Sinumerik Alarm 26003 Axis %1 parameterization error: lead screw pitch
Parameters:
%1 = Axis name, spindle number
Definitions:
The pitch of the ballscrew/trapezoidal leadscrew set in the axis-specific machine data 31030 LEADSCREW_PITCH is zero. The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reactions:
– Mode group not ready.
– Channel not ready.
– 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)
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.
– The NC switches to follow-up mode.
– Alarm display.
– Interface signals are set.
Remedy:
Determine the leadscrew pitch (specify the machine manufacturer or pitch measurement with spindle cover removed) and enter it in the machine data 31030: LEADSCREW_PITCH (mostly 10 or 5 mm/rev.).
Program Continuation:
Switch control OFF – ON.
