Description
1
L1, L2
(power input
terminals)
See the nameplate for the rated voltage class.
2
P⊕, NΘ
(DC bus terminals)

P⊕ and C
(terminals for
connecting
external
regenerative
resistor)
If an external regenerative resistor is needed, connect it
between terminals P⊕ and C.
3
U, V, W
(terminals for
connecting the
servo motor)
Connected to U, V, and W phases of the servo motor.
4
Motor grounding
terminal
Connected to the grounding terminal of the motor for
grounding purpose.
