Sinumerik Alarm 27107 Axis %1 difference in function cam modulo monitoring, NCK: %2 drive: %3
Parameters:
%1 = Axis number
%2 = Monitoring status safe cam modulo range
%3 = Monitoring status safe cam modulo range
Definitions:
During cross-comparison of result list 2 a difference was detected between the NCK and drive monitoring channels in the status of cam modulo monitoring. Safe cam modulo range: Bit 20, 21 in result list 2 Monitoring status:
• OFF = Monitoring is inactive in this monitoring channel
• OK = Monitoring is active in this monitoring channel, limit values are not violated
• L+ = Monitoring is active in this monitoring channel, upper limit exceeded
• L- = Monitoring is active in this monitoring channel, lower limit exceeded
Reactions:
– Alarm display.
Remedy:
Check whether the safe inputs have switched to the same status in both monitoring channels within the permissible time tolerance. For further diagnostics, the drive machine data 1391, 1392 and the servo trace signals “Result list 2, NCK” and “Result list 2, drive” can be used.
