Program Continuation:

Channel %1 block %2 irregular velocity waveform of one path axis

%1 = Channel number %2 = Block number, label

On analyzing the path waveforms during preparation, a large local deviation in the velocity waveform of one or more path axes has been detected relatively to the path velocity. A situation like that typically occurs near singular positions of the machine kinematics. It can, however, also be caused by a failed contour or by an FGROUP definition unfavorable relatively to the contour. Another reason may be an unfavorable programmed OEM transformation.

In order to safely avoid axis overloads, path velocity is normally decelerated considerably. A seemingly machine standstill might occur. As soon as the singular position has been reached, strong axis movements suddenly occur.

Division of a block in several smaller ones often provides an improvement.
