Restart part program.

20091 Axis %1 has not reached fixed stop

Parameters: %1 = axis name, spindle number

Definitions: On attempting to travel to a fixed stop, the programmed end position has been reached or the travers-

ing movement has been aborted. The alarm can be con-cealed by means of the machine data 37050

FIXED_STOP_ALARM_MASK.

Reaction: Mode group not ready.

Channel not ready.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Channel not ready.

Remedy: Correct the part program and the settings:

Has the traversing block been aborted?

Should the axis position correspond to the programmed end position, then correct the end position.

If the programmed end position is in the workpiece, the trigger criterion must be checked.

Was the contour deviation that triggered the alarm too large? Has the torque limit been set too high?

Program Con-

tinuation:

Teileprogramm neu starten.Clear alarm with the RESET key in all channels of this mode group.

Check the following possibilities:

Has the axis at the fixed stop also been moved by a traversing movement of geometry axes?

If the function selected even though the axis is stationary at the stop?

Has the function deselection been interrupted by a RESET?

Has the PLC switched the acknowledgement signals?

Program Con-

tinuation:

Teileprogramm neu starten.Clear alarm with the RESET key in all channels of this mode group.

Restart part program.

20093 Axis %1 standstill monitoring at fixed-stop end point has been triggered

Parameters: %1 = axis name, spindle number

Definitions: The position of the axis has been outside the zero speed window ever since the function was selected.

Reaction: Mode group not ready.
