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.
4
U, V, W
(terminals for
connecting the
servo motor)
Connected to U, V, and W phases of the servo motor.
5
Motor grounding
terminal
Connected to the grounding terminal of the motor for
grounding purpose.
Servo drives in size E (rated power: 5.0 kW to 7.5 kW): SV660PT017I, SV660PT021I,
and SV660PT026I
