters differs from the servo to spindle. For the 2-axis or 3-axis drive unit, it is required to set the parameter to the all axes. The signal output turns ON when the all axes satisfy the conditions

(theoretical product output).

2.7.3 Spindle Coil Changeover

There are spindle motors capable of coil changeover control, which enables favorable characteristics to be attained from low speeds to high speeds by changing two types of coils.

(1) Coil changeover control

The speed at which to change the coils is detected by the spindle drive according to the value set with spindle parameter SP028. This is conveyed to the NC with a speed detection (SD) signal. The NC judges the other conditions (coil fixed, etc.), and issue a coil changeover command to the spindle drive with the L coil selection command (LCS).

To prevent the contactor from varying, the hysteresis set with SP029 is applied on the speed when changing from the low-speed coil to the high-speed coil and the high-speed coil to the low-speed coil.

(2) Protective functions

[1] Gate shutoff after a winding changeover

When the L-coil selection command (LCS) is used to perform low-speed winding -> high-speed winding switching, or vice-versa, the gate is shut off during contactor operation time in order to protect the spindle drive unit's main circuit. The gate shutoff time is determined by the "Coil changeover gate cutoff timer" (SP114) setting. The standard time setting should be used, as a shorter time can cause contactor burn damage.

(Refer to "Spindle control output 5" Coil changing (bit 6) for details.)

【

#13114

】

Set the time required to cut off the gate when turning OFF/ON the coil switch contactor.

The value should be longer than the coil switch contactor's OFF/ON time.

The standard setting is "150".

---Setting range---

0 to 3500 (ms)

[2] Current limit after coil changeover

Following a coil changeover, the current is limited (SP116) for the period specified by the current limit timer

(SP115) in order to stabilize control. Because position loop control (synchronous tap, C-axis control, etc.) that occurs immediately after a coil changeover will result in unstable control, be sure that position commands specified by the sequence is input after the current limit is cancelled.

【

Set the time required to limit the current immediately after the coil switch contactor ON/OFF is completed and the gate is turned ON.

The standard setting is "250".

3 Safety Function

3.2 STO (Safe Torque Off) Function

CAUTION

Device manufacturer accepts responsibility for all the risk assessments and related residual risks. The followings are the residual risks relevant to the STO function. Mitsubishi Electric will not accept liability for any accidents such as damage or injury caused by such residual risks.

1. STO function is a function to remove the energy of the motor electronically and not the function to shut off the input power to the drive unit or the connection between the drive unit and the motor physically. Therefore, the risk for electric shocks cannot be eliminated with the STO function. To prevent electric shocks, use the EMG function.

2. STO function is a function to disable the energy to the motor electronically. It does not guarantee the shutoff or the procedure for the deceleration control of the motor.

Read carefully the manual of each safety-related device for the correct installation, wiring, and adjustment.

For all the safety-related relay, sensor, etc., use the one which satisfies the safety standards. TUV SUD has confirmed that the safety-related parts by Mitsubishi Electric described in this manual satisfy EN ISO13849-1 Category 3, PL d.

3. Even though the STO function is enabled by the STO switch, voltage may still be residual at the servo motor for the delay specific to the device.

4. Safety is not guaranteed until the installation or adjustment for the safety-related parts in the system has been completed.

5. When replacing the drive unit, make sure that the new product is the same as the one before the replacement. After the installation, be sure to confirm the performance of the safety function before operating the system.

6. Perform all the risk assessments and safety level certifications for the whole device and system. The use of a third-party certifier such as TUV SUD is recommended as a final safety certification of the system.

7. To prevent the accumulation of failure, perform an appropriate safety confirmation check at regular intervals as required by the safety standards. The safety confirmation check must be performed at least once a day regardless of the safety level of the system.

8. When up-and-down short circuit is occurred to the power module of the drive unit, the servo motor shaft rotates for up to

0.5 revolution.

9. Be sure to supply the STO input signal (STO1, STO2) from one power supply. If the power is divided, STO shutoff state may not be realized due to a malfunction of the STO function caused by a sneak current.

DANGER

Improper installation of a safety-related device or a system could cause a operation state without safety guaranteed and may lead to a serious or fatal accident.

Preventive measure against the above danger

As described in IEC 61800-5-2, the STO (Safe Torque Off) function is a function not to supply a energy from a drive unit to a motor and does not guarantee that a motor is not moved by an external force and other influence.

Take safety measure such as brake or counter balance additionally when the external force is acted on by the motor itself.

3 Safety Function

(2) Wiring of the motor magnetic brake

The magnetic brake of servo motors with a magnetic brake is controlled by the motor brake control connector (CN9 and CN20) on the servo drive unit. The servo drive unit releases the brake when the motor is ON. (Servo ON means when torque is generated in the motor.) It also contains duplex contacts for motor magnetic brake control to support the safe brake control (SBC).

[1] Motor brake control connector (CN20) output circuit (When using the brake of L axis)

As shown in the illustration below, an external power supply circuit is controlled by the CN20 connector output.

Dynamic brake unit is controlled simultaneously for the servo drive unit with the capacity of MDS-E-V1-320W or larger and MDS-EH-V1-160W or larger. Refer to "Dynamic brake unit wiring" for details.

CAUTION

1. For SBC, the brake control of the CN20 connector is dedicated to the L axis and the brake control of the CN9 connector is dedicated to the M axis.

2. The maximum brake tolerable current value of CN20 is 1.7A.

3. The brakes cannot be released just by connecting motor brake terminal. 24VDC must be supplied.

4. For the 24V power supply used in the motor brake circuit, use the one separated from the 24V power supply for the control circuit.

When the base reference mark interval (SV130) and the reference mark's auxiliary interval are in the specified relationship, the distance-coded reference scale is judged to be connected.

Following is the specified relationship.

(SV130×1000) / SV131 >= 4 (No remainder)

4 Setup

(2) Setting of the distance-coded reference check function

If The reference marks are checked at four points by the basic point computer processing, the basic point can be recreated almost certainly. If you would like to strengthen the check further, set the distance-coded reference check function, which executes the relation check with a coordinate of the motor side encoder during the basic point calculation after the power-on.

When an error occurs, "Alarm 42" is detected. The battery option is required to use this function since the motor side encoder is under the absolute position control.

< Initial setup of the distance-coded reference check >

Performed this initial setup at the start of the system setup, linear scale exchange, or motor exchange.

(1) Complete the setup of the distance-coded reference scale.

( Complete the base specification setting, and enable the basic point establishment.)

(2) Turn the power ON again after setting "SV137 = -1".

( Under a state of the distance-coded reference check initial setup warning "A3".)

(3) Perform the reference point return.

(4) Conform that the warning "A3" turns OFF.

(5) Set the value of "Rn", "Pn" and "MPOS" to "SV134", "SV135" and "SV136" on the drive monitor.

(6) When SV137=32767, the distance-coded reference check function is disabled.

【

#2334

】

【

#2335

】

【

#2336

】

Set this parameter to operate distance-coded reference check when using distance-coded reference scale.

During the distance-coded reference check initial setup (SV137:RAER=-1), set the following items on the NC drive monitor screen after the distance-coded reference check initial setup warning A3 turns OFF.

SV134=Rn, SV135=Pn, SV136=MPOS

【

#2337

】

For the distance-coded reference check function when using distance-coded reference scale, set the allowable gap from the reference point position data calculated by the main side encoder. When the gap exceeds the allowable range, reference point created by distance-code is judged as wrong and detects alarm 42.

The standard setting value is "basic reference mark interval (SV130) / 4".

SV137=0 setting carries out the same operation as the standard setting value.

SV137=-1 setting enables the distance-coded reference initial set up mode and displays setting values of SV134 to SV136 on NC drive monitor.

To enable the distance-coded reference check function, SV081/bit3=1setting and a battery option are needed.

4.2.4 Setting of Speed Command Synchronous Control

This section explains about the setting of the speed command synchronous control of the full closed loop control. The servo parameter setting during the position command synchronous control is same as single axis.

【

#2225(PR)

】

Set the position encoder type for the secondary axis to "D". The same value is set for 2-axis drive unit, 3-axis drive unit and two 1-axis drive units.

bit F-C : pen Position encoder

Speed command synchronization control primary axis : pen=A

Speed command synchronization control secondary axis : pen=D

CAUTION

1. When performing the speed command synchronous control with 2-axis drive unit (MDS-E/EH-V2), make sure to set Laxis as primary axis. When performing the speed command synchronous control with 3-axis drive unit (MDS-E-V3), make sure to set L-axis as primary axis and M-axis as secondary axis.

2. The rectangular waveform output scale is not available for the speed command synchronous control.

3. The distance-coded reference scale is not available for the speed command synchronous control.

4. When using speed command synchronization control, the following setting of NC side is required.

- Set bit3 of #1281:ext17 to "0" and disable the synchronous error automatic correction function at servo ON.

- Set #1064:svof of the primary axis and secondary axis to "0" and disable the error correction at servo OFF for both axes.

- The parameter settings related to the machine error compensation such as quadrant protrusion compensation must be the same for the primary axis and secondary axis.

4.2.6 Servo Parameters

The parameters with "(PR)" requires the CNC to be turned OFF after the settings. Turn the power OFF and ON to enable the parameter settings.

(PR)

(PR)

#2201 SV001 PC1 Motor side gear ratio

Set the gear ratio in the motor side when there is the gear between the servo motor's shaft and machine (ball screw, etc.).

For the rotary axis, set the total deceleration (acceleration) ratio.

Even if the gear ratio is within the setting range, the electronic gears may overflow and an initial parameter error (servo alarm 37) may occur.

For linear servo system

Set to "1".

---Setting range---

1 to 32767

#2202 SV002 PC2 Machine side gear ratio

Set the gear ratio in the machine side when there is the gear between the servo motor's shaft and machine

(ball screw, etc.).

For the rotary axis, set the total deceleration (acceleration) ratio.

Even if the gear ratio is within the setting range, the electronic gears may overflow and an initial parameter error (servo alarm 37) may occur.

For linear servo system

Set to "1".

---Setting range---

1 to 32767

#2203 SV003 PGN1

Set the position loop gain. The standard setting is "33".

The higher the setting value is, the more accurately the command can be followed, and the shorter the settling time in positioning gets, however, note that a bigger shock will be applied to the machine during acceleration/deceleration.

When using the SHG control, also set SV004 (PGN2) and SV057 (SHGC).

When using the OMR-FF control, set the servo rigidity against quadrant projection or cutting load, etc. For the tracking ability to the command, set by SV106(PGM).

---Setting range---

1 to 200 (rad/s)

Position loop gain 1

#2204 SV004 PGN2

When performing the SHG control, set the value of "SV003 x 8/3" to "SV004".

When not using the SHG control, set to "0".

When using the OMR-FF control, set to "0".

Related parameters: SV003, SV057

---Setting range---

0 to 999 (rad/s)

Position loop gain 2

#2205 SV005 VGN1 Speed loop gain 1

Set the speed loop gain.

The higher the setting value is, the more accurate the control will be, however, vibration tends to occur.

If vibration occurs, adjust by lowering by 20 to 30%.

The value should be determined to the 70 to 80% of the value at which the vibration stops.

The value differs depending on servo motors.

Aim at the standard value determined by the servo motor type and load inertia ratio to adjust.

---Setting range---

1 to 30000

IB-1501229-H 132

MDS-E/EH Series Instruction Manual

4 Setup

#2206 SV006 VGN2 Speed loop gain 2

Set the speed loop gain at the motor limitation speed VLMT (maximum rotation speed x 1.15) with

"VCS(SV029: Speed at the change of speed loop gain)".

Use this to suppress noise at high speed rotation during rapid traverse, etc. Then, the speed loop gain decreases at faster speed than the setting value of VCS. When not using, set to "0".

#2207 SV007 VIL

Set this when the limit cycle occurs in the full-closed loop, or overshooting occurs in positioning. The speed loop delay compensation method can be selected with SV027/bit1,0.

Normally, use "Changeover type 2". Changeover type 2 controls the occurrence of overshooting by lowering the speed loop lead compensation after the position droop gets 0.

When setting this parameter, make sure to set the torque offset (SV032).

---Setting range---

0 to 32767

Speed loop delay compensation

#2208 SV008 VIA Speed loop lead compensation

Set the gain of the speed loop integral control.

Standard setting: 1364

Standard setting in the SHG control: 1900

Adjust the value by increasing/decreasing this by about 100 at a time.

Raise this value to improve contour tracking accuracy in high-speed cutting.

Lower this value when the position droop does not stabilize (when the vibration of 10 to 20Hz occurs).

---Setting range---

1 to 9999

#2209 SV009 IQA Current loop q axis lead compensation

Set the fixed value of each motor.

Set the standard value for each motor described in the standard parameter list.

---Setting range---

Current loop d axis gain

#2213 SV013 ILMT

Set the current (torque) limit value in a normal operation.

This is a limit value in forward run and reverse run (for linear motors: forward and reverse direction).

When the standard setting value is "800", the maximum torque is determined by the specification of the motor.

Set this parameter as a proportion (%) to the stall current.

---Setting range---

0 - 999 (Stall current %)

Current limit value

#2214 SV014 ILMTsp Current limit value in special control

Set the current (torque) limit value in a special operation (absolute position initial setting, stopper control and etc.).

This is a limit value in forward and reverse directions.

Set to "800" when not using.

Set this parameter as a proportion (%) to the stall current.

---Setting range---

0 - 999 (Stall current %)

However, when SV084/bitB=1, the setting range is from 0 to 32767 (Stall current 0.01%).

#2215 SV015 FFC Acceleration rate feed forward gain

When a relative error in synchronous control is too large, set this parameter to the axis that is delaying.

The standard setting is "0". The standard setting in the SHG control is "100".

To adjust a relative error in acceleration/deceleration, increase the value by 50 at a time.

---Setting range---

0 to 999 (%)

#2216 SV016 LMC1 Lost motion compensation 1

Set this parameter when the protrusion (that occurs due to the non-sensitive band by friction, torsion, backlash, etc.) at quadrant change is too large. This sets the compensation torque at quadrant change (when an axis feed direction is reversed) by the proportion (%) to the stall torque. Whether to enable the lost motion compensation and the method can be set with other parameters.

Type 2: When SV027/bit9, 8=10 (Compatible with obsolete type)

Set the type 2 method compensation torque. The standard setting is double the friction torque.

Related parameters: SV027/bit9,8, SV033/bitF, SV039, SV040, SV041, SV082/bit2

Type 3: When SV082/bit1=1

Set the compensation torque equivalent of dynamic friction amount of the type 3 method compensation amount. The standard setting is double the dynamic friction torque.

Related parameters: SV041, SV082/bit2,1, SV085, SV086

To vary compensation amount according to the direction.

When SV041 (LMC2) is "0", compensate with the value of SV016 (LMC1) in both +/-directions.

If you wish to change the compensation amount depending on the command direction, set this and

SV041 (LMC2).

(SV016: + direction, SV041: - direction. However, the directions may be opposite depending on other settings.)

When "-1" is set, the compensation will not be performed in the direction of the command.

---Setting range---

-1 to 200 (Stall current %)

Note that when SV082/bit2 is "1", the setting range is between -1 and 20000 (Stall current 0.01%).

(3) Spindle speed settings for Z-phase detection when starting

At the first spindle rotation after the power ON (including turning the power ON again only for NC), the spindle rotates at the speed of setting parameters during Z-phase detection for the encoder. Set the rotation speed.

【

#3106

】

bit F : Spindle zero point detection with contactless switch

0: Normal

1: Enable spindle zero point detection using proximity switch

【

#3109

】

For the first S command after power is turned ON, the spindle rotates at the speed of setting value for this parameter until Z phase is detected twice.

When "#3106/bitF = 1" (Spindle zero point proximity switch detection enabled), also proximity switch is detected.

(Note) When spindle zero point proximity switch detection is enabled, the rotation direction of the orientation/zero point return (synchronous tapping, spindle/C axis) will follow Z phase detection direction. And the speed will follow Z phase detection speed.

---Setting range---

< Cautions for starting the spindle >

The test operation (acceleration/deceleration, orientation) of the spindle can be executed by setting the initial parameters, however, check the spindle operation with caution.

Check the wiring and ensure the safety of the surroundings before starting the operation.

Do not operate at high-speed rotation at first. After checking that there are no problems as abnormal noise, vibration, etc. from the spindle at start up with no-load and small S commands, raise the S commands gradually.

When vibration or abnormal noise occurs during the test operation, adjust or set the speed gain or the notch filter.

For the first check of the orientation, the orientation should be executed gradually from small S commands.

4.3.3 Spindle Parameters

These parameters are sent to the spindle drive unit when the NC power is turned ON. The standard parameters are designated with the "Spindle parameter setting list" enclosed when the spindle motor is delivered. There may be cases when the machine specifications are unclear, so the parameters determined by the machine specifications should be confirmed by the user.

The parameters with "(PR)" requires the CNC to be turned OFF after the settings. Turn the power OFF and ON to enable the parameter settings.

#13001 SP001 PGV

Set the position loop gain for "Non-interpolation" control mode.

When the setting value increases, the command tracking ability will enhance and the positioning settling time can be shorter. However, the impact on the machine during acceleration/deceleration will increase.

Use the selection command, the control mode "bit 2, 1, 0 = 000" in control input 4.

(Note) The control mode is commanded by NC.

---Setting range---

1 to 200 (rad/s)

Position loop gain non-interpolation mode

#13002 SP002 PGN

Set the position loop gain for "interpolation" control mode.

When the setting value increases, the command tracking ability will enhance and the positioning settling time can be shorter. However, the impact on the machine during acceleration/deceleration will increase.

Use the selection command, the control mode "bit 2, 1, 0 = 010 or 100" in control input 4.

(Note) The control mode is commanded by NC.

When carrying out the SHG control, set SP035/bitC to "1".

---Setting range---

1 to 200 (rad/s)

Position loop gain interpolation mode

#13003 SP003 PGS Position loop gain spindle synchronization

Set the position loop gain for "spindle synchronization" control mode.

When the setting value increases, the command tracking ability will enhance and the positioning settling time can be shorter. However, the impact on the machine during acceleration/deceleration will increase.

Use the selection command, the control mode "bit 2, 1, 0 = 001" in control input 4.

(Note 1) The control mode is commanded by NC.

When carrying out the SHG control, set SP036/bit4 to "1".

(Note 2) Set the same value for the basic and synchronous spindles in spindle synchronization.

---Setting range---

1 to 200 (rad/s)

#13004 SP004

Not used. Set to "0".

#13005 SP005 VGN1 Speed loop gain 1

Set the speed loop gain.

Set this according to the load inertia size.

The higher setting value will increase the accuracy of control, however, vibration tends to occur.

If vibration occurs, adjust by lowering by 20 to 30%.

The final value should be 70 to 80% of the value at which the vibration stops.

---Setting range---

1 to 9999

#13006 SP006 VIA1 Speed loop lead compensation 1

Set the speed loop integral control gain.

The standard setting is "1900". Adjust the value by increasing/decreasing the value by about 100.

Raise this value to improve the contour tracking accuracy in high-speed cutting.

Lower this value when the position droop does not stabilize (when the vibration of 10 to 20Hz occurs).

---Setting range---

1 to 9999

#13014 SP014 PY1

Set the minimum value for the variable excitation rate. The standard setting is "50".

Set to "0" when using an IPM spindle motor.

If noise including gear noise is loud, select a small value. However, a larger setting value is more effective for impact response.

(Note) When setting a value at "50 or more", check if there is no problem with gear noise, motor excitation noise, vibration during low-speed rotation or vibration when the servo is locked during orientation stop, etc.

When setting a value at "less than 50", check if there is no problem with the impact load response or rigidity during servo lock.

#13016 SP016 DDT

Set the single-rotation position alignment deceleration rate for orientation stopping, phase alignment while rotating and switching from non-interpolation mode to spindle synchronization mode while rotating.

When the load inertia is larger, the setting value should be smaller.

When the setting value is larger, the orientation in-position and single-rotation position alignment complete faster, but the impact applied on the machine will increase.

To change the deceleration rate only during rotation command (command F Δ T ≠ 0), set this parameter together with SP070 (KDDT).

---Setting range---

#13096 SP096 SDW Speed slowdown allowable width

When the spindle slows down due to multiple cutting, set the processable speed as percentage against the

(E.g.) When set to 90 [%]

If S1000 is commanded, the speed reduced by 900r/min (=1000r/min × 90%) is the allowable lower limit.

Thus if the spindle speed reduces to 100r/min or below, the alarm will occur.

5.2.2 Speed Loop Gain

(1) Setting the speed loop gain

The speed loop gain 1 (SV005: VGN1) is an important parameter for determining the responsiveness of the servo control. During servo adjustment, the highest extent that this value can be set to becomes important. The setting value has a large influence on the machine cutting precision and cycle time.

[1] Refer to the following standard VGN1 graphs and set the standard VGN1 according to the size of the entire load inertia (motor and machine load inertia).

[2] If the standard VGN1 setting value is exceeded, the current command fluctuation will increase even if the speed feedback fluctuates by one pulse. This can cause the machine to vibrate easily, so set a lower value to increase the machine stability.

< When machine resonance does not occur at the standard VGN1 >

Set the standard VGN1. Use the standard value if no problem (such as machine resonance) occurs. If sufficient cutting precision cannot be obtained at the standard VGN1, VGN1 can be raised above the standard value as long as a 70 percent margin in respect to the machine resonance occurrence limit is maintained. The cutting accuracy can also be improved by adjusting with the disturbance observer.

< When machine resonance occurs at the standard VGN1 >

Machine resonance is occurring if the shaft makes abnormal sounds when operating or stopping, and a fine vibration can be felt when the machine is touched while stopped. Machine resonance occurs because the servo control responsiveness includes the machine resonance points. (Speed control resonance points occur, for example, at parts close to the motor such as ball screws.) Machine resonance can be suppressed by lowering VGN1 and the servo control responsiveness, but the cutting precision and cycle time are sacrificed.

Thus, set a vibration suppression filter and suppress the machine resonance (Refer to section "Vibration

Suppression Measures"), and set a value as close as possible to the standard VGN1. If the machine resonance cannot be sufficiently eliminated even by using a vibration suppression filter, then lower the VGN1.

【

#2205

】

Set the speed loop gain.

The higher the setting value is, the more accurate the control will be, however, vibration tends to occur.

If vibration occurs, adjust by lowering by 20 to 30%.

The value should be determined to the 70 to 80% of the value at which the vibration stops.

The value differs depending on servo motors.

Aim at the standard value determined by the servo motor type and load inertia ratio to adjust.

---Setting range---

1 to 30000

POINT

Suppressing the resonance with the vibration suppression function and increasing the VGN1 setting is effective for adjusting the servo later.

(2) Setting the speed loop lead compensation

The speed loop lead compensation (SV008: VIA) determines the characteristics of the speed loop mainly at low frequency regions. 1364 is set as a standard, and 1900 is set as a standard during SHG control. The standard value may drop in respect to loads with a large inertia.

When the VGN1 is set lower than the standard value because the load inertia is large or because machine resonance occurred, the speed loop control band is lowered. If the standard value is set in the leading compensation in this status, the leading compensation control itself will induce vibration. In concrete terms, a vibration of 10 to 20Hz could be caused during acceleration/ deceleration or stopping, and the position droop waveform could be disturbed when accelerating to a constant speed and when stopped. (Refer to lower left drawing)

This vibration cannot be suppressed by the vibration suppression functions. Lower the VIA in increments of 100 from the standard setting value. Set a value where vibration does not occur and the position droop waveform converges smoothly. Because lowering the VIA causes a drop in the position control's trackability, the vibration suppression is improved even when a disturbance observer is used without lowering the VIA. (Be careful of machine resonance occurrence at this time.)

Vibration waveform with lead compensation control Adjusted position droop waveform

If VIA is lowered, the position droop waveform becomes smooth and overshooting does not occur.

However, because the trackability in respect to the position commands becomes worse, the positioning time and accuracy are sacrificed. VIA must be kept high (set the standard value) to guarantee precision, especially in highspeed contour cutting (generally F = 1000 or higher). In other words, in a machine aiming for high speed and high accuracy, a large enough value must be set in VGN1 so that VIA does not need to be lowered. When adjusting, the cutting precision will be better if adjustment is carried out to a degree where overshooting does not occur and a high

VIA is maintained, without pursuing position droop smoothness.

If there are no vibration or overshooting problems, the high-speed contour cutting precision can be further improved by setting the VIA higher than the standard value. In this case, adjust by raising the VIA in increments of 100 from the standard value.

Setting a higher VIA improves the trackability regarding position commands in machines for which cycle time is important, and the time to when the position droop converges on the in-position width is shortened.

It is easier to adjust the VIA to improve precision and cycle time if a large value (a value near the standard value) can be set in VGN1, or if VGN1 can be raised equivalently using the disturbance observer.

Set the gain of the speed loop integral control.

Standard setting: 1364

Adjust the value by increasing/decreasing this by about 100 at a time.

Lower this value when the position droop does not stabilize (when the vibration of 10 to 20Hz occurs).

---Setting range---

1 to 9999

5.2.3 Position Loop Gain

(1) Setting the position loop gain

The position loop gain 1 (SV003: PGN1) is a parameter that determines the trackability to the command position. 33 is set as a standard. Set the same position loop gain value between interpolation axes.

When PGN1 is raised, the trackability will be raised and the settling time will be shortened, but a speed loop that has a responsiveness that can track the position loop gain with increased response will be required. If the speed loop responsiveness is insufficient, several Hz of vibration or overshooting will occur during acceleration/ deceleration. Vibration or overshooting will also occur when VGN1 is smaller than the standard value during VIA adjustment, but the vibration in the position loop occurs generally 10Hz or less. (The VIA vibration occurs from 10 to

20Hz.) When the position control includes machine resonance points (Position control machine resonance points occur at the tool end parts, etc.) because of insufficient machine rigidity, the machine will vibrate during positioning, etc. In either case, lower PGN1 and adjust so that vibration does not occur.

If the machine also vibrates due to machine backlash when the motor stops, the vibration can be suppressed by lowering the PGN1 and smoothly stopping.

If SHG control is used, an equivalently high position loop gain can be maintained while suppressing these vibrations. Adjust SHG control by raising the gain gradually after setting PGN1 as 1/2 a value of PGN1 at which a vibration does not occur under the normal control. If the PGN1 setting value is more than 1/2 of the normal control

PGN1 when SHG control is used, there is an improvement effect in position control. (Note that for the settling time the improvement effect is at 1/

2

or more.)

【

#2203

】

Set the position loop gain. The standard setting is "33".

The higher the setting value is, the more accurately the command can be followed, and the shorter the settling time in positioning gets, however, note that a bigger shock will be applied to the machine during acceleration/deceleration.

When using the SHG control, also set SV004 (PGN2) and SV057 (SHGC).

(2) Setting the position loop gain for spindle synchronous control

During spindle synchronous control (synchronous tapping control, etc.), there are three sets of position loop gain parameters besides the normal control.

【

】

Set the position loop gain during spindle synchronization control (synchronous tapping and synchronization control with spindle C-axis).

Set the same value as that of the position loop gain for spindle synchronous tapping control.

【

When using SHG control during spindle synchronous control (synchronous tapping and synchronization control with spindle C-axis), set this parameter with SV049 (PGN1sp) and SV058

(SHGCsp).

Make sure to set the value 8/3 times that of SV049.

When not using the SHG control, set to "0".

---Setting range---

0 to 999 (rad/s)

【

#2258

】

When using SHG control during spindle synchronization control (synchronous tapping and synchronous control with spindle C-axis), set this parameter with SV049 (PGN1sp) and SV050

(PGN2sp).

Make sure to set the value 6 times that of SV049.

When not using the SHG control, set to "0".

---Setting range---

0 to 1200 (rad/s)

CAUTION

Always set the same value for the position loop gain between the spindle and servo synchronous axes.

(3) SHG control

If the position loop gain is increased or feed forward control (NC function) is used to shorten the settling time or increase the precision, the machine system may vibrate easily.

SHG control changes the position loop to a high-gain by stably compensating the servo system position loop through a delay. This allows the settling time to be reduced and a high precision to be achieved. (SHG: Smooth

High-Gain)

(Feature 1) When the SHG control is set, even if PGN1 is set to the same value as the conventional gain, the position loop gain will be doubled.

(Feature 2) The SHG control response is smoother than conventional position control during acceleration/ deceleration, so the gain can be increased further with SHG control compared to the conventional position control.

(Feature 3)With SHG control, a high gain is achieved so a high precision can be obtained during contour control.

The following drawing shows an example of the improvement in roundness characteristics with SHG control.

During SHG control even if the PGN1 setting value is the same, the actual position loop gain will be higher, so the speed loop must have a sufficient response. If the speed loop response is low, vibration or overshooting could occur during acceleration/deceleration in the same manner as conventional control. If the speed loop gain has been lowered because machine resonance occurs, lower the position loop gain and adjust.

5.2.4 OMR-FF Function

OMR-FF control improves the inner rounding amount of the arc, corner tracking error, or path vibration, etc. more comprehensively than conventional high-speed high-accuracy control by creating appropriate feed forward command for each of position, speed, and current depending on the vibration characteristics of the control target.

Feed forward is performed inside the drive unit according to the scale model and inertia setting in the OMR-FF generation part, and can independently set the command trackability with the scale model position loop gain (PGM) and the servo rigidity with the position control gain (PGN). This enables the higher and smoother trackability to the position command.

This function can be highly effective for linear servo, direct drive motors, or general motors in semi-closed loop control.

OMR-FF control option for NC side is required when using this function.

5.3 Characteristics Improvement

5.3.1 Optimal Adjustment of Cycle Time

The following items must be adjusted to adjust the cycle time. Refer to the Instruction Manuals provided with each CNC for the acceleration/deceleration pattern.

[1] Rapid traverse rate (rapid) : This will affect the maximum speed during positioning.

[2] Clamp speed (clamp) : This will affect the maximum speed during cutting.

[3] Acceleration/deceleration time constant (G0t*, G1t*) : Set the time to reach the feedrate.

[4] In-position width (SV024) : This will affect each block's movement command end time.

[5] Position loop gain (SV003) : This will affect each block's movement command settling time.

(1) Adjusting the rapid traverse

To adjust the rapid traverse, the CNC axis specification parameter rapid traverse rate (rapid) and acceleration/ deceleration time constant (G0t*) are adjusted. The rapid traverse rate is set so that the motor speed matches the machine specifications in the range below the maximum speed in the motor specifications. For the acceleration/ deceleration time constants, carry out rapid traverse reciprocation operation, and set so that the maximum current command value at acceleration/deceleration is within the range shown below. The output torque is limited at areas near the maximum speed, so monitor the current FB waveform during acceleration/deceleration and adjust so that the torque is within the specified range.

If the drive unit's input voltage is less than the rated voltage, the torque will easily become insufficient, and excessive errors will occur easily during acceleration/deceleration.

(2) Adjusting the cutting feed

To adjust the cutting rate, the NC axis specification parameter clamp speed (clamp) and acceleration/deceleration time constant (G1t*) are adjusted. The in-position width at this time must be set to the same value as actual cutting.

• Determining the clamp rate and adjusting the acceleration/deceleration time constant

(Features)The maximum cutting rate (clamp speed) can be determined freely.

(Adjustment)Carry out cutting feed reciprocation operation with dwell at the maximum cutting rate and adjust the acceleration/deceleration time constant so that the maximum current command value during acceleration/deceleration is within the range shown below.

• Setting the step acceleration/deceleration and adjusting the clamp speed

(Features)The acceleration/deceleration time constant is determined with the position loop in the servo, so the acceleration/deceleration F Δ T can be reduced.

(Adjustment)Set 1 (step) for the acceleration/deceleration time constant and carry out cutting feed reciprocation operation with dwell. Adjust the cutting feed rate so that the maximum current command value during acceleration/deceleration is within the range shown below, and then set the value in the clamp speed.

(3) Adjusting the in-position width

Because there is a response delay in the servo motor drive due to position loop control, a "settling time" is also required for the motor to actually stop after the command speed from the CNC reaches 0.

The movement command in the next block is generally started after it is confirmed that the machine has entered the

"in-position width" range set for the machine.

Set the precision required for the machine as the in-position width. If a high precision is set needlessly, the cycle time will increase due to a delay in the settling time.

The in-position width is validated with the servo parameter settings, but there may be cases when it is validated with the NC parameters. Refer to each NC Instruction Manual.

【

Set the positioning accuracy required for the machine.

The lower the setting is, the higher the positioning accuracy will be. However the cycle time (settling time) becomes longer.

(4) Adjusting the settling time

The settling time is the time required for the position droop to enter the in-position width after the feed command (F Δ T) from the CNC reaches 0.

The settling time can be shortened by raising the position loop gain or using SHG control. However, a sufficient response (sufficiently large VGN1 setting) for the speed loop is required to carry out stable control.

The settling time during normal control when the

CNC is set to linear acceleration/ deceleration can be calculated using the following equation. During

5.3.2 Vibration Suppression Measures

If vibration (machine resonance) occurs, it can be suppressed by lowering the speed loop gain 1 (VGN1). However, cutting precision and cycle time will be sacrificed. (Refer to "Speed Loop Gain".) Thus, try to maintain the VGN1 as high as possible, and suppress the vibration using the vibration suppression functions.

If the VGN1 is lowered and adjusted because vibration cannot be sufficiently suppressed with the vibration suppression functions, adjust the entire gain (including the position loop gain) again.

(Examples of vibration occurrence)

• A fine vibration is felt when the machine is touched, or a groaning sound is heard.

• Vibration or noise occurs during rapid traverse.

If machine resonance occurs, the resonance frequency can be confirmed at AFLT frequency on NC drive monitor screen. Based on this frequency, the notch filter frequency can be set. The display sensitivity can be adjusted in the

"sensitivity of estimated resonance frequency" setting. (When "0" is displayed, vibration at high frequency or vibration due to the machine system may be the reason.)

POINT

Suppress the vibration using the vibration suppression functions, and maintain the speed loop gain (SV005) as high as possible.

< Notch filter >

This servo drive unit mounts 5 notch filters. Measure the resonance frequency with AFLT frequency display on NC drive monitor screen and the current feedback analog output function, and set that frequency in parameter.

However, if the notch filter is set to a particularly low frequency, another resonance frequency that did not vibrate initially may occur. If the notch filter's depth compensation (SV033, nfd1, nfd2) is adjusted so that the filter does not operate unless necessary, the servo control will be stabilized.

Notch filter 3 is a filter with frequency fixed to 1125Hz, and has no depth compensation.

< Setting method >

[1] Set the resonance frequency in the notch filter frequency (1, 2, 4, 5).

[2] If the machine starts to vibrate at another frequency, raise (make shallower) the notch filter depth compensation value, and adjust to the optimum value at which the resonance can be eliminated.

[3] When the vibration cannot be completely eliminated, use also another notch filter for this frequency.

< Notch filter frequency adaptive tracking function >

Machine system resonance can vary depending on secular changes or installation conditions of machine, resonance frequency may deviate from the notch filter frequency set at the initial adjustment. The adaptive tracking function estimates minor changes in resonance frequency from current command oscillating component, automatically adjusting notch filter effective frequency. The resonance frequency is estimated while G0 is moving and effective frequency is modified while the axis is stopped.

The adaptive tracking function can be applied to notch filter 1, 2, 4, 5 (SV038, SV046, SV087, SV088). When resonance frequency is detected within the adaptive ranges which centers in the frequency set by parameter, resonance frequency from which notch filter effective frequency with the closest setting value is detected, suppressing machine resonance.

< Other specifications >

(a) Machine resonance is detected at frequency ranges of 150Hz to 90Hz.

(b) The depth of notch filter is not automatically adjusted. Only the effective frequency will change while the filter depth remains fixed.

(c) When the notch filter 5 is adaptive to all frequency and also, others are not available, the effective frequency of notch filter 5 is changed.

(d) When parameter setting value is changed; if the effective frequency remains within the adaptive ranges, it will keep operating with the original frequency; if it doesn't, changed parameter value will be applied.

< Jitter compensation (Vibration control when motor is stopped.) >

The load inertia becomes much smaller than usual if the motor position enters the machine backlash when the motor is stopped. Because this means that an extremely large VGN1 is set for the load inertia, vibration may occur.

Jitter compensation can suppress the vibration that occurs at the motor stop by ignoring the backlash amount of speed feedback pulses when the speed feedback polarity changes.

Increase the number of ignored pulses by one pulse at a time, and set a value at which the vibration can be suppressed. (Because the position feedback is controlled normally, there is no worry of positional deviation.)

When jitter compensation is set to an axis that is not vibrating is set, vibration could be induced, so take care.

< Variable speed loop gain control >

If vibration occurs when the motor is rotating at a high speed, such during rapid traverse, or if disturbing noise occurs, the state can be improved by lowering the speed loop gain during high-speed rotation. The low-speed region speed loop gain used for cutting feed (G1 feed), etc., is maintained at a high level, so the vibration can be improved without dropping the machining accuracy.

【

#2205

】

Set the speed loop gain.

The higher the setting value is, the more accurate the control will be, however, vibration tends to occur.

If vibration occurs, adjust by lowering by 20 to 30%.

The value should be determined to the 70 to 80% of the value at which the vibration stops.

The value differs depending on servo motors.

5.3.3 Improving the Cutting Surface Precision

If the cutting surface precision or roundness is poor, these can be improved by increasing the speed loop gain (VGN1,

VIA) or by using the disturbance observer function.

Y

X

< Examples of faults >

• The surface precision in the 45° direction of a taper or arc is poor.

• The load fluctuation during cutting is large, causing vibration or surface precision defects to occur.

POINT

Adjust by raising the speed loop gain equivalently to improve cutting surface precision, even if the measures differ. In this case, it is important how much the machine resonance can be controlled, so adjust making sufficient use of vibration suppression functions.

(1) Adjusting the speed loop gain (VGN1)

If the speed loop gain is increased, the cutting surface precision will be improved but the machine will resonate easily.

The final VGN1 setting should be approx. 70 to 80% of the maximum value where resonance does not occur.

(Refer to "Setting the speed loop gain")

(2) Adjusting the speed loop leading compensation (VIA)

The VIA has a large influence on the position trackability, particularly during high-speed cutting (generally F1000 or more). Raising the setting value improves the position trackability, and the contour precision during high-speed cutting can be improved. For high-speed high-precision cutting machines, adjust so that a value equal to or higher than the standard value can be set.

When VIA is set lower than the standard value and set to a value differing between interpolation axes, the roundness may worsen (the circle may distort). This is due to differences occurring in the position trackability between interpolation axes. The distortion can be improved by matching the VIA with the smaller of the values. Note that because the position trackability is not improved, the surface precision will not be improved.

(3) Voltage non-sensitive zone (Td) compensation

With the PWM control of the inverter circuit, a dead time (non-energized time) is set to prevent short-circuits caused by simultaneous energizing of the P side and N side transistors having the same phase. The dead time has a nonsensitive zone for particularly low voltage commands. Thus, when feeding with a low speed and a low torque, the control may be unstable.

When an unbalanced axis is lowering, the frictional torque and unbalance torque, and the frictional torque and deceleration torque before the quadrant changes during circle cutting, are balanced. The motor output torque will be approximately zero, and the control accuracy may drop. In this case, the control accuracy can be improved by using the voltage non-sensitive band compensation. Note that this may cause vibration to be increased while the motor is running.

< Acceleration feed forward >

Vibration may occur at 10 to 20 Hz during acceleration/deceleration when a short time constant of 30 ms or less is applied, and a position loop gain (PGN1) higher than the general standard value or SHG control is used. This is because the torque is insufficient when starting or when starting deceleration, and can be resolved by setting the acceleration rate feed forward gain (SV015: FFC). This is also effective in reducing the peak current (torque).

While measuring the current command waveform, increase FFC by 50 to 100 at a time and set the value where vibration does not occur.

Acceleration rate feed forward gain means that the speed loop gain during acceleration/deceleration is raised equivalently. Thus, the torque (current command) required during acceleration/deceleration starts sooner. The synchronization precision will improve if the FFC of the delayed side axis is raised between axes for which highprecision synchronous control (such as synchronous tapping control and superimposition control).

When a relative error in synchronous control is too large, set this parameter to the axis that is delaying.

The current loop response is improved by compensating the back electromotive force element induced by the motor rotation. This improved the current command efficiency, and allows the acceleration/deceleration time constant to the shortened.

< HAS control >

If an output torque during acceleration/deceleration is close to the servo motor's maximum torque, the motor cannot accelerate with a commanded time constant when the torque is saturated due to input voltage fluctuation, etc.

Generally, if an acceleration command is switched to a constant speed command, speed FB overshoots to compensate a delay of position droop, making the machine operation unstable.

When the HAS control is enabled, a delay of position droop will be compensated by controlling the amount of speed

FB overshoot within 1% or less than maximum speed of the motor.

The controllable amount of position droop delay with HAS control HAS can be set at 1/4 or 1/2 of the excessive error detection width.

2. HAS control can not be used for axes in synchronous control since machine torsion may be occur.

3. Even if HAS control is enabled, adjust the acceleration/deceleration time constant so that the current limit does not occur.

5.3.5 Improvement of Protrusion at Quadrant Changeover

The response delay (caused by dead band from friction, torsion, expansion/contraction, backlash, etc.) caused when the machine advance direction reverses is compensated with the lost motion compensation (LMC compensation) function.

With this, the protrusions that occur at the quadrant changeover in the DBB measurement method, or the streaks that occur when the quadrant changes during circular cutting can be improved.

[1] LMC compensation type 2

This is an obsolete compensation method. When performing new adjustment, use LMC compensation type 3.

[2] LMC compensation type 3

In addition to frictional torque influence, this type compensates torsion and expansion/contraction influences in the machine system in which compensation amount is changed by travel speed. A mechanical system viscosity coefficient setting further enhances the compensation accuracy even if the travel speed is changed. Adjustment requires a machine roundness measurement.

[3] LMC compensation type 4

This is used in combination with LMC compensation type 3. Compensation is performed by monitoring path tracking delay. Therefore, even if the machine friction amount has changed due to aged deterioration, the path tracking delay is controlled so that it will be minimum.

POINT

1. LMC compensation performs adjustment while measuring the electrical end roundness waveform (encoder position FB).

Disable the NC side machine error compensation (pitch error compensation, relative position compensation, backlash compensation). All machine error compensation can be disabled at once by setting bit7 of SV113 to 1.

2. After the compensation adjustment is completed, adjust the machine error compensation while measuring the machine error compensation with DBB measurement method, etc.

(1) Measuring unbalance torque and frictional torque

Machine unbalance torque and frictional torque measurements are required before the LMC compensation can be set. However, the horizontal axis unbalance torque is necessarily "0".

Carry out the reciprocating operation (approx. F1000) with the measured axis, and the load current % value during constant-speed feed is measured at the NC servo monitor screen. The unbalance torque and frictional torque at that time are expressed by the following formulas.

Unbalance torque (%) =

(+ feed load current %) + (- feed load current %)

2

Frictional torque (%) =

| (+ feed load current %) - (- feed load current %) |

2

(Example)

Assume that the load current % was -55% in the + direction and -25% in the - direction when JOG feed was carried out at approx. F1000. The unbalance torque and frictional torque are as shown below.

Unbalance torque (%) =

(-55) + (-25)

2

= -40%

Friction torque (%) =

(-55) - (-25)

2

= 15%

The measurement values are not used for LMC compensation type 3. However, since they are used for other controls, set them to the following parameters.

【

#2232

】

Set the unbalance torque on vertical axis and inclined axis.

When the vertical axis pull up function is enabled, the pull up compensation direction is determined by this parameter's sign. When set to "0", and the pull up function is enabled (SV033/bitE=1), the alarm "S02 2233 Initial parameter error" occurs.

This can be used for speed loop delay compensation and collision detection function.

To use load inertia estimation function (drive monitor display), set this parameter, friction torque

(2) Setting and adjusting LMC compensation type 3

LCM compensation type 3 can be used to accommodate quadrant projection changes that accompany feed rate and circular radius changes which could not be accommodated by LCM compensation type 2. In this case, on a machine model where the travel direction is reversed, the effect caused by torsion or expansion and contraction on the machine system are also considered in addition to the friction, with compensation occurring in accordance with the changes in the cutting conditions.

Adjust Compensation parameter (SV016, SV041), a basis of compensation, while measuring roundness at low speed. Then adjust viscous coefficient (SV086) while measuring roundness at high speed.

LMC compensation type 3 parameter adjustments should be made while measuring an electrical end position FB waveform by the NC sampling function.

< Adjustment method >

[1] Turn the NC side machine error compensation (pitch error compensation, relative position compensation or backlash compensation) OFF.

[2] Set servo function selection 5 SV082/ bit=1. (The LMC compensation type 3 will start).

[3] Set a value double the friction torque to the lost motion compensation 1 (SV016). The SV016 setting value will be used for compensation in the positive and negative directions when the lost motion compensation 2

(SV041) is 0.

[4] Set the initial value, SV016 x 200 to the lost motion compensation viscous coefficient (SV086).

[5] Perform a roundness measurement at such speed as radius R=100mm and feedrate F=1000mm/min and adjust SV016 value.

[6] Set SV041, when changing the compensation amount in the direction for compensation. The setting of the compensation direction is shown below with the setting of CW/CCW in the NC parameter. If compensating only one direction, set –1 to the side not to be compensated.

[7] Perform a roundness measurement at such speed as radius, R=100mm and feedrate, F=5000mm/min. (Select a condition to be used for the actual cutting according to the machine's specification.) Adjust viscous coefficient (SV086) by increasing and reducing it approx. ±500 gradually to have minimum quadrant protrusion.

[8] After adjusting SV086, verify its accuracy by performing roundness measurement at low speed again.

[9] At this time, if requiring to improve the accuracy further, adjust the spring constant (SV085) in increments of about 50 while performing the machine roundness measurement at low speed.

POINT

1. As the acceleration of circular feed increases, the quadrant protrusion tends to get larger. Therefore, the quadrant protrusion gets larger as the circular feedrate increases for the same radius and as radius gets smaller for the same feedrate.

2. Torque offset (SV032) does not work for LMC compensation type 3.

3. Always set 0 to the lost motion compensation timing (SV039:LMCD).

Set this parameter when the protrusion (that occurs due to the non-sensitive band by friction, torsion, backlash, etc.) at quadrant change is too large. This sets the compensation torque at quadrant change (when an axis feed direction is reversed) by the proportion (%) to the stall torque. Whether to enable the lost motion compensation and the method can be set with other parameters.

Type 2: When SV027/bit9, 8 =10 (Compatible with obsolete type)

Set the type 2 method compensation torque. The standard setting is double the friction torque.

Type 3: When SV082/bit1= 1

Set the compensation torque equivalent of dynamic friction amount of the type 3 method compensation amount. The standard setting is double the dynamic friction torque.

To vary compensation amount according to the direction.

When SV041 (LMC2) is "0", compensate with the value of SV016 (LMC1) in both +/-directions.

If you wish to change the compensation amount depending on the command direction, set this and SV041 (LMC2).

(SV016: + direction, SV041: - direction. However, the directions may be opposite depending on other settings.)

When "-1" is set, the compensation will not be performed in the direction of the command.

(3) Setting and adjusting LMC compensation type 4

LMC compensation type 4 is enabled by being used with LMC compensation type 3. Make sure to adjust the LMC compensation type 3 before setting the LMC compensation type 4.

< Adjustment method >

[1] Set about 5-fold SV016 setting value in SV091. (Set about 10% of machine friction.)

[2] Increase SV0091 in increments of about 20%, and confirm the limit value where vibration does not occur. Note that the limit value is about 500.

[3] Set 50% of the limit value.

【

Use this with LMC compensation type 3. As the delay in path tracking is monitored and compensated, the delay in path tracking will be minimized even if machine friction amount changes by aging.

The higher the setting value is, the more accurate the quadrant change be; however, the more likely vibrations occur.

5.3.6 Improvement of Overshooting

The phenomenon when the machine position goes past or exceeds the command during feed stopping is called overshooting. Overshooting is compensated by overshooting compensation (OVS compensation). Overshooting occurs due to the following two causes.

[1] Machine system torsion: Overshooting will occur mainly during rapid traverse settling.

[2] Machine system friction: Overshooting will occur mainly during one pulse feed.

Either phenomenon can be confirmed by measuring the position droop.

5 Servo Adjustment

(1) Overshooting compensation (OVS compensation)

In OVS compensation, the overshooting is suppressed by subtracting the torque command set in the parameters when the motor stops.

OVS compensation type 3 has a compensation effect for the overshooting during either rapid traverse settling or pulse feed. To compensate overshooting during feed forward control, refer to the following section "(2) Adjusting for feed forward control".

< Setting and adjustment methods >

[1] Set the servo function selection 1 (SV027: SSF1)/bit A, B. (OVS compensation type 3 will start.)

[2] Observe the position droop waveform using the D/A output, and increase the overshooting compensation 1

(SV031: OVS1) value 1% at a time. Set the smallest value where the overshooting does not occur. If SV042

(OVS2) is 0, the overshooting will be compensated in both the forward/reverse directions with the OVS1 setting value.

[3] If the compensation amount is to be changed in the direction to be compensated, set the + direction compensation value in OVS1 and the - direction compensation value in OVS2. If only one direction is to be compensated, set the side not to be compensated as -1. The compensation direction setting will be as reversed with the NC parameter CW/CCW setting.

POINT

1. When either parameter SV031: OVS1 or SV042: OVS2 is set to 0, the same amount of compensation is carried out in both the positive and negative direction, using the setting value of the other parameter (the parameter not set to 0).

2. To compensate in only one direction, set -1 in the parameter (OVS1 or OVS2) for the direction in which compensation is prohibited.

3. For contour cutting, the projection at the arc end point is compensated with OVS compensation. LMC compensation is carried out at the arc starting point.

OVS compensation LMC compensation

Cutting direction

(2) Adjusting for feed forward control

When using feed forward control (high-speed high-accuracy control), the feed forward control must be stopped

(fwd_g =0) before adjusting the overshooting compensation. After adjusting the overshooting compensation with normal control, set the overshooting compensation non-sensitive zone (SV034 (SSF3)/bitC to F (ovsn) to 1 (2µm) and start up feed forward control.

If overshooting compensation is used during feed forward control, the overshooting will increase, or protrusions could appear during arc cutting. This is because, when the NC is carrying out feed forward (fwd) control, overshooting equivalent to the operation fraction unit occurs in the position command, and the OVS compensation is recognized as a change in the command direction, resulting in compensation in the reverse direction. This can be improved by setting the overshooting compensation non-sensitive zone width.

If overshooting does not occur during normal control, and occurs only during feed forward control, adjust the feed forward gain (fwd_g).

5.3.7 Improvement of the Interpolation Control Path

(1) Machine end compensation control

The machine end compensation control compensates the shape of the tool end during high-speed and high-speed acceleration/deceleration. The spring effect from the machine (spindle) end to the motor (scale) end is compensated. If the machine has a large spring effect, the shape may be fine during low-speed operation.

However, at high speeds (specially when using a small radius), the section from the machine (spindle) end to the outer sides of the motor (scale) end could swell, and cause the shape to become elliptical during measurement of the roundness. The machine end compensation control compensates the motor end position according to the acceleration size, so the tool end position is always controlled to the commanded position.

The inner side is driven by the amount that the end section swells due to the spring effect.

During high acceleration, the end section swells outward due to the spring effect.

5.4 Adjustment during Full Closed Loop Control

5.4.1 Outline

(1) Full closed loop control

The servo control is all closed loop control using the encoder's feedback. "Full closed loop control" is the system that directly detects the machine position using a linear scale, whereas the general "semi-closed loop" is the one that detects the motor position.

In a machine that drives a table with a ball screw, the following factors exist between the motor and table end:

[1] Coupling or ball screw table bracket's backlash

[2] Ball screw pitch error

These can adversely affect the accuracy. If the table position is directly detected with a linear scale, high-accuracy position control which is not affected by backlash or pitch error is possible. However, with the full closed loop system, the machine system is also directly included in the position loop control. Thus, if the machine's rigidity is not high, the gain cannot be increased, and the required high accuracy cannot be attained.

The procedures for adjusting the servo with the full closed loop system are the same as the semi-closed loop system. Vibration or overshooting will occur easily, so the position loop gain is generally lower than the semi-closed loop.

(2) Overrun detection

With the full closed system, the position feedback (FB) detected with the linear scale is used for the position control.

However, the motor position FB is detected at the same time, and the error of both FB is observed. If this FB error exceeds the servo parameter SV054 setting value, alarm 43 will be detected and the system will stop to prevent overrunning due to a scale FB error from occurring.

Set the overrun detection width in the full-closed loop control.

When the gap between the motor side encoder and the linear scale (machine side encoder) exceeds the value set by this parameter, it will be judged as overrun and "Alarm 43" will be detected.

When "-1" is set, if the differential velocity between the motor side encoder and the machine side encoder exceeds the 30% of the maximum motor speed, it will be judged as overrun and "Alarm 43" will be detected.

When "0" is set, overrun will be detected with a 2mm width.

5 Servo Adjustment

5.4.2 Speed Loop Delay Compensation

Generally, the machine position follows the operation later than the motor position. With full closed loop position loop control, the machine position is used for position feedback, so the motor position could advance too far and cause the machine position to overshoot easily. Speed loop delay compensation suppresses overshooting by weakening the speed loop PI control (weakening lead compensation = delaying). If the compensation is too large and PI control is weakened too far, the positioning time could increase, or the position droop will remain when the motor is stopped.

< Adjustment method >

[1] Set the servo function selection 1 (SV027: SSF1)/bit1, bit0 to 10. (Select delay compensation changeover type

2)

[2] Set the axis unbalance torque to the torque offset (SV032: TOF). (Refer to "Measuring unbalance torque and frictional torque" for details on measuring the unbalance torque.)

[3] Observe the position droop waveform, and confirm the overshooting. Increase SV007 (VIL) in increments of 5, and adjust so that the overshooting is improved. If set too high, the position droop will remain when the axis is stopped.

Set this when the limit cycle occurs in the full-closed loop, or overshooting occurs in positioning.

The speed loop delay compensation method can be selected with SV027/bit1,0.

Normally, use "Changeover type 2". Changeover type 2 controls the occurrence of overshooting by lowering the speed loop lead compensation after the position droop gets 0.

5.4.3 Dual Feedback Control

If the motor and machine coupling or machine system's rigidity is low (ex. large machine, etc.) when using a closed loop system, the response during acceleration/deceleration will vibrate and cause overshooting. This can cause the position loop gain from increasing. The dual feedback function is effective in this case.

To validate the dual feedback function, use position feedback with a motor side encoder in ranges with high acceleration to enable stable control. In ranges with low acceleration, use position feedback with the machine side encoder (scale).

This will make it possible to increase the position loop gain.

Dual feedback control

The state will approach the semi-closed loop system as the primary delay filter's time constant increases, so the position loop gain limit will increase. Note that the limit of the position loop gain increased with the dual feedback function is the same as the position loop gain limit for a semi-closed system that does not use a machine side encoder (scale, etc.). In addition, the positioning time will increase as the primary delay filter time constant increases.

POINT

1. Dual feedback control is a function that compensates symptoms resulting from insufficient machine rigidity.

If there are items that can be improved on the machine (improvement of scale installation position, etc.) improve those first.

2. The position loop gain limit will not increase compared to the semi-closed loop system even when using dual feedback control.

5.4.4 Full-closed Torsion Compensation Function

This function performs compensation by setting the torsion compensation amount based on the distance between the motor-end position and the machine-end position when the direction is reversed. Setting the torsion compensation amount in addition to the conventional lost motion compensation enables to reduce the distance from the machine end and smooth the tracking to the position command. When "SV116/bit1" is set to "1", compensation is performed not only in the reverse direction but also in the forward direction. Compensation in the forward direction performs the starting torque compensation by restoring the torsion compensation amount based on the distance between the motor-end position and the machine-end position when stopped.

5.5 Settings for Emergency Stop

Emergency stop in this section refers to the following states.

[1] Emergency stop was input (including other axis alarms)

[2] NC power down was detected

[3] A drive unit alarm was detected

5.5.1 Deceleration Control

With the servo drive unit, if the deceleration stop function is validated, the motor will decelerate following the set time constant while maintaining the READY ON state. READY will turn OFF and the dynamic brakes will function after stopping.

If an alarm, for which dynamic brakes are designated as the stopping method, occurs, the motor will stop with the dynamic brakes.

< Features >

When the load inertia is large, deceleration stop can be executed at a shorter time than the dynamic brakes.

(The stop time for the normal acceleration/deceleration time constants will be achieved.)

(1) Setting the deceleration control time constant

Set the time for stopping from the rapid traverse rate (rapid: axis specification parameter) in the deceleration time constant for emergency stop (SV056: EMGt). The operation stops with the position loop step when 0 is set.

For the standard setting value of SV056, refer to the following table.

When applying this setting to the synchronous control axes, set the same value with negative symbol to the both axes. Even if the dynamic break stop is applied to either axis, it is also applied to the other axis.

POINT

1. Deceleration control will not take place when a servo alarm, for which the stopping method is dynamic, occurs.

The motor will stop with dynamic braking regardless of the parameter setting.

2. If the power fails and the deceleration time constant is set to a relatively long time, the braking method may change from deceleration control to dynamic braking due to a drop in the bus voltage in the drive unit.

CAUTION

If the deceleration control time constant (EMGt) is set to a value longer than the acceleration/deceleration time constant, the soft limit point (stroke end point) may be exceeded.

Take care as the axis could collide the machine.

5.5.2 Vertical Axis Drop Prevention Control

The vertical axis drop prevention control is a function that prevents the vertical axis from dropping due to a delay in the brake operation when an emergency stop occurs. The no-control time until the brakes activate can be eliminated by delaying the servo READY OFF state by the time set in the parameters when an emergency stop occurs.

Always use this function together with deceleration control.

< Setting procedures >

[1] Apply emergency stop while viewing the current position on the NC screen. Adjust the vertical axis drop prevention time (SV048), and set the 1.5-fold minimum delay time at which the axis does not drop.

When using a motor with a break, confirm that the axis will not drop at the 150ms setting, and set 200ms.

[2] Set the value of the normal acceleration/deceleration time constant plus 100ms for the max. gate off delay time at emergency stop (SV055), and set the standard setting value of the axis for the deceleration control time constant at emergency stop (SV056). Refer to "Deceleration Control" for details.

[3] For the axis for which the vertical drop is to be controlled, set the same value as the acceleration/deceleration time constant for the deceleration control time constant at emergency stop (SV056).

[4] If the vertical axis is MDS-E/EH-V2/V3 (2-axis or 3-axis drive unit), set the servo parameters for the other axis in the same unit.

SV048 = Same value as adjusted vertical axis SV048

SV055 = Same value as adjusted vertical axis SV055

SV056 = Standard setting value of SV055 for the axis (Refer to "Deceleration control" for details.)

[5] If the power supply unit that supplies PN power to the vertical axis is controlled by a spindle drive unit, set the time for the spindle to stop from the maximum speed to the parameters SP055 and SP056.

[6] If the power supply unit that supplies PN power to the vertical axis is controlled by a different servo drive unit, set the servo parameter setting for that axis as well. (Same as item [4] above).

[7] If the CN9 connector of the power supply unit that supplies PN power is connected with the vertical axis, also set the parameter for the drive unit connected with the CN4 connector of the same power supply unit.

3. In the 2nd part system of the power supply, if the axis for vertical axis drop prevention is connected with the CN9 connector of the power supply unit, provide the vertical axis drop prevention control setting also for the drive unit connected with CN4 connector of the same power supply unit.

4. If an alarm, for which dynamic brake stopping is designated, occurs with the axis for which vertical axis drop prevention control is active, the function will not activate. To prevent axis dropping under all conditions, provide measures on the machine side by installing a balance unit, etc.

5. In consideration of the relay delay time for the break control, set the vertical axis drop prevention time.

POINT

1. SV048 and SV055 are set for each axis, but when using MDS-E/EH-V2/V3 (2-axis or 3-axis drive unit), the axes are controlled with the larger setting value.

2. If an alarm, for which dynamic brake stopping is designated, occurs with the axis for which vertical axis drop prevention control is active, the function will not activate.

3. A drop amount of several µm to several 10µm may be generated due to brake play.

CAUTION

1. Do not set the vertical axis drop prevention time longer than required. The servo control and brakes could collide, resulting in an overload alarm or drive unit damage. There is no problem if the overlapping time is within 100ms.

2. Vertical axis drop prevention control (including deceleration control) longer than 100ms will not be guaranteed during a power failure. The operation will change to dynamic brakes.

3. If only SV048 and SV055 are set, and SV056 is set to 0, the deceleration stop will be a stepped stop and could result in collision with the machine.

5.5.3 Vertical Axis Pull-up Control

Even when the vertical axis drop prevention control is applied, the axis will drop several μ m due to the mechanical play of the motor brakes. Work could be damaged especially when the power fails during machining. For the vertical machining center, etc., vertical axis pull-up control protect works from collision by slightly pulling the vertical axis when an emergency stop (including the power failure) occurs.

If the pull-up control itself has possibility to cause interference during synchronous tapping machining or soft limit's stop, vertical axis pull-up control suppression command (servo control input 4/bit2) is input from NC and stops the pull-up control.

< Adjustment procedure >

[1] Set "Vertical Axis Drop Prevention Control".

[2] Set servo function selection 2 SV033/bitE = 1 (Vertical axis drop prevention control will start).

[3] Set the torque offset SV032. The pull-up directions is distinguished by this setting value's sign.

Refer to "Measuring unbalance torque and frictional torque measurement" for details on the setting.

[4] Input emergency stop when axes stop and confirm the subject axis to be retracted upward.

[5] If the pull-up range is insufficient, adjust vertical axis pull-up distance SV095.

2. When the power fails, charging energy remaining in the power supply unit executes the pull-up control. Thus, pull-up range depends on charging situation of the power supply or the timing when the magnetic brake is applied.

【

】

Set the unbalance torque on vertical axis and inclined axis.

When the vertical axis pull up function is enabled, the pull up compensation direction is determined by this parameter's sign. When set to "0", and the pull up function is enabled (SV033/bitE=1), the alarm "S02 2233 Initial parameter error" occurs.

This can be used for speed loop delay compensation and collision detection function.

To use load inertia estimation function (drive monitor display), set this parameter, friction torque

(SV045) and load inertia display enabling flag(SV035/bitF).

5.6 Protective Functions

5.6.1 Overload Detection

The servo drive unit is equipped with an electronic thermal that protects the servo motor and servo drive unit from overload conditions. The overload 1 alarm (alarm 50) is detected if an overload condition occurs, and the overload 2 alarm (alarm 51) is detected if 95% or more of the maximum current is commanded continuously for 1 second or longer due to a machine collision, etc. The parameters shown below are for Mitsubishi Electric adjustment purposes only, and should be kept at their standard settings (SV021=60, SV022=150).

For details concerning the overload protection characteristics, refer to the MDS-E/EH Series Specifications

Manual (IB-1501226).

5.6.2 Excessive Error Detection

An excessive error (alarms 52, 53, 54) is detected when the difference between the servo's commanded position and the

FB position exceeds the value set by parameter. Separate excessive error detection width can be set for servo ON

(SV023) and servo OFF (SV026) statuses. When a wider excessive error detection width than that used for standard control is required in stopper control, etc., the detection width setting can be changed to the SV053 setting value by NC command.

Follow-up control (NC commanded position tracks servo FB position) is used during emergency stop and during a servo

OFF command, and so there is no excessive error detection at those times, although the follow-up control during a servo

OFF status can be disabled by an NC system parameter setting.

【

Set the excessive error detection width in servo ON.

<Standard setting value>

5.6.3 Collision Detection Function

Collision detection function quickly detects a collision of the motor shaft, and decelerates and stops the motor. This suppresses the generation of an excessive torque in the machine tool, and helps to prevent an abnormal state from occurring. Impact at a collision will not be prevented by using this collision detection function, so this function does not necessarily guarantee that the machine tool will not be damaged or that the machine accuracy will be maintained after a collision. The same caution as during regular operation is required to prevent the machine from colliding.

Collision detection function outline

(a) A collision of machine is detected. (b) A retracting torque is generated.

The collision of machine is reduced.

(1) Collision detection method 1

The required torque for the command is estimated from the position command issued from the NC, and the disturbance torque is obtained from the difference with the actual torque. When this disturbance torque exceeds the collision detection level set with the parameters, the motor will decelerate to a stop with a torque 80% (standard) value of the motor's maximum torque. After decelerating to a stop, alarm 58 or 59 will occur, and the system will stop.

The collision detection level for rapid traverse (G0) is set with SV060: TLMT. The collision detection level for cutting feed (G1) is set to 0 to 7-fold (SV35.clG1) based on the collision detection level for rapid traverse. When clG1 is set to 0, collision detection method 1 will not function during cutting feed. If SV060 is set to 0, all collision detection

(including methods 1 and 2) will not function.

Thus, the same caution as during regular operation is required to prevent the machine from colliding.

MDS-E/EH Series Instruction Manual

5 Servo Adjustment

(2) Collision detection method 2

When the current command reaches the motor's maximum current, the motor will decelerate and stop at a torque

80% (standard value) of the motor's maximum torque. After decelerating to a stop, alarm 5A will occur, and the system will stop. If the acceleration/deceleration time constant is short and incorrect detections easily occur during normal operation, lengthen the acceleration/ deceleration time constant and adjust so that the current is not saturated (does not reach the maximum current) during acceleration.

If the acceleration/deceleration time constant cannot be lengthened, set parameter SV035/bitB (SSF4.c12n) to 1 to ignore collision detection method 2.

(3) Retracting torque

In each collision detection method, impact after a collision is reduced by generating the retracting torque after the collision is detected.

The retracting torque is a torque 70% to 100% which is set with SV035: SSF4/cltq (bit8, bit9) based on the current of the motor maximum ability.

POINT

1. Validate SHG control or OMR-FF function when using the collision detection function, or when carrying out SV059 setting value operation.

2. Provide an allowance in the detection level setting to prevent incorrect detections.

3. All collision detection functions will be disabled when SV60 is set to 0.

4. Collision detection method 2 will function if a value other than 0 is set in SV060. Note that the detection can be ignored by setting the parameter (SV035/bitB).

5. The torque estimated gain (SV059) must be readjusted when there are changes in the encoder replacement following maintenance, etc., in the encoder resolution, or in the position control system such as encoder loop gain (PGN), etc.

(closed loop control and semi-closed loop has been changed).

6. The retracting torque generated when a collision is detected outputs the motor maximum torque. If the torque limitation is required in order to protect the machine, set "SV035 : SSF4/cltq (bit8, bit9)".

7. Due to the steady load during machining, and changes in frictional torque and unbalance torque, collision detection method 1 is sometimes unable to accurately detect collisions. Setting "SV035 : SSF4.clof (bit3)" to 1 can improve detection accuracy for such cases.

< Setting and adjustment methods >

[1] Confirm that SHG control or OMR-FF function is enabled.

[2] Set the axis unbalanced torque to the torque offset (SV032: TOF). (Refer to "Measuring unbalance torque and frictional torque" for details on measuring the unbalance torque.)

[3] Measure the frictional torque and set in the frictional torque (SV045: TRUB). Carry out reciprocation operation

(approx. F1000) with the axis to be adjusted, and measure the load current % when the axis is fed at the constant speed on the NC SERVO MONITOR screen. This frictional torque is expressed with the following expression.

Frictional torque (%) =

(+ feed load current %) - (- feed load current %)

2

[4] Set SV035: SSF4.clt (bitF) to 1 for the axis being adjusted, and move in both directions with JOG, etc., at the rapid traverse rate. When the load inertia ratio display on the NC SERVO MONITOR screen has stabilized, set that value for the torque estimated gain (SV059: TCNV). Return SV035: SSF4.clt (bitF) to 0.

[5] To improve the detection accuracy of collision detection, set "SV035: SSF4.clof (bit3)" to 1, and enable the estimated disturbance torque offset.

[6] If the acceleration/deceleration time is short, and the current is limited, set SV035: SSF4.c12n (bitB) to 1 to invalidate collision detection method 2.

[7] Adjust the collision detection level (SV060: TLMT). First set 100. If operation at the rapid traverse rate results in an alarm, increase the setting value by approx. 20. If an alarm does not occur, lower the setting value by approx. 10. The estimated disturbance torque value on the servo monitor screen will indicate the estimated disturbance torque peak value for the latest two seconds. This value can be used as reference. Set the final setting value to a value approx. 1.5-fold the limit value at which an alarm does not occur.

[8] Divide the maximum cutting load with the value set for the collision detection level (SV060: TLMT). (Round up the decimal) Set this value in SV035: SSF4.clG1 (bitC-E).

(Example) For maximum cutting load: 200%, SV060: TLMT setting value: 80%

200/80=2.5 -> The detection level is 3 (-fold), so set SV035:SSF4 to "3xxx".

[9] Set the retracting torque when the a collision is detected to SV035: SSF4.cltq (bit8,9).

(Example) To set the retracting torque to 70% of the motor maximum torque:

Set SV035:SSF4 to "x3xx".

【

#2232

】

Set the unbalance torque on vertical axis and inclined axis.

When the vertical axis pull up function is enabled, the pull up compensation direction is determined by this parameter's sign. When set to "0", and the pull up function is enabled (SV033/bitE=1),the alarm "S02 2233 Initial parameter error" occurs.

This can be used for speed loop delay compensation and collision detection function.

To use load inertia estimation function (drive monitor display), set this parameter, friction torque

(SV045) and load inertia display enabling flag(SV035/bitF).

6.1 Adjustment Procedures for Each Control

CAUTION

1. Do not adjust when possible risks associated with adjustment procedures are not thoroughly taken into consideration.

2. Be careful when touching rotating section, or your hand may be caught in or cut.

3. Changing of parameters has to be done carefully.

6.1.1 Basic Adjustments

(1) Items to check during trial operation

[1] When the power is ON for the first time, check the wiring. When the machine is operated for the first time, check the set parameters again.

[2] Confirm that the values of the NC side parameters "slimt1 to 4", "smax1 to 4", and "smini" comply with the machine specification.

[3] When the machine running-in has not been completed, gradually raise the rotation speed (in increments of

1000r/min) for the spindle. Raise the speed at the timing when the load meter value is stabilized during rotation.

If the load meter value is higher than the normal value, stop the operation and check the spindle section of the machine.

[4] Confirm that the command (S command) speed and actual speed match during running-in. When gear ratio is set, the spindle end speed and motor speed differ.

[5] Confirm that there is no abnormal noise, odor or motor overheat during running-in.

(2) Adjusting the spindle rotation speed

When the spindle motor and the spindle end are coupled using a gear or pulley, the rotation speeds of the spindle motor and the spindle end may not match. Adjust the command and the rotation speed of spindle end with the following method.

Apply the following adjustment methods [1] to [3] individually to each of the gears 00 to 11. Confirm that the machine's gear changes correctly before the adjustment.

[1] Set the spindle specification parameters, "slimt1 to 4".

Calculation expression: slimt1 to 4 = SP026 × (deceleration rate of the gears 00 to 11 between the motor and spindle end)

[2] Set the S command to half of the maximum spindle rotation speed and confirm the rotation speed of the spindle end. Adjust slimt1 to 4 until the rotation speed matches.

[3] Set the S command to the maximum spindle end rotation speed and confirm that the S command speed and the spindle end speed match.

6.1.3 Adjusting the Acceleration/Deceleration Operation

(1) Calculating the theoretical acceleration/deceleration time

The spindle motor output characteristics (shown on the right) have three ranges, which are constant torque, constant output, and deceleration ranges. Each range has different calculation method. The acceleration/ deceleration time is calculated using the calculation expression which corresponds to each range of the rotation speed for calculation. Note that the load torque (friction torque) is not considered in the calculation expression, so the result may slightly differ from the actual acceleration/ deceleration time.

(a) Maximum motor output during acceleration/deceleration: Po

The output during acceleration/deceleration (actual acceleration/

Output characteristics for acceleration/deceleration deceleration output) Po is 1.2-fold of "Standard output during acceleration/deceleration" or "Short time rated output".

The output Po during acceleration/deceleration follows the expression below.

Po = ( "Short time rated output" or "Standard output during acceleration/deceleration" ) x 1.2

Substitute this value into Po of the expression.

(b) Total load inertia: J all

Total load inertia means the total inertia of the spindle motor and of the components which are rotated the motor (shaft, etc.).

J all

= (Motor inertia) + (Spindle conversion inertia) [kg•m

The values obtained in (a) and (b) are substituted into the following calculation expressions.

To calculate the acceleration/deceleration time of the rotation speed N (r/min), use the expression (c), (d) or

(e) which is selected depending on the range that corresponds to the speed N.

Ex.) When "GD

2. If the AC input power voltage to the power supply is low, or if the input power impedance is high, the acceleration/ deceleration time may be long. (Especially, the acceleration/deceleration time of the deceleration output range may be long.)

3. For the actual measurement in comparison with the theoretical value, perform under the same condition as the calculated load inertia of Jall. The acceleration/deceleration time differs according to the inertia. When performing the measurement with a workpiece or tool installed to the spindle, confirm that the acceleration/deceleration time has been calculated when the total inertia is included in the installed workpiece and tool.

(2) Measuring the acceleration/deceleration waveforms

Measure the speed feedback and current feedback output by setting the monitor output data on "Time-series data measurement" with NC Analyzer, and check if theoretical acceleration/deceleration time is within ±15%. Refer to

"NC Analyzer Instruction Manual (IB-1501086)" for details on setting the monitor output data.

Acceleration time:ta

Deceleration time:td

Measure the time from current rise to current fall.

Acceleration/deceleration characteristics of spindle motor

When acceleration/deceleration time does not match the theoretical value (an error rate 15% or more), check the following items.

[1] There may be an error in calculating load inertia for the motor axis conversion used when calculating the theoretical acceleration/deceleration time. Check the load inertia again.

[2] When acceleration time is long and deceleration time is short, friction torque is thought to be large. Check load meter value at the maximum speed (spindle monitor screen). If the load is 10% or more, friction torque is thought to be relatively large. Mechanical friction, such as bearing friction or timing belt friction, is assumed to be large. Measure the acceleration/deceleration time again following trial run.

[3] Even if the problems above are not found, when acceleration/deceleration time does not match, there may be a possibility of using spindle motor and spindle drive unit that are not specified, or using wrong parameters.

Check the spindle motor type and spindle drive unit type again, as well as the spindle parameter settings.

POINT

There are cases where acceleration/deceleration waveforms change depending on the spindle temperature.

Check the waveforms when the spindle temperature is high (after continuous operation) and when it is low.

CAUTION

Vibration or sudden acceleration/deceleration may occur during adjustment. When performing measurement with a workpiece or tool installed, pay careful attention for the safety during adjustment.

(3) Adjustment when the load inertia is large

When the load inertia is large and acceleration time is 10s or more, excessive speed deviation alarm (ALM23) may occur because the time in which deviation between speed command and speed FB, which is the actual spindle motor rotation speed, exists is prolonged. In this case, increase the time constant (3101 to 3104) during spindle rotation by S command. When the acceleration time is 10s or less, use the standard value 300 (300ms).

Alarm can be avoided by adjusting excessive speed deviation timer (SP117). However, in this case, alarm detection will be delayed during constant speed operation.

(2) Confirmation in orientation stop at deceleration ≒ 0 rotation according to spindle specification

If orientation stop is performed with the load inertia increased due to an excessive workpiece or tool installed to the spindle, the spindle may start vibrating by trying to reverse after overshooting the stop position and stop after converging the vibrations (refer to the waveform below).

In this case, the orientation completion time is extended by the time to converge the spindle vibrations. Thus, the adjustment to suppress the reversing and vibrations at stop is required.

< Adjustment method >

1) Set SP016: Lower the setting value by 5. By lowering, the inclination of the speed becomes gradual. Set the optimum value while observing the speed waveform so that the speed will not vibrate.

2) Lower the position loop gain.

By lowering the position loop gain, a sway that exceeds the stop position is suppressed.

3) Adjust the speed gain (SP005, SP006).

The converging time becomes shorter if the rigidity during orientation stop is higher. However this affects the speed stability during constant feed, thus it is required to confirm the speed waveform at the constant speed and the machining surface during cutting.

6.1.6 High-speed Synchronous Tapping

This function uses high-speed communication between drive units to send compensation data from a spindle to a servo system. The servo system uses the received data for compensation to follow the spindle position, and reduce synchronous errors. This function can also suppress speed overshoot in cases of acceleration/deceleration at time constants that may reach the spindle torque limit. As such, shorter time constants can be set compared to the conventional normal synchronous tapping, and cycle times can be reduced. However, high-speed synchronous tapping function does not guarantee higher machining accuracy than normal synchronous tapping.

When performing high-speed synchronous tapping control(#1281/bit5), set the reduction rate of the time constant compared to the time constant in normal synchronous tapping.

(Setting "0" or "100" will be regarded as reduction rate zero, so the time constant won't be reduced.)

---Setting range---

(Note) The inclination of linear acceleration/deceleration control for multi-step synchronous tapping is determined by the ratio of "rotation speed" to "acceleration/deceleration time constant". When using multi-step synchronous tapping, the inclination should be set so that the 1st step is higher than the second step, and the second step is higher than the third step. When the inclination of the latter step is higher, the multi-step setting is disabled and the inclination of the former step is applied.

[3] The checking of error waveforms

Check the error waveforms of the time constant to be set to confirm that the synchronous errors are less than or equal to the base value.

Disable machine end compensation such as backlash compensation before checking.

Base value

The base value of synchronous errors is 8.8° or less during M6 and PIT1 machining.

(The conventional base value of 100 pulses or less is based on 4096 pulses per rotation, therefore

-

100 [pulse]/4096 [pulse] × 360 [°] ≒ 8.8 [°])

As shown in the figure below, a synchronous error may become larger due to lost motion of a servo axis etc. when starting tapping or during velocity reversal at the hole bottom. At the start, the work is not within cutting range so it will not be affected. When this error is large, adjust the servo axes with lost motion compensation etc.

The work is not within cutting range so it will not be affected.

When torque saturation is released, synchronous errors may become larger. There is no problem if the synchronous error is the same or smaller than the base value. If the error is large, it can be improved by increasing the time constant or lowering the synchronous tapping position gain of the spindle.

6.1.9 Deceleration Coil Changeover Valid Function by Emergency Stop

If a large workpiece is mounted on a large workpiece chuck in lathe, the acceleration/deceleration time increases because of the increase of the total inertia. When the deceleration stop time at emergency stop exceeds the upper limit value (29900ms) of the gate shutoff delay time (SP055), the spindle motor will coast.

This function enables the coil changeover motor to change to low-speed coil during emergency stop and if the deceleration time is reduced to complete within the gate shutoff time, the spindle enters an emergency stop state.

6.1.11 Spindle Cutting Withstand Level Improvement

Conventionally, the spindle rotation speed was slowed down due to heavy cutting that exceeds the spindle output characteristics, and this caused the alarm (Excessive error 52, Overload command 51) to stop the machining.

This function enables setting of the dropping speed allowable value by parameter. As long as the speed is the set value or higher, machining can be executed within the output characteristics without being stopped by the alarm.

Even when the parameter setting value is the normal value of 0, the standard value of 85 is applied. This can improve the efficiency of heavy cutting (feed per revolution).

If excessive speed dropping occurs and the speed exceeds the allowable range, the excessive speed deviation alarm 23 is output to reduce the damage to the machine.

Spindle

When the spindle speed is lowered by machining which exceeds the maximum torque, the feed axis speed is also lowered.

When the spindle slows down due to multiple cutting, set the processable speed as percentage against the NC command speed.

If the speed reduces below the tolerable range, the alarm 23 (Excessive speed error) will occur.

If S1000 is commanded, the speed reduced by 900r/min (=1000r/min × 90%) is the allowable

lower limit. Thus if the spindle speed reduces to 100r/min or below, the alarm will occur.

6.1.12 Spindle Motor Temperature Compensation Function

When an IM spindle motor is in a cooled state, its maximum output characteristics tend to degrade compared to when warmed up. Eventually the spindle acceleration deceleration time may extend or the cutting load on the display may increase immediately after the start of operation.

This function is designed to reduce the motor output degradation caused by the temperature fluctuation, by applying control compensation according to the temperature detected by the motor's built-in thermistor.

For an IPM spindle motor, changes in output characteristics induced by the temperature fluctuation can be ignored in principle, so no thermal compensation function is provided for this type of motor.

then turn the NC power OFF and ON.

[2] Rotate the spindle at the command speed of 60r/min.

[3] Make sure that [Cycle counter] on the spindle monitor screen is counting up or down.

[4] Stop the spindle (M5 stop: servo OFF).

[5] Create a program that repeats acceleration/deceleration up to the maximum rotation speed in constant output.

* If the machine’s specified speed is lower than the motor’s maximum speed in constant output,

set the machine specification as the maximum rotation speed.

[6] Set SP226 bit8 to 1. (Change SP226(SFNC6) from 0000 to 0100.)

[7] Run the program (acceleration/deceleration) which you created in [5].

[8] Make sure that [AFLT gain (dB)] on the spindle monitor is in the range of 90 to 110 during the acceleration/ deceleration operation.

<If [AFLT gain (dB)] is out of the range of 90 to 110>

Adjust SP235(R2H) as follows and run the program created in [5] (acceleration/deceleration).

• When [AFLT gain (dB)] is smaller than 90:

Increment SP235(R2H) by 5 at a time until the gain reaches 90 or higher during the program execution.

• When [AFLT gain (dB)] is 111 or greater:

Decrement SP235(R2H) by 5 at a time until the gain reaches 110 or lower during the program execution.

[9] Stop the spindle when [Temperature (°C)] on the spindle monitor reaches 100 (or the upper limit of temperature in practical use).

[10] The value of SP235(R2H) you obtain at this time is the result of the final adjustment.

[2] Run the program (acceleration/deceleration) that you created in [5] of (1), and continue until [Temperature

(°C)] on the spindle monitor screen reaches 100 (or the upper limit of temperature in practical use).

[3] Stop the spindle when [Temperature (°C)] on the spindle monitor reaches 100 (or the upper limit of temperature in practical use). Then wait until [Temperature (°C)] drops to 80 (or the upper limit of temperature in practical use - 20°C).

[4] When [Temperature (°C)] on the spindle monitor reaches 80 (or the upper limit of temperature in practical use

- 20°C), run the program (acceleration/deceleration) you created in [5] of (1) by one cycle. Adjust SP236(WIH) as follows according to the value of [AFLT gain (dB)] on the spindle monitor screen during the operation.

• When [AFLT gain (dB)] is smaller than 90:

Increment SP236(WIH) by 2 at a time and perform [2]

• When [AFLT gain (dB)] is 111 or greater:

Decrement SP236(WIH) by 2 at a time and perform [2].

[5] The SP236(WIH) value to be obtained while [AFLT gain (dB)] is in the range of 90 to 110 is the result of the final adjustment.

[6] Set SP226 bit8 to 0. (Change SP226(SFNC6) from 0100 to 0000.)

*Change SP153 and SP185 back to the original settings and turn OFF and ON the NC

power.

CAUTION

Check the monitor screen to make sure that the motor has reached the maximum rotation speed in constant output during execution of the created program.

* "Maximum rotation speed in constant output" is the maximum speed at which the short-time rated output will not drop

lower than the motor’s specified output. (Refer to the motor output specifications.)

If the machine’s specified speed is lower than the motor’s maximum speed in constant output, the machine’s specified

speed serves as the maximum rotation speed.

7.1 Points of Caution and Confirmation

If an error occurs in the drive unit, the warning or alarm will occur. When a warning or alarm occurs, check the state while observing the following points, and inspect or remedy the unit according to the details given in this section.

< Points of confirmation >

[1] What is the alarm code display?

[2] Can the error or trouble be repeated? (Check alarm history)

[3] Is the motor and servo drive unit temperature and ambient temperature normal?

[4] Are the servo drive unit, control unit and motor grounded?

[5] Was the unit accelerating, decelerating or running at a set speed? What was the speed?

[6] Is there any difference during forward and backward run?

[7] Was there a momentary power failure?

[8] Did the trouble occur during a specific operation or command?

[9] At what frequency does the trouble occur?

[10] Is a load applied or removed?

[11] Has the drive unit been replaced, parts replaced or emergency measures taken?

[12] How many years has the unit been operating?

[13] Is the power supply voltage normal? Does the state change greatly according to the time band?

CAUTION

1. This power supply unit uses a large capacity electrolytic capacitor. When the CHARGE lamp on the front of the power supply unit is lit, voltage is still present at the PN terminal (TE2). Do not touch the terminal block in this state.

2. Before replacing the unit, etc., always confirm that there is no voltage at the PN terminal (TE2) with a tester or wait at least 15 minutes after turning the main power OFF.

3. The conductivity in the unit cannot be checked.

4. Never carry out a megger test on the drive unit or power supply unit as the unit could be damaged.

POINT

When the drive unit of E/EH Series which uses two cooling fans is in an emergency stop or alarm, one of fans (upper one in the case of vertical layout, or either one in the case of horizontal layout) is stopped and power-saving operation is performed. If the suspended fan is restarted by canceling the emergency stop, it is not a problem with the fan.

WARNING

1. Before starting maintenance or inspections, turn the main circuit power and control power both OFF.

Wait at least fifteen minutes for the CHARGE lamp to turn OFF, and then using a tester, confirm that the input and output voltage are zero. Failure to observe this could lead to electric shocks.

2. Inspections must be carried out by a qualified technician. Failure to observe this could lead to electric shocks. Contact your nearest Mitsubishi branch or dealer for repairs and part replacement.

CAUTION

1. Never perform a megger test (measure the insulation resistance) of the drive unit.

Failure to observe this could lead to faults.

2. The user must never disassemble or modify this product.

8.1 Periodic Inspections

8.1.1 Inspections

Periodic inspection of the following items is recommended.

[1] Are any of the screws on the terminal block loose? If loose, tighten them.

[2] Is any abnormal noise heard from the servo motor bearings or brake section?

[3] Are any of the cables damaged or cracked? If the cables move with the machine, periodically inspect the cables according to the working conditions.

[4] Is the core of the load coupling shaft deviated?

8.1.2 Cleaning of Spindle Motor

If you continue to use the spindle motor with dirt such as oil mist and dust adhered, its cooling performance degrades and the motor is unable to fully exercise its performance, which may cause the spindle motor overheat alarm. In some cases this may result in damage to the bearing or cooling fan. To ensure the cooling capability of the spindle motor's fan, carry out periodical cleaning of the spindle motor and its cooling fan according to the following cleaning procedure.

Note that the spindle motor SJ-D Series and the spindle motor SJ-VL Series is used as an example in this procedure.

When cleaning the other spindle motors, carry it out based on this procedure.

CAUTION

Do not touch the motor for some time after turning OFF the power, as the motor remains at a high temperature.

This may lead to burns.

Remarks

The standard replacement time is a reference. Even if the standard replacement time is not reached, the part must be replaced if any abnormality is found.

[1] Power smoothing capacitor:

The characteristics of the power smoothing capacitor will deteriorate due to the effect of ripple currents, etc. The capacitor life is greatly affected by the ambient temperature and working conditions. However, when used continuously in a normal air-conditioned environment (ambient temperature is an average of 40°C or less), the service life will be ten years.

[2] Relays:

Contact faults will occur due to contact wear caused by the switching current. The service life will be reached after

100,000 cumulative switches (switching life) although this will differ according to the power capacity.

[3] Servo motor bearings:

The motor bearings should be replaced after 20,000 to 30,000 hours of rated load operation at the rated speed.

This will be affected by the operation state, but the bearings must be replaced when any abnormal noise or vibration is found in the inspections.

[4] Servo motor oil seal, V-ring:

These parts should be replaced after 5,000 hours of operation at the rated speed. This will be affected by the operation state, but these parts must be replaced if oil leaks, etc., are found in the inspections.

11.When the unit has been stored for a long time, contact the Service Center.

12.Connect the encoder(CN2/CN3) immediately after the installation of the servo drive unit. In addition, when a battery box is used, immediately connect to the BTA/BTB connector. (prevention of absolute position data lost)

8.3.1 Replacing the Drive Unit

(1) Arrangement of replacing parts

Contact Mitsubishi branch or your dealer for an order or a replacement of the drive unit.

Place an order for the same type of a drive unit as the one to be replaced.

(2) Replacement procedure

Replace the drive unit with the following procedures.

Procedures

[1] Turn the breaker for the input power OFF. Make sure the CHARGE lamp of the power supply unit is turned

OFF.

[2] Disconnect all the connectors and the wires connected to the drive unit.

[3] Remove the two (four) screws fixing the drive unit onto the control panel. Remove the drive unit from the control panel.

[4] Make a same setting for the rotary switch and the dip switch of the new drive unit as those of the uninstalled drive unit.

[5] Install a new drive unit by following the removal procedure in reverse.

(3) Restoration

Data backup and restoration is not required before replacing drive units because drive units’ data such as parameters are stored in the controller. However, carry out a backup of the whole system before replacement as a precautionary measure.

The power for keeping the encoder’s position data of an absolute position system is supplied from the battery connected to the drive unit. Keep the power ON once for 30 minutes or more if possible, and make sure to complete the replacement within 60 minutes after charging the encoder’s capacitor.

9.1 Deceleration and Stop Function at Power Failure

The deceleration and stop function at power failure is a function to safely decelerate the servo axes and the spindle when a power failure occurs. This function prevents a damage on the machine due to an overrun of the servo axes, and at the same time, realizes a protection against overvoltage for high-speed IPM spindle motors and high-speed DDMs.

CAUTION

The power backup unit (MDS-D/DH-PFU) and regenerative resistor unit (R-UNIT6,7) options are required when using the deceleration and stop function at power failure.

9.2 Retraction function at power failure

The retraction function at power failure is a function to backup the power of the main circuit from the capacitor unit when a power failure occurs. For example, when power failure occurs during hobbing, tool escape by retraction operation can be realized using an NC command (hob retraction).

CAUTION

1. The power backup unit (MDS-D/DH-PFU) and capacitor unit (MDS-D/DH-CU) options are required when using the retraction function at power failure. Whether the regenerative resistor unit (R-UNIT6,7) is required or not is decided depending on the spindle stop operation (Deceleration and stop or Coast to a stop) at power failure.

2. Refer to the specifications manual of NC system for details on the NC settings relevant to the hob retraction function.

The drive unit offers the protection function.

Configure the system with the safety function compliant control units when using the safety function which satisfies the international standards.

Refer to NC specifications manual "Smart safety observation (BNP-C3072-022)" for details.

12.1.1 Outline of Protection Function

Function

Emergency stop observation

SLS

(Safely Limited Speed)

Details

NC control unit (CNC CPU unit) and the drive unit separately observe the input of emergency stop.

At the emergency stop, the motor power is shut off by controlling the contactor with each of the PLC

CPU unit (only for C80), NC control unit (CNC CPU unit) and the drive unit (power supply unit).

NC control unit (CNC CPU unit) and the drive unit (servo/spindle drive unit) separately observe the followings. The motor power is shut off when an error is detected during the observation.

-The command speed does not exceed the speed set with the parameter.

-The rotation speed of the motor does not exceed the rotation speed set with the parameter.

Protection function assumes the following configuration.

A)The machine is equipped with at least one safety door.

B)Safety is ensured when the safety door is closed.

When an operator requests to open the safety door, enable the safety function and release the lock on the safety door.

Safety is ensured by enabling the safety function while the safety door is open. When canceling the safety door open request, the safety door enters the locked state and safety function will be released.

WARNING

The sequence of enabling or disabling the safety function by opening or closing the door is required to take necessary actions at the machine tool builders.

12.2 Emergency Stop Observation

The double-protection for the emergency stop signal is provided and observes whether any abnormality is found in the emergency stop signal. The whole system will be in the emergency stop state when one emergency stop signal is in open state.

(1) Input circuit of an external emergency stop

Besides the emergency stop input from the NC controller, double-protection when an emergency stop occurs can be provided by directly inputting an external emergency stop to the CN24 connector on the power supply unit. Even if the emergency stop is not input from CNC for some reason, the contactors will be shut off by the external emergency stop input from CN24 connector on the power supply unit.

(2) Operation sequences of emergency stop

[1] Operation sequences of normal emergency stop

If the normal NC emergency stop and the external emergency stop are simultaneously input, the operation sequence will be the same as in the case of using only the NC emergency stop.

Immediately after the emergency stop is input, deceleration control is carried out in spindle control, and dynamic brake stop in servo control in a standard case, or deceleration control when the parameter is set. The ready signal is turned OFF after the NC confirms all axes stop, and the contactor control axis turns the contactor OFF.

Even when the NC emergency stop signal and the external emergency stop signal are not simultaneously input, the operation sequence will be the same as that of the normal emergency stop provided that both signals are input before all axes stop.

If only the external emergency stop is input, all the drive units that share one NC communication enter an emergency stop state and deceleration control (servo/spindle) or dynamic brake stop (servo) is executed. At this time, the axis to which the external emergency stop is input enters "in external emergency stop" (EA display). The contactor is turned OFF in accordance with the gate off delay time (SV055/SP055), as the NC emergency stop is not input and the ready signal is not turned OFF.

12.3 SLS (Safely Limited Speed) function

Safely Limited Speed function observes that the motors for servo and spindle do not exceed the specified speed when the safety door of the machine is open. The setup can be performed without shutting the machine power off and this contributes to reducing preparation time and improving operation. The speed is redundantly observed by the CPU of the drive unit and the NC control unit, and an alarm is issued when either one of the CPUs detect the speed command or speed feedback exceeds the specified speed, which lead to the deceleration control in the motor. The power is shut off by the STO (Safe Torque Off) function after the motor stops.

(1) Connection

The following three wirings are required for the SLS function.

[1] The state signal for the safety door of the machine is wired to both the NC unit side (DI) and drive unit side

(CN9 connector MPI1). The double-protection for the wiring must be provided by wiring the signal to each of the NC side and drive unit side as the following figure.

[2] Add the wiring to control the contactor in the NC unit side in order to shut the power when an error occurs.

[3] In addition to the emergency stop wiring for the NC unit, add the external emergency stop wiring for the CN24 connector of the power supply unit.

14.1 Introduction

As the NC unit is a component designed to control machine tools, it is believed to be out of the direct EMC Directives/

Electromagnetic Compatibility Regulations subject. However, we would like to introduce the following measure plans to backup EMC Directives/Electromagnetic Compatibility Regulations compliance of the machine tool as the NC unit is a major component of the machine tools.

[1] Methods for installation in control/operation panel

[2] Methods of wiring cable outside of panel

[3] Introduction of countermeasure parts

Mitsubishi is carrying out tests to confirm the compliance to the EMC Directives/Electromagnetic Compatibility Regulations under the environment described in this manual. However, the level of the noise will differ according to the equipment type and layout, control panel structure and wiring lead-in, etc. Thus, we ask that the final noise level be confirmed by the machine tool builder.

For measures for CNC, refer to "EMC INSTALLATION GUIDELINES" of each NC Connection Manual.

14.2 EMC Directives/Electromagnetic Compatibility Regulations

The EMC Directives/Electromagnetic Compatibility Regulations regulate mainly the following two withstand levels.

Emission ..... Capacity to prevent output of obstructive noise that adversely affects external sources.

Immunity ..... Capacity not to malfunction due to obstructive noise from external sources.

The details of each level are classified in the table below. It is assumed that the Standards and test details required for a machine tool are about the same as these.

14 Appx. 5: EMC Installation Guidelines

14.3 EMC Measures

The main items relating to EMC measures include the following.

[1] Store the device in an electrically sealed metal panel.

[2] Earth all conductors that are floating electrically. (Lower the impedance.)

[3] Wire the power line separated from the signal wire as far as possible.

[4] Use shielded wires for the cables wired outside of the panel.

[5] Install a noise filter.

Ensure the following items to suppress noise radiated outside of the panel.

[1] Accurately ground the devices.

[2] Clamp shielded wires in the control panel.

[3] Increase the panel's electrical seal. Reduce the gap and hole size.

Note that the electromagnetic noise radiated in the air is greatly affected by the clearance of the panel and the quality of the cable shield.

14.4 Measures for Panel Structure

The design of the panel is a very important factor for the EMC measures, so take the following measures into consideration.

14.4.1 Measures for Control Panel Unit

[1] Use metal for all materials configuring the panel.

[2] For the joining of the top plate and side plates, etc., mask the contact surface with paint, and fix with welding or screws so that the impedance is reduced. In either case, keep the joining clearance to a max. of 20cm for a better effect.

Note that if the plate warps due to the screw fixing, etc., creating a clearance, noise could leak from that place.

 

Painting mask

 

Max. joining   clearance 20cm or less

[3] Plate the earth plate (with nickel, tin), and connect the connections with a low impedance.

[4] If there is an opening on the panel surface, such as the ventilation holes, cover it with a metal plate or expanded metal.

Make sure not to connect using metal or a conductor without peeling off the surface, which results in an insufficient electrical connection. (ex. connection by putting painted surfaces together)

 

Example ) 

Metal plate or expanded metal

Opening

3cm〜5cm  

* Provide electrical conductance

503 IB-1501229-H

MDS-E/EH Series Instruction Manual

14 Appx. 5: EMC Installation Guidelines

14.4.2 Measures for Door

[1] Use metal for all materials configuring the door.

[2] Use an EMI gasket or conductive packing for the contact between the door and control panel unit.

[3] The EMI gasket or conductive packing must contact at a uniform and correct position of the metal surface of the control panel unit.

[4] The surface of the control panel unit contacted with the EMI gasket or conductive packing must have conductance treatment.

(Example) Weld (or screw) a plate that is plated (with nickel, tin).

 

EMI gasket

Packing

 

Carry out conductance treatment on sections that the EMI gasket contacts.

[5] As a method other than the above, the control panel unit and door can be connected with a plain braided wire. In this case, the panel and door should be contacted at as many points as possible.

14.4.3 Measures for Operation Board Panel

[1] Always connect the operation board and indicator with an earthing wire.

[2] If the operation board panel has a door, use an EMI gasket or conductive packing between the door and panel to provide electrical conductance in the same manner as the control panel.

[3] Connect the operation board panel and control panel with a sufficiently thick and short earthing wire.

14.4.4 Shielding of the Power Supply Input Section

[1] Separate the input power supply section from other parts in the control panel so that the input power supply cable will not be contaminated by radiated noise.

[2] Do not lead the power line through the panel without passing it through a filter.

14.5 Measures for Various Cables

The various cables act as antennas for the noise and discharge the noise externally. Thus appropriate treatment is required to avoid the noise.

The wiring between the drive unit and motor act as an extremely powerful noise source, so apply the following measures.

14.5.1 Measures for Wiring in Panel

[1] If the cables are led unnecessarily in the panel, they will easily pick up the radiated noise. Thus, keep the wiring length as short as possible.

 

Noise Noise

Device Device Device

Device Device Device

[2] The noise from other devices will enter the cable and be discharged externally, so avoid internal wiring near the openings.

  Control panel Control panel

Device Device

Device Device

[3] Connect the control device earthing terminal and earthing plate with a thick wire. Take care to the leading of the wire.

14.5.2 Measures for Shield Treatment

Common items

Use of shield clamp fittings is recommended for treating the shields. The fittings are available as options, so order as required. (Refer to the section "Shield Clamp Fitting" in this chapter.)

Clamp the shield at a position within 10cm from the panel lead out port.

POINT

1. When leading the cables, including the grounding wire (FG), outside of the panel, clamp the cables near the panel outlet

(recommendation: within 10cm).

2. When using a metal duct or conduit, the cables do not need to be clamped near the panel outlet.

3. When leading cables not having shields outside the panel, follow the instructions given for each cable. (Installation of a ferrite core, etc., may be required.)

[3] Earth the shield with a metal P clip or U clip.

(A cable clamp fitting can be used depending on the wire size.)

[4] Directly earth the shield. Do not solder the braided shield onto a wire and earth the end of the wire.

Solder

[5] When not using a shield cable for the power cable, use a conventional cabtyre cable. Use a metal conduit outside the cable.

[6] Earth the power cable on the control panel side at the contact surface of the conduit connector and control panel.

(Mask the side wall of the control panel with paint.)

[7] Follow the treatment shown in the example for the conduit connector to earth the power cable on the motor side.

14.6.1 Shield Clamp Fitting

The effect can be enhanced by connecting the cable directly to the earthing plate. Install an earthing plate near each panel's outlet (within 10cm), and press the cable against the earthing plate with the clamp fitting. If the cables are thin, several can be bundled and clamped together. Securely earth the earthing plate with the frame ground. Install directly on the cabinet or connect with an earthing wire.

Peel the cable sheath at the clamp section.

14.6.2 Ferrite Core

Noise can be suppressed by installing a ferrite core to the cable if the power cable and encoder cable, which are led from outside of the control panel, are the noise sources.

Specify the frequency of radiated noise and select the ferrite with high impedance corresponding to the frequency.

By wrapping the cable around the ferrite core according to the cable diameter as shown in the example, the impedance rises, obtaining a better effect.

< Example of use >

Lead through one time

(one turn)

Lead through two times

(two turns)

Lead through three times

(three turns)

The clearance between the ferrite core and cable must be as narrow as possible when winding a cable.

IB-1501229-H 508

MDS-E/EH Series Instruction Manual

14 Appx. 5: EMC Installation Guidelines

< Recommended ferrite core >

A ferrite core is integrated and mounted on the plastic case. Quick installation is possible without cutting the interface cable or power cable. This ferrite core is effective against common mode noise, allowing measures against noise to be taken without affecting the signal quality.

< Example of surge absorber installation >

An example of installing the surge absorber in the machine control panel is shown below.

A short-circuit fault will occur in the surge absorber if a surge exceeding the tolerance is applied. Thus, install a circuit protector in the stage before the surge absorber. Note that almost no current flows to the surge absorber during normal use, so a circuit protector installed as the circuit protection for another device can be used for the surge absorber.

CAUTION

1. The wires from the surge absorber should be connected without extensions.

2. If the surge absorber cannot be installed just with the enclosed wires, keep the wiring length of A to 2m or less. If the wires are long, the surge absorber's performance may drop and inhibit protection of the devices in the panel.

3. Surge absorber to be selected varies depending on input power voltage.

4. Do not insert the surge absorber in the place with a lot of harmonic components.
