Table 3–2 Description of main circuit terminal pins of servo drives in size B
No. Name
Description
1
L1, L2, L3
(power input
terminals)
See the nameplate for the rated voltage class.
Note: S5R5 (750 W) models support single‑phase 220 V
input only, with a 220 V power supply connected
between terminals L1 and L2.
2
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 B are
equipped with the built‑in regenerative resistor, with
terminals P⊕ and D jumpered by default.
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.
