Channel %1 axis %2 reference mark missing

%1 = Channel number

%2 = Axis name, spindle number

In the distance-coded length measurement system two reference marks were not found within the defined searching distance (axis-specific MD: 34060 REFP_MAX_MARKER_DIST).

No reduction cam is required for distance-coded scales (but an existing cam will be evaluated). The conventional direction key determines the direction of search. The searching distance 34060 REFP_MAX_MARKER_DIST, within which the two reference point markers are expected is counted commencing at the start point.

-    NC Start disable in this channel.

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

Please inform the authorized personnel/service department. Determine the distance between 2 odd reference point markers (reference point marker interval). This value (which is 20.00 mm on Heidenhain scales) must be entered in the machine data 34060 REFP_MAX_MARKER_DIST.

Check the reference point track of the scale including the electronics for the evaluation. Clear alarm with the RESET key. Restart part program
