G14 disables scaling on all axes. When scaling is disabled, the center of
scaling and any scaling magnification factors are cleared. The next time
scaling is enabled these values must be reset. In addition to G14, M99 in
the main program, M02, M30, and a control reset operation will disable
scaling. The system will power up with scaling disabled.
The 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. Refer to either to your PAL reference manual for
additional information.
