Wiring method of three-wire throttle on crane

The wiring method of the three-line throttle valve on the crane is as follows:

1. Connect the ground wires of the power line and the protection line with the corresponding wires on the controller.

2. It can be switched continuously. Don't twist too much every time. If the motor does not rotate smoothly, this state is wrong. If the knob is screwed too much, it will damage the controller.

3. In reverse rotation, under the condition that the phase sequence of the controller is known, exchange Hall lines A and C of the controller, and click on the lines A and B to exchange with each other, so that the forward rotation can be reversed.
