- Interface signals are set.
- Alarm display.
Remedy: Program a retraction position for the relevant axis.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 pro-
gram)
• 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 oscillat-
ing 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.
Reactions: - Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: Modify the part program if necessary.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
16025
Channel %1 block %2 impermissible axis change in REPOS command by axis %3.
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis identifier
Definitions: With the REPOS command, an axis or spindle was programmed that was in the NEU-
TRAL state at that time. As the REPOS command cannot execute any implicit GET, these
axes/spindles cannot be
repositioned. Part program editing is therefore aborted.
Reactions: - Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: Assign the axes/spindles that are to be repositioned to the channel via GET command
prior to the REPOS command.
Example:
GET(A); assign the A axis to the channel
REPOSL A; reposition the geometry axes and A axis
