No. Name
Description
5
L1C, L2C (control
circuit power input
terminals)
See the nameplate for the rated voltage class.
6
L1, L2, L3 (main
circuit power input
terminals)
Used as the power input terminals for a three‑phase 220 V
servo drive. See the nameplate for the rated voltage class.
7
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.
sP⊕, NΘ (DC bus
terminals)
Used by the common DC bus for multiple servo drives.
8
U, V, W (terminals
for connecting the
servo motor)
Connected to U, V, and W phases of the servo motor.
9
Motor grounding
terminal
Connected to the grounding terminal of the motor for
grounding purpose.
10
Battery location Used to hold the battery box of the absolute encoder.
11
CN1 (control
terminal)
Used by reference input signals and other I/O signals.
12
CN2 (terminal for
connecting the
encoder)
Connected to the motor encoder terminal.
13
Servo drive
grounding terminals
Connected to the grounding terminal of the power supply
for grounding purpose.
Note
The main circuits of models S7R6 and S012 can be connected to a single‑phase or a three‑
phase power supply, depending on which one is available on site. No derating is required
when a single‑phase power supply is used for models S7R6 and S012. The 220 V power
supply can be connected between any two phases among L1, L2, and L3.
