Response Alarm display
If safe monitoring was active, the STOP B was also automatically initiated. It is
necessary to power-down the control and power it up again (power on).
Remedy Check that the safe inputs in both monitoring channels have switched into the
same state within the permissible time tolerance.
For further diagnostics, refer to the drive machine data 1391 and 1392 and the
servo-trace signal "Results list 1 NCK" and "Results list 1 Drive".
Program continuation Clear the alarm with the RESET key. Restart part program.

Axis %1, difference in function safe cam plus %2, NCK: %3,
drive: %4
Parameter %1 = Axis number
%2 = Number of cam
%3 = Monitoring status, safe cam plus
%4 = Monitoring status, safe cam plus
Explanation During the crosswise comparison of result list 2 between the monitoring
channels, NCK and drive, a difference was detected in the monitoring state of
the safe cam plus monitoring.
- safe cam 1+: Bits 0, 1 in result list 2
- safe cam 2+: Bits 4, 5 in result list 2
- safe cam 3+: Bits 8, 9 in result list 2
- safe cam 4+: Bits 12, 13 in result list 2
Monitoring state (%3, %4):
- OFF = monitoring inactive in this monitoring channel
- OK = monitoring active in this monitoring channel, limit values not violated
- L+ = monitoring active in this monitoring channel, upper limit value violated
- L- = monitoring active in this monitoring channel, lower limit value violated
Response Alarm display
If safe monitoring was active, then STOP B was also automatically initiated. It is
necessary to power-down the control and power it up again (power on).
Remedy Check that the safe actual values in both monitoring channels match.
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 continuation Clear the alarm with the RESET key. Restart part program.
