27024
Axis %1: STOP A activated
Parameter %1 = axis number
Explanation This alarm is output as a result of
- Alarm 27011 "safely-reduced speed exceeded" (for the appropriate
configuring in $MA_SAFE_VELO_STOP_MODE,
$MA_SAFE_VELO_STOP_REACTION),
- Alarm 27013 "safe braking ramp exceeded",
- Alarm 27023 "Stop B initiated"
- unsuccessful test stop.
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
Interface signals are set
Alarm display
NC stop for alarm
"Pulse cancellation" initiated.
Remedy Remove the causes of
- Alarm "safely-reduced speed exceeded",
- Alarm "safe braking ramp exceeded",
- Alarm "Stop B initiated"
- Unsuccessful test stop
(refer to the description of the alarms).
Program continuation Power-down the control and power-up again.
27030 Axis %1 function not supported on this 611D module
Parameter %1 = axis number
Explanation SINUMERIK Safety Integrated can only be used with the 611D Performance
control modules with 2 measuring circuits per drive and shutdown relay. An
attempt has been made to activate a safety function although no such module
is plugged in.
Response Mode group not ready
Channel not ready
NC start inhibit in this channel

NC stop for alarm
Remedy Replace the module or switch-off safety functions in MD
$MA_SAFE_FUNCTION_ENABLE.
Program continuation Power-down the control and power-up again.
27031
Axis %1 limit value for safely-reduced speed %2 for ratio %3 too
high (max. %4)
Parameter %1 = axis number
%2 = limit value index
%3 = number of the ratio
%4 = maximum speed
Explanation All of the limit values in MD $MA_SAFE_VELO_LIMIT must be set so that the
limit frequency of the amplitude monitoring in the measuring circuit hardware is
not exceeded. The limit value that does not maintain this condition, is specified
here as second parameter (1 for SG1, 2 for SG2, etc.). The third parameter
indicates the gear stage, e.g. 1 for gear stage 1, 2 for gear stage 2, etc. The
fourth parameter indicates the maximum speed that can be entered to just
maintain the limit frequency in safe operation.
