If you have re roped have you recalibrated the loadweigher? As closed loop if this is out of calibration it will give you running issues ie roll back etc.
Presuming it is a LCE controller (monospace etc)
Put lift car in middle of shaft and check menu 5, submenu 1 - this will display a number L******, the number displayed being % of load in lift car. With lift at mid point in shaft, empty car, it should be close to 0 (+/- 2% should be ok). If this is out then you need to re-calibrate the load weigher.
