Program Continuation:

Axis %1 tolerance for safe standstill exceeded

%1 = Axis number

The axis has moved too far away from the setpoint position. It is further away than allowed in MD SAFE_STANDSTILL_TOL.

The alarm can be reprogrammed in the MD

$MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).

-    Mode group not ready.

-    Channel not ready.

-    NC Start disable in this channel.

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

-    Channel not ready.

Stop of the axis with the setpoint speed value=0 (STOP B). As soon as the actual speed value is smaller than defined in MD $MA_SAFE_STANDSTILL_VELO_TOL, but the latest after time-out in MD $MA_SAFE_PULSE_DISABLE_DELAY, the pulses will be suppressed (STOP A).

Check the tolerance of zero speed monitoring: does the value match the precision and control dynamics of the axis? If not, increase tolerance. If yes, check the machine for any damage and rectify it.

Switch control OFF - ON.
