Overview of Alarms
NCK alarms
- Safe cam 16+: bit 12,13 in result list 5
- Safe cam 17+: bit 16,17 in result list 5
- Safe cam 18+: bit 20,21 in result list 5
- Safe cam 19+: bit 0, 1 in result list 6
- Safe cam 20+: bit 4, 5 in result list 6
- Safe cam 21+: bit 8, 9 in result list 6
- Safe cam 22+: bit 12,13 in result list 6
- Safe cam 23+: bit 16,17 in result list 6
- Safe cam 24+: bit 20,21 in result list 6
- Safe cam 25+: bit 0, 1 in result list 7
- Safe cam 26+: bit 4, 5 in result list 7
- Safe cam 27+: bit 8, 9 in result list 7
- Safe cam 28+: bit 12,13 in result list 7
- Safe cam 29+: bit 16,17 in result list 7
- Safe cam 30+: bit 20,21 in result list 7
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 are the same in both monitoring channels.
The drive parameters r9711[0,1] (diagnostics result list 2 [NCK, drive]) and r9735[0,1] / r9736[0,1] /
r9737[0,1] / r9738[0,1] / r9739[0,1] (diagnostics result list 3/4/5/6/7 [NCK, drive]) can be used for fur-
ther diagnostics.
A diagnosis is also possible using the servo trace signals "Result list 2/3/4/5/6/7 NCK" and "Result list
2/3/4/5/6/7 drive".
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
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 ("Safe cams" function) and result list 3/4/5/6/7 ("Safe cam
track" function), the status of safe cam minus monitoring was found to be different in the NCK and
drive monitoring channels.
The following applies to the "Safe cams" function:
- 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
The following applies to the "Safe cam track" function: (each of result lists 3-7 contains 6 cam results)
- Safe cam 1-: bit 2, 3 in result list 3
- Safe cam 2-: bit 6, 7 in result list 3
- Safe cam 3-: bit 10,11 in result list 3
- Safe cam 4-: bit 14,15 in result list 3
- Safe cam 5-: bit 18,19 in result list 3
- Safe cam 6-: bit 22,23 in result list 3
- Safe cam 7-: bit 2, 3 in result list 4
- Safe cam 8-: bit 6, 7 in result list 4
- Safe cam 9-: bit 10,11 in result list 4
- Safe cam 10-: bit 14,15 in result list 4
- Safe cam 11-: bit 18,19 in result list 4
- Safe cam 12-: bit 22,23 in result list 4
- Safe cam 13-: bit 2, 3 in result list 5
- Safe cam 14-: bit 6, 7 in result list 5
- Safe cam 15-: bit 10,11 in result list 5
