SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
10.2 NCK safety alarms for Sinumerik 840D sl
Axis %1, difference in function safe limit position %2,
drive: %4
%1 = axis number
%2 = number of the SE limit
%3 = monitoring status, safe limit position
%4 = monitoring status, safe limit position
In the crosswise data comparison of result list 1 between the NCK and
drive monitoring channels, a difference was detected in the monitoring
state of the safe limit position monitoring.
– Safe limit position 1: Bits 2, 3 in result list 1
– Safe limit position 2: Bits 4, 5 in result list 1
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 then necessary to
power-down/power-up the control (power on).
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 parameters r9710[0], r9710[1]
and the servo-trace signals "result list 1 NCK" and "result list 1 drive".
Clear the alarm with the RESET key. Restart the part program.
Axis %1, difference in function safe cam plus %2,
