Control loop power, input according to specifications

By default, short wires are connected between P⊕-D.

When the braking force is insufficient, please make an open

circuit between P⊕-D.

(remove the short wiring) and connect external braking resistor

between P⊕-C

External braking resistors should be purchased separately.

Servo DC bus terminal for common bus connection when

multiple units are connected in parallel

The servo motor connection terminal, connected to the U, V, W

of the motor.

Two grounding terminals are connected to the power grounding

terminal and the motor grounding terminal.

Be sure to ground the entire system.
