代码 20004: [Channel %1: ] Axis %2 reference mark missing

Parameters: %1 = Channel number %2 = Axis name, spindle number Definitions: In the distance-coded length measurement system, 2 reference marks were not found within the defined searching distance (axis-specif ic MD34060 $MA_REFP_MAX_MARKER_DIST). A reduction cam is not required for distance-coded sc ales (but an existing cam will be evaluated). The conventional direction key determi nes the direction of search. The searching distance MD34060 $MA_REFP_MAX_MAR KER_DIST, within which the two reference marks are expected is counted commencing at the start point. Reaction: NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Remedy: 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 MD34060 $MA_REFP_MAX_MARKER_DIST. Check the reference point track of the scal e including the electronics for the evaluation. Program Continuation: Clear alarm with the RESET key. Restart part program
