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 ex-
ceeded.
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 se-
lected? If the MDs and SGEs are o.k., check the machine for any dam-
age and rectify.
Clear the alarm with the RESET key. Restart the part program.
Axis %1 safe limit position exceeded
%1 = axis number
The axis has passed the limit position entered in MD
$MA_SAFE_POS_LIMT_PLUS or MD $MA_SAFE_POS_LIMIT_MINUS.
This axis is stopped with STOP C,D or E, according to the configura-
tion in MD $MA_SAFE_POS_STOP_MODE.
