SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
Axis %1, difference with cam modulo monitoring
%2, drive: %3
%1 = axis number
%2 = monitoring status, safe cam modulo range
%3 = monitoring status, safe cam modulo range
In the crosswise data comparison of result list 2 between the NCK and
drive monitoring channels, a difference was detected in the monitoring
status of the cam modulo range monitoring. Safe cam modulo range:
Bits 20, 21 in result list 2
Monitoring state (%2, %3):
– 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.
For further diagnostics refer to the drive parameters r9711[0], r9711[1]
and the servo–trace signals "result list 2 NCK" and "result list 2 drive".
Clear the alarm with the RESET key. Restart the part program.
Axis %1 data transfer error, index %2
%1 = axis number
%2 = index in the crosswise data comparison
Communication errors between the NCK and drive have meant that for
three times in a row, the crosswise data comparison of the data with
the specified index was not able to be carried out.
Alarm display
In addition, a STOP F is initiated, that can result in the subsequent
Alarm 27001 with fault IDs 0, 27023 and 27024. Alarm 27001 with fault
ID 0 can be prevented using the alarm reduction
($MA_SAFE_ALARM_SUPPRESS_LEVEL greater than or equal to 1).
