设定运行 Set operation




刹车设定 Brake setting

When the brake function is set at the factory, the BRK terminal and the DC- terminal are connected. When the motor is running, the operation and stop of the motor can be controlled by connecting or disconnecting the BRK terminal and the DC- terminal.

When BRK terminal and DC- terminal are connected, the motor runs; otherwise the motor stops running.



正反转设定 Forward and reverse setting

The factory setting of the forward / reverse switching function is F / R and DC- disconnection. When the power is turned on, the driver can drive the motor to run clockwise by adjusting the potentiometer.

Connect the switch or PLC with DC- to control its on-off, and then realize the motor's forward and reverse running switching.

When disconnecting the F / R and DC-end cables, the motor runs clockwise.

When connecting the F / R and DC-end cables, the motor runs counterclockwise.
