regards,


I have lathe ML26. centurion 6, when I execute a command s500 m3, for example. the control displays an S560 CW speed. I try to move the potentiometer to zero%, but the spindle does not reach zero. and the control shows S129.
program any speed provided the minimum rpm in control is S129. the spindle really is seen turning at less than 129 rpm. but it does not reach zero.
try to change the PPR parameter of the spindle encoder that is in 4000, change it to 8000. and according to the control it now shows instead of 129 shows 85.
What could be generating this error?

thanks,
