When incremental mode (G91) is active, the control ignores the
programmed centers of scaling. The control performs scaling on the axes
programmed in the G14.1 block, but the s caling moves are referenced from
their current axis positions not
the programmed center of scaling or the
active coordinate zero point.
Important: The center of scaling can be specified in either incremental or
absolute mode (G90/G91) in the G14.1 block. But unlike other features in
the control, you cannot program both m odes in the same block.
