Fault F0022 when slowing down motor

Roussey Posts: 37 Rating: (0)	I have a motor working in 2 directions and everytime it is slowing down regardless of the direction of rotation, the failure F0022 occurs. Do somebody have an idea of waht is happening? I think it is not overload nor earth fault because we have already measured resistence to earth.

In my case the problem was inside drive I interchanged the drive with similar drive at another location the problem also interchanged. some dry soldering was found around DC charging relay inside the drive.

But, dont forget to work on placing dynamic resistor as mentioned for this fault. Good luck, Vishal Parmar. --------------------- Everyday is a new page inbook of life.
