Main circuit
Control Circuit
Terminal Name Function (signal level)
R/L1, S/L2, T/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 S/L2
(T/L3 is not connected to anything)
U/T1, V/T2, W/T3
Inverter output Used to connect the motor
B1, B2
Braking resistor connection Available for connecting a braking resistor or the braking resistor unit option.
+2, +1
DC reactor connection Remove the short bar between +2 and +1 when connecting DC reactor (option)
+1, –
DC power supply input For power supply input (+1: positive electrode; – : negative electrode)*
Grounding For grounding (grounding should conform to the local grounding code.)
