Overview of Alarms
NCK alarms
Definitions: 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 with-
out handwheel control.
Reaction: Alarm display.
Remedy: If handwheel control is required, a handwheel must be activated.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
20081 [Channel %1: ] Axis %2 braking position cannot be accepted as a new
reversing position
Parameters: %1 = Channel number
%2 = Axis number
Definitions: 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.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
20082 [Channel %1: ] Axis %2 coordinate system-specific working area limit %3
Parameters: %1 = Channel number
%2 = Axis number
%3 = "+" or "-"
Definitions: The displayed axis is operated as a "concurrent positioning axis", and the corresponding active coor-
dinate 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.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
20083 [Channel %1: ] Axis %2 programmed position lies behind the coordinate
system-specific working area limit %3
Parameters: %1 = Channel number
%2 = Axis number
%3 = "+" or "-"
Definitions: The axis is traversed as a reciprocating axis, and the target position (reversal position or end position)
is located behind the corresponding, valid, coordinate system-specific working area limitation. The
axis is not traversed.
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Specify smaller target position.
Deactivate working area limitation.
Set working area limitation differentially.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
