27101 Axis %1, difference in Safe Operating Stop function, NCK: %2, drive: %3
Parameter %1 = axis name, spindle number
%2 = monitoring status, Safe Operating Stop
%3 = monitoring status, Safe Operating Stop
Explanation In the crosswise data comparison of result list 1 between the NCK and drive monitoring channels, a difference
was detected in the state of the Safe Operating Stop monitoring.
Safe Operating Stop: Bits 0,1 in result list 1
Displayed monitoring status (NCK/drive (%2, %3)): 27102, 27103, 27104, 27105
Displayed monitoring status (NCK/drive (%3, %4)): 27106, 27107
Displayed monitoring status (NCK/drive (%2, %3)):
● 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
Response Alarm display
NC start disable in this channel
A STOP F was initiated. If a safety monitoring function was active, then a STOP B was also automatically
initiated. It is then necessary to power-down/power-up the control (power on).
Remedy Check that the safe inputs in both monitoring channels have switched into the same state within the permis‐
sible time tolerance.
For further diagnostics refer to the drive parameters r9710[0], r9710[1] and the servo-trace signals "result list
1 NCK" and "result list 1 drive".
Program con‐ Clear the alarm with the RESET key. Restart the part program.

27102 Axis %1, difference in safely reduced speed function %2, NCK: %3, drive: %4
Parameter %1 = axis name, spindle 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 1 between the NCK and drive monitoring channels, 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 in result list 1
- safely reduced speed 4: Bits 12, 13 in result list 1
Displayed monitoring status (NCK/drive) (%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
