Ter m i nal nam e Purpose Details
R/L1, S/L2, T/N/L3 Main circuit power supply unit
Used to connect line power to the drive
Drives with single-phase 200 V input power use only terminals R/L1 and N (T/L3), terminal S/L2 is not
available for these units
U/T1, V/T2, W/T3 Inverter output Used to connect the motor
PD/+1, P/+ External DC reactor terminal
Normally connected by the short-circuit bar. Remove the short-circuit bar between +1 and P/+2 when a
DC reactor is connected
P/+, N/-
Regenerative braking unit connection
terminal
Connect optional regenerative braking units (if a braking torque is required)
Grounding For grounding (grounding should conform to the local grounding code)
