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.
Power-down the control and power-up again
Axis %1 safely-reduced speed exceeded
%1 = axis number
The axis has moved too quickly and faster than that specified in MD
$MA_SAFE_VELO_LIMIT.
When SBH/SG is active in a configuration with a 1-encoder system, the
speed that corresponds to the encoder limit frequency was exceeded.
The axis is stopped with STOP A, C, D or E, depending on what has
been configured in MD $MA_SAFE_VELO_STOP_MODE or MD
$MA_SAFE_VELO_STOP_REACTION.

If no obvious operator error has occurred: Check the value entered into
the MDs, check the SGEs: Was the correct safely-reduced speed
selected? If the MDs and SGEs are o.k., check the machine for any
damage and rectify.
Clear the alarm with the RESET key. Restart the part program.
