Check the tolerance for the standstill monitoring: does the value match
the precision and control dynamic performance of the axis?
If not, increase the tolerance. If yes, check the machine for damage
and repair it.
Switch--off – switch--on the control
Axis %1 safely reduced speed exceeded
%1 = axis name, spindle number
The axis has moved too quickly and faster than that specified in
MD36931 $MA_SAFE_VELO_LIMIT.
If function "Correction safely reduced speed" in MD36901
$MA_SAFE_FUNCTION_ENABLE is enabled, then for SG2 and SG4,
the active correction value from MD36932
$MA_SAFE_VELO_OVR_FACTOR[0...15] must be taken into account
for the permissible speed.
Special case:
When SBH/SG is active in a configuration with a 1--encoder system,
the speed that corresponds to the encoder limit frequency was
exceeded.

NC stop for alarm
The axis is stopped with STOP A, C, D or E, depending on what has
been configured in MD36961 $MA_SAFE_VELO_STOP_MODE or
MD36963 $MA_SAFE_VELO_STOP_REACTION.
If no obvious operator error has occurred: Check the input value of the
MD, check safe input signals: is the correct safely reduced speed
selected?
Clear the alarm with the RESET key. Restart the part program.
Axis %1 safe limit position exceeded
%1 = axis name, spindle number
The axis has passed the limit position entered in MD36934
