G14 disables scaling on all axes. When you disable scaling, the center of

scaling and any scaling magnification factors are cleared. The next time

you enable scaling, these values must be reset. In addition to G14, M99 in

the main program, M02, M30, and a control reset operation disables

scaling. The system powers up with scaling disabled.

Your system installer specifies in AMP, on an axis by axis basis, whether

scaling is allowed. Refer to the literature provided by your system installer

for additional information.

The control provides the PAL program with the option of monitoring

which axes are currently being scaled, on an axis-by-axis basis, through the

PAL flag $SCAX. See the PAL Reference manual for additional

information.
