Axis Monitoring (A3)
2.2 Motion monitoring functions
Effect
If the axis is pushed out of position beyond the clamping tolerance during clamping the
following occurs:
● Alarm 26000 "Clamping monitoring" is triggered
● The affected axis/spindle is brought to a standstill with rapid stop (with open position
● If the axis/spindle is assigned to an interpolatory grouping with other axes/spindles, then

Speed setpoint monitoring

Function
Speed setpoint monitoring checks whether the setpoint specification does not exceed the
maximum permissible drive speed in MD 36210 MD36210 CTRLOUT_LIMIT (maximum
speed setpoint). If required, the speed is limited to this value and the axis/spindle stopped
and an alarm output.
The maximum speed for the axes (in percent) exceeds the speed at which the velocity in
MD3200 MAX_AX_VELO is reached (100%). This also determines the control margin.
On an analog spindle the maximum speed that can be output must not exceed the speed
reached at the maximum setpoint output voltage of 10 V (100%).
The speed setpoint consists of the speed setpoint of the position controller and the
feedforward control parameter (if feedforward control is active).

Speed setpoint monitoring is always active for axes and spindles.

MD36610 AX_EMERGENCY_STOP_TIME (duration of the braking ramp for error states).
these are also braked by rapid stop with following error reduction (default for partial
position setpoint = 0).
