1. After purchasing this controller personally, it comes with a power cord inside. One end is connected to the controller, and the other end is connected to the motor. Then, plug in the power cord and it can be used normally
. (The plug connected to the motor has 4 wires, corresponding to black (live wire), blue (zero wire), brown (live wire), and yellow (ground wire). If it is different from the jack of the outgoing wire on the motor, you can connect the wires of the corresponding color yourself. The colors must match, otherwise there will be a short circuit!)
2. Controller principle: The tubular motor controller outputs 2 strands of 220V voltage, directly controlling the forward and reverse rotation of the motor.
The motor needs to be an AC motor to be able to adjust the limit of the tubular motor: there is a dedicated hexagonal plastic wrench to adjust it on the motor, which is not related to the receiver.
