Jkh "the supervisor" is juct nickname

rollaway-up - I am sure that the elevator has a problem with bearings. Yes machine has resolver. We change bearings and installed in the shaft. The first we have a problem with running on the elevator. When we push button for run-down, the elevator has run-up. Wr clear all parameters and enters again. And when we "training" eleator he run down and next run up and stop.
We think that problem may be in resover, but wr do not sure.
