Description
1
L1C, L2C
(control circuit
power input
terminals)
See the nameplate for the rated voltage class.
2
L1, L2, L3
(main circuit power
input terminals)
See the nameplate for the rated voltage class.
3
P⊕, NΘ
(DC bus terminals)
Used by the common DC bus for multiple servo drives.
P⊕, D, C
(terminals for
connecting
external
regenerative
resistor)
If an external regenerative resistor is needed, connect it
between terminals P⊕ and C. Servo drives in size C and
size D are equipped with the built‑in regenerative
resistor, with terminals P⊕ and D jumpered by default.
