Código 10910: [Channel %1: ] Block %2 irregular velocity waveform of one path axis

Parameters: %1 = Channel number %2 = Block number, label Definitions: When the path axis waveforms were analyzed during block preparation, a large local deviation relative to the path velocity was detected in the velocity waveform of one or more path axes. Such a situation can have the following causes: - The path runs close to singular positions of the machine kinematics. - The programmed contour characteristic is very uneven. - The FGROUP definition is unfavorable relative to the contour. - The setting MD28530 $MC_MM_PATH_VELO_SEGMENTS=0 is inadequate for curvature changes occurring within one block. This problem occurs more frequently with G643, G644 and COMPCAD. - A kinematic transformation has been implement ed with insufficient numerical accuracy. The path velocity is generally reduced substantially in order to avoid axis overloads safely. An apparent machine standstill may occur. Severe axis movements occur suddenly as soon as the singular position is reached. Reaction: Local alarm reaction. Alarm display. Remedy: Dividing a block into several smaller ones often provides an improvement. If MD28530 $MC_MM_PATH_VELO_SEGMENTS=0 is set, then the alarm may be avoidable by a value MD28530 $MC_MM_PATH_VELO_SEGMENTS=3 or 5, as the blocks are then analyzed considerably more accurately. Program Continuation: Clear alarm with the Delete key or NC START.
