• Speed or torque feedforward control is activated. In this case, a higher servo gain factor is set than displayed
with MD32200:
• Filter for jerk limitation or dynamic response adaptation is activated. In this case, a lower servo gain factor is
set than displayed with MD32200.
Diagnostics for alarms
This information of the service display "Axis/spindle" is also used as diagnostics help when alarms occur, e.g.:
• "Zero speed monitoring"
⇒ Following error > MD36030 $MA_STANDSTILL_POS_TOL (standstill tolerance)
• "Contour monitoring"
⇒ Contour deviation > MD36400 $MA_CONTOUR_TOL (contour monitoring tolerance range)
• "Speed setpoint limitation"
⇒ Speed setpoint > MD36210 $MA_CTRLOUT_LIMIT (maximum speed setpoint)
• "Position monitoring"
⇒ Following error > MD36010 $MA_STOP_LIMIT_FINE (exact stop fine)
• "Measuring system cannot be switched over"
⇒ Difference between Position actual value measuring system 1 and 2 > MD36500
$MA_ENC_CHANGE_TOL (max. tolerance for position actual value sensing)
• "Clamping monitoring"
⇒ Following error > MD36050 $MA_CLAMP_POS_TOL (clamping tolerance with interface signal "Clamping
active")
The behavior of the NC control in response to individual alarms, and remedial action is described in:
