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.
• The IPM motor is a synchronous motor with high-performance magnets mounted in the rotor.
Unlike the induction motor, high motor-terminal voltage is generated while the motor is running, even when the Inverter power is OFF. Maintenance, inspection, or wiring must be done while the motor is stopped.
Failure to observe this warning may result in an electric shock.
• For applications where the overhauling load causes the motor to turn even when the Inverter power is OFF, be sure to connect a low-voltage manual starter on the Inverter's output side.
Failure to observe this warning may result in an electric shock.

CAUTION
• Motors of any other type, such as induction motors, can be connected only in the sequence test mode (A1-02=0). This Inverter is used exclusively for IPM motor drives.
Failure to observe this caution may result in damage to the Inverter or the motors.
• If connecting a motor in the sequence test mode (A1-02=0), the motor must be separated from the load (machine, equipment, etc).
Failure to observe this caution may result in injury or damage to the product.
• 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 and the Inverter, braking resistors, Braking Resistor Units, and Braking Units can be damaged.
• 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 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.
• Do not ground nor connect the AC terminal on the control circuit to the unit.
Doing so may result in a malfunction or a breakdown of the Inverter.
Setting User Constants
CAUTION
• Disconnect the load (machine, device) from the motor before performing PG home position offset.
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 until PG home position offset has been successfully completed.
The motor could stop and then start again unexpectedly and this could result in injury.
• Always confirm the following before PG home position offset:
• The lock key has been removed from the motor shaft.
• There are neither people nor objects around the motor shaft.
• The motor is at a complete stop.
Failure to do so may result in injury.
• Be careful when handling the shaft and coupling.
Failure to do so may result in injury.
• Be careful not to injure yourself with the key groove when turning the motor shaft by hand.
Failure to do so may result in injury.
• For an initial operation or the first operation after replacing the Inverter or the motor, correctly set the motor constants. Then, be sure to double check if the settings were correctly made.
If the settings are incorrect, the overhauling load might cause the motor to turn because of insufficient torque, or the motor might not run in accordance with an issued command (reverses, does not move, or shortly accelerates).
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. For the
Inverters in the 400 V class of 75 kW or more, however, select the correct connector according to the input voltage.
Otherwise, the equipment may be damaged.
• For the initial operation or the first operation after replacing the motor, set the motor constants before starting operation. Also, reconfirm the motor constants after they have been set.
Improper setting may cause the Inverter to malfunction. Failure to observe this caution may result in damage to the equipments, motors or Inverter.
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.

WARNING
• Maintenance or inspection must be done while the motor is stopped.
Failure to observe this warning may result in an electric shock.
• Do not carry out maintenance or inspections for at least 5 minutes after the low-voltage manual switching device on the output side is turned OFF.
Because the IPM motor contains a permanent magnet, voltage occurs between the terminals during rotation even if power is not applied. This voltage is dangerous and may cause electric shock.
• 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.
• Provide a separate holding brake if necessary.
Always make any adjustments other than those involving the operation of the Inverter with the holding brake released.
Failure to observe this caution may 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.
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.

TERMS
Open Chassis Type (IEC IP00)
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.

Protection covers are attached to the top and bottom of the Inverter. Be sure to remove the protection covers before installing a 200 or 400 V Class Inverter with an output of 18.5 kW or less in a panel. Refer to Page 1-17 on how to remove the protection covers.
Observe the following precautions when mounting the Inverter.
• Install the Inverter in a clean location free from oil mist and dust. It can be installed in a totally enclosed panel that is completely shielded from floating dust.
•
•
•
When installing or operating the Inverter, always take special care so that metal powder, oil, water, or other foreign matter does not get into the Inverter.
Do not install the Inverter on combustible material, such as wood.
Install the Inverter in a location free from radioactive materials and combustible materials.
•
•
•
•
Install the Inverter in a location free from harmful gasses and liquids.
Install the Inverter in a location without excessive oscillation.
Install the Inverter in a location free from chlorides.
Install the Inverter in a location not in direct sunlight.
Controlling the Ambient Temperature
To enhance the reliability of operation, the Inverter should be installed in an environment free from extreme temperature increases. If the Inverter is installed in an enclosed environment, such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 45 ° C.
Protecting the Inverter from Foreign Matter
Place a cover over the Inverter during installation to shield it from metal powder produced by drilling.
Always remove the cover from the Inverter after completing installation. Otherwise, ventilation will be reduced, causing the Inverter to overheat.
Installation Orientation and Space
Installation Orientation and Space
Install the Inverter vertically so as not to reduce the cooling effect. When installing the Inverter, always provide the following installation space to allow normal heat dissipation.

2. The output current capacity of the +V and − V terminals are 20 mA. Do not short-circuit between the +V, − V, and AC terminals. Doing so may result in a malfunction or a breakdown of the Inverter.
3. Disable the overvoltage inhibit selection during deceleration (set constant L3-11 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-X2 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 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 75 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.
13.Do not ground nor connect the AC terminal on the control circuit to the unit. Doing so may result in a malfunction or a breakdown of the Inverter.

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.

Fig 2.5 Main Circuit Terminal Connections
Wiring Main Circuit Terminals
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
120% 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
.

200 to 240 VAC, 50/60 Hz
2037 to 2075: 3-phase,

40P4 to 4300: 3-phase,
380 to 460 VAC, 50/60 Hz
Power supply
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. At the Inverter primary side, use a ground fault interrupter for Inverters with a countermeasure against high frequency to detect only the leakage current in the frequency range that is hazardous to humans and to ignore high-frequency leakage current. Use one or several ground fault interrupters with a total cumulative sensitivity amperage of at least 30 mA per Inverter.
Using a ground fault interrupter without a countermeasure against high frequency may result in a malfunction caused by high-frequency leakage current. If a ground fault interrupter without a countermeasure malfunctions, replace it with a ground fault interrupter with a countermeasure against high frequency or reduce the carrier frequency of the Inverter. Alternatively, use one or several ground fault interrupters with a total cumulative sensitivity amperage of at least 200 mA per Inverter.
2-

-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.

Do not use general-purpose noise filters. No generalpurpose noise filter can effectively suppress noise generated from the Inverter.
Fig 2.8 Incorrect Power supply Noise Filter Installation
Do not use a Phase Advancing Capacitor
If a phase advancing capacitor or a surge absorber is connected to the input side of the inverter’s main circuit to improve the power factor, harmonics from the inverter may cause overheating or damage the phase advancing capacitor or the surge absorber. Also, the inverter may malfunction because of the overcurrent.
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.
Installing a Low-voltage Manual Starter
For applications where the overhauling load causes the motor to turn even when the Inverter power is OFF, be sure to connect a low-voltage manual starter on the Inverter’s output side. Be sure to open the low-voltage manual starter when wiring and during maintenance and inspection of the Inverter.
E.g.: AICUT LB Series manufactured by AICHI ELECTRIC CO., LTD.
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.
Do Not Switch the Magnetic Starter (Contactor) ON/OFF during Operation
Usually, a magnetic starter should not be connected between the Inverter and the motor. If a magnetic starter must be installed between the Inverter and the motor, never switch ON (close) or OFF (open) during operation, except during an emergency. Confirm that an inverter baseblock has occurred before turning the magnetic starter ON (close) or OFF (open). If the magnetic starter is turned ON (close) or OFF (open) while the
Inverter is running and not during a baseblock, an Inverter fault may occur. For example, a large inrush current could flow and activate the Inverter overcurrent protection.
Note The condition of the Inverter baseblock can be checked with the baseblock signal of the multi-function contact output. For details, refer to the User
Constant Tables in Chapter 5.
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.

Radio Noise:
Electromagnetic induction generates noise on the signal line, causing the controller to malfunction.
Electromagnetic waves from the Inverter and cables cause the broadcasting radio receiver to make noise.
Fig 2.9 Installing a Noise Filter on the Output Side
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 or motor operations. 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 .)
Cable length
Carrier frequency

100 m max.
8 kHz max.
More than 100 m
4 kHz max.
Note With open-loop vector control for PM (A1-02 = 7), the maximum length of the cable between the Inverter and the motor is 100 m, and the maximum carrier frequency is 4 kHz. If not, the performance of the motor might be abnormal.
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.

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.
Table 2.8
L8-01 (Protect selection for internal DB resistor) 0 (Disables overheat protection)
L3-11 (Overvoltage inhibit selection) 0 (Disables overvoltage inhibit selection)
L8-01 is used when a braking resistor without thermal overload relay trip contacts (ERF type mounted to
Inverter) is connected.
When using the braking resister unit, set L3-11 (Overvoltage inhibit selection) to 0 (Disabled). If L3-11 is not set to 0, the inverter might not stop within the set deceleration time.
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

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.

Trial Operation Procedures
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).
However, only 1(VT) can be set for 400 V Class 220 kW and 300 kW Inverters with any SPEC.
Note: Inverters with SPEC: B or earlier are used only for applications requiring variable torque.
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. If the wrong connector is selected, the Inverter may be damaged.
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.

400V Class: 3-phase 380 to 480 VAC 50/60 Hz
For an Inverter of 200 V, 37 kW or more, use one of the following power supplies for the cooling fan.
3-phase 200/208/220 VAC 50 Hz or 3-phase 200/208/220/230 VAC 60 Hz
2. Make sure that the motor output terminals (U, V, W) and the motor are connected correctly.
3. Make sure that the Inverter control circuit terminal and the control device are wired correctly.
4. Set all Inverter control circuit terminals to turn OFF.
5. When using a PG speed control board, make sure that it is wired correctly.
6. Make sure that the motor is not connected to the mechanical system. (No-load condition)
Checking the Display Status
If the Digital Operator's display at the time the power is connected is normal, it will read as follows:
Display for normal operation
The speed reference ( % ) monitor is displayed in the data display section.

E.g.: When using a motor with a base speed (E1-06) of 1750 min -1 and a capacity of 0.4 kW within a fixed
output range of 1: 1.5, use the following equation to calculate the setting of E1-04 (Max. motor speed):
E1-04=E1-06 × 1.5.
Trial Operation Procedures
2. Selection of the Rotational Direction of Motor
Select the direction of the motor rotation in F1-05 (PG rotation).
The factory setting of F1-05 is 1 (phase B leads with forward run command).
A forward run is when the motor rotates counterclockwise (CCW) as viewed from the load side. If using a forward run in which the motor rotates clockwise (CW) as viewed from the load side, use the following procedures.
Step1. Rewire the cables between the motor and the Inverter.
Switch the cables to any two of the U, V, or W output terminals.
For example, if the terminals are connected in the order of U, V, and W, then switch the cables of terminal V and W and reconnect them in the order of U, W, and V.
Step2. Change the settings of Inverter constants.
• PG rotation (F1-05)
Change the setting from 1 [phase B leads with forward run command
•
(CCW)]to 0 [phase A leads with forward run command (CW)].
PG home position offset (E5-11)
Multiple the preset value by negative one and set E5-11 to the resulting value.
For example, if the PG home position offset has already been done, then multiply the value set automatically as PG home position by negative one and set E5-11 to the resulting value.
3. Confirmation of the Rotational Direction of Motor
Follow the procedure outlined in Table 4.7 to view the detected motor speed, and check the following two points.
•
•
When manually rotating the motor shaft, check if the actual rotational direction is in accordance with the displayed polarity .
Check if the displayed motor speed is correct.
IMPORTANT
• After confirming that the STOP LED of the Digital Operator is lit, check the rotational direction of the motor.
• Be careful not to get anything caught in the shaft or coupling.
• When manually rotating the coupling, be careful not to hurt yourself with the key slot.

U1-05 will change from 0.00 % to
3.00%.
Check if the displayed motor speed is a positive value for a forward run and if it is as appropriate as the rotating speed.
Confirmation
If the direction of the forward run is counterclockwise (CCW), rotate the motor shaft clockwise as viewed from the load side.
U1-05 will change from 0.00% to -
3.00%.
W If the direction of the forward run is clockwise (CW), rotate the motor shaft counterclockwise as viewed from the load side.
Check if the displayed motor speed is a negative value for a reverse run and if it is as appropriate as the rotating speed.
If an error was found when checking the motor rotation, correct the problem by carrying out the recommended course of action listed.
Error
Shows motor speed for opposite polarity.
Action
Change the setting for PG rotation (F1-05).
Shows incorrect motor speed or zero.
Check the PG wiring.
Refer to Wiring the PG-X2 in Chapter 2.
4. Compensation of the Zero-point Pulse of PG
Use autotuning to compensate for the zero-point pulse of a PG.
[Precautions before Autotuning]
Check the following precautions before starting autotuning.
• Autotuning of the Inverter is fundamentally different from that of the servo system. Inverter autotuning automatically adjusts the constants according to the values of the detected motor constants, whereas servosystem autotuning adjusts the constants according to the detected size of the load.
•
•
•
If autotuning is done with the motor connected to the load, the motor constants that are obtained will be incorrect and the motor may operate in an unusual manner. Be sure to separate the motor from the load before starting autotuning.
During autotuning, the required data will be measured while the motor is running, so, make sure that the motor is ready to run before starting autotuning. If a switch is installed between the motor and the Inverter, be sure to shut off the switch before autotuning.
Multi-function analog input terminals do not work during autotuning. Also, multi-function analog output terminals maintain their status that existed before autotuning was started.
Trial Operation Procedures
[Operation Procedure for Autotuning]
1. In autotuning mode, set the constant for autotuning mode selection (T1-01) to 4 (PG home position offset and line-to-line resistance autotuning).
2. Refer to the nameplate of the motor for setting the following constants in the order in which they are displayed on the digital operator: motor rated capacity, base speed, base voltage, motor rated current, number of motor poles, motor d-axis inductance, motor q-axis inductance, and motor induced voltage.
3. Set T2-11 (Input voltage setting) to the Inverter input current in accordance with the power supply voltage being used.
4. After setting all of the constants, press the RUN key. Automatic measurements used to calculate the compensation value of the zero-point pulse using a PG and the value of the motor armature resistance will start.

Trial Operation Procedures
[Precautions after Autotuning]
• When autotuning is completed
The measured compensation value of zero-point pulse using a PG will be copied to E5-11 (PG home position offset).
The measured armature resistance will be copied to E5-05 (Motor armature resistance).
The setting of T2-01 to T2-11 after autotuning will be reflected to the corresponding constants in Constant
Settings for Autotuning in page 4-14.
•
If the maximum speed and the base speed differ, set E1-04 (Max. motor speed) after completion of autotuning. For the upper setting limit of E1-04, refer to Table 4.6 The Allowable Range of Fixed Output in page 4-10.
When autotuning is halted
If an error occurs during autotuning, autotuning will be halted. Neither the measured value nor the set value will be copied to the constants. The settings will return to be their pre- autotuning values.
Refer to Chapter 7 Troubleshooting and take corrective action. After doing so, once again implement PG home position offset and line-to-line resistance autotuning.
Open-loop vector control for PM (A1-02 = 7)
Motor constant setting has two patterns. Set the motor constants by either manual setting or autotuning mode setting.
Check the nameplate (NP) of the motor being used for the motor constant values.
Fill those values in the NP Value (Setting) columns of Table 4.9.

2. Autotuning Mode Setting Procedure
Set the motor constants by autotuning.
[Precautions before Autotuning]
Check the following precautions before starting autotuning.
• Autotuning of the Inverter is fundamentally different from that of the servo system. Inverter autotuning automatically adjusts the constants according to the values of the detected motor constants, whereas servosystem autotuning adjusts the constants according to the detected size of the load.
•
•
•
If autotuning is done with the motor connected to the load, the motor constants that are obtained will be incorrect and the motor may operate in an unusual manner. Be sure to separate the motor from the load before starting autotuning.
If a switch is installed between the motor and the Inverter, be sure to shut off the switch before autotuning.
Multi-function analog input terminals do not work during autotuning. Also, multi-function analog output terminals maintain their status that existed before autotuning was started.
[Operation Procedure for Autotuning]
1. Set the motor capacity selection (E5-01). If using a 1750 min -1 motor, setting is not required. (Refer to
Table 4.9.)
2. In autotuning mode, set the constant for autotuning mode selection (T1-01) to 2 (Stationary autotuning for line-to-line resistance only).
3. Refer to the nameplate of the motor for setting the following constants in the order in which they are displayed on the digital operator: motor rated capacity, base speed, base voltage, motor rated current, number of motor poles, motor d-axis inductance, motor q-axis inductance, and motor induced voltage.
4. Set T2-11 (Input voltage setting) to the Inverter input current in accordance with the power supply voltage being used.
5. After setting all of the constants, press the RUN key. Automatic measurements will start to calculate the value of the motor armature resistance.

[Precautions after Autotuning]
• When autotuning is completed
The measured armature resistance will be copied to E5-05 (Motor armature resistance).
The setting of T2-01 to T2-11 after autotuning will be reflected to the corresponding constants in Constant
Settings for Autotuning in page 4-21.
If the maximum speed and the base speed differ, set E1-04 (Max. motor speed) after completion of autotuning. For the upper setting limit of E1-04, refer to Table 4.11 The Allowable Range of Fixed Output in page 4-19.
• When autotuning is halted
If an error occurs during autotuning, autotuning will be halted. Neither the measured value nor the set value will be copied to the constants. The settings will return to be their pre- autotuning values.
Refer to Chapter 7 Troubleshooting and take corrective action. After doing so, once again implement lineto-line resistance autotuning.
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 1750 min -1 motor by 10%, set E1-04 to 1925 min -1 .
To use a 0 to 10-V analog signal for a 1750 min -1 motor for variable-speed operation between 0 to 1575 min -1 (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%.
Change the setting of L3-11 to 0 (Overvoltage inhibit selection disabled) to decrease the speed using a braking unit or braking resister.
To enable use with an increased safety, explosion-proof model in the variable torque series of IPM motors, change the setting of L1-01 to 6 [Increased safety, explosion-proof PM motor (variable torque)].
Trial Operation Procedures
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: 10.00%) 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.
INFO
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).
If a fault caused by braking characteristics, such as hunting or oscillation, occurs during no-load operation, refer to page
4-27 Adjustment Suggestions and make adjustments.
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.
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 speed 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 speed reference.
After changing the speed 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 4-27 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.

2. A value less than the setting of El-09 (Min. speed) cannot be set for speed references. If you are having trouble setting the speed reference, check the setting of El-09.
* If the display unit is Hz, the setting ranges change. For open-loop/flux vector control or vector control with a PG for PM, the upper limits of the setting would be calculated by the following formula: E1-09 × E5-04 ÷ 120.
For sequence test, the upper limits of the setting would be E1-09.

Difference Between CT and VT
The characteristics of CT (low carrier, constant torque) and VT (high carrier, variable torque) are shown below.
CT: Low Carrier, Constant Torque VT: High Carrier, Variable Torque
Constant 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.

Setting Precautions
C6-01 (CT/VT Selection)
When setting C6-01, observe the following precautions.
• Depending on the set value in C6-01, the setting range of the related constants is limited as follows:
C6-01 Set Value
Inverter Overload Protection Level
C6-02 (Carrier Frequency Selection)
0 (Low Carrier, Constant
Torque)
150% Inverter rated current/1 min.
1: Carrier 2.0 kHz
1 (High Carrier, Variable
Torque)
120% Inverter rated current/1 min.
1: Carrier 2.0 kHz
*
2: Carrier 4.0 kHz
3: Carrier 6.0 kHz
4: Carrier 8.0 kHz
6: Carrier 12.0 kHz
* The factory setting vary in accordance with the control method and the Inverter capacity.
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 (12 kHz) 0 to 4 (8 kHz) 0 to 2 (4 kHz)
Note With open-loop vector control for PM (A1-02 = 7), the maximum length of the cable between the Inverter and the motor is 100 m, and the maximum carrier frequency is 4 kHz. If not, the performance of the motor might be abnormal.
•
•
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.
For applications with repetitive loads (cranes, elevators, presses, washing machines, etc.), if a current exceeding 125% of the Inverter rated current or more flows repeatedly, the IGBT in the Inverter will be subject to heat stress, resulting in a shortened life span. In this case, select CT instead of VT and reduce the load, lengthen the acceleration/deceleration time, or increase the frame size of the Inverter so that the peak current for repetitive operation will drop to less than 125% of the Inverter rated current. If performing a trial operation with repetitive loads, make sure that the peak current for repetitive operation is less than
125% of the Inverter rated current.
If particularly low noise is not required, do not increase the Inverter’s carrier frequency to reduce the influence of heat stress.
Carrier frequency upper limit depends on the Inverter capacity. Refer to Factory Settings that Change with the
Inverter Capacity (o2-04) on page 5-70.

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 motor speed when decelerating to a stop falls below b2-01, the baseblock will be applied.

Acceleration and Deceleration Characteristics
This section explains the acceleration and deceleration characteristics of the Inverter.
Setting Acceleration and Deceleration Times
Acceleration time indicates the time taken for the motor speed (output frequency) to climb from 0% to 100% of maximum speed. Deceleration time indicates the time taken for the motor speed (output frequency) to reduce from 100% to 0% of maximum speed. The factory setting of the acceleration time is C1-01, and the factory setting of the deceleration time is C1-02.

Switching Acceleration and Deceleration Time Using Multi-Function Input Terminal
Commands
Using the Inverter, you can set four acceleration times and four deceleration times. When the multi-function input terminals (H1 ) are set to 7 (acceleration/deceleration time selection 1) and 1A (acceleration/deceleration time selection 2), you can switch the acceleration/deceleration time even during operation by combining the ON/OFF status of the terminals.

Switching Acceleration and Deceleration Time Automatically
Use this setting when you want to switch acceleration/deceleration time automatically using the set speed.
When the motor speed (output frequency) reaches the set value in C1-11, the Inverter switches the acceleration/deceleration time automatically as shown in the following diagram.
Set C1-11 to a value other than 0.0%. If C1-11 is set to 0.0%, the function will be disabled.

When motor speed (output frequency) ≥ C1-11, acceleration and deceleration are performed using Acceleration/deceleration Time 1 (C1-01, C1-02).
When motor speed (output frequency) < C1-11, acceleration and deceleration are performed using Acceleration/deceleration Time 4 (C1-07, C1-08).
Fig 6.19 Acceleration/deceleration Time Switching Speed
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
Acceleration/deceleration time gain (set value: 5)
(Acceleration/deceleration gain from 1 to
10 V) = 10 V/Input voltage (V) x 10 (%)

Acceleration and Deceleration Characteristics
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

Acceleration and Deceleration Characteristics
Preventing Overvoltage During Run
The overvoltage inhibit function automatically reduces the regenerative torque limit to suppress the voltage rise of the DC bus, if the voltage rises while the motor is running. While the motor is decelerating, the deceleration time will be automatically set to a longer time, and then the actual deceleration time may be longer than the set value.

If using a braking option, such as the braking resister, braking resister units, or braking units, set L3-11 to
0. If L3-11 is not set to 0, the motor may not stop within the preset allowable deceleration time.
The overvoltage inhibit function automatically adjusts the deceleration rate based on the set value of E1-01
(Input voltage setting). So, make sure that E1-01 is correctly set in accordance with the supply voltage. If not, the motor may not stop, depending on the conditions of the supply voltage.

The jump speed function operates the motor while avoiding resonance caused by characteristic speeds in the machinery.
This function is effective in creating a speed reference dead band.
During constant-speed operation, operation within the jump speed range is prohibited. Smooth operation still used during acceleration and deceleration, i.e., jumps are not performed.

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 motor speed of 10% or above. When motor speed is less than 10%, 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.

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 motor torque (motor rated torque 100%).

Setting Motor Protection Operation Time

Setting Precautions
•
•
•
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 4 or 5 (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 variable torque IPM motor, the cooling ability will be lowered by operating under the base speed. Consequently, the frequency may cause motor overload protection (OL1) to occur, even below the rated current.
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.
Machine Protection
Limiting Motor Rotation Direction
If you set motor reverse rotation prohibited, a Reverse Run Command will not be accepted even if it is input.
Use this setting for applications in which reverse motor rotation can cause problems (e.g., fans, pumps, etc.)

Detecting Motor Overspeed
An error is detected when the number of motor rotations exceeds the regulated limit. An overspeed (OS) is detected when a speed that exceeds the set value in F1-08 continues for longer than the time set in F1-09. In flux vector control for PM, the Inverter will stop according to the setting in F1-03 after detecting an overspeed
(OS). In open-loop vector control for PM, Inverter output will be shut down (baseblock) after detecting an overspeed (OS) fault, and the motor will coast to a stop.

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.

Continuing Operation
Continuing Operation
This section explains functions for continuing or automatically restarting Inverter operation using speed search even if an error occurs.
Restarting Automatically After Power Is Restored
Even if a momentary power loss occurs, you can restart the Inverter automatically after power is restored to continue motor operation. To restart the Inverter after power has been restored, set L2-01 to the any of 1 to 4.
Make settings of L2-01 to L2-05 for related details of restarting.
• If L2-01 is set to 1:
After a momentary power loss, if the power is restored within the time set at L2-02, the inverter will restart. If not, alarm UV1 will occur.
If using an Inverter with a large capacity (200-V class of 37 kW or more and 400-V class of 75 kW or more), and L2-02 is set to 10 s or more, alarm UV3 (Inrush prevent circuit fault) will occur if the power is not restored within 10 s.
•
•
•
If L2-01 is set to 2:
After a momentary power loss, if the main power is restored while the supply voltage for the control board is maintained, the inverter will restart, and Alarm UV1 will not occur.
If L2-01 is set to 3:
After a momentary power loss, the Inverter will continue operating with Kinetic Energy Braking (KEB) until undervoltage conditions in the main circuit are detected. If the power is restored within the time set at
L2-02, the Inverter will restart. If not, alarm UV1 will occur.
If L2-01 is set to 4:
After a momentary power loss, the Inverter will continue operating with KEB until undervoltage conditions in the main circuit are detected.
If the main power is restored while the supply voltage for the control board is maintained, the Inverter will restart, and alarm UV1 will not occur.

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.
Continuing Operation
• If using elevating machines, disable momentary power loss detection (L2-01=0) to prevent the motor from coasting to a stop with the brake disengaged during a momentary power loss.
Speed Search
The speed search function finds the actual speed of the motor that is rotating on inertia, and then starts smoothly from that speed. When restoring power after a temporary power loss, the speed search function is useful to restart the fan that is rotating on inertia.

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 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 1.0 s. After waiting for the speed search wait time, the Inverter starts the speed search. If the delay time is less than 1.0 s, the speed search may not start properly. Make sure that the delay is set to 1.0 s or more.
During a high-speed rotation of 100 Hz or more, a speed search cannot be performed, and an overcurrent
(OC) or overvoltage (OV) fault may be detected.
If one of these faults is detected during a speed search after recovery from a momentary power loss, take the following measures.
•
•
•
Extend the search wait time (b3-05).
Enable the number of auto restart attempts (L5-01) for use together with a speed search.
Switch the speed search to momentary power loss detection (L2-01=3 or 4).

Continuing Operation During Momentary Power Loss
If L2-01 is set to 3 or 4, Kinetic Energy Braking (KEB) will be performed after a momentary power loss. With
KEB, the motor decelerates to a stop when a momentary power loss occurs and the Inverter continues to be controlled with the energy regenerated during deceleration. KEB control continues while the motor decelerates and the regeneration energy is reduced, until the DC voltage of the main circuit falls below the undervoltage detection level (L2-05).

The KEB operation levels are calculated by the following equations.

400 V class: KEB level = Set value (L2-05) + 100 (V)
Possible duration for continuous operation
• If L2-01 is set to 3, the Inverter will restart (reaccelerate) if the power supply of the main circuit is restored within the time assigned to L2-02 after a momentary power loss, as shown by Case A in the preceding figure. If using Inverters of 30 kW or less in the 200-V class or 55 kW or less in the 400-V class, the time assigned to L2-02 will start to be measured after the DC voltage of the main circuit falls

•
• below the undervoltage detection level set at L2-05. So, the possible duration for continuous operation can be longer than that for Inverters of other capacities, as shown by Case B in the preceding figure.
If L2-01 is set to 4, the Inverter will restart (reaccelerate) if the main power is restored while the power supply for the control board is maintained after a momentary power loss.
Shorten the KEB deceleration time at L2-06 if the inertia of the machine is low and an STO alarm or other similar alarm occurs after the power supply is restored.
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.
Kinetic Energy Braking (KEB) cannot be used to restart a motor driven by rotational inertia.
IMPORTANT
If using the 200-V class Inverter with a capacity of 37 kW to 75 kW or a 400-V class inverter with a capacity of
75 kW to 300 kW and set L2-01 to 2, 3, or 4, do not change the wiring of the control power-supply terminals
(200V class: r/
1
, 200/
2
200 , 400V class: r/
1
, 400/

1
and /
2
) are separated from the power supply lines (R/L1 and S/L2) and the control power is supplied from different lines, then do not set L2-01 to 2, 3, or 4. If these settings are used, the Inverter may be damaged.
Refer to the Main Circuit Configurations on page 2-13 and the Standard Connection Diagrams on page 2-14.
Continuing Operation at Constant Speed When Speed Reference Is Lost
The speed reference loss detection function continues operation using 80% speed of the speed reference before loss when the speed reference using an master speed analog input* is reduced 90% or more in 400 ms.
When the error signal during speed reference loss is output externally, set H2-01 to H2-03 (multi-function contact output terminal M1-M2, P1-PC, and P2-PC function selection) to C (speed reference lost).
* Speed references using the following master speed analog inputs are used to detect a frequency loss.
• Analog input using terminal A1
• Analog input using terminal A2 when H3-09 (Multi-function analog input terminal A2 function selection) is set to 0 (Add to terminal A1).
• Analog input using terminal A2 when H3-09 (Multi-function analog input terminal A2 function selection) is set to 2 (Auxiliary speed reference 1) and H3-13 (Terminal A1/A2 switching) is set to 1 (Use terminal A2 analog input as the master speed reference).

Continuing Operation
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 using the speed search function. 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 overheating)
• GF (Ground fault)
• PUF (Fuse blown)
• OV (Main circuit overvoltage)
• UV1 (Main Circuit Undervoltage, Main Circuit
Magnetic Contactor Operation Failure)
*
• PF (Main circuit voltage fault)
• LF (Output phase failure)
• RR (Braking transistor error)
• OL1 (Motor overload)
• OL2 (Inverter overload)
• OH1 (Cooling fan overheating)
• OL3 (Overtorque)
• OL4 (Overtorque)
* If L2-01 (Momentary power loss detection) is set to 0 (Disabled), the protection function will be activated, not the auto restart function.
Auto Restart External Outputs
To output auto restart signals externally, set H2-01 to H2-03 (multi-function contact output terminals M1-M2,
P1-PC, and P2-PC function selection) to 1E (auto restart).

* If L8-32 is set to 0, the motor will continue running even if a cooling fan fault occurred. However, the Inverter rated output current and the overload capacity will be reduced. The rated output current will be reduced to 80% if the normal rated output current is 100%, and the overload capacity will be reduced to the values as follows.
When CT is selected: 100% per every 3 minutes, 150% per every 30 seconds.
When VT is selected: 100% per every 37 seconds, 120% per every 13 seconds.
IMPORTANT
If L8-32 is set to 0, be sure to set H2-01 to H2-03 multi-function contact outputs to 10 (minor fault) or to 3D
(Inverter’s cooling fan fault.) If a cooling fan fault occurs, stop the Inverter immediately and replace the cooling fan. If the Inverter continues to run while a cooling fan fault occurs, the Inverter’s cooling ability will be affected and the Inverter’s internal temperature will increase and shorten the Inverter’s life.
During a cooling fan fault, the cooling fan stops for about 3 seconds every minute (interval operation.)

INFO
The most likely causes of RH (Mounted braking resistor overheating) being detected are that the deceleration time is too short or that the motor regeneration energy is too large. In these cases, lengthen the deceleration time or replace the Braking Resistor Unit with one with a higher breaking capacity.
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.

IMPORTANT
• If using baseblock commands with a variable load, do not frequently input baseblock commands during operation, as this may cause the motor to suddenly start coasting, and may result in the motor falling or slipping.
• If the baseblock command is cleared when the output frequency is high (100 Hz or more), OC, OV, or
STO alarm may occur. Clear the baseblock command when the output frequency is less than 100 Hz.
Input Terminal Functions
Stopping Acceleration and Deceleration (Acceleration/Deceleration
Ramp Hold)
The acceleration/deceleration ramp hold function stops acceleration and deceleration, stores the motor speed
(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 motor speed (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 motor speed (output frequency) is still stored even after the power supply is turned OFF.

When d4-01 is set to 1, the motor speed (output frequency) on hold is stored even after the power supply is turned OFF. If performing operations using this speed (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 motor speed (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 Speed References Using Contact Signals (UP/
DOWN)
The UP and DOWN commands raise and lower Inverter speed 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 motor speed (output frequency) depends on the acceleration and deceleration time. Be sure to set b1-02
(Run Command selection) to 1 (Control circuit terminal).

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.
Input Terminal Functions
Application Precautions
• Speed outputs using UP/DOWN commands are limited by the speed reference upper and lower limits set in constants d2-01 to d2-03. Here, speed references from analog speed reference terminal A1 becomes the speed reference lower limit. If using a combination of the speed reference from terminal A1 and the speed reference lower limit set in either constant d2-02 or d2-03, the larger lower limit will become the speed reference lower limit.
•
•
•
If inputting the Run Command when using UP/DOWN commands, the motor speed (output frequency) accelerates to the speed reference lower limit.
When using UP/DOWN commands, multi-step operations are disabled.
When d4-01 (Speed Reference Hold Function Selection) is set to 1, the speed 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 speed reference that has been stored. To reset (clear to 0) the stored speed reference, turn ON the UP or DOWN command while the Run Command is OFF.

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.

Adjustment target is the AM terminal when the H4-05 or H4-06 setting is displayed in quick, advanced, or verify mode while the motor is stopped.
To adjust the meter, multiply a value that is equivalent to 100% of the output by the gain setting and add the set bias.
* 2. The setting value will return to the factory setting if the control method is changed.
* 3. Adjustment target is the CH1 output when the F4-02 or F4-05 setting is displayed in quick, advanced, or verify mode while the motor is stopped.
Adjustment target is the CH2 output when the F4-04 or F4-06 setting is displayed in quick, advanced, or verify mode while the motor is stopped.
To adjust the meter, multiply a value equivalent to 100% of the output by the gain setting, and then add the set bias.
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 cards 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 card 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 card.
10 V/100% monitor output × output gain (F4-02) + output bias (F4-05)

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.
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.

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.
Register No.

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 via ENTER commands from the PLC during UV (main circuit undervoltage) alarm.
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.
Individual Functions
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 6.50 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.
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 Outputs the amount of operation proportional to the deviation. You cannot, however, set the deviation to zero using P control alone.
I control 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.
Individual Functions
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.

PID Adjustment Methods
Use the following procedure to adjust PID while performing PID control and measuring the response waveform.
1. Set b5-01 (PID Control Method Selection) to 1 or 2 (PID control enabled).
2. Increase b5-02 (Proportional Gain (P)) to within a range that does not vibrate.
3. Reduce b5-03 (Integral (I) time) to within a range that does not vibrate.
4. Increase b5-05 (Derivative (D) time) to within a range that does not vibrate.

In PID control, the b5-04 constant is used to prevent the calculated integral control value from exceeding a specified amount. If the load changes rapidly, the machine may be damaged or the motor may stall because of unpredictable response from the Inverter. In this case, reduce the set value.
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 speed 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 speed 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 Feedback Loss Detection
When performing PID control, be sure to use the PID feedback loss detection function. If PID feedback is lost, the Inverter speed reference may accelerate to the maximum speed.
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.

Inputting Torque References and Torque Reference Directions
The torque reference can be changed according to an analog input by setting H3-09 (Multi-function analog input terminal A2 selection) or H3-05 (Multi-function analog input terminal A3 selection) to 13 (torque reference) or 14 (torque compensation). The torque reference input methods are listed in the following table.

Speed Limiter (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.
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.
Individual Functions
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 sum of the speed limit and d5-05 (speed limit bias), 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 sum of the
6-
109
6
-110 speed limit and d5-05 (speed limit bias), a 0 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.

Torque Reference Adjustment
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 − 10 to 10 V signal level.
Individual Functions
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 speed 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.

Speed Control (ASR) Gain Adjustment
Use the following procedure to adjust C5-01 and C5-03 with the mechanical system and actual load connected.
At zero-speed, increase the setting of C5-01
(ASR P Gain 1) until no oscillation occurs.
At zero-speed, decrease the setting of C5-02
(ASR I Time 1) until no oscillation occurs.
Does oscillation develop when the motor operates at the maximum normal operating speed?
NO
Adjustment completed.
(When there is higher-level position control, adjust the position loop gain so that overshooting/undershooting doesn't occur.)
YES Decrease the setting of C5-01 (ASR P Gain 1).
Increase the setting of C5-02 (ASR I Time 1).
Fig 6.59 Adjustment for Flux Vector Control for PM
When the motor is rotating at minimum speed
(E1-09), increase the setting of C5-01 (ASR
P Gain 1) until no oscillation occurs.
When the motor is rotating at minimum speed
(E1-09), increase the setting of C5-02 (ASR I
Time 1) until no oscillation occurs.
Does oscillation develop when the motor operates at the maximum normal operating speed?
Any oscillation if motor started from a stopped state?
NO
Adjustment completed.
YES Decrease the setting of C5-01 (ASR P Gain 1).
Increase the setting of C5-02 (ASR I Time 1).
Fig 6.60 Adjustment for Open-loop Vector Control for PM
INFO
For oscillation, increasing the setting of C5-06 (ASR primary delay time) may be effective. By increasing the setting, the control responsiveness may slow down, so make adjustments until the control responsiveness is within the range necessary for the machines.

The multi-function analog outputs have the following functions with these constant settings.
• Multi-function analog output 1 (terminal FM): Outputs speed reference after a soft-start ( − 10 to 10 V).
• Multi-function analog output 2 (terminal AM): Outputs actual motor speed ( − 10 to 10 V).
Terminal AC is the multi-function analog output common.
We recommend monitoring both the speed reference after a soft-start and the motor speed to monitor the response delay or deviations from the reference value, as shown in the following diagram.
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.

Set the switching speed to about 80% of the motor operating speed or the speed at which oscillation occurs.
Low-speed Gain Adjustments (C5-03, C5-04)
Connect the actual load and adjust these constants at zero-speed operation in the flux vector control for PM or at minimum speed operation in the open-loop vector control for PM. 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 6-115 for details on making fine adjustments of high-speed operation.

(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 Speed Reference using the UP and DOWN Keys without Using the Enter
Key
Use this function when inputting speed references from the Digital Operator. When o2-05 is set to 1, you can increment and decrement the speed reference using the UP and DOWN Keys without using the Enter Key.
For example, enter the Run Command using a 0% reference, and then continuously press the UP Key to increment the speed reference by 0.01% only for the first 0.5 s, and then by 0.01% every 80 ms for 3 s thereafter.
Press and hold down the UP Key for 3 s minimum to reach the maximum speed 10 s after that. The speed 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).

Prohibiting Writing Constants from the Digital Operator
If you set A1-01 to 0, you can refer to and set the A1 and A2 constant groups, and refer to drive mode, using the Digital Operator.
If you set one of the constants H1-01 to H1-06 (multi-function contact input terminal S3 to S8 function selection) to 1B (write constants permitted), you can write constants from the digital operator when the terminal that has been set is ON. When the set terminal is OFF, writing constants other than the speed reference is prohibited. You can, however, reference constants.

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 speed reference set to 1% minimum, if the speed feedback from PG is greater than the time setting in F1-14, PGO is detected.
Detecting Z-phase Pulse Fall
If a Z-phase pulse is not detected during one full turn of the motor, the Z-phase pulse fault (DV1) alarm will be activated.
Detecting Z-phase Noise Fault
If a Z-phase pulse is detected with improper timing (the difference in the Z-phase between this rotation and the last rotation is outside the allowable range of discrepancy per single turn of the motor ± 5 degrees) in a succession exceeding the setting of F1-17, then the Z-phase noise fault (DV2) alarm will be activated.
Detecting Motor Inversion
• During Inverter operation, if the torque reference is positive and the acceleration speed is negative, or vice versa, and the difference between the speed reference and the motor speed is greater than 30% and this condition is detected in succession more times than the time multiplication of the setting of F1-18 by 5 ms
(F1-18 × 5 ms), then the motor inversion fault (DV3) alarm will be activated.

Application Precautions
•
•
The maximum 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.

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.
•

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 Inverter 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.)
OPE01 through OPE13 is displayed.
The set value for the constant is wrong. Refer to Operation Errors in this chapter and correct the setting.
CPF00 or CPF01 is displayed.
This is a Digital Operator communications error. The connection between the Digital Operator and the
Inverter may be faulty. Remove the Digital Operator and then re-install it.
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 and the DRIVE indicator on the Digital Operator (JVOP-161) does not light up, the Inverter 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 speed reference is too low.
If the speed reference is set below the speed set in E1-09 (Min. speed), the Inverter will not operate.
Raise the speed reference to at least the minimum speed.
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

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 speed reference is too low.
If the speed reference is set below the speed set in E1-09 (Min. speed), the Inverter will not operate. Raise the speed reference to at least the minimum output speed.
There is a multi-function analog input setting error.
If multi-function analog inputs H3-05 or H3-09 is set to 1 (speed gain), and if no voltage (current) is input, then the speed 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 motor responsiveness limit can 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 Inverter remains in the autotuning mode right after autotuning has been completed and cannot be operated even if the
Run Command is sent.
Press the MENU Key to display the drive mode on the Digital Operator and press the DATA/ENTER Key to enter the drive mode.
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.

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.
If the Motor Operates Higher Than the Reference
Use the following information if the motor operates higher than the reference.
The analog speed reference bias setting is wrong (the gain setting is wrong).
The speed reference bias set in constant H3-03 is added to the speed reference. Check to be sure that the set value is suitable.
A signal is being input to the speed reference terminal A2 or A3 .
When 0 (Add to terminal A1) is set for constant H3-09 (Multi-function Analog Input Terminal A2 Function the terminal A2 or A3 input voltage (current) is added to the speed reference. Check to be sure that the set value and analog input value are suitable.
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.
Troubleshooting
"Overvoltage inhibit selection enabled" is set.
When braking resistor is connected, set constant L3-11 (Overvoltage inhibit selection) to 0 (disabled). 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.
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 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.

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.
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 speed functions in constants d3-01 to d3-04 or install rubber padding on the motor base to reduce oscillation.
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 6-99.)
Troubleshooting
If Motor Speed Does Not Rise to Speed Reference
Use the following information if the motor speed does not rise to the speed reference.
The speed reference is within the jump speed range.
When the jump speed function is used, the motor speed does not change within the jump speed range. Check to be sure that the jump speed (constants d3-01 to d3-03) and jump speed width (constant d3-04) settings are suitable.
The speed reference upper limit has been reached.
The speed upper limit is determined by the following formula:
Maximum Speed (E1-04) × Speed Reference Upper Limit (d2-01) / 100
Check to be sure that the constant E1-04 and d2-01 settings are suitable.

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 75 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.

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.
Starting Torque
The overload current ratings of the Inverter and the type of motor being used restrict motor startup and acceleration characteristics depending on the amount of torque the load required. The load torque must be within the range that the Inverter can handle in combination with the IPM motor.
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.
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.
Inverter Application Precautions
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.
Motor Maximum Speed
The maximum speed of the motor is determined by the settings for the motor’s maximum speed (E1-04) and the number of motor poles (E5-04). If the settings are incorrect, the machine or the machine operator may be harmed. Check the motor nameplate to select the correct settings.
Deceleration Time
The motor's deceleration time is determined by the torque generated by the motor, the load torque, and the load's inertial moment (GD 2 /4). If the overvoltage inhibit selections are activated during deceleration, increase the deceleration time. The overvoltage inhibit selections will increase the deceleration time by the amount of time the overvoltage inhibit selection is active.
To reduce the deceleration time, increase the capacity of the motor and Inverter.
Handling
Observe the following precautions when wiring or performing maintenance for an Inverter.
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
Motor Application Precautions
This section provides precautions for motor application.
Applicable Motor
To the Varispeed F7S-Series Inverter, apply the dedicated IPM motor.
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 the rated speed.
