Main-circuit power supply
terminals
These are the input terminals for the main-circuit power supply.
DC reactor terminals
Normally short-circuit b1 and +2.
If harmonic control measures are required, connect a DC reactor b1 and +2.
Main-circuit DC output
Do not connect anything to this terminal.
L1C
Control circuit power
supply terminals
These are the input terminals for the control power supply.
L2C
B1 and B2 or
B1, B2, and B3
External regeneration
resistance terminals
Connect an external regeneration resistor to these terminals if the regenerative capacity of the internal capacitor is
exceeded. (An external regeneration resistor cannot be connected to the 30 to 200 W models.)
U
Servo motor
