The pulses are deleted.
1. If the positive acknowledgement is not received within the time configured in MD 1357:
$MD_SAFE_PULSE_DIS_CHECK_TIME (time for checking the pulse deletion), STOP A
is triggered.
2. If pulse deletion is acknowledged within the configured time in the drive, no stop reac-
tion is triggered. This message will be displayed during selection via the SGE "Test stop
selection" until the selection is canceled.
Request: In monitoring cycle.
The test stop has been activated by the user by setting the SGE "Test stop selection". The
pulses are deleted.

- Alarm display.
The message disappears automatically if the test is terminated by the user by clearing the
SGE "Test stop selection". If STOP A is triggered, restart is only possible with POWER
ON.
Alarm display showing cause of alarm disappears. No further operator action
Axis %1 drive %2 acceptance test mode is active
%1 = Axis number
%2 = Drive number
The acceptance test mode has been activated by the user.
- Alarm display.
This message disappears automatically when the test is finished.
Alarm display showing cause of alarm disappears. No further operator action
Axis %1 drive %2 limit value for safe velocity too large
%1 = Axis number
%2 = Drive number
Booting has been interrupted. The pulses remain disabled.
Request: In monitoring cycle.
The limit value of the safe velocity exceeds the velocity corresponding to a limit frequency
of 200 kHz (300 kHz for 840D with SW4.2 and higher and for 840C with SW6.1 and
higher).
The max. permissible speed that can be monitored is determined as follows:
nmax[rev/min] = (200000[Hz] * 60) / encoder marks value
Monitoring condition:
Modify MD 1331: $MD_SAFE_VELO_LIMIT[n] <= (1 / ue) * nmax
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department. Check the entry in the
machine data MD 1331: $MD_SAFE_VELO_LIMIT[n] (safe velocity limit values) correct, if
necessary, and perform POWER ON.
Switch control OFF - ON.
