IMPORTANT
1. Control circuit terminals are arranged as shown below.
Inverters with SPEC: C or earlier
Inverters with SPEC: E or later
2. The output current capacity of the +V 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 stall prevention during deceleration (set constant L3-04 to 0) when using a Braking Resistor
Unit. If this user constant is not changed to disable stall prevention, the system may not stop during deceleration.
4. Main circuit terminals are indicated with double circles and control circuit terminals are indicated with single circles.
5. The wiring for a motor with a cooling fan is not required for self-cooling motors.
6. PG circuit wiring (i.e., wiring to the PG-B2 Board) is not required for control without a PG.
7. Sequence input signals S1 to S8 are labeled for sequence connections (0 V common and sinking mode) for no-voltage contacts or NPN transistors. These are the default settings.
For PNP transistor sequence connections (+24V common and sourcing mode) or to provide a 24-V external power supply, refer to Table 2.13
.
8. The master speed frequency reference can set to input either a voltage (terminal A1) or current (terminal
A2) by changing the setting of parameter H3-13. The default setting is for a voltage reference input.
9. The multi-function analog output is a dedicated meter output for an analog frequency meter, ammeter, voltmeter, wattmeter, etc. Do not use this output for feedback control or for any other control purpose.
10.DC reactors to improve the input power factor are built into 200 V Class Inverters for 22 to 110 kW and 400
V Class Inverters for 22 to 300 kW. A DC reactor is thus an option only for Inverters for 18.5 kW or less.
11.Set parameter L8-01 to 1 when using a breaking resistor (ERF). When using a Braking Resistor Unit, a shutoff sequence for the power supply must be made using a thermal relay trip.
12.The permissible load of a multi-function contact output and an error contact output is 10 mA. Use a multifunction open-collector output for a load less than 10 mA.
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.
14.If turning off the power only for the main circuit but leaving the power ON for the control circuit, use a separate power supply for the control circuit and a specially designed Inverter, which are sold as options.

IMPORTANT
1. Determine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage. Line voltage drop is calculated as follows:
Line voltage drop (V) = 3 x wire resistance (W/km) x wire length (m) x current (A) x 10 -3
2. Use a closed-loop connector (made by J.S.T. Mfg. Co., Ltd. or an equivalent) for the main circuit input and output terminals of Inverters of 200V 11 kW or more and those of 400V 22 kW or more.

Wiring 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
150% of the rated output current).
If the same MCCB is to be used for more than one Inverter, or other devices, set up a sequence so that the power supply will be turned OFF by a fault output, as shown in Fig 2.6
.

Fault output
(NC)
* For 400 V Class Inverters, connect a 400/200 V transformer.
Fig 2.6 MCCB Installation
Installing a Ground Fault Interrupter
Inverter outputs use high-speed switching, so high-frequency leakage current is generated. 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.
• Correct Noise Filter Installation

Wiring the Output Side of Main Circuit
Observe the following precautions when wiring the main output circuits.
Connecting the Inverter and Motor
Connect output terminals U, V, and W to motor lead wires U, V, and W, respectively.
Check that the motor rotates forward with the Forward Run Command. Switch over any two of the output terminals to each other and reconnect if the motor rotates in reverse with the Forward Run Command.
Never Connect a Power Supply to Output Terminals
Never connect a power supply to output terminals U, V, and W. If voltage is applied to the output terminals, the internal circuits of the Inverter will be damaged.
Never Short or Ground Output Terminals
If the output terminals are touched with bare hands or the output wires come into contact with the Inverter casing, an electric shock or grounding will occur. This is extremely hazardous. Do not short the output wires.
Do Not Use a Phase Advancing Capacitor or Noise Filter
Never connect a phase advancing capacitor or LC/RC noise filter to an output circuit. The high-frequency components of the Inverter output may result in overheating or damage to these part or may result in damage to the Inverter or cause other parts to burn.
Precautions When Using an Magnetic Contactor
Never connect an magnetic contactor between the Inverter and motor and turn it ON or OFF during operation.
If the magnetic contactor is turned ON while the Inverter is operating, a large inrush current will be created and the overcurrent protection in the Inverter will operate.
2-
17

-18
When using an magnetic contactor to switch to a commercial power supply, stop the Inverter and motor before operating the magnetic contactor. Use the speed search function if the magnetic contactor is operated during operation. If measures for momentary power interrupts are required, use a delayed release magnetic contactor.
Installing a Thermal Overload Relay
This Inverter has an electronic thermal protection function to protect the motor from overheating. If, however, more than one motor is operated with one Inverter or a multi-polar motor is used, always install a thermal relay (THR) between the Inverter and the motor and set L1-01 to 0 (no motor protection). The sequence should be designed so that the contacts of the thermal overload relay turn OFF the magnetic contactor on the main circuit inputs.
Installing a Noise Filter on Output Side
Connect a noise filter to the output side of the Inverter to reduce radio noise and inductive noise.

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

Countermeasures Against Radio Interference
Radio noise is generated from the Inverter as well as from the input and output lines. To reduce radio noise, install noise filters on both input and output sides, and also install the Inverter in a totally enclosed steel box.
The cable between the Inverter and the motor should be as short as possible.

Cable Length between Inverter and Motor
If the cable between the Inverter and the motor is long, the high-frequency leakage current will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust the carrier frequency (set in C6-01, C6-02) as shown in Table 2.6
. (For details, refer to Chapter 5 User Constants .)

Ground Wiring
Observe the following precautions when wiring the ground line.
•
•
Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100 Ω and that of the 400 V Inverter with a ground resistance of less than 10 Ω .
Do not share the ground wire with other devices, such as welding machines or power tools.
•
•
Always minimize the length of the ground wire.
Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.
When using more than one Inverter, be careful not to loop the ground wire.

0 (Disables stall prevention function)
3 (Enables stall prevention function with braking resistor)
L8-01 is used when a braking resistor without thermal overload relay trip contacts (ERF type mounted to
Inverter) is connected.
The Braking Resistor Unit cannot be used and the deceleration time cannot be shortened by the Inverter if L3-
04 is set to 1 (i.e., if stall prevention is enabled for deceleration).
Wiring Main Circuit Terminals
To prevent the Unit from overheating, design the sequence to turn OFF the power supply for the thermal overload relay trip contacts of the Unit as shown in Fig 2.14
.

Wire Sizes and Closed-loop Connectors
For remote operation using analog signals, keep the control line length between the Digital Operator or operation signals and the Inverter to 50 m or less, and separate the lines from high-power lines (main circuits or relay sequence circuits) to reduce induction from peripheral devices.
When setting frequencies from an external frequency setter (and not from a Digital Operator), use shielded twisted-pair wires and ground the shield to terminal E (G), as shown in the following diagram.

Installing and Wiring Option Boards
Installation
Before mounting an option board, remove the terminal cover and be sure that the charge indicator inside the
Inverter is not lit. After confirming that the charge indicator is not lit, remove the Digital Operator and front cover and then mount the option board.
The side of the front cover of the Inverter for 200/400 V Class 0.4 to 5.5 kW can be cut out as described in Fig
2.25
to make wiring of the option board easy. If the side of the front cover is cut out, the protective structure will be open chassis (IEC IP00).
Refer to documentation provided with the option board for actual mounting instructions for option slots A, C, and D.
Preventing C and D option board Connectors from Rising
After installing an option board into slot C or D, insert an option clip to prevent the side with the connector from rising. The option clip can be easily removed by holding onto the protruding portion of the clip and pulling it out.
Remove the option clip before installing an option board into slot C or D. The option board cannot be installed completely and may not function property if it is installed with the option clip attached.

Wiring Terminal Blocks
Use no more than 100 meters of wiring for PG (encoder) signal lines, and keep them separate from power lines.
Use shielded, twisted-pair wires for pulse inputs and pulse output monitor wires, and connect the shield to the shield connection terminal.
Wire Sizes (Same for All Models)
Terminal wire sizes are shown in Table 2.19

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.

Selecting the Number of PG (Encoder) Pulses
The setting for the number of PG pulses depends on the model of PG Speed Control Board being used. Set the correct number for your model.
PG-A2/PG-B2
The maximum response frequency is 32,767 Hz.
Use a PG that outputs a maximum frequency of approximately 20 kHz for the rotational speed of the motor.
