Alarm disappears automatically when the test has been exited by deleting the "Test stop
of external shutdown" SGE.
Alarm display showing cause of alarm disappears. No further operator action
Axis %1 acceptance test mode is active
%1 = Axis number
Via the operator panel, an SI acceptance test has been started with the acceptance test
wizard. The acceptance test mode is activated via the NCK and drive for the time of this
acceptance test. In the acceptance test mode, SI PowerOn alarms can be acknowledged
with the Reset key.
- Alarm display.
Deselect the acceptance test with the acceptance test wizard or wait until completed
(acceptance test time can be parameterized via MD
$MA_SAFE_ACCEPTANCE_TEST_TIMEOUT).

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.
STOP of NC program processing. Stop of the axis with speed setpoint = 0 (STOP B). As
soon as the actual speed value is less than it is defined in MD
$MA_SAFE_STANDSTILL_VELO_TOL, but no later than after the expiration of the time
in MD $MA_SAFE_PULSE_DISABLE_DELAY.
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.
Check the tolerance of zero speed control: does the value match the precision and control
dynamics of the axis? If not, increase tolerance. If yes, check the machine for damage
and remove it.
Switch control OFF - ON.
