January 2012 6.3 Configuration of Axes 639
Comparison of the acceleration behavior:
MP_advancedSettings, bit 2 = 1:
Only effective for a spindle in position feedback control. If bit 2 = 1, the
control does not use the modulo counting mode to calculate the following
error (servo lag) that results from acceleration or braking. If a spindle motor
tends to vibrate, the control response of the spindle can thus be improved
in certain cases. Vibrations are suppressed, but the axis is "lagging" because
the following error that has built up is corrected in any case. The nominal
speed is reached with some delay because of the reduction of the following
error.
