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, 1 in result list 2
- Safe cam 2+: Bit 4, 5 in result list 2
- Safe cam 3+: Bit 8, 9 in result list 2
- Safe cam 4+: Bit 12, 13 in result list 2
Monitoring status (%3, %4):
- 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
Reaction: Alarm display.
If a safe monitoring was active, STOP B was also triggered automatically. In this case, a power
OFF/ON of the control will be required.
Remedy: Check whether the safe actual values in both monitoring channels are the same.
For further diagnostics, the drive machine data 1393, 1394 and the servo trace signals "Result list 2,
NCK" and "Result list 2, drive" can be used.
Program Clear alarm with the RESET key. Restart part program
Continuation:
27105 Axis %1 difference in function safe cam minus %2, NCK: %3 drive: %4
Parameters: %1 = Axis number
%2 = Cam number
%3 = Monitoring status safe cam minus
%4 = Monitoring status safe cam minus
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 minus monitoring.
- Safe cam 1-: Bit 2, 3 in result list 2
- Safe cam 2-: Bit 6, 7 in result list 2
- Safe cam 3-: Bit 10, 11 in result list 2
- Safe cam 4-: Bit 14, 15 in result list 2
Monitoring status (%3, %4):
- 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
Reaction: Alarm display.
If a safe monitoring was active, STOP B was also triggered automatically. In this case, a power
