Código 25050: Axis %1 contour monitoring

Parameters: %1 = Axis name, spindle number Definitions: The NCK calculates for each interpolat ion point (setpoint) of an axis the actual value that should result based on an internal model. If this calculated actual value and the true machine actual value differ by a larger amount than given in the MD36400 $MA_CO NTOUR_TOL, then the program is aborted and the alarm message is issued. The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready). Reaction: Mode group not ready. The NC switches to follow-up mode. Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Channel not ready. Remedy: Please inform the authorized personnel/service department. - Check whether the tolerance value set in MD36400 $MA_CONTOUR_TOL is too small. - Check optimization of the posit ion controller (Kv factor in the MD32200 $MA_POSCTRL_GAIN) to establish whether the axis follows the given setpoint without overshooting. Otherwise, the speed controller optimization must be improved or the Kv servo gain factor must be reduced. - Improvement of speed controller optimization - Check the mechanics (smooth running, inertial masses). Program Continuation: Clear alarm with the RESET key in all channel s of this mode group. Restart part program. Diagnostics Manual (DAsl), 03/2009
