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.
After assembling the built-in IPM 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 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 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.
(2)Transportation and storage

(Note 2) -15°C to 55°C for linear servo motor.
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 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 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, Service Station, Sales Office or delayer.
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.
Servo drive unit
Do not reverse the direction of a diode which
COM
connect to a DC relay for the control output
(24VDC)
signals such as contractor and motor brake
output, etc. to suppress a surge. Connecting it

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.
Always separate the signals wires from the drive wire and 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

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, tolerable sudden power failure time, 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.
(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.

2.1.2 Precautions for Storage
(1) If water, dust or foreign matters, etc., adhere or enter the parts, problems such as rust or decrease in the insulation
resistivity may occur. This will prevent maintenance of satisfying quality and functions.
Always store the motor indoors, and protect the motor by covering it with a sheet, etc.
(2) To prevent the coils from absorbing water and to prevent the steel center and other metallic parts from rusting due
to water entering and internal sweating, place the entire product in a polyethylene bag, etc., insert 0.5kg/m3 of
dehumidifier (silica gel), and seal the bag when storing for six months or longer. Use a dehumidifier that shows the
degree of absorption, and when 50% (changes from blue to pink) is reached, replace the agent, or dry it to use
again.
Remove all dehumidifiers before using the motor again.
(3) Measure the insulation resistivity of the coils before using a stator that has been stored. Confirm that it is 10M
more at room temperature (use a 500V insulation resistance tester). If the insulation resistance is less than 10M
dry the stator in a dryer that does not exceed 90°C until the insulation resistance is restored.

4.1 Stator Assembly
(1) Shrink fitting interference within the housing
Shrink fitting is recommended for the matching of the stator and housing (cooling jacket, external sleeve, etc.). The
recommended values for the shrink fitting interference are given below. If the interference amount is near the upper
limit, the housing outer diameter may expand after shrink fitting. Thus, machining the housing outer diameter after
shrink fitting is recommended. If expansion at the housing outer diameter after shrink fitting is not permissible,
match the size the housing inner diameter according to the stator outer diameter so that the shrink fitting
interference is within the reference values given below.

< When recommended interference cannot be ensured >
When recommended interference cannot be ensured for the matching of the stator and housing, a stopper must be
created with the set pins. The recommended set pin dimensions and machinable depth of the set holes are shown
below. The stator coils may be damaged if the set holes are deeper than the dimensions given below. If pins that
are too long are used or if excessive force is applied when inserting the pins, an excessive force will be applied onto
the layered steel plates inside the set pin section causing them to project into the stator or may damage the coils.

< Installation of the set pin >
Avoid inserting the set pin into the welded section on the circumference of the stator core, the clamp section or
notched section. Insert the set pin near the center of the core width. Fill the top of the pin with epoxy resin after
inserting the pins so that the cooling fluid will not leak out.

Machining accuracy of the housing inner diameter
Use the values given below as a guideline for the machining precision of the housing inner diameter. It is
recommended that a push-in guide section that is 0.5-1mm larger than the housing diameter be created.

Handling the stator
Take care not to apply an external force to the coil ends of the stator
or allow foreign matters to stick to it. An insulation defect may occur if chemicals or metallic dust stick to the coil
end, or if there are bumps or scratches on the coil end. Do not place the stator directly onto a table or the floor, but
use jigs as shown below. Place the stator sideways when possible, and do not stack more than three layers.

4 Assembly and Installation
CAUTION
1. Prepare a cylindrical jig when pressing the stator into the housing. Press the stator core end, and never press the coil
end.
2. If the stator and housing are shrink fit assembled, it may be difficult to pull the stator out of the housing. Confirm the
position of the lead wire inlets before assembly.
3. The layered steel of the stator with an outer diameter of Φ229.5 or more is caulked with clamp plates. The clamp plates
will protrude 2.5-5mm from the state core end, so take care when making a step for positioning on the inner diameter of
the housing or when preparing a jig. An example of the clamp plate positions is shown below.
Eight clamp plates
2.5~5mm
4. The stator core is layered steel that is fixed by welding or caulking, so the end may be wavy.
5. Re-machining the stator outer diameter is not recommended. When inevitable, completely cover the coil end with tape,
etc., so that the cutting powder does not adhere on the coil end, and use dry machining when possible.
(4) Installation to the housing
An example of shrink fitting the housing to the stator is shown below. Hold the stator with a jig so that the coil end is
not damaged. Evenly heat the housing with an electric furnace, and when using an oil vat, use insulating oil. The
housing has a small heat capacity and easily cools down, so carry out the operation swiftly. When using the
interference shown in section (1), the housing heating temperature should be between 120 - 150°C for the
recommended interference in item (1).

1. A 0.1mm curve may occur to the outer diameter as the stator is made of layered steel. However, after assembling, the
stator will fit to the housing diameter, so reference value of the stator outer diameter is that shown in the diameter
dimension diagram.
2. Do not apply excessive shocks to the stator that is not assembled into the housing.

Checking for the stator and housing insulation and the stator coil resistance
Check the following items between the stator terminal and the housing after assembling the stator into the housing.
(a)Insulation resistivity 10M or higher at room temperature (use a 500V insulation resistance tester)
(b)Dielectric strength
AC1500V/min.
When measuring the stator coil resistivity, use a resistance tester that has a low resistance measurement range.
The coil resistivity is low at 1 or less, so the measurement error will be large if there is a contact resistivity, etc., in
the measurement circuit when a general-purpose tester is used. If a solderless terminal is installed on the lead wire,
a contact resistance may occur due to the oxidized film on the solderless terminal surface. Hold the terminal with a
clip, and move the clip two to three times before measuring.

4.2 Rotor Assembly
(1) Rotor installation to the shaft
•
Shrink fitting is recommended for fixing the rotor to the shaft or sleeve. The shrink fit interference will differ
according to the type, so refer to the motor outline diagram. If the recommended interference width is small,
match and machine the shaft or sleeve outer diameter.
•
When shrink fitting the shaft or sleeve onto the rotor, heat the rotor in an electrical furnace so that the
temperature of each part is even. The recommended heating temperature is 300-350°C for IM rotor and 130°C
or less for IPM rotor. If the heating is improper or if uneven, trouble may occur. The upper limit of the rotor
temperature is 400°C or less on the rotor surface.
•
The inside surface of the rotor is not machined unless a special note is made on the outline diagram.
Remember that the rotor is weak as the rotor core is composed of layered steel when selecting the machining
conditions for finish machining. Machining with difficult conditions may cause the steel plates to deform or peel.
CAUTION
1. The rotor before shrink fitting is weak, so take care not to apply strong impacts to it. Take care not to let foreign matters
(metallic powder, etc.) enter the rotor before assembling.
2. The inner diameter and outer diameter may have an approximately 0.1mm curve as the rotor core is composed of
layered steel. However, when the rotor is shrink fit, it will be resolved, so the dimensions noted in the outline diagram can
be used for the reference value of the rotor inner diameter.
3. Use a magnetic material for the shaft.
4. Some rotor types have a groove to be used as a guide when layering the steel plates, however, do not use this to fix the
rotor.

Lead
Coil end

Lead side outline diagram
5. If the heating is improper or if uneven, trouble may occur. Be careful that the recommended heating temperature differs
between IM and IPM.
6. The material of the end ring for the high-speed series rotor differs from the standard series rotor, so strict temperature
control is necessary when the rotor is heated.
7. The oils on the rotor may evaporate and generate a gas when the rotor is heated, so ventilate the area well.
8. Natural cooling is recommended after shrink fitting the rotor.
9. A slight strain may occur on the shaft from the rotor shrink fitting, so finish machine the parts that require precision after
shrink fitting.

It is recommended that a push-in guide 0.1 to 0.3mm smaller than the outer diameter of the rotor fixing part be
created on the shaft.
(2) Finish machining of the rotor
•
The rotor outer diameter is not finish machined, so finish machine the rotor outer diameter to the dimensions
specified on the outline diameter after shrink fitting. The finish amount will be more than 0.15mm unless
otherwise specified in the outline drawings.
(Note) Never carry out a machining on the IPM rotor.
•
Dry machining should be used on the machining of the rotor's outer diameter to prevent corrosion of the steel
or aluminum. If dielectric fluid must be used, use noncorrosive, and dry the part completely after machining. If
dielectric fluid remains between the layered steel, the rotor balance may be lost.
•
Applying an anti-corrosive agent onto the rotor after machining the rotor's outer diameter is recommended.
(3) Balancing
•
The dynamic balance of the rotor unit has not been adjusted. Adjust the balance by opening a hole in the
balance ring installed by the user.
•
Install balance rings in front and back of the rotor. The unbalance of the rotor will cause vibration and noise
during high speed operation.
•
Do not machine the rotor core and end ring when adjusting the balance. If the rotor end ring has a protrusion
as shown below, the protrusion may be cut off to adjust the balance, but this must be used as a measure for
fine adjustment. Take care not to scratch the ring-shaped part at this time.
Rotor core
This part (shadowed with slanted lines)
is a ring section.
This part cannot be machined as a
current flows through.
This section has eight blades and eight protrusions.
Only this part can be machined.
Some models may not have either the blades or
protrusions.
In this case, there is no machinable area.

(1) Ensuring the space for the stator coil end
•
The coil end dimensions are as shown in the outline diagram but the minimum value of the coil end inner
diameter must take the stator inner diameter into consideration. The coil end is made of a congregation of coil
ends, so there may be an inconsistency in the shape and dimensions. Leave at least 5mm between the
structure and the coil end assuming that the coil end might exist in the areas indicated with cross-lines in the
diagram below.

(2) Cautions for assembling
•
Install a cooling jacket around the stator and use fluid cooling (oil cooling).
•
Take care so that water, cutting fluid or conductive oils do not contact the stator coil ends. Also, make sure to
prevent non-conductive oils from contacting the structure.
•
Leave a space of 5mm or more between the stator coil ends and the structure.
•
Create a grounding terminal on the machine side structure (stator housing, etc.), and connect with the
controller grounding terminal.
•
Chamfer or round the corners so that the lead wires from the stator are not damaged by the inlet edges.
•
The deviation in the stator and rotor shaft direction must be ±2mm or less. If the core width is smaller than
100mm, the deviation must be ±2% or less of the core width.
•
The unbalance between the stator and rotor must be less than ±5% of the specified gap shown in the outline
diagram.
•
Create a structure that will prevent foreign matter from entering the encoder balance section and encoder
gears. Make sure that the structure allows repairs and replacement.
•
Unless otherwise noted in the outline drawing, there are no limits to the installation direction of the stator and
motor. The stator and motor combination can be changed without problems if the same motor specifications
are used.
•
When machining the housing outer diameter after assembling the stator onto the housing, cover the coil ends
with tape, etc., so that the cutting chips do not adhere onto the coil. Any chips on the coil will cause defective
insulation.

4.4 Precautions for Handling IPM Spindle Motor
4.4.1 Precautions
The built-in IPM spindle motor rotor has a core in which permanent magnets are arranged. Very strong magnetic attraction
force is generated between magnetic material as iron. The magnetic attraction force is generated mainly on the core surface
side (rotor outside). (Almost no attraction force is generated on the sleeve inside.)
Therefore, when handling the single rotor unit, take safety measure to avoid accidents as fingers or hands may be caught due
to the magnetic attraction force.
In addition, the magnetic force is released into the air, so it is highly dangerous to approach the rotor before assembling
because medical electronics such as pacemaker may not operate normally.
Please note that if watch, magnetic tape, floppy disk, cash card, prepaid card, ticket etc., are approached, their magnetic
memories may be destroyed or magnetized and may not be able to use due to the magnetic force.
< General precautions>
(1) Do not put magnetic materials as iron close to the single rotor unit.
Permanent
magnet

Permanent magnets are embedded.
Core section
(2) Before handling, remove metal items such as watch, piercing jewelry, necklace, etc.
(3) Do not leave the rotor unattended.
-> When the rotor is not securely fixed to the machine or device, make sure to store it in the package properly.
(4) Do not modify the product, or do not give a shock.
(5) Do not get on top of or place heavy objects on the product.
< Transportation and storage >
(1) Correctly store the rotor in the package to transport and store.
(2) During transportation and storage, draw people's attention by applying a notice saying "Strong magnet-Handle with
care" to the package or storage shelf.
(3) Do not use a damaged package.
4 - 12
Built-in Spindle Motor SJ-B Series Specifications and Instruction Manual
4.4 Precautions for Handling IPM Spindle Motor
< Assembly >
(1) For the rotor shrink fitting to the spindle, the rotor should be heated at 130°C or less. If it exceeds the temperature,
the magnet could be demagnetized, and the specified characteristics will not be ensured.
(2) For the rotor shrink fitting, refer to the recommended value as shown in the delivery specifications (outline
dimension drawings).
(3) Finishing machining for the rotor has already been performed, so do not modify such as the outer and inner
diameters.
Tools may be attracted or cutting chips may stick onto the rotor surface due to magnetic attraction force.
(4) At the start of inserting a spindle with a rotor into a stator, the magnetic force attracting to the stator side is
generated. Use a jig, etc. so as not to catch your hand or fingers.

Example of assembling a rotor
(5)
The dynamic balance of the rotor has not been adjusted. After the rotor is assembled to the spindle, adjust the
dynamic balance. Adjust the balance by opening a hole in the balance ring installed by the user.
(6) After assembling the spindle, if the rotor is rotated by hand etc., voltage occurs between the terminals of lead. Take
care not to get electric shocks.

4.5.1 Accuracy Encoder (TS5690 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.

Keep the deflection of the outer diameter, when the detection gears are installed on the shaft, to 0.02mm or
less.
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.
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.

4.5 Installation of Motor Encoder
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 (M5 x 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
22.5±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.

(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)
2)
3)
4)
5)
6)
Power ON the spindle drive unit and the NC.
Set the spindle parameter #13018/bit1 (SP018/bit1) to 1, and set to an open loop control.
Turn the NC power OFF and then ON again.
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.
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.
Set the spindle parameter #13018/bit1 (SP018/bit1) to 0 again and finish the open loop control.
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.

Failure to observe this could lead to electric shocks.
3. Securely ground the drive units and spindle motor.
4. Wire the drive units and 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 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. Electronic devices used near the drive units may receive magnetic obstruction. Reduce the effect of magnetic obstacles
by installing a noise filter, etc.
5. Do not install a phase advancing capacitor, surge absorber or radio noise filter on the power line (U, V, W) of the spindle
motor.
6. Do not modify this unit.
7. If the connectors are connected incorrectly, faults could occur. Make sure that the connecting position and the
connection are correct.
8. 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.

6.1 Initial Setup for IPM Spindle Motor
This section explains the initial setup procedures for IPM spindle motor system.
CAUTION
1. Perform the initial setup after the operation is enabled for NC system.
2. The initial setup is required for each IPM spindle motor.
3. Perform the initial setup again after replacing the encoder.
6.1.1 Adjustment Procedure
In the IPM spindle motor drive system, create the initial magnetic pole by the method listed below after the power ON.
The DC excitation function detects the magnetic pole shift amount on the Z-phase basis when using an IPM spindle
motor, so the IPM spindle motor will be driven with the initial magnetic pole and perform the DC excitation function
(decision of the magnetic pole shift amount) after the Z-phase has been passed.

The IPM spindle motor will be driven according to the magnetic pole shift amount set in the spindle parameter
#13118(SP118), which you determined through the DC excitation function, after turning the NC power ON next and the
Z-phase has been passed. (The IPM spindle motor will be driven with the initial magnetic pole in the above table until the
Z-phase has been passed even after the magnetic pole shift amount is set.)
With the DC excitation function, once the spindle parameter #13118(SP118) is set, resetting is not required unless the
encoder is replaced.
< Confirmation of the initial magnetic polar detection >
(1) Turn ON the spindle drive unit and NC. Confirm that there is no error such as Initial parameter error (37).
(2) Release the emergency stop and then start the spindle with S command.
-> When pulse-applied method is not used, the parameters related to the initial magnetic pole estimate function
are required to be set.
(#13121(SP121) to 6, #13122(SP122) to 1500, and #13123(SP123) to 2000)
(3) The LED on the drive unit changes to "Cx" and the IPM spindle motor moves by little and little for about five seconds
(start initial magnetic pole estimate).
(4) Confirm that the LED on the drive unit changes to "dx" and the motor stops (terminate initial magnetic pole
estimate).
[Check] Spindle monitor Control output 1/bit1(In servo ON) changes from "0" to "1"
Control output 4/bit7(Magnetic pole position not set) changes from "1" to "0"
(5) The IPM spindle motor will be driven after the operation (4). Drive the motor until the Z-phase has been detected.
-> Switch to the [Servo diagn] menu on the NC maintenance screen, select [Servo unit] and confirm [Control
output 2/bit0(Z-phase passed)] is "1".

< DC excitation function >
(6) Turn ON the emergency stop.
(7) Set the parameters related to the DC excitation (#13125(SP125) to 10, #13126(SP126) to 10, and #13127(SP127)
to 1000).
(8) Set the spindle parameter #13225/bit4(SP225/bit4) to "1" to enable the DC excitation mode.
(9) Release the emergency stop.
(10) Confirm that the IPM spindle motor carries out a reciprocation operation between about ±10° and 20° once (start
DC excitation).
(11) Confirm that the IPM spindle motor stops after the reciprocation operation.
(12) Switch to the [Diagn] menu on the NC maintenance screen, select [Spindle unit] and monitor [AFLT gain].
(13) Turn ON the emergency stop (terminate DC excitation).
(14) Repeat (9) to (13) 5 times, and monitor the ALFT gain value (magnetic pole shift amount) each time.
If difference of the magnetic pole shift amounts is 1000 data or bigger, reset the related parameter settings
(#13125(SP125)=+10, #13126(SP126)=+10) and perform (9) to (13) again.
(15) Calculate the average of the magnetic pole shift amounts, and set it to #13118(SP118).
(16) Return the spindle parameter #13225/bit4(SP225/bit4) back to the original setting, "0".
(17) Turn the NC power ON again.
CAUTION
1. Never operate the IPM spindle motor before DC excitation function is enabled.
2. The motor carries out a reciprocation operation at about the magnetic pole pitch while DC excitation function is enabled.
3. The magnetic pole shift amount cannot be calculated correctly with incorrect wiring in the motor power line or encoder
cable.
