PE Green
Regenerative resistor
terminals
P, D, C, N
Use an
external
resistor
Connect P and C to the
resistor, and P and D are left
open.
Use a built-in
resistor
Short-circuit P and D contacts,
and P and C are left open.
Ground terminals
Connect to the ground wires for the power and
servo motor, which is in the green screw on the
outside of the controller.
P: main circuit [+]
terminal
N: main circuit [-]
terminal
P, N
If brake unit is used, you should connect its [+]
terminal to the [P] terminal of servo drive, and
connect its [-] to the [N] terminal of servo drive.
The brake unit is optional purchase item, usually it
is not required. It is used to absorb the regenerative
energy when the huge regenerative power
generated by the servo motor.
I/O connector CN1 Connect to the host controller.
Encoder connector CN2 Connect to the encoder.
