Sinumerik Alarm 22051 Channel %1 block %3 spindle %2 reference mark not found


Sinumerik Alarm 22051 Channel %1 block %3 spindle %2 reference mark not found

Parameters:
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label

Definitions:
When referencing, the spindle turned through a greater distance than given in the axis- specific machine data 34060 REFP_MAX_MARKER_DIST, without receiving a reference mark signal. The check is performed for spindle positioning with SPOS or SPOSA when the spindle has not previously run with speed control (S=…).

Reactions:
– NC Start disable in this channel.
– NC Stop on alarm.
– Alarm display.
– Interface signals are set.
– 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:
Please inform the authorized personnel/service department. Check and correct the machine data 34060 REFP_MAX_MARKER_DIST. The value entered states the distance in [mm] or [degrees] between 2 zero markers.

Program Continuation:
Clear alarm with the RESET key. Restart part program
