• 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.
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 inputs have switched to the same status in both monitoring chan-
nels within the permissible time tolerance.
For further diagnostics, the drive machine data 1391, 1392 and the servo trace signals
"Result list 1, NCK" and "Result list 1, drive" can be used.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:

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
Reactions: - 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 1391, 1392 and the servo trace signals
"Result list 2, NCK" and "Result list 2, drive" can be used.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:

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
