1. Tripping motor line

2. Check whether the limit switch is loose

The motor line is inserted reversely, but the new machine generally does not have this problem, because the machine has been tested before delivery. However, if you have changed the motor or line later, this problem may occur. If this problem occurs, you can adjust the motor line, the two sides and the middle.

The limit switch line is loose. When the limit switch line is loose or the limit switch is broken, the machine will rotate in the opposite direction when it returns to the original point. However, the motor can only move a small distance, and it can only move in the opposite direction for about one centimeter at a time. If this problem occurs, it may be that the limit switch line is loose or the limit switch is broken, This is a good limit switch can be adjusted to detect whether the limit problem, if so, then replace a limit switch.
