I have a 5 stop kmc831. That will run for a day, week, or month until it generates these faults, and I find it in the overhead. No one is ever occupied, car is always empty. 130 fault occurs 1st however I have a Kone drive so this fault is not used ( according to manual). 108 is position encoder, motor encoder, load weighed, motor wiring, brake stuck….exc. the car slows at terminal floor. Then seems to start again into overhead. I have only seen it happen once. Went through the brakes, checked encoder wheels, etc… any help is appreciated.
