Tightening torque
Connect the input power supply.
Connect to 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 optional regenerative braking
units.
(If a braking torque is required)
Ground (Connect to ground to prevent
electric shock and reduce noise.)
's terminal symbols, R/L1 corresponds to L1, S/L2 to L2, and T/L3 to N/L3.
