No. Name
Description
④
CN3, CN4 (Profinet
communication
terminal)
CN4(P1) is connected to the host controller, and CN3(P2)
is connected to a slave.
⑤
CN1 (control
terminal)
Used by reference input signals and other I/O signals.
⑥
CN2 (terminal for
connecting the
encoder)
Connected to the motor encoder terminal.
⑦
CHARGE (bus
voltage indicator)
Indicates the electric charge is present in the bus
capacitor. When the indicator turns on, charges possibly
still exist in the internal capacitor of the servo unit, even
if the power supply of the main circuit is OFF. To prevent
electric shock, do not touch the power terminals when
this indicator lights up.
⑧
L1, L2, L3 (power
input terminals)
See the nameplate for the rated voltage class.
Note: S5R5 (0.75 kW) models support single‑phase 220 V
input only, with a 220 V power supply connected
between terminals L1 and L2.
⑨
P⊕, N⊖ (servo 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.
⑩
U, V, W (terminals
for connecting the
servo motor)
Connected to U, V, and W phases of the servo motor.
⑪
Motor grounding
terminal
Connected to the grounding terminal of the motor for
grounding purpose.
⑫
Battery location Used to hold the battery box of the absolute encoder.
⑬
Power supply
grounding terminal
Connected to the grounding terminal of the power supply
for grounding purpose.
