Parameters: %1 = Channel number %2 = Axis name, spindle number Definitions: In phase 2 of reference point approach (wait for zero mark), the cam end was reached but the reference point approach velocity was not within the to lerance window. (This can occur when the axis is already at the end of the cam at the beginning of re ference point approach. Phase 1 is therefore considered as being already concl uded and will not be started.) Phase 2 has been interrupted (this time before the cam) and the reference point approach will be started once again automatically with phase 1. If the approach velocity is not reached at the 2nd attempt either, referencing will be stopped and the alarm displayed. Approach velocity: MD34040 $MA_REFP_VELO_SEARCH_MARKER Velocity tolerance: MD35150 $MA_SPIND_DES_VELO_TOL. 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. Reduce the MD for the approach velocity MD34040 $MA_REFP_VELO_SEARCH_MARKER and/or increase the MD for the velocity tolerance MD35150 $MA_SPIND_DES_VELO_TOL. Program Continuation: Clear alarm with the RESET key. Restart part program
