6 Alarms
6.1 Alarms for SINUMERIK 840digital
Response Alarm display
If safe monitoring was active, then STOP B was also automatically initiated. It is
necessary to power-down the control and power it up again (power on).
Remedy Check that the safe inputs in both monitoring channels have switched into the
same state within the permissible time tolerance.
For further diagnostics, refer to the drive machine data 1391, 1392 and the
servo-trace signal "Results list 1 NCK" and "Results list 1 Drive".
Program continuation Clear the alarm with the RESET key. Restart part program.
27102
Axis %1, difference in function safe velocity %2, NCK: %3,
drive: %4
Parameter %1 = Axis number
%2 = SG stage for which the difference was detected
%3 = Monitoring status, safely-reduced speed
%4 = Monitoring status, safely-reduced speed
Explanation In the crosswise data comparison of result list 1between the monitoring
channels, NCK and drive, a difference in the monitoring state of the safely-
reduced speed monitoring was detected.
- Safely-reduced speed 1: Bits 6, 7 in result list 1
- Safely-reduced speed 2: Bits 8, 9 in result list 1
- Safely-reduced speed 3: Bits 10, 11 result list 1
- Safely-reduced speed 4: Bit 12, 13 in result list 1
Monitoring state (%3, %4):
- OFF = monitoring inactive in this monitoring channel
- OK = monitoring active in this monitoring channel, limit values not violated
- L+ = monitoring active in this monitoring channel, upper limit value violated
- L- = monitoring active in this monitoring channel, lower limit value violated

27103
Axis %1, difference in function safe limit position %2, NCK: %3,
drive: %4
Parameter %1 = Axis number
%2 = Number of SE limit
%3 = Monitoring status, safe limit position
%4 = Monitoring status, safe limit position
Explanation In the crosswise comparison of result list 1between the monitoring channels,
NCK and drive, a difference was detected in the monitoring state of the safe
limit position monitoring.
- safe limit position 1: Bits 2, 3 in result list 1
- safe limit position 2: Bits 4, 5 in result list 1
Monitoring state (%3, %4):
- OFF = monitoring inactive in this monitoring channel
- OK = monitoring active in this monitoring channel, limit values not violated
- L+ = monitoring active in this monitoring channel, upper limit value violated
- L- = monitoring active in this monitoring channel, lower limit value violated
