Description
6
CHARGE (bus
voltage indicator)
Used to indicate the electric charge is present in the bus
capacitor. When this indicator lights up, it indicates the
electric charge may be still present in the internal capacitor
of the servo drive even though the main circuit power
supply is switched off.
To prevent electric shock, do not touch the power supply
terminals when this indicator lights up.
7
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.
8
P⊕, NΘ (DC bus
terminals)
Used by the common DC bus for multiple servo drives.
P⊕, D, C (terminals
for connecting
external
regenerative
resistor)
Remove the jumper bar between terminals P⊕ and D before
connecting an external regenerative resistor between
terminals P⊕ and C.
9
U, V, W (terminals
for connecting the
servo motor)
Connected to U, V, and W phases of the servo motor.
10
Motor grounding
terminal
Connected to the grounding terminal of the motor for
grounding purpose.
11
Battery location Used to hold the battery box of the absolute encoder.
12
Servo drive
grounding terminal
Connected to the grounding terminal of the power supply
for grounding purpose.
