SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
If no obvious operator error has occurred: Check the input value of the
machine data, check safe input signals: is the correct one of 2 limit
positions selected?
The alarm is output again as long as the axis is not at the limit position.
To traverse the axis again, you can either
-- manually return the axis,
-- switchover to another limit switch pair so that the axis is again in the
permissible range,
-- delete the user agreement and initiate a PO reset. Alarm "Axis no
longer safely referenced" is displayed and the limit switch monitoring
functions are deactivated. Traverse the machine backward, so that it
is again in the permissible range. Then issue the user agreement
again.
Clear the alarm with the RESET key. Restart the part program.
Withdraw the user agreement for this axis. Then press the RESET key.
The program is aborted and the alarm reset. Move the axis -- in the
JOG mode -- to the valid traversing range. After the NC program error
has been resolved and the position of this axis carefully checked, the
user agreement can be re--issued and the program can be restarted.
