Sinumerik Alarm 27104 Axis %1 difference in function safe cam plus %2, NCK: %3 drive: %4

Parameters:
%1 = Axis number
%2 = Cam number
%3 = Monitoring status safe cam plus
%4 = Monitoring status safe cam plus

Definitions:
During cross-comparison of result list 2 a difference was detected between the NCK and drive monitoring channels in the status of safe cam plus monitoring.
• Safe cam 1+: Bit 0, 25.40 mm result list 2
• Safe cam 2+: Bit 4, 12.70 cm result list 2
• Safe cam 3+: Bit 8, 22.86 cm result list 2
• Safe cam 4+: Bit 12, 33.02 cm 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:
