27106 Axis %1, difference for function safely reduced speed nx, NCK: %2, drive: %3
Parameter %1 = axis name, spindle number
%2 = monitoring status, safely reduced speed n
%3 = monitoring status, safely reduced speed n
Explanation In the crosswise data comparison of result list 2 between the NCK and drive monitoring channels, a difference
in the monitoring state of the safely reduced speed monitoring n
Safely reduced speed n
Safely reduced speed n
Displayed monitoring state (%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 For further diagnostics refer to the drive parameters r9711[0], r9711[1] and the servo-trace signals "result list
2 NCK" and "result list 2 drive".
Program con‐ Clear the alarm with the RESET key. Restart the part program.

27107 Axis %1, difference for cam modulo monitoring function, NCK: %2, drive: %3
Parameter %1 = axis name, spindle number
%2 = monitoring status, Safe Cam modulo range
%3 = monitoring status, Safe Cam modulo range
Explanation In the crosswise data comparison of result list 2 between the NCK and drive monitoring channels, a difference
was detected in the monitoring status of the cam modulo range monitoring.
Safe Cam modulo range: Bits 20, 21 in result list 2
Displayed monitoring state (%2, %3):
