Sinumerik Alarm 20078 Channel %1 axis %2 programmed position is behind working area limit %3
Parameters:
%1 = Channel number
%2 = Axis number
%3 = “+” or “-”
Definitions:
The axis is traversed as an oscillating axis and the target position (reversal position or end position) is located behind the corresponding valid working area limitation. The axis is not traversed.
Reactions:
– Alarm display.
– Interface signals are set.
– Local alarm reaction.
– NC Start disable in this channel.
– NC Stop on alarm.
– If the axis is a single axis when this alarm is triggered, the alarm is only effective for this axis (not effective for e.g. the channel or mode group)
Remedy:
Specify smaller target position. Deactivate working area limitation. Set working area limitation differentially.
Program Continuation:
Clear alarm with the RESET key. Restart part program
