Function (signal level)
Used to connect line power to the drive.
Used to connect the motor
Normally connected by the short-circuit bar. Remove the short-circuit bar between +1 and P/
+2 when a DC reactor is connected.
Connect option braking resistor (if a braking torque is required)
Connect optional regenerative braking units.
For grounding (grounding should conform to the local grounding code.)
