Tolerances for
synchronism
The control reports that the synchronism of two spindles is reached if the
spindle remains within the control window of MP_syncTolerance for the
period of time defined in MP_timeSyncOK.
In MP_syncTolerance, define the size of the control window.
In MP_timeSyncOK, define the period of time which the spindle is to
remain within the control window.
