Safety Precautions

 Confirmations upon Delivery

CAUTION

• Never install an Inverter that is damaged or missing components.

Doing so can result in injury.

 Installation

CAUTION

• Always hold the case when carrying the Inverter.

If the Inverter is held by the front cover, the main body of the Inverter may fall, possibly resulting in injury.

• Attach the Inverter to a metal or other noncombustible material.

Fire can result if the Inverter is attached to a combustible material.

• Install a cooling fan or other cooling device when installing more than one Inverter in the same enclosure so that the temperature of the air entering the Inverters is below 45 ° C.

Overheating can result in fires or other accidents.

 Wiring

WARNING

• Always turn OFF the input power supply before wiring terminals.

Otherwise, an electric shock or fire can occur.

• Wiring must be performed by an authorized person qualified in electrical work.

Otherwise, an electric shock or fire can occur.

• Be sure to ground the ground terminal. (200 V Class: Ground to 100 Ω or less, 400 V Class:

Ground to 10 Ω or less)

Otherwise, an electric shock or fire can occur.

• Always check the operation of any emergency stop circuits after they are wired.

Otherwise, there is the possibility of injury. (Wiring is the responsibility of the user.)

• Never touch the output terminals directly with your hands or allow the output lines to come into contact with the Inverter case. Never short the output circuits.

Otherwise, an electric shock or ground short can occur.

• If the power supply is turned ON during the FWD (or REV) Run Command is given, the motor will start automatically.

Turn the power supply ON after verifying that the RUN signal is OFF.

Failure to observe this warning may result in injury.

• When the 3-wire sequence is set, do not make the wiring for the control circuit unless the multifunction input terminal constant is set.

Failure to observe this warning may result in injury.

CAUTION

• Check to be sure that the voltage of the main AC power supply satisfies the rated voltage of the

Inverter.

Injury or fire can occur if the voltage is not correct.

• Do not perform voltage withstand tests on the Inverter.

Otherwise, semiconductor elements and other devices can be damaged.

• Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the I/O wiring examples.

Otherwise, a fire can occur.

iii

CAUTION

• Tighten all terminal screws to the specified tightening torque.

Otherwise, a fire may occur.

• Do not connect AC power to output terminals U, V, and W.

The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.

• Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits.

The Inverter can be damaged or interior parts burnt if these devices are connected.

• Do not connect electromagnetic switches or magnetic contactors to the output circuits.

If a load is connected while the Inverter is operating, surge current will cause the overcurrent protection circuit inside the

Inverter to operate.

 Setting User Constants

CAUTION

• Disconnect the load (machine, device) from the motor before performing rotational autotuning.

The motor may turn, possibly resulting in injury or damage to equipment. Also, motor constants cannot be correctly set with the motor attached to a load.

• Stay clear of the motor during rotational autotuning.

The motor repeats running and stopping until autotuning has been completed, possibly resulting in injury.

• In stationary autotuning 1, when the motor is first operated in the drive mode after tuning, the remaining motor constants E2-02 (Motor rated slip) and E2-03 (Motor no-load current) are set automatically. To perform an operation immediately after stationary autotuning 1, use the following procedure under the recommended conditions.

(1) Check the values of E2-02 and E2-03 in verify mode or advanced programming mode.

(2) Run the motor once in drive mode under the following conditions.

• The Inverter and the motor are connected.

• The motor shaft is not locked with a mechanical brake or other stopping mechanism (or function).

• A motor-load ratio of 30% or less is maintained.

• A speed of 30% or more of the base frequency set at E1-06 (default = highest frequency) is maintained at a constant speed for one second or more.

(3) After stopping the motor, check the values of E2-02 and E2-03 again in verify mode or advanced programming mode. If the values of E2-02 and E2-03 differ from the ones before the first operation was carried out, the settings have been successfully completed. Next, check if the values are suitable or not.

If the values of E2-02 and E2-03 differed greatly from the reference data of the motor in the test report or the instruction manual (TOE-S616-55.1), hunting, motor vibrations, insufficient motor torque, or an overcurrent may occur because the motor is operated although the aforementioned conditions have not been fulfilled after stationary autotuning 1. For elevators, failure to observe this caution may result in the cage falling or injury. If so, perform stationary autotuning 1 again and run the motor using the aforementioned procedure under the recommended conditions or perform stationary autotuning 2 or rotational autotuning.

Usually the standard setting for E2-02 is 1 Hz to 3 Hz, and that for E2-03 is 30 % to 65 % of the rated current for a generalpurpose motor. Generally, the larger the motor capacity is, the smaller the rated slip and the ratio of the no-load current to the rated current become. Use the data given in Factory Settings that Change with the Inverter Capacity (o2-04) of Chapter 5 User Constants as a reference.

 Trial Operation

WARNING

• Check to be sure that the front cover is attached before turning ON the power supply.

An electric shock may occur.

• Do not come close to the machine when the fault reset function is used. If the alarmed is cleared, the machine may start moving suddenly.

Also, design the machine so that human safety is ensured even when it is restarted.

Injury may occur.

• Provide a separate emergency stop switch; the Digital Operator STOP Key is valid only when its function is set.

Injury may occur.

• Reset alarms only after confirming that the RUN signal is OFF.

Injury may occur.

CAUTION

• Don't touch the radiation fins (heatsink), braking resistor, or Braking Resistor Unit. These can become very hot.

Otherwise, a burn injury may occur.

• Be sure that the motor and machine is within the applicable ranges before starting operation.

Otherwise, an injury may occur.

• Provide a separate holding brake if necessary.

Always construct the external sequence to confirm that the holding brake is activated in the event of an emergency, a power failure, or an abnormality in the Inverter.

Failure to observe this caution can result in injury.

• If using an Inverter with an elevator, take safety measures on the elevator to prevent the elevator from dropping.

Failure to observe this caution can result in injury.

• Don't check signals while the Inverter is running.

Otherwise, the equipment may be damaged.

• Be careful when changing Inverter settings. The Inverter is factory set to suitable settings.

Otherwise, the equipment may be damaged.

 Maintenance and Inspection

WARNING

• Do not touch the Inverter terminals. Some of the terminals carry high voltages and are extremely dangerous.

Doing so can result in electric shock.

• Always have the protective cover in place when power is being supplied to the Inverter. When attaching the cover, always turn OFF power to the Inverter through the MCCB.

Doing so can result in electric shock.

• Turn OFF the main circuit power supply, wait for the time indicated on the front cover, and make sure the CHARGE indicator light has gone out, and then perform maintenance and inspection.

The capacitor will remain charged and is dangerous.

• Maintenance, inspection, and replacement of parts must be performed only by authorized personnel.

Remove all metal objects, such as watches and rings, before starting work. Always use grounded tools.

Failure to heed these warning can result in electric shock.

CAUTION

• A CMOS IC is used in the control board. Handle the control board and CMOS IC carefully.

The CMOS IC can be destroyed by static electricity if touched directly.

• Do not change the wiring, or remove connectors or the Digital Operator, during operation.

Doing so can result in personal injury.

 Other

• Do not attempt to modify or alter the Inverter.

Doing so can result in electrical shock or injury.

Protected so that parts of the human body cannot reach electrically charged parts from the front when the

Inverter is mounted in a control panel.

Enclosed Wall-mounted Type (IEC IP20, NEMA 1 (Type 1))

The Inverter is structured so that the Inverter is shielded from the exterior, and can thus be mounted to the interior wall of a standard building (not necessarily enclosed in a control panel). The protective structure conforms to the standards of NEMA 1 (Type 1) in the USA. The protective covers (see Fig. 1.4

) are required for an IEC IP20 or NEMA 1 (Type 1) protective structure.

Fig 1.13 Mounting the Digital Operator

IMPORTANT

1. Do not remove or attach the Digital Operator or mount or remove the front cover using methods other than those described above, otherwise the Inverter may break or malfunction due to imperfect contact.

2. Never attach the front cover to the Inverter with the Digital Operator attached to the front cover. Imperfect contact can result.

Always attach the front cover to the Inverter by itself first, and then attach the Digital Operator to the front cover.

Inverters of 22 kW or More

For Inverter with an output of 22 kW or more, remove the terminal cover and then use the following procedures to remove the Digital Operator and front cover.

Removing the Digital Operator

Use the same procedure as for Inverters with an output of 18.5 kW or less.

IMPORTANT

1. Control circuit terminals are arranged as shown below.

Inverters with SPEC: C or earlier

Inverters with SPEC: E or later

2. The output current capacity of the +V, -V terminal is 20 mA.

3. Disable the stall prevention during deceleration (set constant L3-04 to 0) when using a Braking Resistor

Unit. If this user constant is not changed to disable stall prevention, the system may not stop during deceleration.

4. Main circuit terminals are indicated with double circles and control circuit terminals are indicated with single circles.

5. The wiring for a motor with a cooling fan is not required for self-cooling motors.

6. PG circuit wiring (i.e., wiring to the PG-B2 Board) is not required for control without a PG.

7. Sequence input signals S1 to S8 are labeled for sequence connections (0 V common and sinking mode) for no-voltage contacts or NPN transistors. These are the default settings.

For PNP transistor sequence connections (+24V common and sourcing mode) or to provide a 24-V external power supply, refer to Table 2.13

8. The master speed frequency reference can set to input either a voltage (terminal A1) or current (terminal

A2) by changing the setting of parameter H3-13. The default setting is for a voltage reference input.

9. The multi-function analog output is a dedicated meter output for an analog frequency meter, ammeter, voltmeter, wattmeter, etc. Do not use this output for feedback control or for any other control purpose.

10.DC reactors to improve the input power factor are built into 200 V Class Inverters for 22 to 110 kW and 400

V Class Inverters for 22 to 300 kW. A DC reactor is thus an option only for Inverters for 18.5 kW or less.

11.Set parameter L8-01 to 1 when using a breaking resistor (ERF). When using a Braking Resistor Unit, a shutoff sequence for the power supply must be made using a thermal relay trip.

12.The permissible load of a multi-function contact output and an error contact output is 10 mA. Use a multifunction open-collector output for a load less than 10 mA.

IMPORTANT

1. Determine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage. Line voltage drop is calculated as follows:

Line voltage drop (V) = 3 x wire resistance (W/km) x wire length (m) x current (A) x 10 -3

2. Use a closed-loop connector (made by J.S.T. Mfg. Co., Ltd. or an equivalent) for the main circuit input and output terminals of Inverters of 200V 11 kW or more and those of 400V 22 kW or more.

Wiring the Main Circuits

This section describes wiring connections for the main circuit inputs and outputs.

Wiring Main Circuit Inputs

Observe the following precautions for wiring the main circuit power supply inputs.

Installing a Molded-case Circuit Breaker

Always connect the power input terminals (R, S, and T) and power supply via a molded-case circuit breaker

(MCCB) suitable for the Inverter.

• Choose an MCCB with a capacity of 1.5 to 2 times the Inverter's rated current.

•

For the MCCB's time characteristics, be sure to consider the Inverter's overload protection (one minute at

150% of the rated output current).

If the same MCCB is to be used for more than one Inverter, or other devices, set up a sequence so that the power supply will be turned OFF by a fault output, as shown in Fig 2.6

Fault output

(NC)

* For 400 V Class Inverters, connect a 400/200 V transformer.

Fig 2.6 MCCB Installation

Installing a Ground Fault Interrupter

Inverter outputs use high-speed switching, so high-frequency leakage current is generated. Therefore, at the

Inverter primary side, use a ground fault interrupter to detect only the leakage current in the frequency range that is hazardous to humans and exclude high-frequency leakage current.

•

For the special-purpose ground fault interrupter for Inverters, choose a ground fault interrupter with a sensitivity amperage of at least 30 mA per Inverter.

When using a general ground fault interrupter, choose a ground fault interrupter with a sensitivity amperage of 200 mA or more per Inverter and with an operating time of 0.1 s or more.

-16

Installing a Magnetic Contactor

If the power supply for the main circuit is to be shut off during a sequence, a magnetic contactor can be used.

When a magnetic contactor is installed on the primary side of the main circuit to forcibly stop the Inverter, however, the regenerative braking does not work and the Inverter will coast to a stop.

• The Inverter can be started and stopped by opening and closing the magnetic contactor on the primary side.

Frequently opening and closing the magnetic contactor, however, may cause the Inverter to break down.

Start and stop the Inverter at most once every 30 minutes.

•

When the Inverter is operated with the Digital Operator, automatic operation cannot be performed after recovery from a power interruption.

If the Braking Resistor Unit is used, program the sequence so that the magnetic contactor is turned OFF by the contact of the Unit's thermal overload relay.

Connecting Input Power Supply to the Terminal Block

Input power supply can be connected to any terminal R, S or T on the terminal block; the phase sequence of input power supply is irrelevant to the phase sequence.

Installing an AC Reactor or DC Reactor

If the Inverter is connected to a large-capacity power transformer (600 kW or more) or the phase advancing capacitor is switched, an excessive peak current may flow through the input power circuit, causing the converter unit to break down.

To prevent this, install an optional AC Reactor on the input side of the Inverter or a DC reactor to the DC reactor connection terminals.

This also improves the power factor on the power supply side.

Installing a Surge Absorber

Always use a surge absorber or diode for inductive loads near the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.

Installing a Noise Filter on Power Supply Side

Install a noise filter to eliminate noise transmitted between the power line and the Inverter.

• Correct Noise Filter Installation

Wiring the Output Side of Main Circuit

Observe the following precautions when wiring the main output circuits.

Connecting the Inverter and Motor

Connect output terminals U, V, and W to motor lead wires U, V, and W, respectively.

Check that the motor rotates forward with the Forward Run Command. Switch over any two of the output terminals to each other and reconnect if the motor rotates in reverse with the Forward Run Command.

Never Connect a Power Supply to Output Terminals

Never connect a power supply to output terminals U, V, and W. If voltage is applied to the output terminals, the internal circuits of the Inverter will be damaged.

Never Short or Ground Output Terminals

If the output terminals are touched with bare hands or the output wires come into contact with the Inverter casing, an electric shock or grounding will occur. This is extremely hazardous. Do not short the output wires.

Do Not Use a Phase Advancing Capacitor or Noise Filter

Never connect a phase advancing capacitor or LC/RC noise filter to an output circuit. The high-frequency components of the Inverter output may result in overheating or damage to these part or may result in damage to the Inverter or cause other parts to burn.

Precautions When Using an Electromagnetic Switch

Never connect an electromagnetic switch (MC) between the Inverter and motor and turn it ON or OFF during operation. If the MC is turned ON while the Inverter is operating, a large inrush current will be created and the overcurrent protection in the Inverter will operate.

-18

When using an MC to switch to a commercial power supply, stop the Inverter and motor before operating the

MC. Use the speed search function if the MC is operated during operation. If measures for momentary power interrupts are required, use a delayed release MC.

Installing a Thermal Overload Relay

This Inverter has an electronic thermal protection function to protect the motor from overheating. If, however, more than one motor is operated with one Inverter or a multi-polar motor is used, always install a thermal relay (THR) between the Inverter and the motor and set L1-01 to 0 (no motor protection). The sequence should be designed so that the contacts of the thermal overload relay turn OFF the magnetic contactor on the main circuit inputs.

Installing a Noise Filter on Output Side

Connect a noise filter to the output side of the Inverter to reduce radio noise and inductive noise.

Countermeasures Against Inductive Noise

As described previously, a noise filter can be used to prevent inductive noise from being generated on the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent inductive noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces inductive noise.

Countermeasures Against Radio Interference

Radio noise is generated from the Inverter as well as from the input and output lines. To reduce radio noise, install noise filters on both input and output sides, and also install the Inverter in a totally enclosed steel box.

The cable between the Inverter and the motor should be as short as possible.

Cable Length between Inverter and Motor

If the cable between the Inverter and the motor is long, the high-frequency leakage current will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust the carrier frequency (set in C6-01, C6-02) as shown in Table 2.6

. (For details, refer to Chapter 5 User Constants .)

Ground Wiring

Observe the following precautions when wiring the ground line.

•

Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100 Ω and that of the 400 V Inverter with a ground resistance of less than 10 Ω .

Do not share the ground wire with other devices, such as welding machines or power tools.

•

Always minimize the length of the ground wire.

Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.

When using more than one Inverter, be careful not to loop the ground wire.

Connecting the Braking Resistor (ERF)

A Braking Resistor that mounts to the Inverter can be used with 200 V and 400 V Class Inverters with outputs from 0.4 to 3.7 kW.

IMPORTANT

The braking resistor connection terminals are B1 and B2. Do not connect to any other terminals. Connecting to any terminals other than B1 or B2 can cause the resistor to overheat, resulting in damage to the equipment.

Connecting the Braking Resistor Unit (LKEB) and Braking Unit (CDBR)

Use the following settings if using a Braking Resistor Unit and Braking Unit.

A Braking Resistor that mounts to the Inverter can also be used with Inverters with outputs from 0.4 to 3.7

kW.

L8-01 is used when a braking resistor without thermal overload relay trip contacts (ERF type mounted to

Inverter) is connected.

The Braking Resistor Unit cannot be used and the deceleration time cannot be shortened by the Inverter if L3-

04 is set to 1 (i.e., if stall prevention is enabled for deceleration).

Wiring Main Circuit Terminals

To prevent the Unit from overheating, design the sequence to turn OFF the power supply for the thermal overload relay trip contacts of the Unit as shown in Fig 2.14

Control Circuit Wiring Precautions

Observe the following precautions when wiring control circuits.

• Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2,

•

Separate wiring for control circuit terminals MA, MB, MC, M1, and M2 (contact outputs) from wiring to other control circuit terminals.

Use shielded twisted-pair cables for control circuits to prevent operating faults. Process cable ends as shown in Fig 2.23

Connect the shield wire to terminal E (G).

Insulate the shield with tape to prevent contact with other signal lines and equipment.

Use a class 2 power supply (UL standard) when connecting to the control terminals.

Shield sheath Armor

Do not connect here.

Connect to shield sheath terminal at Inverter (terminal E

(G))

Insulate with tape

Wiring Method and Precautions

The wiring method is the same as the one used for straight solderless terminals. Refer to page 2-24. Observe the following precautions when wiring.

• Separate the control signal lines for the PG Speed Control Board from main circuit lines and power lines.

•

Connect the shield when connecting to a PG. The shield must be connected to prevent operational errors caused by noise. Also, do not use any lines that are more than 100 m long. Refer to Fig 2.23

for details on connecting the shield.

Connect the shield to the shield terminal (E).

Do not solder the ends of wires. Doing so may cause contact faults.

When not using straight solderless terminals, strip the wires to a length of approximately 5.5 mm.

Quick programming mode

Table 3.2 Modes

Primary function(s)

The Inverter can be run in this mode.

Use this mode when monitoring values such as frequency references or output current, displaying fault information, or displaying the fault history.

Use this mode to reference and set the minimum user constants to operate the

Inverter (e.g., the operating environment of the Inverter and Digital Operator).

Use this mode to reference and set all user constants.

Advanced programming mode

Autotuning Mode

Autotuning automatically tunes and sets the required motor constants when operating in the vector control method. Always perform autotuning before starting operation.

When V/f control has been selected, stationary autotuning for only line-to-line resistance can be selected.

When the motor cannot be disconnected from the load, perform stationary autotuning. Contact your Yaskawa representatives to set motor constants by calculation.

The Inverter's autotuning function automatically determines the motor constants, while a servo system's autotuning function determines the size of a load, so these autotuning functions are fundamentally different.

The factory setting of the Inverter is A1-02 = 0 for V/f control.

Example of Operation

Set the motor output power (in kW), rated voltage, rated current, rated frequency, rated speed, and number of poles specified on the nameplate on the motor and then press the RUN Key. The motor is automatically run and the motor constants measured based on these settings and autotuning will be set.

Always set the above items. Autotuning cannot be started otherwise, e.g., it cannot be started from the motor rated voltage display.

DATA/ENTER Key is pressed after changing the setting.

Trial Operation Procedures

The procedure for the trial operate is described in order in this section.

Application Confirmation

First, confirm the application before using the Inverter.

• Fan, blower, pump

• Other equipment

For any Inverter application other than a fan, blower, or pump, set C6-01 (CT/VT Selection) to 0 (CT: low carrier, constant torque). The default setting is 1 (VT: high carrier, variable torque) for Inverters with SPEC: C or earlier and 0 (CT: low carrier, constant torque) for Inverters with SPEC: E or later.

However, only 1(VT) can be set for 200 V Class 110 kW as well as 400 V Class 220 kW and 300 kW Inverters with any SPEC.

Setting the Power Supply Voltage Jumper (400 V Class Inverters of 75 kW or Higher)

Set the power supply voltage jumper after setting E1-01 (Input Voltage Setting) for 400 V Class Inverters of 75 kW or higher. Insert the jumper into the power tap nearest to the actual power supply voltage.

The jumper is factory-set to 440 V when shipped. If the power supply voltage is not 440 V, use the following procedure to change the setting.

1. Turn OFF the power supply and wait for at least 5 minutes.

2. Confirm that the CHARGE indicator has gone out.

3. Remove the terminal cover.

4. Insert the jumper at the position for the voltage supplied to the Inverter (see Fig 4.2

5. Return the terminal cover to its original position.

Use the following procedure to perform autotuning if using the vector control method or the cable length is long, etc. Motor constants will be set automatically.

If the control method was changed after autotuning, be sure to perform autotuning again.

One of the following four autotuning modes can be set.

• Rotational autotuning

Stationary autotuning for line-to-line resistance only

• Stationary autotuning 2

Precautions Before Using Autotuning

Read the following precautions before using autotuning.

• Autotuning the Inverter is fundamentally different from autotuning the servo system. Inverter autotuning automatically adjusts parameters according to detected motor constants, whereas servo system autotuning adjusts parameters according to the detected size of the load.

• When speed or torque precision is required at high speeds (i.e., 90% of the rated speed or higher), use a motor with a rated voltage that is 20 V less than the input power supply voltage of the Inverter for 200Vclass Inverters and 40 V less for 400V-class Inverters. If the rated voltage of the motor is the same as the input power supply voltage, the voltage output from the Inverter will be unstable at high speeds and sufficient performance will not be possible.

•

Use stationary autotuning 1 or 2 whenever performing autotuning for a motor that is connected to a load.

Use rotational autotuning whenever performing autotuning for a motor that has fixed output characteristics, when high precision is required, or for a motor that is not connected to a load.

If rotational autotuning is performed for a motor connected to a load, the motor constants will not be found accurately and the motor may exhibit abnormal operation. Never perform rotational autotuning for a motor connected to a load.

If the wiring between the Inverter and motor changes by 50 m or more between autotuning and motor installation, perform stationary autotuning for line-to-line resistance only.

•

If the motor cable is long (50 m or longer), perform stationary autotuning for line-to-line resistance only even when using V/f control.

The status of the multi-function inputs and multi-function outputs will be as shown in the following table during autotuning. When performing autotuning with the motor connected to a load, be sure that the holding brake is not applied during autotuning, especially for conveyor systems or similar equipment.

To cancel autotuning, always use the STOP Key on the Digital Operator.

Power will be supplied to the motor when stationary autotuning is performed even though the motor will not turn. Do not touch the motor until autotuning has been completed.

Setting the Autotuning Mode

Rotational Autotuning (T1-01 = 0)

Rotational autotuning is used for open-loop vector control and flux vector control. Set T1-01 to 0, input the data from the nameplate, and then press the RUN Key on the Digital Operator. The Inverter will stop the motor for approximately 1 minute and then set the required motor constants automatically while operating the motor for approximately 1 minute.

IMPORTANT

1. Always disconnect the motor from the machine and confirm that it is safe to operate the motor before performing rotational autotuning.

2. If the motor cannot be operated by itself, perform stationary autotuning, but always use rotational autotuning whenever it is possible to operate the motor by itself to increase performance.

Stationary Autotuning 1 (T1-01 = 1)

Stationary autotuning1 is used for open-loop vector control and flux vector control. Set T1-01 to 1, input the data from the nameplate, and then press the RUN Key on the Digital Operator. The Inverter will supply power to the stationary motor for approximately 1 minute and some of the motor constants will be set automatically.

The remaining motor constants E2-02 (motor rated slip) and E2-03 (motor no-load current) will be set automatically the first time operation is started in drive mode. To perform an operation immediately after stationary autotuning1, use the following procedure under the recommended conditions.

1. Check the values of E2-02 and E2-03 in verify mode or advanced programming mode.

2. Run the motor once in drive mode under the following conditions.

•

The Inverter and the motor are connected.

The motor shaft is not locked with a mechanical brake or other stopping mechanism (or function).

•

A motor-load ratio of 30 % or less is maintained.

A speed of 30 % or more of the base frequency set at E1-06 (default = highest frequency) is maintained at a constant speed for one second or more.

3. After stopping the motor, check the values of E2-02 and E2-03 again in verify mode or advanced programming mode. If the values of E2-02 and E2-03 differ from the ones before the first operation was carried out, the settings have been successfully completed. Next, check if the values are suitable or not.

Trial Operation Procedures

If the values of E2-02 and E2-03 differed greatly from the reference data of the motor in the test report or the instruction manual, hunting, motor vibrations, insufficient motor torque, or an overcurrent may occur because the motor is operated although the aforementioned conditions have not been fulfilled after stationary autotuning1. For elevators, failure to observe this caution may result in the cage falling or injury. If so, perform stationary autotuning1 again and run the motor using the aforementioned procedure under the recommended conditions or perform stationary autotuning 2 or rotational autotuning.

Usually the standard setting for E2-02 is 1 Hz to 3 Hz, and that for E2-03 is 30% to 65% of the rated current for a general-purpose motor. Generally, the larger the motor capacity is, the smaller the rated slip and the ratio of the no-load current to the rated current become. Use the data given in Factory Settings that Change with the Inverter Capacity (o2-04) of Chapter 5 User Constants as a reference.

IMPORTANT

1. Power will be supplied to the motor when stationary autotuning 1 is performed even though the motor will not turn. Do not touch the motor until autotuning has been completed.

2. When performing stationary autotuning 1 connected to a conveyor or other machine, ensure that the holding brake is not activated during autotuning.

Stationary Autotuning for Line-to-Line Resistance Only (T1-01 = 2)

Stationary autotuning for line-to-line resistance only can be used in any control method. This is the only autotuning possible for V/f control and V/f control with PG modes.

Autotuning can be used to prevent control errors when the motor cable is long (50 m or longer) or the cable length has changed since installation or when the motor and Inverter have different capacities.

Set T1-01 to 2, and then press the RUN Key on the Digital Operator. The Inverter will supply power to the stationary motor for approximately 20 seconds and the Motor Line-to-Line Resistance (E2-05) and cable resistance will be automatically measured.

IMPORTANT

1. Power will be supplied to the motor when stationary autotuning for line-to-line resistance is performed even though the motor will not turn. Do not touch the motor until autotuning has been completed.

2. When performing stationary autotuning connected to a conveyor or other machine, ensure that the holding brake is not activated during autotuning.

Stationary Autotuning 2 (T1-01 = 4)

Stationary autotuning 2 is used for open-loop vector control and flux vector control. Set T1-04 to 4, and Motor no-load current (T1-09) will be added as a setting item. Input the data from the nameplate. Be sure to input the value or motor no-load current (motor exciting current) from motor examination results to T1-09. After autotuning, the value of T1-09 will be written in E1-03. When not setting T1-09, the value of Yaskawa standard motor’s no-load current will be written in E1-03.

IMPORTANT

1. Power will be supplied to the motor when stationary autotuning 2 is performed even though the motor will not turn. Do not touch the motor until autotuning has been completed.

2. When performing stationary autotuning 2 connected to a conveyor or other machine, ensure that the holding brake is not activated during autotuning.

Precautions for Rotational and Stationary Autotuning

Lower the base voltage based on Fig 4.4

to prevent saturation of the Inverter’s output voltage when the rated voltage of the motor is higher than the voltage of the power supply to the Inverter. Use the following procedure to perform autotuning.

1. Input the voltage of the input power supply to T1-03 (Motor rated voltage).

2. Input the results of the following formula to T1-05 (Motor base frequency):

(Base frequency from the motor’s nameplate × setting of T1-03)/(Rated voltage from motor’s nameplate)

3. Perform autotuning.

After having completed autotuning, set E1-05 (Motor maximum frequency) to the base frequency shown on the motor nameplate.

IMPORTANT

1. When speed precision is required at high speeds (i.e., 90% of the rated speed or higher), set T1-03 (Motor rated voltage) to the input power supply voltage × 0.9.

2. When operating at high speeds (i.e., 90% of the rated speed or higher), the output current will increase as the input power supply voltage is reduced. Be sure to provide sufficient margin in the Inverter current.

Precautions after Using Rotational and Stationary Autotuning

After completing autotuning, set E1-04 (Max. output frequency) to the base frequency from the motor’s nameplate.

In stationary autotuning1, when the motor is first operated in the drive mode after tuning, the remaining motor constants E2-02 (Motor rated slip) and E2-03 (Motor no-load current) are set automatically. To perform an operation immediately after stationary autotuning 1, use the following procedure under the recommended conditions.

1. Check the values of E2-02 and E2-03 in verify mode or advanced programming mode.

2. Run the motor once in drive mode under the following conditions.

•

The Inverter and the motor are connected.

The motor shaft is not locked with a mechanical brake or other stopping mechanism (or function).

•

A motor-load ratio of 30 % or less is maintained.

A speed of 30 % or more of the base frequency set at E1-06 (default = highest frequency) is maintained at a constant speed for one second or more.

If the values of E2-02 and E2-03 differed greatly from the reference data of the motor in the test report or the instruction manual, hunting, motor vibrations, insufficient motor torque, or an overcurrent may occur because the motor is operated although the aforementioned conditions have not been fulfilled after stationary autotuning 1. For elevators, failure to observe this caution may result in the cage falling or injury. If so, perform stationary autotuning 1 again and run the motor using the aforementioned procedure under the recommended conditions or perform stationary autotuning 2 or rotational autotuning.

Usually the standard setting for E2-02 is 1Hz to 3Hz, and that for E2-03 is 30% to 65% of the rated current for a general-purpose motor. Generally, the larger the motor capacity is, the smaller the rated slip and the ratio of the no-load current to the rated current become. Use the data given in Factory Settings that

Change with the Inverter Capacity (o2-04) of Chapter 5 User Constants as a reference.

Trial Operation Procedures

Precautions After Using Autotuning

For a fixed output region, the V/f pattern for the maximum point in the output region must be set after completing autotuning. To increase the motor’s rated speed by 1 to 1.2 times or when using a fixed output motor, make the following changes after autotuning. Do not change E1-06 (Base frequency) or E1-13 (Base voltage).

Increasing the Motor’s Rated Speed by 1 to 1.2 Times

To increase the motor’s rated speed by 1 to 1.2 times, use the following formula to change the setting of E1-04

(Maximum output frequency):

E1-04 = (Motor’s rated speed) × (No. of motor poles)/120 (Hz) × (1 to 1.2)

If the motor’s speed is increased beyond the rated speed, fixed output characteristics will be used at high speeds and motor torque will be reduced.

Applications to Constant Output Motors Such as Motors for Machine Tools

Use the following formula to change the settings of E1-04 (Maximum output frequency) and E1-05 (Maximum frequency) when using a motor with a fixed output, e.g., a motor for a machine tool:

E1-04 = Frequency (Hz) at maximum speed under no-load conditions (load rate = 0)

E1-05 = Voltage (V) at maximum speed under no-load conditions (load rate = 0)

Do not change the E2 motor constants after performing autotuning.

Precautions for Precision Settings

Application Settings

User constants are set as required in advanced programming mode (i.e., with the ADV indicator lit on the Digital Operator). All the constants that can be set in quick programming mode can also be displayed and set in advanced programming mode.

Setting Examples

The following are examples of settings for applications.

• When using an Inverter-mounted braking resistor (ERF), set L8-01 to 1 to enable ERF braking resistor overheating protection.

•

To prevent the machine from being operated in reverse, set b1-04 to 1 to disable reverse operation.

To increase the speed of a 60 Hz motor by 10%, set E1-04 to 66.0 Hz.

•

To use a 0 to 10-V analog signal for a 60 Hz motor for variable-speed operation between 0 and 54 Hz (0% to 90% speed deduction), set H3-02 to 90.0%.

To control speed between 20% and 80% to ensure smooth gear operation and limit the maximum speed of the machine, set d2-01 to 80.0% and set d2-02 to 20.0%.

No-load Operation

To being no-load operation (without connecting the machine and the motor), press the LOCAL/REMOTE Key on the Digital Operator to change to LOCAL mode (the SEQ and REF indicators on the Digital Operator should be OFF).

Always confirm safety around the motor and machine before starting Inverter operation from the Digital

Operator. Confirm that the motor works normally and that no errors are displayed at the Inverter.

Jog Frequency Reference (d1-17, default: 6.00 Hz) can be started and stopped by pressing and releasing the

JOG Key on the Digital Operator. If the external sequence prevent operation from the Digital Operator, confirm that emergency stop circuits and machine safety mechanisms are functioning, and then start operation in

REMOTE mode (i.e., with a signal from the control signal terminals). The safety precautions must always be taken before starting the Inverter with the motor connected to the machine.

Both a Run Command (forward or reverse) and a frequency reference (or multi-step speed reference) must be provided to start Inverter operation.

Input these commands and reference regardless of the operation method (i.e., LOCAL of REMOTE).

INFO

Loaded Operation

Connect the machine to the motor and then start operation as described for no-load operation (i.e., from the

Digital Operator or by using control circuit terminal signals).

Connecting the Load

•

After confirming that the motor has stopped completely, connect the mechanical system.

Be sure to tighten all the screws when securing the motor shaft to the mechanical system.

Trial Operation Procedures

Operation using the Digital Operator

•

Use the Digital Operator to start operation in LOCAL mode in the same way as in no-load operation.

If fault occurs during operation, make sure the STOP Key on the Digital Operator is easily accessible.

At first, set the frequency reference to a low speed of one tenth the normal operating speed.

Checking Operating Status

•

Having checked that the operating direction is correct and that the machine is operating smoothly at slow speed, increase the frequency reference.

After changing the frequency reference or the rotation direction, check that there is no oscillation or abnormal sound from the motor. Check the monitor display to ensure that U1-03 (Output Current) is not too high.

Refer to Adjustment Suggestions on page 4-18 if hunting, vibration, or other problems originating in the control system occur.

Check and Recording User Constants

Use verify mode (i.e., when the VERIFY indicator on the Digital Operator is lit) to check user constants that have been changed for trial operation and record them in a user constant table.

Any user constants that have been change by autotuning will also be displayed in verify mode.

If required, the copy function in constants o3-01 and o3-02 displayed in advanced programming mode can be used to copy the changed settings from the Inverter to a recording area in the Digital Operator. If changed settings are saved in the Digital Operator, they can be easily copied back to the Inverter to speed up system recovery if for any reason the Inverter has to be replaced.

The following functions can also be used to manage user constants.

• Recording user constants

•

Setting access levels for user constants

Setting a password

Recording User Constants (o2-03)

If o2-03 is set to 1 after completing trial operation, the settings of user constants will be saved in a separate memory area in the Inverter. Later, after Inverter settings have been changed, the user constants can be initialized to the settings saved in the separate memory area when o2-03 was set to 1 by setting A1-03 (Initialize) to

1110.

User Constant Access Levels (A1-01)

A1-01 can be set to 0 (monitoring-only) to prevent user constants from being changed. A1-01 can also be set to 1 (User-specified Constants) and used along with A2 constants to display only constants required by the machine or application in a programming mode.

Password (A1-04 and A1-05)

When the access level is set to monitoring-only (A1-01 = 0), a password can be set so that user constants will be displayed only when the correct password is input.

Adjustment Method

• Increase the setting if motor magnetic noise is high.

• Reduce the setting if hunting or vibration occurs at low speeds.

• Increase the setting if torque or speed response is slow.

• Reduce the setting if shock at startup is large.

• Increase the setting (by increments of 5) if torque or speed response is slow.

• Reduce the setting if hunting or vibration occurs.

• Reduce the setting if torque or speed response is slow.

• Increase the setting if hunting or vibration occurs.

Set the output frequency at which to change the ASR proportional gain and integral time when the same values cannot be used for both high-speed and low-speed operation.

• Reduce the setting (by increments of 0.01) if torque or speed response is show.

• Increase the setting if machine rigidity is low and the system vibrates easily.

• Increase the setting if motor magnetic noise is high.

• Reduce the setting if hunting or vibration occurs at low to middle-range speeds.

* The setting is given for 200 V Class Inverters. Double the voltage for 400 V Class Inverters.

•

Do not change the Torque Compensation Gain (C4-01) from its default setting of 1.00 when using openloop vector control.

If speeds are inaccurate during regeneration in open-loop vector control, enable Slip Compensation During

Regeneration (C3-04 = 1).

Use slip compensation to improve speed control during V/f control (A1-02 = 0).

Set the Motor Rated Current (E2-01), Motor Rated Slip (E2-02), and Motor No-load Current (E2-03), and then adjust the Slip Compensation Gain (C3-01) to between 0.5 and 1.5. The default setting for V/f control is C3-01 = 0.0 (slip compensation disabled).

-20

• To improve speed response and stability in V/f control with a PG (A1-02 = 1), set the ASR constants (C5-

01 to C5-05) to between 0.5 and 1.5 times the default. (It is not normally necessary to adjust this setting.)

ASR for V/f control with a PG will only control the output frequency; a high gain, such as is possible for open-loop vector control, cannot be set.

The following user constants will also indirectly affect the control system.

CT/VT selection (C6-01)

Application

Sets the maximum torque and overload capability to 120% or 150%.

DWELL function (b6-01 to b6-04)

Droop function (b7-01 to b7-02)

Used for heavy loads or large machine backlashes.

Used to soften the torque or to balance the load between two motors. Can be used when the control method (A1-02) is set to 3.

Acceleration/deceleration times

(C1-01 to C1-11)

S-curve characteristics (C2-01 to C2-04)

Jump frequencies (d3-01 to d3-04)

Analog input filter time constant (H3-12)

Adjust torque during acceleration and deceleration.

Used to prevent shock when completing acceleration.

Used to avoid resonance points during operation.

Used to prevent fluctuations in analog input signals caused by noise.

Stall prevention (L3-01 to L3-06,

L3-11, L3-12 )

Torque limits (L7-01 to L7-04,

L7-06, L7-07 )

Feed forward control (N5-01 to N5-04)

Used to prevent 0 V (overvoltage errors) and motor stalling for heavy loads or rapid acceleration/deceleration. Stall prevention is enabled by default and the setting does not normally need to be changed. When using a braking resistor, however, disable stall prevention during deceleration by setting L3-04 to 0.

Set the maximum torque during vector control. If a setting is increased, use a motor with higher capacity than the Inverter. If a setting is reduced, stalling can occur under heavy loads.

Used to increase response for acceleration/deceleration or to reduce overshooting when there is low machine rigidity and the gain of the speed controller (ASR) cannot be increased. The inertia ratio between the load and motor and the acceleration time of the motor running alone must be set.

Normally, there is no need to make this setting.

Make the adjustments as follows:

• If vibration occurs with light load, increase the setting.

• If the motor stalls, reduce the setting.

If the setting is too large, the voltage will be too suppressed and the motor may stall.

CT: Low Carrier, Constant Torque

Constant Torque

VT: High Carrier, Variable Torque

Variable Torque

Torque Torque

0 Motor speed

Motor speed

Constant torque means a constant load torque for all motor speed, and it requires overload resistance capability. Applications include pushers, conveyors, cranes, and other friction or heavy loads.

Variable torque means that the load torque will decrease as the speed decreases. Normally, overload resistance capability is not required. Applications include fans and pumps.

Low carrier: Electromagnetic noise is present.

High carrier: Electromagnetic noise is not present.

Carrier Frequency

When selecting the carrier frequency, observe the following precautions items.

• When using a device with C6-01 set to 1 (VT), adjust the carrier frequency according to the cases shown below.

If the wiring distance between Inverter and motor is long: Set the carrier frequency low. (Use the following values as guidelines.

Wiring Length 50 m or less 100 m or less Over 100 m

C6-02 (carrier frequency) setting

0 to 6 (15 kHz) 0 to 4 (10 kHz) 0 to 2 (5 kHz)

If speed and torque are inconsistent at low speeds: Set the carrier frequency low.

If Inverter noise is affecting peripheral devices: Set the carrier frequency low.

If leakage current from the Inverter is large: Set the carrier frequency low.

If metallic noise from the motor is large: Set the carrier frequency high.

Carrier frequency upper limit depends on the Inverter capacity. Refer to Factory Settings that Change with the

Inverter Capacity (o2-04) on page 5-83.

• When using V/f control or V/f control with PG, you can vary the carrier frequency to match the output frequency, as shown in the following diagram, by setting C6-03 (Carrier Frequency Upper Limit), C6-04

(Carrier Frequency Lower Limit), and C6-05 (Carrier Frequency Proportional Gain).

With vector control, the carrier frequency is fixed by the Carrier Frequency Upper Limit in C6-03 if userset, or by the carrier frequency set in C6-02.

To fix the carrier frequency, set C6-03 and C6-04 to the same value, or set C6-05 to 0.

If the settings are as shown below, OPE11 (Data setting error) will occur.

If Carrier Frequency Proportional Gain (C6-05) > 6 and C6-03 < C6-04.

Performing Operations Using Control Circuit Terminals

When b1-02 is set to 1, you can perform Inverter operations using the control circuit terminals.

Performing Operations Using a 2-wire Sequence

The factory setting is set to a 2-wire sequence. When control circuit terminal S1 is set to ON, forward operation will be performed, and when S1 is turned OFF, the Inverter will stop. In the same way, when control circuit terminal S2 is set to ON, reverse operation will be performed, and when S2 is turned OFF, the Inverter will stop.

Stopping Methods

Deceleration to Stop

If the Stop Command is input (i.e., the Run Command is turned OFF) when b1-03 is set to 0, the motor decelerates to a stop according to the deceleration time that has been set. (Factory setting: C1-02 (Deceleration

Time 1))

If the output frequency when decelerating to a stop falls below b2-01, the DC injection brake will be applied using the DC current set in b2-02 only for the time set in b2-04.

For deceleration time settings, refer to page 6-25 Setting Acceleration and Deceleration Times .

Setting Precautions

• When using flux vector control, the zero-speed control starts when motor speed drops to b2-01 during deceleration. Also, the setting b2-01 < E1-09 is possible.

• The current level during injection brake time at start is the value of E2-03 (motor no-load current). Accordingly, b2-02 is invalid in flux vector control.

Stopping Methods

Coast to Stop

If the Stop Command is input (i.e., the Run Command is turned OFF) when b1-03 is set to 1, the Inverter output voltage is interrupted. The motor coasts to a stop at the deceleration rate that counterbalances damage to the machine and inertia including the load.

DC Braking Stop

If the Stop Command is input (i.e., the Run Command is turned OFF) when b1-03 is set to 2, a wait is made for the time set in L2-03 (Minimum Baseblock (BB) Time) and then the DC injection brake current set in b2-

02 is sent to the motor to apply a DC injection brake to stop the motor. The DC injection brake time is determined by the set value in b2-04 and the output frequency when the Stop Command is input.

Using an Emergency Stop

Set a multi-function input terminal (H1 ) to 15 or 17 (emergency stop) to decelerate to a stop at the deceleration time set in C1-09. If inputting the emergency stop with an NO contact, set the multi-function input terminal (H1 ) to 15, and if inputting the emergency stop with an NC contact, set the multi-function input terminal (H1 ) to 17.

After the emergency Stop Command has been input, operation cannot be restarted until the Inverter has stopped. To cancel the emergency stop, turn OFF the Run Command and emergency Stop Command.

Adjusting Acceleration and Deceleration Time Using an Analog Input

If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function

Analog Input Terminal A3 Function Selection) to 5 (acceleration/deceleration time gain), you can adjust the acceleration/deceleration time using terminal A2's or A3's input voltage.

The Inverter's acceleration time when the acceleration time has been set in C1-01 is as follows:

Acceleration time = C1-01 set value x acceleration/deceleration time gain

Entering S-curve Characteristics in the Acceleration and Deceleration Time

By performing acceleration and deceleration using an S-curve pattern, you can reduce shock when starting and stopping the machine.

Using the Inverter, you can set an S-curve characteristic time for each of the following: Acceleration start time, deceleration start time, acceleration end time, and deceleration end time.

INFO

Set the S-curve characteristic time to lengthen acceleration/deceleration time as follows:

Acceleration time = Selected acceleration time + (Acceleration start time S-curve characteristic time +

Acceleration end time S-curve characteristic time) / 2

Deceleration time = Selected deceleration time + (Deceleration start time S-curve characteristic time +

Deceleration end time S-curve characteristic time) / 2

Preventing the Motor from Stalling During Acceleration (Stall Prevention

During Acceleration Function)

The Stall Prevention During Acceleration function prevents the motor from stalling if a heavy load is placed on the motor, or sudden rapid acceleration is performed.

If you set L3-01 to 1 (enabled) and the Inverter output current exceeds the -15% level of the set value in L3-

02, the acceleration rate will begin to slow down. When L3-02 is exceeded, acceleration will stop.

If you set L3-01 to 2 (optimum adjustment), the motor current accelerates to the value set in L3-02. With this setting, the acceleration time setting is ignored.

Setting Precautions

•

If the motor capacity is small compared to the Inverter capacity, or if the motor is operated using the factory settings, resulting in the motor stalling, lower the set value of L3-02.

If using the motor in the constant output range, L3-02 will be automatically lowered to prevent stalling.

L3-03 is the limit value to prevent the stall prevention level in the constant output range from being reduced more than necessary.

Set the constants as a percent taking the Inverter rated voltage to be 100%.

Preventing Overvoltage During Deceleration (Stall Prevention During

Deceleration Function)

The Stall Prevention During Deceleration function makes the rate of deceleration more gentle to suppress increases in DC bus voltage when the DC bus voltage exceeds the set value during motor deceleration.

This function automatically lengthens the deceleration time with respect to the bus voltage, even if the deceleration time has been set to a considerably small value.

If L3-04 is set to 1 or 2, when the main circuit DC voltage approaches the stall prevention level during deceleration, deceleration stops, and when deceleration falls below the level, is restarted. Using this operation, deceleration time is automatically lengthened. If L3-04 is set to 1, deceleration time returns to the set value, and if L3-04 is set to 2, deceleration is automatically adjusted to a faster deceleration time within the range of the stall prevention level during deceleration.

•

When using the braking option (braking resistor, Braking Resistor Units, and Braking Units), be sure to set constant L3-04 to 0 or 3.

To decelerate at a shorter time than the deceleration time set when L3-04 is set to 0 with the braking option enabled, set L3-04 to 3.

• The setting of L3-04 is ignored for flux vector control.

Preventing Overvoltage by Automatically Reducing the Regenerative

Torque Limit (Overvoltage Inhibit Function, SPEC: E or later only)

The overvoltage inhibit function is a function that, by reducing the regenerative torque limit to a value less than its set value according to the main circuit voltage level, suppresses voltage rises with regenerative torque.

Using this function means that if, for example, the main circuit voltage rises during deceleration, the regenerative torque limit will be reduced and so the deceleration rate will be reduced automatically, suppressing rises in the main circuit voltage.

This function is effective for suppressing overvoltages that occur during stabilization after an overshoot following sudden acceleration. This function differs from the stall prevention during deceleration function in this respect.

This function is enabled during vector control.

Setting Precautions

When this function is enabled, if the main circuit voltage rises, the regenerative torque limit will decrease to a value less than its set value and so the motor will not rotate at the speed specified by the speed reference.

Therefore, in applications where it is necessary to rotate the motor at the speed specified by the speed reference, disable this function and use a converter, a dynamic braking resistor, or a power regenerative unit to suppress rises in the main circuit voltage.

Limiting Minimum Frequency

If you do not want the motor to rotate at below a given frequency, use constants d2-02 or d2-03.

There are two methods of limiting the minimum frequency, as follows:

• Adjust the minimum level for all frequencies.

• Adjust the minimum level for the master speed frequency (i.e., the lower levels of the jog frequency, multistep speed frequency, and auxiliary frequency will not be adjusted).

Improved Operating Efficiency

This section explains functions for improving motor operating efficiency.

Reducing Motor Speed Fluctuation (Slip Compensation Function)

When the load is large, the amount of motor slip also grows large and the motor speed decreases. The slip compensation function controls the motor at a constant speed, regardless of changes in load. When the motor is operating at the rated load, constant E2-02 (Motor Rated Slip) × the frequency in constant C3-01 is added to the output frequency.

Adjusting Slip Compensation Gain

You can switch the C3-01 constant settings as shown below by changing the control method.

• V/f control: 0.0

• Open-loop vector control: 1.0

• Flux vector control: 1.0

Set C3-01 to 1.0 to compensate the rated slip set using the rated torque output status.

Adjust the slip compensation gain using the following procedure.

1. Set E2-02 (Motor Rated Slip) and E2-03 (Motor No-load Current) correctly.

You can calculate the motor rated slip from the values on the motor nameplate using the following formula.

Amount of motor rated slip (Hz) = Motor rated frequency (Hz) - No. of rated rotations (min

− 1

.) × No. of motor poles / 120

Set the values for rated voltage, rated frequency, and no-load current in the motor unladen current. The motor rated slip is set automatically in the vector control using autotuning.

2. In V/f control, set C3-01 to 1.0. Setting this constant to 0.0 disables slip compensation.

3. Apply a load, and measure the speed to adjust the slip compensation gain. Adjust the slip compensation gain by 0.1 at a time. If the speed is less than the target value, increase the slip compensation gain, and if the speed is greater than the target value, reduce the slip compensation gain.

For flux vector control, the slip compensation gain is used as the motor temperature compensation gain. When the motor temperate increases, the motor’s internal constant increases, resulting in an increase in slip. If C3-01 is set, the amount of slip is adjusted as the temperature rises. Set C3-01 if the amount of torque varies with the temperature when using torque control or a torque limit. The larger the value of C3-01, the larger the compensation.

Adjusting Slip Compensation Primary Delay Time Constant

Set the slip compensation primary delay time constant in ms.

You can switch the factory settings as follows by changing the control method.

• V/f control: 2000 ms

• Open-loop vector control: 200 ms

Normally, there is no need to make these settings. When the slip compensation response is low, lower the set value. When the speed is unstable, increase the set value.

Adjusting Slip Compensation Limit

The upper limit for the slip compensation amount can be set in C3-03 as a percent, taking the motor rated slip amount as 100%.

If the speed is lower than the target value but does not change even when you adjust the slip compensation gain, the motor may have reached the slip compensation limit. Increase the limit, and check the speed again.

Make the settings, however, to make sure that the value of the slip compensation limit and reference frequency does not exceed the tolerance of the machine.

The following diagram shows the slip compensation limit for the constant torque range and fixed output range.

Fig 6.35 Slip Compensation Limit

Selecting Slip Compensation Function During Regeneration

Whether to enable or disable the slip compensation function during regeneration can be set in C3-04.

If the slip compensation function operates during regeneration, you might have to use the braking option

(braking resistor, Braking Resistor Unit, and Braking Unit) to momentarily increase the regenerative amount.

Selecting Output Voltage Limit Operation

If output voltage saturation occurs while the output voltage limit operation is disabled, the output current will not change, but torque control accuracy will be lost. If torque control accuracy is required, set C3-05 to 1 to enable the output voltage limit operation.

If the output voltage limit operation is enabled, motor magnetic flux current is controlled automatically, and torque control accuracy is maintained to limit the output voltage references. Consequently, the output current will increase by approximately 10% maximum (with rated load) compared with when the output voltage limit operation is disabled, so check the Inverter current margin.

Setting Precautions

• If using the device at medium to low speed only, if the power supply voltage is 10% or more higher than the motor rated voltage, or if the torque control accuracy at high speeds is insufficient, it is not necessary to change the output voltage limit operation.

• If the power supply voltage is too low compared with the motor rated voltage, torque control accuracy may be lost even if the output voltage limit operation is enabled.

Compensating for Insufficient Torque at Startup and Low-speed Operation (Torque Compensation)

The torque compensation function detects that the motor load has increased, and increases the output torque.

V/f control calculates and adjusts the motor primary loss voltage according to the output voltage (V), and compensates for insufficient torque at startup and during low-speed operation. Calculate the compensation voltage as follows: Motor primary voltage loss × constant C4-01.

Vector control separates the motor excitation current and the torque current by calculating the motor primary current, and controlling each of the two separately.

Calculate the torque current as follows: Calculated torque reference × C4-01

Selecting the Control Method for Torque Limit during Acceleration and Deceleration

(SPEC: E or later only)

L7-07 is used to select the control method for the torque limit during acceleration and deceleration. The selections are proportional control and integral control. For applications, in which the torque limit will be reached during acceleration and deceleration, torque control can be given priority by selecting integral control. To increase the change in frequency for the torque limit when integral control is selected, decrease the value set for L7-06 (Integral Time Setting for Torque Limit).

Setting Precautions

•

When the torque limit function is operating, control and compensation of the motor speed is disabled because torque control is given priority. Therefore, the acceleration and deceleration times may increase or the number of motor rotations may decrease.

When using the torque limit to raise and lower loads, do not carelessly lower the torque limit value, as this may result in the motor falling or slipping.

Torque limits using an analog input are the upper limit value (during 10 V or 20 mA input) of 100% of the motor rated torque. To make the torque limit value during 10 V or 20 mA input 150% of the rated torque, set the input terminal gain to 150.0 (%). Adjust the gain for multi-function analog input terminal A2 using

H3-10 and for multi-function analog input terminal A3 using H3-06.

•

The torque limit accuracy is ±5% at the output frequency of 10 Hz or above. When output frequency is less than 10 Hz, accuracy is lowered.

When the torque is limited while L7-07 is set to 1 (integral control), the acceleration and deceleration times may increase or the motor speed may not agree with the speed reference value.

Preventing Motor Stalling During Operation

Stall prevention during operation prevents the motor from stalling by automatically lowering the Inverter's output frequency when a transient overload occurs while the motor is operating at a constant speed.

Stall prevention during operation is enabled only during V/f control. If the Inverter output current continues to exceed the setting in constant L3-06 for 100 ms or longer, the motor speed is reduced. Set whether to enable or disable deceleration time using constant L3-05. Set the deceleration time using C1-02 (Acceleration time 1) or

C1-04 (Acceleration Time 2).

If the Inverter output current reaches the set value in L3-06 - 2% (Inverter Rated Output Current), the motor will accelerate again at the frequency set or the acceleration time set.

Detecting Motor Torque

If an excessive load is placed on the machinery (overtorque) or the load is suddenly lightened (undertorque), you can output an alarm signal to multi-function output terminal M1-M2, P1-PC, or P2-PC.

To use the overtorque/undertorque detection function, set B, 17, 18, 19 (overtorque/undertorque detection NO/

NC) in one of the following constants: H2-01 to H2-03 (multi-function output terminals M1-M2, P1-PC, and

P2-PC function selection).

The overtorque/undertorque detection level is the current level (Inverter rated output current 100%) in V/f control, and the motor torque (motor rated torque 100%) in vector control.

Setting Precautions

• If multiple motors are connected to one Inverter, set constant L1-01 to 0 (disabled). To protect the motor, install a thermal relay in the motor power cable, and perform overload protection on each motor.

• With applications where the power supply is often turned ON and OFF, there is a risk that the circuit cannot be protected even if this constant has been set to 1 (enabled), because the thermal value will be reset.

• To detect overloads in good time, set the set value in constant L1-02 to a low setting.

• When using a general-purpose motor (standard motor), the cooling ability will be lowered by f 1/4 (frequency). Consequently, the frequency may cause motor overload protection (OL1) to occur, even below the rated current. If operating using the rated current at a low frequency, use a special motor.

Machine Protection

Setting the Motor Overload Pre-Alarm

If the motor overload protection function is enabled (i.e., L1-01 is set to other than 0) and you set H2-01 to

H2-03 (multi-function output terminals M1-M2, P1-PC, and P2-PC function selection) to 1F (motor overload

OL1 pre-alarm), the motor overload pre-alarm will be enabled. If the electronic thermal value reaches minimum 90% of the overload detection level, the output terminal that has been set will be turned ON.

Continuing Operation

This section explains functions for continuing or automatically restarting Inverter operation even if an error occurs.

Restarting Automatically After Power Is Restored

Even if a temporary power loss occurs, you can restart the Inverter automatically after power is restored to continue motor operation.

To restart the Inverter after power is restored, set L2-01 to 1 or 2.

If L2-01 is set to 1, when power is restored within the time set in L2-02, the Inverter will restart. If the time set in L2-02 is exceeded, alarm UV1 (main circuit undervoltage) will be detected.

If L2-01 is set to 2, when the main power supply is restored while the control power supply (i.e., power supply to the control panel) is backed up, the Inverter will restart. Consequently, alarm UV1 (main circuit undervoltage) will not be detected.

Setting Precautions

•

Error output signals are not output during momentary power loss recovery.

To continue Inverter operation after power has been restored, make settings so that Run Commands from the control main circuit terminal are stored even while power is suspended.

If the momentary power loss operation selection is set to 0 (Disabled), when the momentary power loss exceeds 15 ms during operation, alarm UV1 (main circuit undervoltage) will be detected.

Speed Search

The speed search function finds the actual speed of the motor that is rotating using inertia, and then starts smoothly from that speed. When restoring power after a temporary power loss, the speed search function switches connection from the commercial power supply, and then restarts the fan that is rotating using inertia.

Setting Precautions

•

When both external search commands 1 and 2 are set for the multi-function contact terminals, an OPE03

(invalid multi-function input selection) operation error may occur. Set either external search command 1 or external search command 2.

If speed search during startup is selected when using V/f control with PG, the Unit will start from the frequency detected by PG.

If performing speed search using external search commands, add an external sequence so that the period when the Run Command and external search command are both ON is at the very least the Minimum

Baseblock Time (L2-03).

If the Inverter output is equipped with a contact, set the contact operation delay time in the Speed Search

Wait Time (b3-05). The factory setting is 0.2 s. When not using the contact, you can reduce the search time by making the setting 0.0 s. After waiting for the speed search wait time, the Inverter starts the speed search.

Constant b3-02 is a current detection speed search (current detection level for search completion). When the current falls below the detection level, the speed search is viewed as completed, and the motor accelerates or decelerates to the set frequency. If the motor cannot restart, lower the set value.

If an overcurrent (OC) is detected when using speed search after recovery following a power loss, lengthen the Minimum Baseblock Time (L2-03).

Application Precautions for Speed Searches Using Estimated Speed

•

When using V/f control with or without a PG, always perform stationary autotuning for only line-to-line resistance before using speed searches based on estimated speeds.

When using vector control, always perform rotational or stationary autotuning (not stationary autotuning for line-to-line resistance only) before using speed searches based on estimated speeds.

If the cable length between the motor and Inverter is changed after autotuning has been performed, perform stationary autotuning for line-to-line resistance only again.

The motor will not operate when stationary autotuning or stationary autotuning for line-to-line resistance only is performed.

IMPORTANT

Continuing Operation

Speed Search Selection

Search Name

Search Method

Application Precautions

Estimated Speed

Estimates the motor speed when the search starts, and accelerates and decelerates from the estimated speed to the set frequency. You can also search including direction of motor rotation.

Current Detection

Starts speed search from the frequency when the temporary power loss was detected, or from the highest frequency, and performs speed detection at the current level during the search.

External Speed Search

Command

External search command 1 and external search command 2 become the same operation, estimating the motor speed and starting the search from the estimated speed.

External speed search command 1:

Starts speed search from the maximum output frequency.

External speed search command 2:

Starts speed search from the frequency reference set before the search command.

Cannot be used multi-motor drives, motors two or more frames smaller than the Inverter capacity, and high-speed motors (130 Hz min.)

In control method without PG, the motor may accelerate suddenly with light loads.

Restarting Operation After Transient Fault (Auto Restart Function)

If an Inverter fault occurs during operation, the Inverter will perform self-diagnosis. If no fault is detected, the

Inverter will automatically restart. This is called the auto restart function.

Set the number of auto restarts in constant L5-01. A fault reset is attempted every 5 ms after a fault occurs and minimum baseblock time has passed. The number of auto restarts is counted when the Inverter attempts a fault reset and restarts operation. The protection function will operate if a fault continues to occur after auto restarting the number of times set in L5-01.

The auto restart function can be applied to the following faults. If a fault not listed below occurs, the protection function will operate and the auto restart function will not.

• OC (Overcurrent) • RH (Braking resistor overheated)

• GF (Ground fault)

• PUF (Fuse blown)

• OV (Main circuit overvoltage)

• UV1 (Main Circuit Undervoltage, Main Circuit MC Operation Failure)

• PF (Main circuit voltage fault)

• OL2 (Inverter overload)

• OH1 (Motor overheat)

• OL3 (Overtorque)

• OL4 (Overtorque)

Input Terminal Functions

This section explains input terminal functions, which set operating methods by switching functions for the multi-function contact input terminals (S3 to S8).

Temporarily Switching Operation between Digital Operator and Control

Circuit Terminals

You can switch the Inverter Run Command inputs and frequency reference inputs between local (i.e., Digital

Operator) and remote (input method using b1-01 and b1-02).

You can switch between local and remote by turning ON and OFF the terminals if an output from H1-01 to

H1-06 (multi-function contact input terminal S3 to S8 function selection) has been set to 1 (local/remote selection).

To set the control circuit terminals to remote, set b1-01 and b1-02 to 1 (Control circuit terminals).

Stopping Acceleration and Deceleration (Acceleration/Deceleration

Ramp Hold)

The acceleration/deceleration ramp hold function stops acceleration and deceleration, stores the output frequency at that point in time, and then continues operation.

Set one of the constants H1-01 to H1-06 (multi-function contact input terminal S3 to S8 function selection) to

A (acceleration/deceleration ramp hold) to stop acceleration and deceleration when the terminal is turned ON and to store the output frequency at that point in time. Acceleration and deceleration will restart when the terminal is turned OFF.

If d4-01 is set to 1 and the Acceleration/Deceleration Ramp Hold command is input, the output frequency is still stored even after the power supply is turned OFF.

When d4-01 is set to 1, the output frequency on hold is stored even after the power supply is turned OFF. If performing operations using this frequency after the Inverter has also been turned OFF, input the Run

Command with the Acceleration/Deceleration Ramp Hold turned ON.

When d4-01 is set to 0 and a Run Command is input while the Acceleration/Deceleration Ramp Hold is turned ON, the output frequency will be set to zero.

If you input an Acceleration/Deceleration Ramp Hold command by error when decelerating during positioning, deceleration may be canceled.

Raising and Lowering Frequency References Using Contact Signals (UP/

DOWN)

The UP and DOWN commands raise and lower Inverter frequency references by turning ON and OFF a multifunction contact input terminal S3 to S8.

To use this function, set one of the constants H1-01 to H1-06 (multi-function contact input terminal S3 to S8 function selection) to 10 (UP command) and 11 (DOWN command). Be sure to allocate two terminals so that the UP and DOWN commands can be used as a pair.

The output frequency depends on the acceleration and deceleration time. Be sure to set b1-02 (Run Command selection) to 1 (Control circuit terminal).

Precautions

Setting Precautions

If multi-function input terminals S3 to S8 are set as follows, operation error OPE03 (Invalid multi-function input selection) will occur:

•

Only either the UP command or DOWN command has been set.

UP/DOWN commands and Acceleration/Deceleration Ramp Hold have been allocated at the same time.

-82

Application Precautions

• Frequency outputs using UP/DOWN commands are limited by the frequency reference upper and lower limits set in constants d2-01 to d2-03. Here, frequency references from analog frequency reference terminal A1 becomes the frequency reference lower limit. If using a combination of the frequency reference from terminal A1 and the frequency reference lower limit set in either constant d2-02 or d2-03, the larger lower limit will become the frequency reference lower limit.

•

If inputting the Run Command when using UP/DOWN commands, the output frequency accelerates to the frequency reference lower limit.

When using UP/DOWN commands, multi-step operations are disabled.

When d4-01 (Frequency Reference Hold Function Selection) is set to 1, the frequency reference held using the UP/DOWN functions is stored even after the power supply is turned OFF. When the power supply is turned ON and the Run Command is input, the motor accelerates to the frequency reference that has been stored. To reset (i.e., to 0 Hz) the stored frequency reference, turn ON the UP or DOWN command while the Run Command is ON.

Stopping the Inverter by Notifying Programming Device Errors to the

Inverter (External Fault Function)

The external fault function performs the error contact output, and stops the Inverter operation if the Inverter peripheral devices break down or an error occurs. The digital operator will display EFx (External fault [input terminal Sx]). The x in EFx shows the terminal number of the terminal that input the external fault signal. For example, if an external fault signal is input to terminal S3, EF3 will be displayed.

To use the external fault function, set one of the values 20 to 2F in one of the constants H1-01 to H1-06 (multifunction contact input terminal S3 to S8 function selection).

Select the value to be set in H1-01 to H1-06 from a combination of any of the following three conditions.

Selecting Analog Monitor Items

The digital operator monitor items (U1 [status monitor]) are output from multi-function analog output terminals FM-AC and AM-AC. Refer to Chapter 5 User Constants , and set the values for the part of U1-

(status monitor).

Alternatively, you can output monitor items (U1 [status monitor]) from analog output option terminal channels 1 and 2 on analog monitor boards AO-08 and AO-12. Refer to the table of constants, and set the values.

Adjusting the Analog Monitor Items

Adjust the output voltage for multi-function analog output terminals FM-AC and AM-AC using the gain and bias in H4-02, H4-03, H4-05, and H4-06. Also, adjust the output voltage for output channels 1 and 2 of Analog Output option boards AO-08 and AO-12 using the gain and bias in F4-02, F4-04, F4-05, and F4-06.

Adjusting the Meter

The output voltage for terminals FM-AC and AM-AC and output channels 1 and 2 of the AO option board can be adjusted while the Inverter is stopped. For example, just pressing the Enter Key and displaying the data setting display for H4-02 or H4-03 will cause the following voltage to be output by the FM-AC terminals.

10 V/100% monitor output × output gain (H4-02) + output bias (H4-03)

Just pressing the Enter Key and displaying the data setting display for F4-02 or F4-05 will cause the following voltage to be output to channel 1 of the AO option board.

10 V/100% monitor output × output gain (F4-02) + output bias (F4-05)

Output voltage

Gain x 10 V

Bias x 10/100 V

Individual Functions

Using MEMOBUS Communications

You can perform serial communications with MEMOCON-series Programmable Controllers (PLCs) or similar devices using the MEMOBUS protocol.

MEMOBUS Communications Configuration

MEMOBUS communications are configured using 1 master (PLC) and a maximum of 31 slaves. Serial communications between master and slave are normally started by the master, and the slave responds.

The master performs signal communications with one slave at a time. Consequently, you must set the address of each slave beforehand, so the master can perform signal communications using that address. Slaves receiving commands from the master perform the specified function, and send a response to the master.

IMPORTANT

1. Separate the communication cables from the main circuit cables and other wiring and power cables.

2. Use shielded cables for the communication cables, connect the shield cover to the Inverter earth terminal, and arrange the terminals so that the other end is not connected to prevent operating errors due to noise.

3. When using RS-485 communications, connect S+ to R+, and S- to R-, on the Inverter exterior.

R+ R S+ S

Procedure for Communicating with the PLC

Use the following procedure to perform communications with the PLC.

1. Turn OFF the power supply turned and connect the communication cable between the PLC and the

Inverter.

2. Turn ON the power supply.

3. Set the required communications constants (H5-01 to H5-07) using the Digital Operator.

4. Turn OFF the power supply, and check that the Digital Operator display has completely disappeared.

5. Turn ON the power supply once again.

6. Perform communications with the PLC.

INFO

Set the timer on the master to monitor response time from the slave. Set the master so that if the slave does not respond to the master within the set time, the same command message will be sent from the master again.

Data

Configure consecutive data by combining the storage register address (test code for a loopback address) and the data the register contains. The data length changes depending on the command details.

Individual Functions

Error Check

Errors are detected during communications using CRC-16. Perform calculations using the following method.

1. The factory setting for CRC-16 communications is usually 0, but when using the MEMOBUS system, set the factory setting to 1 (i.e., set all 16 bits to 1).

2. Calculate CRC-16 using MSB as slave address LSB, and LSB as the MSB of the final data.

3. Also calculate CRC-16 for response messages from the slaves, and compare them to the CRC-16 in the response messages.

MEMOBUS Message Example

An example of MEMOBUS command/response messages is given below.

Reading Storage Register Contents

Read the contents of the storage register only for specified quantities whose addresses are consecutive, starting from a specified address. The contents of the storage register are separated into higher place 8 bits and lower place 8 bits, and comprise the data within response messages in address order.

ENTER Command

When writing constants to the Inverter from the PLC using MEMOBUS communications, the constants are temporarily stored in the constant data area in the Inverter. To enable these constants in the constant data area, use the ENTER command.

There are two types of ENTER commands: ENTER commands that enable constant data in RAM, and

ENTER commands that write data to EEPROM (non-volatile memory) in the Inverter at the same time as enabling data in RAM.

The following table shows the ENTER command data. ENTER command data can only be written.

The ENTER command is enabled by writing 0 to register number 0900H or 0901H.

0900H

0910H

Contents

Write constant data to EEPROM

Constant data is not written to EEPROM, but refreshed in RAM only.

INFO

The maximum number of times you can write to EEPROM using the Inverter is 100 thousand. Do not frequently execute ENTER commands (0900H) written to EEPROM.

The ENTER command registers are write-only. Consequently, if reading these registers, the register address will become invalid (Error code: 02H).

Writing error during constants processing

Attempting to write constants from the PLC while processing constants in the Inverter.

Slave Not Responding

In the following cases, the slave will ignore the write function. If the slave address specified in the command message is 0, all slaves execute the write function, but do not return response messages to the master.

•

When a communications error (overrun, framing, parity, or CRC-16) is detected in the command message.

When the slave address in the command message and the slave address in the Inverter do not agree.

•

When the data that configures the message and the data time length exceeds 24 bits.

When the command message data length is invalid.

Application Precautions

Set a timer in the master to monitor response time from the slaves. Make the setting so that if no response is sent to the master from the slave within the set time, the same command message is sent again from the master.

Self-Diagnosis

The Inverter has a built-in function for self-diagnosing the operations of serial communications interface circuits. This function is called the self-diagnosis function. The self-diagnosis function connects the communications parts of the send and receive terminals, receives the data sent by the Inverter, and checks if communications are being performed normally.

Perform the self-diagnosis function using the following procedure.

1. Turn ON the power supply to the Inverter, and set 67 (communications test mode) in constant H1-05 (Terminal S7 Function Selection).

2. Turn OFF the power supply to the Inverter.

3. Perform wiring according to the following diagram while the power supply is turned OFF.

4. Turn ON the terminating resistance. (Turn ON pin 1 on DIP switch 1.)

5. Turn ON the power supply to the Inverter again.

Fig 6.60 Details of Communications Terminals

“Pass” will be displayed if self-diagnosis is completed without an error occurring.

If an error occurs, a CE (MEMOBUS communications error) alarm will be displayed on the Digital Operator, the error contact output will be turned ON, and the Inverter operation ready signal will be turned OFF.

Individual Functions

Using the Timer Function

Multi-function contact input terminals S3 to S8 can be designated as timer function input terminals, and multifunction output terminals M1-M2, P1-PC, and P2-PC can be designated as timer function output terminals. By setting the delay time, you can erase chattering from the sensors and switches.

•

Set one of the constants H1-01 to H1-06 (multi-function contact input terminal S3 to S8) to 18 (timer function input).

Set H2-01 to H2-03 (multi-function output terminals M1-M2, P1-PC, and P2-PC function selection) to 12

(timer function output).

Using PID Control

PID control is a method of making the feedback value (detection value) match the set target value. By combining proportional control (P), integral control (I), and derivative control (D), you can even control targets

(machinery) with play time.

The characteristics of the PID control operations are given below.

P control

I control

Outputs the amount of operation proportional to the deviation. You cannot, however, set the deviation to zero using P control alone.

Outputs the amount of operation that integrates the deviation. Used for matching feedback value to the target value. I control is not suited, however, to rapid variations.

D control Outputs the amount of operation derived from the deviation. Can respond promptly to rapid variations.

PID Control Operation

To understand the differences between each PID control operation (P, I, and D, the variation in the amount of operation (output frequency) is as shown in the following diagram when the deviation (i.e., the difference between the target value and feedback value) is fixed.

Setting Precautions

•

In PID control, the b5-04 constant is used to prevent the calculated integral control value from exceeding a specified amount. When the load varies rapidly, Inverter response is delayed, and the machine may be damaged or the motor may stall. In this case, reduce the set value to speed up Inverter response.

The b5-06 constant is used to prevent the arithmetic operation following the PID control calculation from exceeding a specified amount. Set taking the maximum output frequency to be 100%.

The b5-07 constant is used to adjust PID control offset. Set in increments of 0.1%, taking the maximum output frequency to be 100%.

Set the low pass filter time constant for the PID control output in b5-08. Enable this constant to prevent machinery resonance from occurring when machinery adhesive abrasion is great, or rigidity is poor. In this case, set the constant to be greater than the resonance frequency cycle. Increase this time constant to reduce Inverter responsiveness.

Using b5-09, you can invert the PID output polarity. Consequently, if you increase the PID target value, you can apply this constant to applications to lower the Inverter output frequency.

Using b5-10, you can apply gain to the PID control output. Enable this constant to adjust the amount of compensation if adding PID control output to the frequency reference as compensation.

When PID control output is negative, you can use constant b5-11 to invert the Inverter. When b1-04 (Prohibition of Reverse Operation) is set to 1 (enabled), however, PID output limit is 0.

With the Inverter, by setting an independent acceleration/deceleration time in constant b5-17, you can increase or decrease the PID target value using the acceleration/deceleration time. The acceleration/ deceleration function (constant C1) used normally, however, is allocated after PID control, so depending on the settings, resonance with PID control and hunting in the machinery may occur. If this happens, reduce constant C1 until hunting does not occur, and maintain the acceleration/deceleration time using b5-

17. Also, you can disable the set value in b5-17 from the external terminals during operation using multifunction input set value 34 (PID soft starter).

PID Control Block

The following diagram shows the PID control block in the Inverter.

PID Feedback Loss Detection

When performing PID control, be sure to use the PID feedback loss detection function. If PID feedback is lost, the Inverter output frequency may accelerate to the maximum output frequency.

When setting b5-12 to 1 and the status of the PID feedback value detection level in b5-13 is insufficient and continues for the time set in b5-14, an FbL (PID feedback reference lost) alarm will be displayed on the Digital Operator and Inverter operation will continue.

When b5-12 is set to 2, an FbL (PID feedback reference lost) error alarm will be displayed on the Digital

Operator, the error contact will operate, and Inverter operation will be stopped.

The time chart for PID feedback loss detection (set b5-12 to 2) is shown below.

PID Sleep

The PID sleep function stops the Inverter when the PID sleep function delay time continues while the PID control target value is at an insufficient level to operate the PID sleep function. When the PID sleep delay time continues and the PID control target value is above the PID sleep function operation level, Inverter operation will automatically resume.

When PID control is disabled, the PID sleep function is also disabled. When using the PID sleep function, select decelerate to stop or coast to stop as the stopping method.

Adjusting Energy-saving Control

The method of adjustment during energy-saving control operations differs depending on the control method.

Refer to the following when making adjustments.

V/f Control

In V/f control method, the voltage for optimum motor efficiency is calculated and becomes the output voltage reference.

•

• b8-04 (Energy-saving Coefficient) is set at the factory for motor use applied to the Inverter. If the motor capacity differs from the motor applied to the Inverter, set the motor capacity in E2-11 (Motor Rated Output). Also, adjust the output voltage in steps of 5 until it reaches minimum. The larger the energy-saving coefficient, the greater the output voltage.

To improve response when the load fluctuates, reduce the power detection filter time constant b8-05. If b8-

05 is set too small, however, motor rotations when the load is light may become unstable.

• Motor efficiency varies due to temperature fluctuations and differences in motor characteristics. Consequently, control motor efficiency online to optimize efficiency by causing minute variations in voltage using the search operation. Constant b8-06 (Search Operation Voltage Limiter) controls the range that control the voltage using the search operation. For 200 V Class Inverters, set the range to 100%/200 V, and for

400 V Class Inverters, set the range to 100%/400 V. Set to 0 to disable the search operation.

Vector Control

In vector control method, control the slip frequency so that motor efficiency is maximized.

• Taking the motor rated slip for the base frequency as optimum slip, calculate the optimum slip for motor efficiency for each frequency. In vector control, be sure to perform autotuning, and set the motor rated slip.

• If the motor performs hunting when using energy-saving control in vector control, reduce the set value in b8-02 (Energy-saving Gain), or increase the set value in b8-03 (Energy-saving Filter Time Constant).

In vector control method, the motor constants are set automatically using autotuning. If autotuning does not complete normally, set them manually.

Setting V/f Pattern

Set the V/f pattern in E1-03 when using V/f control (with or without a PG). There are two methods of setting the V/f pattern: Select one of the 15 pattern types (set value: 0 to E) that have been set beforehand, or set a user-defined V/f pattern (set value: F).

The factory setting for E1-03 is F. The contents of E1-03 when factory-set to F are the same as when E1-03 is set to 1.

The direction of the torque output from the motor will be determined by the sign of the analog signal input. It does not depend on the direction of the Run Command. The direction of torque will be as follows:

• Positive analog reference: Torque reference for forward motor rotation (counterclockwise as viewed from the motor output axis).

• Negative analog reference: Torque reference for reverse motor rotation (clockwise as viewed from the motor output axis).

Application Precautions

If the analog signal input level is 0 to 10 V or 4 to 20 mA, a forward torque reference will not be applied. To apply reverse torque, use an input level of -10 V to 10 V or switch the direction using a multi-function input set to 78 (polarity Reverse Command for external torque reference).

Speed Limiter and Priority Circuit (Speed Limit Function)

If the external torque reference and load are not balanced during torque control, the motor will accelerate in either the forward or reverse direction. The speed limit function is used to limit the speed to a specified value and it consists of the speed limiter circuit and priority circuit.

When the motor speed exceeds the speed limit value during torque control, the speed limiter circuit generates the suppression torque proportional to the speed above the limit value and adds to the torque reference. The priority circuit switches the internal torque reference to ASR output so that the motor speed does not exceed the speed limit value.

Application Precautions

There are two ways to set a speed limit: using an input from an analog input terminal and setting a speed limit in d5-04. The inputs methods for a speed limit are listed in the following table.

The value will be added to the value input on A1 to determine the speed limit.

Turn ON (I side) pin 2 of DIP switch S1 on the terminal board.

If H3-09 is set to 0, the sum of the input between TC2 and TC4 will be added the input between TC1 and TC4 to determine the speed limit.

IMPORTANT

The direction in which speed is controlled is determined by the sign of the speed limit signal and the direction of the Run Command.

• Positive voltage applied: The speed in the forward direction will be limited for forward operation.

• Negative voltage applied: The speed in the reverse direction will be limited for reverse operation.

If the direction of motor rotation and the command direction are not the same, speed will be limited to 0 as long as b5-05 is set to 0.

Torque Limit Operation Examples

Operation examples will be described separately for winding operation, in which the speed and motor torque are in the same directions, and rewinding operation, in which the speed and motor torque are in opposite directions.

Winding Operation

In a winding operation, the line (speed) and torque generated by the motor are in the same direction. For the winding operation, both the speed limit and the torque reference input are positive. The motor will accelerate when the torque reference input is larger than the load and will decelerate when it is smaller than the load. If the motor turns faster than the speed limit, a negative compensation value is output from the speed limiter circuit. When the speed then drops below the speed limit, a positive compensation value is output. The torque compensation is proportional to the ASR proportional gain. When the sum of the torque reference and the torque compensation output by the speed limiter is the same as the actual load, the motor will stop accelerating and run at a constant speed.

Rewinding Operation

In a rewinding operation, the line (speed) and torque generated by the motor are in the opposite directions. (In this example, we’ll assume that the line speed is positive and the torque reference input is negative.) For the rewinding operation, the speed limit is positive and the torque reference input is negative. If the motor turns faster than the speed limit, a negative compensation value is output from the speed limiter circuit. If the motor is rotating in reverse, a negative compensation value is output. If the speed is 0 or is below the speed limit, a 0

Individual Functions compensation value is output. In this way, the output from the speed limiter is used to maintain the motor speed between 0 and the speed limit. When the sum of the torque reference and the torque compensation output by the speed limiter is the same as the actual load, the motor will stop accelerating and run at a constant speed.

Consider the following information when adjusting the torque.

Torque Reference Delay Time: d5-02

The time constant of the primary filter in the torque reference section can be adjusted. This constant is used to eliminate noise in the torque reference signal and adjust the responsiveness to the host controller. Increase the setting if oscillation occurs during torque control.

Setting the Torque Compensation

Set multi-function analog input A2 or A3 to torque compensation (setting 14). When the amount of torque loss for mechanical loss or other factor at the load is input to one of these terminals, it is added to the torque reference to compensate for the loss. The direction of torque will be as follows:

• Positive voltage (current): Torque compensation reference for forward motor rotation (counterclockwise as viewed from the motor output axis).

• Negative voltage: Torque compensation reference for reverse motor rotation (clockwise as viewed from the motor output axis).

Since the polarity of the voltage input determines the direction, only forward torque compensation can be input when the 0 to 10 V or 4 to 20 mA signal level has been selected. If you want to input reverse torque compensation, be sure to select the 0 to ±10 V signal level.

Speed/Torque Control Switching Function

It is possible to switch between speed control and torque control when one of the multi-function inputs (H1-01 to H1-06) is set to 71 (Speed/Torque Control Change). Speed control is performed when the input is OFF and torque control is performed when the input is ON. Set d5-01 to switch speed/torque control.

Setting the Speed/Torque Control Switching Timer

The delay between a change in the speed/control switching function input (ON to OFF or OFF to ON) and the corresponding change in the control method can be set in d5-06. During the timer delay, the value of the 3 analog inputs will retain the values they had when the ON/OFF status of speed/torque control switching signal was changed. Use this delay to complete any changes required in external signals.

Application Precautions

• The frequency reference (during speed control) is set in b1-01. The speed limit during torque control is set in d5-03.

•

If the torque reference has been assigned to a multi-function analog input, terminal A2, or terminal A3, the input function changes when the control method is switched between torque control and speed control.

During speed control: The analog input terminal is used as the torque limit input.

During torque control: The analog input terminal is used as the torque reference input.

When the Run Command turns OFF, the control method when stopped will be for speed control. Even from the torque control method, the system will automatically change to speed control and decelerate to a stop when the Run Command turns OFF.

When A1-02 (control method selection) is set to 3 (flux vector control), the speed/torque change command

(a setting of 71) can be set for a multi-function input (H1-01 to H1-06) to switch between speed and torque control during operation. An example is shown below.

Adjusting ASR Proportional Gain 1 (C5-01)

This gain setting adjusts the responsiveness of the speed control (ASR). The responsiveness is increased when this setting is increased. Usually this setting is higher for larger loads. Oscillation will occur if this setting is increased too much.

The following diagram shows the type of changes that can occur in the response when the ASR proportional gain is changed.

Setting the Gain Switching Frequency (C5-07)

Set the switching frequency to about 80% of the motor operating frequency or the frequency at which oscillation occurs.

Low-speed Gain Adjustments (C5-03, C5-04)

Connect the actual load and adjust these constants at zero-speed. Increase C5-03 (ASR proportional gain 2) until there is no oscillation. Decrease C5-04 (ASR integral time 2) until there is no oscillation.

High-speed Gain Adjustments (C5-01, C5-02)

Adjust these constants at normal operating speed. Increase C5-01 (ASR proportional gain 1) until there is no oscillation. Decrease C5-02 (ASR integral time 1) until there is no oscillation. Refer to Fine Adjustments on page 6-137 for details on making fine adjustments of high-speed operation.

ASR Proportional Gain Switch Setting

When one of the multi-function inputs (H1-01 to H1-06) is set to 77, the input can be used to switch between

C5-01 (proportional gain 1) and C5-03 (proportional gain 2). Proportional gain 2 is used when the multi-function input is ON. This input has higher priority than the ASR switching frequency set in C5-07.

Gain Adjustments at Minimum Output Frequency

Operate the motor at the minimum output frequency. Increase C5-03 (ASR proportional gain 2) to a level where there is no oscillation. Decrease C5-04 (ASR integral time 2) to a level where there is no oscillation.

Monitor the Inverter's output current and verify that it is less than 50% of the Inverter rated current. If the output current exceeds 50% of the Inverter's rated current, decrease C5-03 and increase C5-04.

Gain Adjustments at Maximum Output Frequency

Operate the motor at the maximum output frequency. Increase C5-01 (ASR proportional gain 1) to a level where there is no oscillation. Decrease C5-02 (ASR integral time 1) to a level where there is no oscillation.

Fine Adjustments

When you want even finer gain adjustment, adjust the gain while observing the speed waveform. The adjustment method is the same as that for vector control.

Enable integral operation during acceleration and deceleration (by setting F1-07 to 1) when you want the motor speed to closely follow the frequency reference during acceleration and deceleration. Reduce the setting of C5-01 if overshooting occurs during acceleration, and reduce the setting of C5-03 and increase the setting of C5-04 if undershooting occurs when stopping. If overshooting and undershooting cannot be eliminated by adjusting only the gain, reduce the value of C5-05 speed control and reduce the limit of the frequency reference compensation value.

Individual Functions

Increasing the Speed Reference Response (Feed Forward Control)

(SPEC: E or Later Only)

Use feed forward control to increase the responsiveness to speed references. This function is effective for machines for which the ASR gain cannot be increased to a large value because doing so would result in vibrations. There is also the additional effect of making the system less prone to overshoot.

This function is valid only in flux vector control.

Setting Precautions

•

When N5-02 (Motor acceleration time) is not properly set, the acceleration time may not increase. The factory setting of N5-02 depends on the Inverter capacity. When the Inverter capacity is different from the motor capacity, calculate an appropriate acceleration time using the equation given in N5-02 of Chapter 5

User Constants or set the time that corresponds to the motor capacity referring to Factory Settings that

Change with the Control Method (A1-02) (Page 5-81)

When setting the feed forward proportional gain (N5-03), take the inertia of the motor to be equivalent to

1. If the speed reference response is slow, increase the feed forward proportional gain (N5-03). If overshoot occurs with the actual speed, or if a negative torque reference is output when acceleration is completed, reduce the feed forward proportional gain (N5-03).

When using the droop control function (i.e., if b7-01 is not set to 0.0), disable feed forward control (i.e., set

N5-01 to 0).

Droop Control Function (SPEC: E or Later Only)

Droop control is a function that allows the user to set the amount of motor slip.

When a single load is operated with two motors (such as in a crane conveyor), a high-resistance motor is normally used. This is to use torque characteristics that exhibit proportion movements due to changes in the secondary resistor to maintain torque balance with the load and overall speed balance with the load.

If droop control is used, a high-resistance motor characteristics can be set for a general-purpose motor.

The balance of the load is very different with different amounts of slip.

Zero-servo Function (SPEC: E or Later Only)

The zero-servo function holds the motor when the motor is stopped in what is call a zero-servo status. This function can be used to stop the motor even with an external force acts on the motor or the analog reference input is offset.

The zero-servo function is enabled when one of the multi-function inputs (H1-01 to H1-06) is set to 72 (zeroservo command). If the zero-servo command is ON when the frequency (speed) reference falls below the zerospeed level, a zero-servo status is implemented.

Application Precautions

•

Be sure to leave the Run Command input ON. If the Run Command is turned OFF, the output will be interrupted and the zero-servo function will become ineffective.

The holding force of the zero-servo is adjusted in b9-01. The holding force will increase if the value of the setting is increased, but oscillation and hunting will occur if the setting is too large. Adjust b9-01 after adjusting the speed control gain.

The zero-servo detection width is set as the allowable position offset from the zero-servo start position. Set

4 times the number of pulses from the PG.

The Zero-Servo End signal will go OFF when the zero-servo command is turned OFF.

IMPORTANT

Do not lock the servo for extended periods of time at 100% when using the zero-servo function. Inverter errors may result. Extended periods of servo lock can be achieved by ensuring that the current during the servolock is 50% or less or by increasing the Inverter capacity.

Changing Frequency Reference and Display Units

Set the Digital Operator frequency reference and display units using constant o1-03. You can change the units for the following constants using o1-03.

•

U1-01 (Frequency Reference)

U1-02 (Output Frequency)

•

U1-05 (Motor Speed)

U1-20 (Output Frequency after Soft Start) d1-01 to d1-17 (Frequency references)

Switching Monitors when the Power Supply Is ON

Using constant o1-02, select the monitor item (U1 [status monitor]) to be displayed on the Digital Operator when the power supply is turned ON. For monitors that can be displayed, refer to U1 in Chapter 5

User Constants .

Digital Operator Functions

Setting Precautions

If selecting monitor constants other than U1-01 (Frequency Reference), U1-02 (Output Frequency), and U1-

03 (Output Current), first select the monitor items to be displayed in o1-01, and then set o1-02 to 4.

Disabling the STOP Key

If b1-02 (Operation Method Selection) is set to 1, 2, or 3, the Stop Command from the STOP Key on the Digital Operator is an emergency Stop Command.

Set o2-02 to 0 to disable emergency Stop Commands from the STOP Key on the Digital Operator.

Disabling the LOCAL/REMOTE Key

Set o2-01 to 0 to disable the LOCAL/REMOTE Key on the Digital Operator. You cannot switch Inverter reference inputs set using reference inputs from the Digital Operator, b1-01 (Reference Selection), or b1-02

(Operation Method Selection).

Initializing Changed Constant Values

You can save to the Inverter constant set values that you have changed as constant initial values. Change the set values from the Inverter factory settings, and then set o2-03 to 1.

Set A1-03 (Initialize) to 1110 to initialize the Inverter constants using the user-set initial values in memory. To clear the user-set initial values in memory, set o2-03 to 2.

Setting the Frequency Reference using the UP and DOWN Keys without Using the

Enter Key

Use this function when inputting frequency references from the Digital Operator. When o2-05 is set to 1, you can increment and decrement the frequency reference using the UP and DOWN Keys without using the Enter

Key.

For example, enter the Run Command using a 0 Hz reference, and then continuously press the UP Key to increment the frequency reference by 0.01 Hz only for the first 0.5 s, and then by 0.01 Hz every 80 ms for 3 s thereafter. Press and hold down the UP Key for 3 s minimum to reach the maximum output frequency 10 s after that. The frequency reference that has been set will be stored in memory 5 s after the UP or DOWN Keys are released.

Clearing Cumulative Operation Time

Set the cumulative operation time initial value in time units in constant o2-07. Set o2-07 to 0 to clear U1-13

(Inverter Operating Time).

Clearing Inverter Cooling Fan Operation Time

Set the fan operation time initial value in time units in constant o2-10. Set o2-10 to 0 to clear U1-40 (Cooling

Fan Operating Time).

Using PG Speed Control Board

There are four types of PG Speed Control Board that can be used in V/f control with PG.

• PG-A2: A-phase (single) pulse input, compatible with open collector or complimentary outputs.

•

PG-B2: A/B-phase pulse input, compatible with complimentary outputs.

PG-D2: A-phase (single) pulse input, compatible with line drivers.

PG-X2: A/B/Z-phase pulse input, compatible with line drivers.

There are two types of PG Speed Control Boards that can be used for flux vector control.

• PG-B2: A/B phase pulse inputs, complementary outputs

• PG-X2: A/B/Z phase pulse inputs, line driver outputs

For the connection diagram, refer to page 2-36 to 2-38.

Setting Number of PG Pulses

Set the number of PG (Pulse Generator/Encoder) pulses in pulses/rotation. Set the number of A-phase or Bphase pulses per 1 motor rotation in F1-01.

Matching PG Rotation Direction and Motor Rotation Direction

Constant F1-05 matches the PG rotation direction and the motor rotation direction. If the motor is rotating forwards, set whether it is A-phase driven or B-phase driven. Make this setting when using PG-B2 or PG-X2.

Yaskawa standard PG used is A-phase driven (CCW) when motor rotation is forward.

Fig 6.78 PG Rotation Direction Setting

Generally, PG is A-phase driven when rotation is clockwise (CW) see from the input axis. Also, motor rotation is counter-clockwise (CCW) seen from the output side when Forward Commands are output. Consequently, when motor rotation is forward, PG is normally A-phase driven when a load is applied, and B-phase driven when a load is not applied.

Options

Setting Number of Gear Teeth Between PG and Motor

Set the number of PG gear teeth in F1-12 and F1-13. If there are gears between the motor and PG, you can operate the motor by setting the number of gear teeth.

When the number of gear teeth has been set, the number of motor rotations within the Inverter is calculated using the following formula.

No. of motor rotations (min

− 1

.) = No. of input pulses from PC × 60 / F1-01 × F1-13 (No. of gear teeth on load side) / F1-12 (No. of gear teeth on motor side)

Matching Motor Speed During Acceleration and Deceleration to Frequency Reference

You can select whether to enable or disable integral operation during acceleration and deceleration when using

V/f with PG control.

To match the motor speed as closely as possible to the frequency reference even during acceleration and deceleration, set F1-07 to 1.

If F1-01 is set to 1, overshoot or undershoot may occur easily immediately after acceleration and deceleration. To minimize the possibility of overshoot or undershoot occurring, set F1-01 to 0.

IMPORTANT

Setting PG Pulse Monitor Output Dividing Ratio

This function is enabled only when using PG speed control board PG-B2. Set the dividing ratio for the PG pulse monitor output. The set value is expressed as n for the higher place digit, and m for the lower place 2 digits. The dividing ratio is calculated as follows:

Dividing ratio = (1 + n)/m (Setting range) n: 0 or 1, m: 1 to 32

F1-06 = n

The dividing ratio can be set within the following range: 1/32 ≤ F1-06 ≤ 1. For example, if the dividing ratio is

1/2 (set value 2), half of the number of pulses from the PG are monitor outputs.

Detecting PG Open Circuit

Select the stopping method when PG cable disconnected is detected and the PG open circuit (PGO) detection time.

When the Inverter is operating with the frequency reference set to 1% minimum (except when operating on direct current), if the speed feedback from PG is greater than the time setting in F1-14, PGO is detected.

Detecting Motor Overspeed

An error is detected when the number of motor rotations exceeds the regulated limit. An overspeed (OS) is detected when a frequency that exceeds the set value in F1-08 continues for longer than the time set in F1-09.

After detecting an overspeed (OS), the Inverter stops according to the setting in F1-03.

Detecting Speed Difference between the Motor and Speed Reference

An error is detected when the speed deviation (i.e., the difference between the designated speed and the actual motor speed) is too great. Speed deviation (DEV) is detected after a speed agreement is detected and when the speed reference and actual workpiece speed are within the setting of L4-02, if a speed deviation great than the set value in F1-10 continues for longer than the time set in F1-11. After a speed deviation is detected, the

Inverter stops according to the setting in F1-04.

Using an Analog Reference Board (SPEC: E or Later Only)

AI-14B provides 3 channels of bi-polar inputs with 13-bit A/D conversion accuracy (and a + sign bit). The function of each channel is determined by the setting of F2-01.

AI-14U provides 2 channels of bi-polar inputs with 14-bit A/D conversion accuracy. Channel 1 is a voltage input and channel 2 is a current input. The sum of channels 1 and 2 is a frequency input. F2-01 does not need to be set for the AI-14U.

Application Precautions

•

The maximum frequency (100% speed) reference will be used when the binary input is set (setting: 6 or 7) and all bits are 1.

Setting F3-01 to 6 is valid only when the D1-16H2 is used. Using this setting, a frequency from 0.00 to

399.8 Hz can be set in BCD. The sign bit is used as a data bit, so only positive (plus) data can be set. Also, the digit starts from 0, so the minimum setting is 0.02 Hz.

Using Inverters for Elevating Machines

This section describes precautions to be observed when using the Varispeed F7 for elevating machines such as elevators and cranes.

Brake ON/OFF Sequence

For the holding brake’s ON/OFF sequence, use the following Inverter output signals according to the set control method.

* 1. This example shows multi-function output terminals M1-M2 used for the holding brake ON/OFF signal.

Do not set H2-01 to 0 (During run).

* 2. This is the standard setting range for open-loop vector control. For V/f control, set to approximately the motor rated slip frequency +0.5 Hz.

If the set value is too low, the motor torque is insufficient and the load may slip when the brake is applied. Be sure to set L4-01 to a value larger than that of E1-09 (Min. output frequency) and larger than that of L4-02 shown in Figure 6.80. If the set value is too large, the motor may not run smoothly when it starts running.

* 3. The hysteresis in frequency detection 2 can be adjusted (from 0.1 to 0.5 Hz) by L4-02 (speed agree detection width). Change the setting to approximately 0.1 Hz if there are drops while stopping.

Stall Prevention during Deceleration

If connecting a braking resistor to discharge regenerative energy, be sure to set Stall prevention selection during decel (L3-04) to 0 (Disabled).

IMPORTANT

If Stall prevention selection during decel (L3-04) is set to 1, 2, or 3 , the motor may not stop within the specified decelerating time.

Stall prevention selection during accel (L3-01) and Stall prevention selection during running (L3-05) should be set to their initial values 1 (Enabled) to enable these functions.

Autotuning

Always perform autotuning with the motor before operating using vector control. Be sure to disconnect the motor from the load before conducting autotuning. Conducting autotuning while the motor is connected to an elevating machine system is dangerous because it automatically runs the motor for approximately one minute.

IMPORTANT

1. When the motor cannot be disconnected from the load, perform stationary autotuning 1 (T1-01 = 1) or stationary autotuning 2 (T1-01 = 4) . Stationary autotuning will apply current to the motor in its stopped condition and automatically measure the motor data. In the initial running period after stationary autotuning

1 (T1-01 = 1) (20% speed min., fixed speed for 1 s min.), the motor data measured by autotuning will automatically be corrected.

2. To improve low-speed torque characteristics using V/f control, conduct stationary autotuning for line to line resistance only (T1-01 = 2).

3. When conducting autotuning on wound motor or other special types of motors, obtain a test report for the motor in advance and confirm that the E2 motor constants after autotuning do not vary greatly from those of the test report.

Braking Resistor Overheating Protection

When using a braking resistor other than the Braking Resistor Unit, provide a sequence with a thermal overload relay or similar means to turn off the power input to the Inverter when it detects resistor overheating. See the Connection Diagram on page 2-3 for this sequence circuit.

Momentary Power Loss Restart

Do not use the momentary power loss restart and fault restart functions in applications for elevating machines.

Make sure that L2-01=0 and L5-01=0. If these functions are used, the motor coasts to a stop with the brake contact open when a momentary power loss or fault occurs during operation, possibly resulting in serious accidents.

Torque Limit

The torque limit values (L7-01 to L7-04) are the motor's rated torque. When there is a possibility of insufficient torque at start-up or other time, increase the Inverter capacity and set the torque limit value to between

200% and 300% (factory setting is 200%).

Using Inverters for Elevating Machines

I/O Open-phase Protection and Overtorque Detection

To prevent the machine from falling when the motor is open-phase or a similar situation, enable L8-05 and L8-

07 (Input and output open-phase protection selection) and L6-01 to L6-06 (Overtorque detection) (factory setting is Disabled).

Falling detection or a similar safety measure should also be provided on the machine side.

External Baseblock Signal

If the external baseblock command (settings 8 and 9 of H1-01 to H1-06) is input while the motor is running, the motor will immediately coast to a stop. Do not input the external baseblock command while the motor is running unless necessary.

Make sure that the holding brake operates when using the external base block command for an emergency stop or interlock to start the Inverter.

If the external baseblock command is input and immediately reset, the Inverter does not output voltage during the value of L2-03 (Min. baseblock time), which factory setting is 0.5 to 2.0 seconds depending on the Inverter capacity. Do not use the external baseblock command in an application where the motor is frequently started and stopped.

Acceleration/Deceleration Time

If the delay time for the holding brake’s mechanical operation is not taken into consideration and the acceleration/deceleration time on the Inverter side is set to a time that is too short, and overcurrent or wear on the brakes may occur at staring or the load will slip at stopping because the holding brake does not operate on time. If so, use the dwell function at start described on page 6-174 or the dwell function at stop described on page 6-175 to tune the timing for the holding brake.

Magnetic Contactor on the Inverter’s Output-side

Do not install a magnetic contactor between the Inverter and the motor. If a magnetic contactor must be installed because of local electrical codes or regulations or to operate motors with an Inverter, excluding emergencies, open or close the magnetic contactor only when the holding brake is fully closed and the Inverter is in baseblock status with the baseblock signal ON.

If the magnetic contactor is opened or closed while the Inverter is controlling the motor or DC injection braking (Zero-speed control), surge voltage or a current from the motor by full-voltage starting may cause an

Inverter fault.

When a magnetic contactor is installed between the Inverter and the motor, set L8-07 (Output open-phase protection selection) to 1 or 2 (Enabled).

Note 1. Do not change C4-01 (Torque compensation gain) from its factory setting of 1.00 when using open-loop vector control.

2. If speeds are inaccurate during regeneration in open-loop vector control, enable Slip compensation selection during regeneration (C3-04 = 1). If speeds are inaccurate in the high-speed range, enable Output voltage limit operation selection (C3-05 = 1).

3. Do not use Slip compensation gain (C3-01) during V/f control (A1-02 = 0). (It is not used with the factory setting.)

-174

4. Use the ASR constants (C5-01 to C5-05) in their factory settings when using V/f control with PG (A1-02 = 1). Vibration may occur if these constants are changed greatly from their factory settings.

5. The torque and speed response of high-resistance (high-slip) motors are insufficient. Use appropriate adjustments to improve them. On the contrary, low-resistance (low-slip) motors are easily subject to hunting and vibration. Here too, use appropriate adjustments to improve them.

6. The current during startup may increase when C4-02 (Torque compensation primary delay time constant) is increased. Check the current during startup while adjusting this constant.

Reducing Shock during Elevating Machine Start, Stop, Acceleration, and

Deceleration

When the riding comfort during start, stop, acceleration, and deceleration is of high importance, as it is for elevators in which people ride, adjust the following constants.

S-curve Characteristics, Acceleration/Deceleration Times

Output frequency

C2-01

C2-02

(High speed)

C2-03

(Low speed)

C2-04

C2-03

C2-04

Acceleration time Deceleration time DC injection braking when stopping

(Zero-speed control for flux vector control)

IMPORTANT

1. The factory setting for C2-04 (S-curve characteristic time at deceleration end) is 0.00 second, while the factory setting for all other S-curve characteristic times is 0.20 second. Make appropriate settings for the accel/decel times and S-curve characteristic times at each point. (S-curve characteristic time = Approximately 0.2 to 1.0 second)

2. The accel/decel rate can be automatically switched during acceleration and deceleration by using C1-11

(Accel/decel time switching frequency). (Factory setting: Disabled)

Output frequency ≥ set frequency: C1-01, C1-02 accel/decel times

Output frequency < set frequency: C1-07, C1-08 accel/decel times

3. If the output frequency during the S-curve characteristic time for deceleration falls below the value set for

E1-09 (Min. output frequency), the S-curve characteristic will be cancelled, and the DC injection braking

(Zero-speed control) will be applied.

4. Do not use the S-curve characteristic for applications where a short run time is desired, such as in cranes and hoists. (S-curve characteristic time = Approximately 0.0 to 0.2 second)

Using Inverters for Elevating Machines

If the mechanical operation of the holding brake is slow, use the dwell function at start to prevent brake wear, and accelerate after the brake is completely open.

IMPORTANT

1. When using open-loop vector control and V/f control, set b6-01 (Dwell frequency at start) higher than frequency detection 2 (frequency when brakes open).

2. If the motor tends to have insufficient torque when started, use the DC injection braking function to allow sufficient motor current (torque) before starting.

When the holding brake’s mechanical operation is slow, use DC injection braking (zero-speed control for flux vector control) until the brakes are fully closed to prevent the brakes from slipping when stopping.

IMPORTANT

1. When the load cannot be maintained sufficiently using DC injection braking with open-loop vector control and V/f control, use the dwell functions at stop.

• b6-03 (Dwell frequency at stop): Min. output frequency to 3.0 Hz.

The value must be less than the frequency when frequency detection 2 is OFF (L4-01 − L4-02).

• b6-04 (Dwell time at stop): 0.3 to 0.5 s

[b2-04 (DC injection braking at stop): 0.0 s]

2. If the Inverter and motor must be isolated while stopping using a magnetic contactor, for example in an elevator, fully close the holding brakes and isolate the Inverter during baseblock (during baseblock signal: ON) as stipulated by law in the EU.

During motor control or DC injection braking (zero-speed control), an Inverter error may occur due to surge voltage. When a magnetic contactor is used between the Inverter and motor, set L8-07 (Output openphase protection) to 1 (enabled).

Torque Compensation (Flux Vector Control Only) (SPEC: E or Later Only)

When flux vector control is used, the torque compensation signals corresponding to the load can be input from the multi-function analog input terminals in advance to reduce shock, such as that caused by opening and closing holding brakes. The load size and motoring/regenerating status must be detected at the machine side in advance. Check that polarity is correct. Incorrect polarity will increase the shock.

IMPORTANT

1. For either increasing or decreasing torque, externally maintain the torque compensation signals during operation to prevent them from fluctuating. Fluctuation in compensation signals during operation may result in vibration.

2. If reverse run is used for lifting and forward run is used for lowering, the torque compensation signal polarity must be reversed.

Analog Input Filter Time Constant

If noise enters the analog frequency reference during operation using analog frequency reference (b1-01 = 1), and operation becomes rough, implement noise countermeasures and also set H3-12 (Analog input filter time constant) to between 0.01 and 0.10 s.

Confirming Startup Current and Reducing Carrier Frequency

When performing trial operation, check the motor current using the Digital Operator or a clamp ammeter with and without a mechanical load. An extremely high current will flow if the motor torque at start is insufficient, or if timing is not correct and the motor locks with the holding brake.

If the current at start is more than the Inverter overload level, the IGBT in the Inverter will be subject to heat stress, resulting in a shortened life span. Refer to the previous precautions and take measures, such as retuning and reducing the load until the current drops to less than the Inverter overload level. If particularly low noise is not required, do not increase the Inverter’s carrier frequency to reduce the influence of heat stress.

Overvoltage Inhibit Function (SPEC: E or Later Only)

Leave L3-11 (Overvoltage inhibit function selection) set to 0 (disabled: factory setting). This function is used to prevent overvoltage tripping when the braking resistor is not used with a regenerative load. When this function is enabled, the torque reference on the regenerative side is automatically inhibited in the Inverter during regeneration. Using this function in elevating machines is dangerous because the elevator may slip and fall.

Contact your Yaskawa representative for details on applications such as high-speed elevators (speed: 2 m/s or higher), direct-drive elevators, or Inverters designed for cranes.

Protective and Diagnostic Functions

This section describes the alarm functions of the Inverter. The alarm functions include fault detection, alarm detection, operation error detection, and autotuning error detection.

Fault Detection

When the Inverter detects a fault, the fault contact output operates, and the Inverter output is shut OFF causing the motor to coast to a stop. (The stopping method can be selected for some faults, and the selected stopping method will be used with these faults.) A fault code is displayed on the Digital Operator.

When a fault has occurred, refer to the following table to identify and correct the cause of the fault.

Be sure to turn Run Command to OFF first, use one of the following methods to reset the fault before restarting the Inverter.

•

Set a multi-function contact input (H1-01 to H1-06) to 14 (Fault Reset) and turn ON the fault reset signal.

Press the RESET Key on the Digital Operator.

Turn the main circuit power supply OFF and then ON again.

Meaning

Overcurrent

The Inverter output current exceeded the overcurrent detection level. (200% of rated current)

Probable Causes

• A short-circuit or ground fault occurred at the Inverter output. (A short or ground fault can be caused by motor burn damage, worn insulation, or a damaged cable.)

• The load is too large or the acceleration/deceleration time is too short.

• A special-purpose motor or motor with a capacity too large for the

Inverter is being used.

• A magnetic switch was switched at the Inverter output.

Corrective Actions

Reset the fault after correcting its cause.

Ground Fault

The ground fault current at the

Inverter output exceeded approximately 50% of the Inverter rated output current.

A ground fault occurred at the Inverter output. (A ground fault can be caused by motor burn damage, worn insulation, or a damaged cable.)

Reset the fault after correcting its cause.

Fuse Blown

The fuse in the main circuit is blown.

The output transistor has failed because of a short-circuit or ground fault at the Inverter output.

Check whether there is a short-circuit between the following terminals. A short-circuit will damage the output transistor:

B1 ( 3) ←→ U, V, W

←→ U, V, W

Replace the Inverter after correcting the cause.

Main Circuit Overvoltage

The main circuit DC voltage exceeded the overvoltage detection level.

200 V Class: Approx. 410 V

400 V Class: Approx. 820 V

The deceleration time is too short and the regenerative energy from the motor is too large.

The regenerative energy when an overshoot occurs after acceleration is completed is too large.

Increase the deceleration time or connect a braking resistor (or

Braking Resistor Unit).

In vector control, enable (Set to 1) the overvoltage inhibit selection

(L3-11).

The power supply voltage is too high.

Decrease the voltage so it's within specifications.

* The ground fault here is one which occurs in the motor wiring. A ground fault with low resistance which occurs in motor cables or terminals may not be detected.

Troubleshooting

Due to constant setting errors, faulty wiring, and so on, the Inverter and motor may not operate as expected when the system is started up. If that should occur, use this section as a reference and apply the appropriate measures.

If the contents of the fault are displayed, refer to Protective and Diagnostic Functions .

If Constant Constants Cannot Be Set

Use the following information if an Inverter constant cannot be set.

The display does not change when the Increment and Decrement Keys are pressed.

The following causes are possible.

The Inverter is operating (drive mode).

There are some constants that cannot be set during operation. Turn the Inverter off and then make the settings.

Constant write enable is input.

This occurs when "constant write enable" (set value: 1B) is set for a multi-function input terminal (H1-01 to

H1-06). If the constant write enable input is OFF, the constants cannot be changed. Turn it ON and then set the constants.

Passwords do not match. (Only when a password is set.)

If the constant A1-04 (Password) and A1-05 (Password Setting) numbers are different, the constants for the initialize mode cannot be changed. Reset the password.

If you cannot remember the password, display A1-05 (Password Setting) by pressing the Reset/Select Key and the Menu Key simultaneously while in the A1-04 display. Then reset the password. (Input the reset password in constant A1-04.)

Troubleshooting

If the Motor Does Not Operate

Use the following information if the motor does not operate.

The motor does not operate when the RUN Key on the Digital Operator is pressed.

The following causes are possible.

IMPORTANT

If the Inverter is not in drive mode, it will remain in ready status and will not start. Press the Menu Key to make the DRIVE indicator flash, and enter the drive mode by pressing the DATA/ENTER Key. The DRIVE indicator will light when drive mode is entered.

The operation method setting is wrong.

If constant b1-02 (Operation Method Selection) is set to 1 (control circuit terminal), the motor will not operate when the Run Key is pressed. Either press the LOCAL/REMOTE Key* to switch to Digital Operator operation or set b1-02 to 0 (Digital Operator).

The LOCAL/REMOTE Key is enabled by setting o2-01 to 1 and disabled by setting o2-01 to 2. It is enabled when the drive mode is entered.

INFO

The frequency reference is too low.

If the frequency reference is set below the frequency set in E1-09 (Minimum Output Frequency), the Inverter will not operate.

Raise the frequency reference to at least the minimum output frequency.

There is a multi-function analog input setting error.

If H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function Analog

Input Terminal A3 Function Selection) is set to 1 (frequency gain), and if no voltage (current) is input, then the frequency reference will be zero. Check to be sure that the set value and analog input value are correct.

The motor does not operate when an external operation signal is input.

The following causes are possible.

The Inverter is not in drive mode.

If the Inverter is not in drive mode, it will remain in ready status and will not start. Press the MENU Key make the DRIVE indicator flash, and enter the drive mode by pressing the DATA/ENTER Key. The DRIVE indicator will light when drive mode is entered.

-20

The operation method selection is wrong.

If constant b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an external operation signal is input. Set b1-02 to 1 (control circuit terminal) and try again.

Similarly, the motor will also not operate if the LOCAL/REMOTE Key has been pressed to switch to Digital

Operator operation. In that case press the LOCAL/REMOTE Key* again to return to the original setting.

The LOCAL/REMOTE Key is enabled by setting o2-01 to 1 and disabled by setting o2-01 to 2. It is enabled when the drive mode is entered.

INFO

A 3-wire sequence is in effect.

The input method for a 3-wire sequence is different than when operating by forward/stop and reverse/stop (2wire sequence). When 3-wire sequence is set, the motor will not operate even when an input terminal suitable for forward run/stop and reverse run/stop is turned ON.

When using a 3-wire sequence, refer to the timing chart, set the multi-function input terminal (H1-01 through

H1-06, terminals S3 to S8) to 0, and input the proper signals.

When using a 2-wire sequence, set the multi-function input terminal (H1-01 through H1-06, terminals S3 to

S8) to a value other than 0.

The frequency reference is too low.

If the frequency reference is set below the frequency set in E1-09 (Minimum Output Frequency), the Inverter will not operate. Raise the frequency reference to at least the minimum output frequency.

There is a multi-function analog input setting error.

If multi-function analog inputs H3-05 or H3-09 is set to 1 (frequency gain), and if no voltage (current) is input, then the frequency reference will be zero. Check to be sure that the set value and analog input value are correct.

The motor stops during acceleration or when a load is connected.

The load may be too heavy. The Inverter has a stall prevention function and an automatic torque boost function, but the motor responsiveness limit may be exceeded if acceleration is too rapid or if the load is too heavy.

Lengthen the acceleration time or reduce the load. Also consider increasing the motor capacity.

The motor does not accelerate.

If the torque limit settings (L7-01 to L7-04) or the torque reference input (torque control) are too small, the motor may not be able to accelerate. Check the settings and input values.

The motor only rotates in one direction.

"Reverse run prohibited" is selected. If b1-04 (Prohibition of Reverse Operation) is set to 1 (reverse run prohibited), the Inverter will not receive Reverse Run Commands. To use both forward and reverse operation, set b1-04 to 0.

Troubleshooting

If the Direction of the Motor Rotation is Reversed

If the motor operates in the wrong direction, the motor output wiring is faulty. When the Inverter T1(U),

T2(V), and T3(W) are properly connected to the motor T1(U), T2(V), and T3(W), the motor operates in a forward direction when a Forward Run Command is executed. The forward direction depends on the manufacturer and the motor type, so be sure to check the specifications.

The direction of rotation can be reversed by switching two wires among T1(U), T2(V), and T3(W).

If the Motor Does Not Put Out Torque or If Acceleration is Slow

Use the following information if the motor does not output torque or if acceleration is too slow.

The torque limit has been reached.

When a torque limit has been set in constants L7-01 to L7-04, no torque will be output beyond that limit. This can cause the torque to be insufficient, or the acceleration time to be too long. Check to be sure that the value set for the torque limit is suitable.

If torque limits have been set for the multi-function analog input (H3-09 or H3-05 = 10 to 12 or 15), check to be sure that the analog input value is suitable.

The stall prevention level during acceleration is too low.

If the value set for L3-02 (Stall Prevention Level during Acceleration) is too low, the acceleration time will be too long. Check to be sure that the set value is suitable.

The stall prevention level during running is too low.

If the value set for L3-06 (Stall Prevention Level during Running) is too low, the speed will drop before outputting torque. Check to be sure that the set value is suitable.

Autotuning has not been performed for vector control

Vector control will not be perform if autotuning has not been performed. Perform autotuning separately for the motor, or set the motor constants through calculations. Alternatively, change the Control Method Selection

(A1-02) to V/f control (0 or 1).

If the Motor Operates Higher Than the Reference

Use the following information if the motor operates higher than the reference.

The analog frequency reference bias setting is wrong (the gain setting is wrong).

The frequency reference bias set in constant H3-03 is added to the frequency reference. Check to be sure that the set value is suitable.

-22

A signal is being input to the frequency reference terminal A2 or A3 .

When 0 (frequency reference) is set for constant H3-09 (Multi-function Analog Input Terminal A2 Function

Selection) or H3-05 (Multi-function Analog Input Terminal A3 Function Selection) , a frequency corresponding to the terminal A2 or A3 input voltage (current) is added to the frequency reference. Check to be sure that the set value and analog input value are suitable.

If the Slip Compensation Function Has Low Speed Precision

If speed control accuracy is low for the slip compensation function, the slip compensation limit has been reached. With the slip compensation function, compensation cannot be carried out beyond the slip compensation limit set in constant C3-03. Check to be sure that the set value is suitable.

If There is Low Speed Control Accuracy at High-speed Rotation in Openloop Vector Control Method

The motor's rated voltage is high.

The Inverter's maximum output voltage is determined by its input voltage. (For example, if 200 VAC is input, then the maximum output voltage will be 200 VAC.) If, as a result of vector control, the output voltage reference value exceeds the Inverter output voltage maximum value, the speed control accuracy will decrease. Use a motor with a low rated voltage (i.e., a special motor for use with vector control), or change to flux vector control.

If Motor Deceleration is Slow

Use the following information when the motor deceleration is slow.

The deceleration time is long even when braking resistor is connected.

The following causes are possible.

"Stall prevention during deceleration enabled" is set.

When braking resistor is connected, set constant L3-04 (Stall Prevention Selection during Deceleration) to 0

(disabled) or 3 (with braking resistor). When this constant is set to 1 (enabled, the factory setting), braking resistor does not fully function.

The deceleration time setting is too long.

Check the deceleration time setting (constants C1-02, C1-04, C1-06, and C1-08).

Motor torque is insufficient.

If the constants are correct and there is no overvoltage fault, then the motor's power is limited. Consider increasing the motor capacity.

Troubleshooting

The torque limit has been reached.

When a torque limit has been set in constants L7-01 to L7-04, no torque will be output beyond that limit. This can cause the deceleration time to be too long. Check to be sure that the value set for the torque limit is suitable.

If H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function Analog

Input Terminal A3 Function Selection) is set to 10, 11, 12 or 15 (positive and negative torque limit), check to be sure that the analog input value is suitable.

If the Vertical-axis Load Drops When Brake is Applied

The sequence is incorrect. The Inverter goes into DC injection braking status for 0.5 seconds after deceleration is completed. (This is the factory-set default.)

To ensure that the brake holds, set frequency detection 2 (H2-01 = 5) for the multi-function contact output terminals (M1 and Mw) so that the contacts will turn OFF when the output frequency is greater than L4-01 (3.0

to 5.0 Hz). (The contacts will turn ON below L4-01.)

There is hysteresis in frequency detection 2 (i.e., a frequency detection width, L4-02 = 2.0 Hz). Change the setting to approximately 0.5 Hz if there are drops during stop. Do not use the multi-function contact output run signal (H2-01 = 0) for the brake ON/OFF signal.

If the Motor Overheats

Take the following steps if the motor overheats.

The load is too big.

If the motor load is too heavy and the motor is used with the effective torque exceeding the motor's rated torque, the motor will overheat. Some motor rating are given for short period performance and are not continuous ratings. Reduce the load amount by either lightening the load or lengthening the acceleration/deceleration time. Also consider increasing the motor capacity.

The ambient temperature is too high.

The motor rating is determined within a particular ambient operating temperature range. The motor will burn out if it is run continuously at the rated torque in an environment in which the maximum ambient operating temperature is exceeded. Lower the motor's ambient temperature to within the acceptable ambient operating temperature range.

The withstand voltage between the motor phases is insufficient.

When the motor is connected to the Inverter output, a surge is generated between the Inverter switching and the motor coil. Normally the maximum surge voltage is three times the Inverter's input power supply voltage

(i.e., 1,200 V for 400 V Class). Be sure to use a motor with a withstand voltage between the motor phases that is greater than the maximum surge voltage. In particular, when using a 400 V Class Inverter, use a special motor for Inverters.

-24

Autotuning has not been performed for vector control

Vector control will not perform if autotuning has not been performed. Perform autotuning, or set the motor constants through calculations. Alternatively, change the Control Method Selection (A1-02) to V/f control (0 or 1).

If There is Noise When the Inverter is Started or From an AM Radio

If noise is generated by Inverter switching, implement the following countermeasures:

• Change the Inverter's Carrier Frequency Selection (C6-02) to lower the carrier frequency. This will help to some extent by reducing the amount of internal switching.

•

Install an Input Noise Filter at the Inverter's power supply input area.

Install an Output Noise Filter at the Inverter's power supply output area.

Use metal tubing. Electric waves can be shielded by metal, so encase the Inverter with metal (steel).

Ground the Inverter and motor.

Separate main circuit wiring from control wiring.

If the Ground Fault Interrupter Operates When the Inverter is Run

The Inverter performs internal switching, so there is a certain amount of leakage current. This may cause the ground fault interrupter to operate and cut off the power supply. Change to a ground fault interrupter with a high leakage detection level (i.e., a sensitivity current of 200 mA or greater per Unit, with an operating time of

0.1 s or more), or one that incorporates high frequency countermeasures (i.e., one designed for use with Inverters). It will also help to some extent to change the Inverter's Carrier Frequency Selection (C6-02) to lower the carrier frequency. In addition, remember that the leakage current increases as the cable is lengthened.

If There is Mechanical Oscillation

Use the following information when there is mechanical oscillation.

The machinery is making unusual sounds.

The following causes are possible.

There may be resonance between the mechanical system's characteristic frequency and the carrier frequency.

If the motor is running with no problems and the machinery is oscillating with a high-pitched whine, it may indicate that this is occurring. To prevent this type of resonance, adjust the carrier frequency with constants

C6-02 to C6-05.

There may be resonance between a machine's characteristic frequency and the output frequency of the Inverter.

To prevent this from occurring, either use the jump frequency functions in constants d3-01 to d3-04 or install rubber padding on the motor base to reduce oscillation.

Troubleshooting

Oscillation and hunting are occurring with open-loop vector control.

The gain adjustment may be insufficient. Reset the gain to a more effective level by adjusting constants C4-02

(torque compensation time constant), C2-01 (S-curve Characteristic Time at Acceleration Start), and C3-02

(Slip Compensation Primary Delay Time) in order. Lower the gain setting and raise the primary delay time setting.

Vector control will not perform if autotuning has not been performed. Perform autotuning separately for the motor, or set the motor constants through calculations. Alternatively, change the control method selection (A1-

02) to V/f control (0 or 1).

Oscillation and hunting are occurring with V/f control.

The gain adjustment may be insufficient. Reset the gain to a more effective level by adjusting constants C4-02

(Torque Compensation Primary Delay Time Constant), N1-02 (Hunting Prevention Gain), and C3-02 (Slip

Compensation Primary Delay Time) in order. Lower the gain setting and raise the primary delay time setting.

Oscillation and hunting are occurring with V/f w/PG control.

The gain adjustment may be insufficient. Adjust the various types of speed control loop (ASR) gain.

If the oscillation cannot be eliminated in this way, set the hunting prevention selection (constant N1-01) to 0

(disabled) and then try adjusting the gain again.

Oscillation and hunting are occurring with flux vector control.

The gain adjustment is insufficient. Adjust the various gains for speed control (ASR). If the oscillation points overlap with those of the machine and cannot be eliminated, increase the primary delay time constant for speed control (ASR) in C5-06 and then readjust the gains.

If autotuning is not performed, proper performance cannot be achieved for vector control. Perform autotuning or set the motor constants according to calculations.

Oscillation and hunting are occurring with PID control.

If there is oscillation or hunting during PID control, check the oscillation cycle and individually adjust P, I, and D constants. (Refer to page 6-112.)

Autotuning has not been performed with vector control.

(A1-02) to V/f control.

If the Torque Generated for the Motor is Insufficient (Insufficient Power)

If autotuning has not been performed, or the control method has been changed since last performing autotuning, perform autotuning. If the problem occurs after performing stationary autotuning, perform rotational autotuning.

-26

If the Motor Rotates Even When Inverter Output is Stopped

If the motor rotates even when the Inverter output is stopped, the DC injection braking is insufficient. If the motor continues operating at low speed, without completely stopping, and after a deceleration stop has been executed, it means that the DC injection braking is not decelerating enough. Adjust the DC injection braking as follows:

•

Increase the constant b2-02 (DC Injection Braking Current) setting.

Increase the constant b2-04 (DC Injection Braking (initial excitation) Time at Stop) setting.

If OV is Detected When the Fan is Started, or Fan Stalls

Generation of OV (main circuit voltage) and stalling can occur if the fan is turning when it is started. The DC injection braking is insufficient when starting.

This can be prevented by slowing fan rotation by DC injection braking before starting the fan. Increase the constant b2-03 (DC injection braking time (initial excitation) at start) setting.

If Output Frequency Does Not Rise to Frequency Reference

Use the following information if the output frequency does not rise to the frequency reference.

The frequency reference is within the jump frequency range.

When the jump frequency function is used, the output frequency does not change within the jump frequency range. Check to be sure that the Jump Frequency (constants d3-01 to d3-03) and Jump Frequency Width (constant d3-04) settings are suitable.

The frequency reference upper limit has been reached.

The output frequency upper limit is determined by the following formula:

Maximum Output Frequency (E1-04) × Frequency Reference Upper Limit (d2-01) / 100

Check to be sure that the constant E1-04 and d2-01 settings are suitable.

Application Function Precautions

Observe the following precautions when using the application functions.

• Perform rotational autotuning during trial operation whenever it is possible to separate the motor and machine. To achieve the characteristics of vector control described in Table 10.1

, the control must be adjusted within a range that the machine will not vibrate after rotational autotuning has been performed.

•

With vector control, the motor and Inverter must be connected 1:1. Vector control is not possible when multiple motors are connected to a single Inverter. Select an Inverter capacity so the rated motor current is

50% to 100% of the rated Inverter current.

For estimated speed searching, the motor and Inverter must be connected 1:1. The speed search must be performed at a frequency of 130 Hz or less and with a motor with the same number of frames as or one frame less than the Inverter capacity.

•

During high-slip braking, motor loss increases, so use a high-slip braking frequency of 5% ED or less, and a braking time of 90 seconds or less. Once high-slip braking has started, the motor cannot be restarted until it has stopped.

Feed forward control is a function that improves the proportional gain of the motor speed in relation to the change in the speed reference. Adjust the response to interference loads using the speed controller (ASR) constants.

The torque limit function will not operate during acceleration or deceleration (during soft start transition) when using a control method such as open-loop vector control. Even if the motor speed drops due to torque limiting while set to a fixed speed, the speed will not fall below the minimum frequency and the motor will not slip into reverse rotation.

Control Methods and Applications

Application examples for the Inverter control methods are provided here.

V/f Control (A1-02 = 0)

Inverter Application Precautions

This section provides precautions for selecting, installing, setting, and handling Inverters.

Selection

Observe the following precautions in selecting an Inverter.

Installing Reactors

A large peak current will flow in the power input circuit when the Inverter is connected to a large-capacity power transformer (600 kVA or higher) or when switching a phase advancing capacitor. Excessive peak current can destroy the convertor section. To prevent this, install a DC or AC reactor (optional) to improve the power supply power factor.

DC reactors are built into 200 V Class Inverters of 22 to 110 kW and 400 V Class Inverters of 22 to 300 kW.

If a thyristor convertor, such as a DC drive, is connected in the same power supply system, connect a DC or

AC reactor regardless of the power supply conditions shown in the following diagram.

Power supply capacity (kVA)

DC or AC reactor

Required

DC or AC reactor

Not required

Inverter capacity (kVA)

Fig 10.5

Inverter Capacity

When connecting special motors or multiple motors in parallel to an Inverter, select the Inverter capacity so that the rated output current of the Inverter is 1.1 times the sum of all the motor rated currents.

Applications with Repetitive Loads

Applications with repetitive loads (cranes, elevators, presses, washing machines, etc.) using Inverters require derating for the repetitive load [reducing carrier frequency and current (changing accel/decel timing, increasing the frame size of the Inverter)]. Contact your Yaskawa representative for details.

Initial Torque

The startup and acceleration characteristics of the motor are restricted by the overload current ratings of the

Inverter that is driving the motor. The torque characteristics are generally less than those required when starting using a normal commercial power supply. If a large initial torque is required, select an Inverter with a somewhat larger capacity or increase the capacity of both the motor and the Inverter.

Emergency Stop

Although the Inverter's protective functions will stop operation when a fault occurs, the motor will not stop immediately. Always provide mechanical stop and protection mechanisms on equipment requiring an emergency stop.

Inverter Application Precautions

Options

Terminals B1, B2, , 1, 2, 3 are for connecting only the options specifically provided by Yaskawa.

Never connect any other devices to these terminals.

Installation

Observe the following precautions when installing an Inverter.

Installation in Enclosures

Either install the Inverter in a clean location not subject to oil mist, air-bourne matter, dust, and other contaminants, or install the Inverter in a completely enclosed panel. Provide cooling measures and sufficient panel space so that the temperature surrounding the Inverter does not go beyond the allowable temperature. Do not install the Inverter on wood or other combustible materials.

Installation Direction

Mount the Inverter vertically to a wall or other horizontal surface.

Settings

Observe the following precautions when making settings for an Inverter.

Upper Limits

The Digital Operator can be used to set high-speed operation up to a maximum of 400 Hz (depends on the carrier frequency). Incorrect settings can be dangerous. Use the maximum frequency setting functions to set upper limits. (The maximum output frequency is factory-set to 60 Hz.)

DC Injection Braking

The motor can overheat if the DC injection braking voltage or braking time is set to a large value.

Acceleration/Deceleration Times

The motor's acceleration and deceleration times are determined by the torque generated by the motor, the load torque, and the load's inertial moment (GD

/4). If the stall prevention functions are activated during acceleration or deceleration, increase the acceleration or deceleration time. The stall prevention functions will increase the acceleration or deceleration time by the amount of time the stall prevention function is active.

To reduce the acceleration or deceleration times, increase the capacity of the motor and Inverter.

Handling

Observe the following precautions when wiring or performing maintenance for an Inverter.

10-

-8

Wiring Check

The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W.

Check wring for any mistakes before supplying power. Check all wiring and sequences carefully.

Magnetic Contactor Installation

Do not start and stop operation frequently with a magnetic contactor installed on the power supply line. Doing so can cause the Inverter to malfunction. Do not turn the Inverter ON and OFF with a magnetic contactor more than one time every 30 minutes.

Setting the Power Supply Voltage Jumper (400 V Class Inverters of 75 kW or higher)

If the jumper is inserted into a power tap that does not match the actual power supply voltage, the lifetime of the transformer for the power supply or the wind capacity of the cooling fan may be reduced.

If the jumper is inserted and the voltage setting is too low for the actual power supply, a power surge may occur on the transformer for the power supply and reduce the lifetime of the transformer.

If the jumper is inserted and the voltage setting is too high for the actual power supply, the wind capacity of the cooling fan is reduced.

Insert the jumper into the power tap with the voltage setting nearest to the voltage of the actual power supply.

Refer to Chapter 4 Trial Operation for the procedure.

Maintenance and Inspections

After turn OFF the main circuit power supply, always confirm that the CHARGE indicator is not lit before performing maintenance or inspections. The voltage remaining in the capacitor may cause electric shock.

Motor Application Precautions

This section provides precautions for motor application.

Using the Inverter for an Existing Standard Motor

When a standard motor is operated with the Inverter, power loss is slightly higher than when operated with a commercial power supply. Observe the following precautions when using an Inverter for an existing standard motor.

Low Speed Ranges

Cooling effects diminish in the low-speed range, resulting in an increase in the motor temperature. Therefore, the motor torque should be reduced in the low-speed range whenever using a motor not made by Yaskawa. If

100% torque is required continuously at low speed, consider using a special Inverter or vector motor.

Installation Withstand Voltage

If the input voltage is high (440 V or higher) or the wiring distance is long, the motor insulation voltage must be considered. Contact your Yaskawa representative for details.

High-speed Operation

When using the motor at a high speed (60 Hz or more), problems may arise in dynamic balance and bearing durability. Contact your Yaskawa representative for details.

Torque Characteristics

The motor may require more acceleration torque when the motor is operated with the Inverter than when operated with a commercial power supply. Check the load torque characteristics of the machine to be used with the motor to set a proper V/f pattern.

Vibration

The Inverter uses a high carrier PWM to reduce motor vibration. (A constant can be set to select low carrier,

PWM modulation control as well.) The factory setting of the Inverter with SPEC: C or earlier is for a high carrier PWM and the one with SPEC: E or later is for a low carrier PWM. When the motor is operated with the

Inverter that uses a high carrier PWM, motor vibration is almost the same as when operated with a commercial power supply.

Motor vibration may, however, become greater in the following cases.

Resonance with the Natural Frequency of the Mechanical System

Take special care when a machine that has been operated at a constant speed is to be operated in variable speed mode. If resonance occurs, install vibration-proof rubber on the motor base or use the frequency jump function to skip any frequency resonating the machine.

Imbalanced Rotor

Take special care when the motor is operated at a higher speed (60 Hz or more).

10-

Noise

Noise varies with the carrier frequency. At high carrier frequencies, the noise is almost the same when the motor is operated with a commercial power supply. Motor noise, however, becomes louder when the motor is operated at a speed higher than the rated speed (60 Hz).

Using the Inverter for Special Motors

Observe the following precautions when using a special motor.

Pole-changing Motor

The rated input current of pole-changing motors differs from that of standard motors. Select, therefore, an appropriate Inverter according to the maximum input current of the motor to be used. Before changing the number of poles, always make sure that the motor has stopped. Otherwise, the overvoltage protective or overcurrent protective mechanism will be actuated, resulting in an error.

Submersible Motor

The rated input current of submersible motors is higher than that of standard motors. Therefore, always select an Inverter by checking its rated output current. When the distance between the motor and Inverter is long, use a cable thick enough to connect the motor and Inverter to prevent motor torque reduction.

Explosion-proof Motor

When an explosion-proof motor is to be used, it must be subject to an explosion-proof test in conjunction with the Inverter. This is also applicable when an existing explosion-proof motor is to be operated with the Inverter.

Since the Inverter itself is, however, not explosion-proof, always install it in a safe place.

Gearmotor

The speed range for continuous operation differs according to the lubrication method and motor manufacturer.

In particular, continuous operation of an oil-lubricated motor in the low speed range may result in burning. If the motor is to be operated at a speed higher than 60 Hz, consult with the manufacturer.

Synchronous Motor

A synchronous motor is not suitable for Inverter control. If a group of synchronous motors is individually turned ON and OFF, synchronism may be lost.

Single-phase Motor

Do not use an Inverter for a single-phase motor. The motor should be replaced with a 3-phase motor.

-10

Power Transmission Mechanism (Speed Reducers, Belts, and Chains)

If an oil-lubricated gearbox or speed reducer is used in the power transmission mechanism, oil lubrication will be affected when the motor operates only in the low speed range. The power transmission mechanism will make noise and experience problems with service life and durability if the motor is operated at a speed higher than 60 Hz.

Conformance to UL Standard

To comply with UL standard, follow the appropriate installation instructions.

Installation Site

Install the Inverter in a pollution degree 2 environment or equivalent.

Specification of Closed-Loop Connector

The closed-loop connectors must be installed on conductors before installing to terminal blocks.

Use JST or equivalent closed-loop connectors shown below.

600 VAC maximum.

Motor Overheat Protection

To protect the motor from overheating, set the E2-01 constant in the Inverter to the same value as the level of the motor rated current.

Conformance to CE Markings

Points regarding conformance to CE markings are given below.

CE Markings

CE markings indicate conformance to safety and environmental standards that apply to business transactions

(including production, imports, and sales) in Europe. There are unified European standards for mechanical products (Machine Directive), electrical products (Low Voltage Directive), and electrical noise (EMC Directive). CE markings are required for business transactions in Europe (including production, imports, and sales).

The Varispeed F7-Series Inverters bear CE markings indicating conformance to the Low Voltage Directive and the EMC Directive.

•

Low Voltage Directive: 73/23/EEC

93/68/EEC

EMC Directive: 89/336/EEC

92/31/EEC

Machinery and installations that incorporate the Inverter are also subject to CE markings. It is ultimately the responsibility of customers making products incorporating the Inverter to attach CE markings to the finished products. The customer must confirm that the finished products (machines or installations) conform to the

European Standards.

Requirements for Conformance to CE Markings
