6 Alarms
6.2 Alarms from SIMODRIVE 611 digital
300906
Axis %1, drive %2 safe braking ramp exceeded
Parameter %1 = NC axis number
%2 = drive number
Explanation The drive is stopped using a STOP A.
Interrogation: In the monitoring clock cycle.
The actual speed of the axis has not decreased when braking with "n
(STOP B or STOP C), but has increased again above the speed limit corrected
by braking and the tolerance specified in MD 1348: $MD_SAFE_VELO_TOL
(actual speed tolerance for SBR).
The alarm can be re-configured in the MD
ALARM_REACTION_CHAN_NOREADY (channel not ready).
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
NC stop for alarm
Alarm display
Interface signals are set
Remedy Please inform the authorized personnel/service department. Check the braking
characteristics and, if necessary, modify the speed tolerance in MD 1348:
$MD_SAFE_VELO_TOL (actual speed tolerance for SBR). Restart is only
possible with power on.
Program continuation Power-down the control and power-up again.
300907
Axis %1, drive %2 Tolerance for safe operational stop exceeded
Parameter %1 = NC axis number
%2 = drive number
Explanation The drive is stopped using a STOP A or STOP B. This inhibits the pulses using
the relay "Antrieb_IMP" ["Drive_IMP"].
Interrogation: In the monitoring clock cycle.
The actual position has moved too far away from the setpoint/standstill position
(outside the standstill window). The standstill window is parameterized using
MD 1330: $MD_SAFE_STANDSTILL_TOL (standstill tolerance SBH)
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
NC stop for alarm
Alarm display
Interface signals are set
Remedy Please inform the authorized personnel/service department. Check the
tolerance for the safe operating stop: does the value match the precision and
control dynamic performance of the axis? If not, increase the tolerance.
Program continuation Power-down the control and power-up again.
300908
Axis %1, drive %2 STOP C initiated
Parameter %1 = NC axis number
%2 = drive number
Explanation The drive is stopped using a STOP C. At the end of the stop response, the
drive remains in closed-loop control, the axis is monitored for SBH.
Interrogation: In the monitoring clock cycle.
If a STOP C was initiated, then this can have several reasons (depending on
what has been configured):

SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
The safely-reduced speed monitoring has responded (MD 1361:
$MD_SAFE_VELO_STOP_MODE (stop response, safely-reduced speed )
or MD 1363: $MD_SAFE_VELO_STOP_REACTION (SG-specific stop
response) (840D from SW4.2)).
