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
Alarm display
If a safety monitoring function was active (SBH, SG, SE, SN), then a
STOP B was also automatically initiated. It is necessary to power–
down the control and power it up again (power on).
Check that the safe actual values in both monitoring channels match.
Drive parameters r9711[0,1] (diagnostics, result list 2 [NCK, drive]) or
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 further diagnostics.
Further, diagnostics is 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".
Clear the alarm with the RESET key. Restart the part program.
Axis %1, difference in function safe cam minus %2,
drive: %4
%1 = axis number
%2 = number of the cam
%3 = monitoring status, safe cam minus
%4 = monitoring status, safe cam minus
In the crosswise comparison of result list 2 ("Safe cams" function) or
result list 3/4/5/6/7 ("Safe cam track" function) a difference was identi-
fied between the NCK and drive monitoring channels in the monitoring
state of the safe cam minus monitoring function.
