A: No.39 fault means abnormal height of elevator (serious slipping of wire rope). The elevator is not located on the ground floor and the top floor, but the height data has been below or exceeded the limit value.
1. The guide shoe at the car side or counterweight side is too tight;
2. It is suggested that the acceleration and deceleration parameters should be set a little lower to try the operation again, or the parameter P0.02 (maximum speed of the elevator) can also be set a little lower;
3. It can set F0.21 (leveling operation scheme) = 100, save parameters, and power on the all-in-one machine. Enable the scheme of end crawl leveling.
