The polarity of the analog tacho respectively pulse encoder [depending on M1SpeedFbSell (50.03)] is checked against the EMF.
Check:
- EMF FbMonLev (30.15), SpeedFbMonLev (30.14)
- polarity of tacho cable
- polarity of pulse encoder cable (e.g. swap channels A and A not)
- polarity of armature and field cables
- direction of motor rotation
