Terminal Block Specifications
Installation
Terminal Name Function (signal level)
R/L1, S/L2, T/N/L3
Main circuit power supply input 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.)
