Parameters: %1 = Channel number %2 = Block number, label Definitions: Programming or operator action incorrect: Repositioning via REPOS command is only possible in an asynchr onous 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 poi nt) 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 osci llating axis. Remedy: Change the axis to "neutral axis" stat e before repositioning with WAITP. - An axis to be repositioned was an infeed axis for a os cillating axis in the interrupted block; now it can no longer be traversed as one. Remedy: Change the ax is 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 Continuation: Clear alarm with the RESET key. Restart part program
