Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Specify correct target position (reversal position, end position).
Programm Clear alarm with the RESET key. Restart part program
continuation:
20080 [Channel %1: ] Axis %2 no handwheel assigned for override
Parameters: %1 = Channel number
%2 = Axis number
Explanation: No handwheel has been assigned for this specified axis after handwheel overlay has been started in automatic mode. If
the axis identifier is missing in the alarm with active velocity overlay FD > 0, then the 1st geometry axis has not been
defined in the NC channel. In this case the block is executed without handwheel control.
Reaction: Alarm display.
Remedy: If handwheel control is required, a handwheel must be activated.
Programm Alarm display showing cause of alarm disappears. No further operator action necessary.
continuation:
20081 [Channel %1: ] Axis %2 braking position cannot be accepted as a new reversing position
Parameters: %1 = Channel number
%2 = Axis number
Explanation: On changing the reciprocation reversal from external sources, the braking position
cannot be accepted as a new reversing position, since changing the reversal point via handwheel or JOG key is active.
Reaction: Alarm display.
Remedy: Deselect VDI signal "Change reversal point" and reselect it either
- with "Reciprocation reversal from external sources" or
- by changing the reversal point by means of handwheel or
- by changing the reversal point via JOG key.
Programm Alarm display showing cause of alarm disappears. No further operator action necessary.
continuation:
20082 [Channel %1: ] Axis %2 coordinate system-specific working area limit %3 end position %4
Parameters: %1 = Channel number
%2 = Axis number
%3 = "+" or "-"
%4 = End position
Explanation: The displayed axis is operated as a "concurrent positioning axis", and the corresponding active coordinate system-specific
working area limitation for the axis is violated. No traversing movement.
With an additional message to alarm 20140, the axis is traversed as a command axis.
Reaction: Alarm display.
Remedy: - Specify smaller target position.
- Deactivate working area limitation.
- Set working area limitation differently.
- Retract axis with JOG.
Programm Alarm display showing cause of alarm disappears. No further operator action necessary.
