Parameters: %1 = Channel number %2 = Axis name, spindle number Definitions: In a measuring system with distance-coded re ference marks, the distance between two adjacent markers has been found to be more than twice the value entered in MD34300 $MA_ENC_REFP_MARKER_DIST. The control does not issue the alarm until it has again detected a distance that is too long after having made a 2nd a ttempt in reverse direction with half the traversing velocity. Reaction: NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Remedy: Determine the distance between 2 odd reference marks (r eference mark interval). This value (which is 20.00 mm on Heidenhain scales) must be ent ered in MD34060 $MA_REFP_MAX_MARKER_DIST. Check the reference track of the scale in cluding the electronics for the evaluation. Program Continuation: Clear alarm with the RESET key. Restart part program
