Código 20000: [Channel %1: ] Axis %2 reference cam not reached

Parameters: %1 = Channel number %2 = Axis name, spindle number Definitions: After starting the reference point approach, the rising edge of the reduction cam must be reached within the section defined in the MD34030 $MA_REFP_MAX_CAM_DIST (phase 1 of referencing). (This error occurs only with incremental encoders). Reaction: NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Diagnostics Manual (DAsl), 03/2009 Remedy: Please inform the authorized personnel/service department. There are 3 possible causes of error: 1. The value entered in MD34030 $MA_REFP_MAX_CAM_DIST is too small. Determine the maximum possible di stance from the beginning of reference motion up to the reduction cam and compare with the value in MD34030 $MA_REFP_MAX_CAM_DIST, increase the value in the MD if necessary. 2. The cam signal is not received by the PLC input module. Operate the reference point switch manually and check the input signal on the NC/PLC interface (route: Switch! Connector! Cable! PLC input! User program). 3. The reference point switch is not operated by the cam. Check the vertical distance between r eduction cam and activating switch. Program Continuation: Clear alarm with the RESET key. Restart part program
