6 Alarms
6.2 Alarms from SIMODRIVE 611 digital
300951
Axis %1, drive %2 test stop running
Parameter %1 = NC axis number
%2 = drive number
Explanation The drive pulses are cancelled.
1.
2.
Interrogation: In the monitoring clock cycle.
The test stop has been activated by the user by setting the SGE "Test stop
selection". The drive pulses are cancelled.

Response Alarm display
Remedy The message disappears automatically if the user terminates the test by
withdrawing the SGE "Test stop selection". If a STOP A was initiated, then the
system can only be re-started using a power on.
Program continuation Alarm display disappears with alarm cause. No further operator action
necessary.
300952
Axis %1 drive %2 Acceptance test mode is active
Parameter %1 = axis number
%2 = drive number
Explanation The acceptance test mode has been activated by the user.
Response Alarm display
Remedy This message disappears automatically when the test is completed.
Program continuation Alarm display disappears with alarm cause. No further operator action
necessary.
301701
Axis %1 drive %2 Limit value for safe velocity too large
Parameter %1 = NC axis number
%2 = drive number
Explanation The run-up sequence is interrupted. The pulses remain cancelled.
Interrogation: In the monitoring clock cycle.
The limit value set for the safely-reduced speed is higher than the speed that
corresponds to a limit frequency of 200 kHz (300 kHz for 840D from SW 4.2).
The max. permissible speed that can be monitored is determined as follows:
nmax[rev/min] = (200000[Hz] * 60) / number of encoder pulses
Monitoring condition:
MD 1331: $MD_SAFE_VELO_LIMIT[n] <= (1 / ue) * nmax

If the positive acknowledgement that the pulses were cancelled is not
received within the time configured in MD 1357:
$MD_SAFE_PULSE_DIS_CHECK_TIME (time to check the pulse
cancellation), a STOP A is triggered.
If pulse cancellation is acknowledged within the configured time in the
drive, no stop response is triggered. When selected via the SGE "test stop
selection", the message remains until the selection has been withdrawn
(de-selected). The user activated the test stop by setting the SGE "test
stop selection". If the users withdraws this SGE, then the message is also
withdrawn.
If the positive acknowledgement that the pulses were cancelled is not
received within the time configured in MD 1357:
$MD_SAFE_PULSE_DIS_CHECK_TIME (time to check the pulse
cancellation), a STOP A is triggered.
If pulse cancellation is acknowledged within the configured time in the
drive, no stop response is triggered. When selected via the SGE "test stop
selection", the message remains until the selection has been withdrawn
(de-selected).
