1. Control circuit terminals are arranged as shown below.

2. The output current capacity of the +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 user parameter 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 Card) is not required for open-loop vector control.
7. Sequence input signals S1 to S12 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 exter-
nal power supply, refer toTable 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, volt-
meter, 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 built into 200-240 V Class Drives for 18.5 to 110 kW and
380-480 V Class Drives for 18.5 to 300 kW. A DC reactor is thus an option only for Drives for 15 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.
