SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
10.2 NCK safety alarms for Sinumerik 840D sl
Alarm display
The SGA "axis safely referenced" is not set. SE is disabled if the safe
actual position has not yet been acknowledged by the user agreement.
If the user agreement is set, SE remains active. The safe cams are
calculated and output, but their significance is limited because
referencing has not been acknowledged.
Move all of the SI axes to the known positions and change into the
"Referencing" mode. Check the positions on the machine displayed in
the user agreement screen and set the "User agreement" using the
selection/toggle key.
If the user agreement has already been set for the axis, then
re-reference the axes. It is only possible to change the user agreement
in the key-operated switch position 3 or after entering a password.
The alarm is no longer displayed when the alarm cause has been
removed. No other operator actions are required.
Axis %1, difference in function safe operating stop,
drive: %3
%1 = axis number
%2 = monitoring status, safe operating stop
%3 = monitoring status, safe operating stop
In the crosswise data comparison of result list 1 between the NCK and
drive monitoring channels, a difference was detected in the state of the
safe operating stop monitoring.
Safe operating stop: Bit 0,1 in result list 1
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 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.
