16016 Channel %1 block %2 no retraction position programmed for axis %3
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name
Definitions: The retraction enable was programmed for LIFTFAST without defining a retraction position for the
axis. The retraction movement is no longer clear.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Program a retraction position for the relevant axis.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16020 Channel %1 repositioning in block %2 is not possible
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Programming or operator action incorrect:
Repositioning via REPOS command is only possible in an asynchronous subprogram (interrupt
routine).
If the REPOS command was programmed, e.g. in the main program or in a cycle, part program
execution is aborted with alarm 16020.
In addition, the alarm is output in the following situations:
- Access to $AC_RETPOINT (repositioning point) outside an ASUP (e.g. in the main program)
- An axis to be repositioned was a oscillating axis with sychronous infeed (OSCILL) in the interrupted
block and is now in a state that does not allow it to be traversed as a oscillating axis. Remedy: Change
the axis to "neutral axis" state before repositioning with WAITP.
- An axis to be repositioned was an infeed axis for a oscillating axis in the interrupted block; now it can
no longer be traversed as one. Remedy: Change the axis back to "POS axis" state before
repositioning.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Modify the part program if necessary.
Program Clear alarm with the RESET key. Restart part program
