Hi,


Pulse wheel works ok to - direction, but when rotating to + direction movement is not smooth, machine stops suddenly and then starts to move again.
Position is ok but movement is not smooth.
There is 4 wire's coming back to pulse wheel, they seem to be ok when shaking.
Wire's are marked A,B,0V, +V
What could be reason....new pulse wheel or some card problem ?


Thanks,

GB
