IMPORTANT
1. Control circuit terminals are arranged as shown below.
2. The output current capacity of the +V and -V terminal is 20 mA.
3. Disable the stall prevention during deceleration (set parameter L3-04 to 0) when using a Braking Resistor
Unit. If this parameter is not changed to disable stall prevention, the system may not stop during decelera-
tion.
4. Main circuit terminals are indicated with double circles and control circuit terminals are indicated with single
circles.
5. Sequence input signals S1 to S7 are shown in Table
2.23
Sinking/Sourcing

and

Signals for
sourcing mode connections (+24 V common) for PNP transistor sequence and contacts for European use.
Check your system and select sinking mode or sourcing mode. Refer to Table

Signals.
6. 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.
See Chapter 6 for the bi-directional voltage input for terminal A1.
7. The multi-function analog output is a dedicated meter output for an analog frequency meter, ammeter, volt-
meter, wattmeter, etc. Do not use this output for feedback control or for any other control purpose.
8. DC reactors to improve the input power factor built into 200-V class Inverters for 22 to 110 kW and 400-V
class Inverters for 22 to 160 kW. A DC reactor is thus an option only for Inverters for 18.5 kW or less.
Remove the short bar when connecting a DC reactor to Inverters for 18.5 kW or less.
9. Set parameter L8-01 to 1 when using a Braking Resistor (3G3IV-PERF). When using a Braking Resistor
Unit, a shutoff sequence for the power supply must be made using a thermal relay trip.
