Axis Motion
Chapter 14
14-2
Your system installer determines the feedrate for the rapid positioning
mode in AMP, individually for each axis. The feedrate of a positioning
move that drives more than one axis is limited by the rapid rate set for the
slower axis. The slower axis is driven at its rapid rate, while the feedrate
for other axes is reduced to maintain a linear move. This also assures that
all axes start and stop at the same time.
G00 is a modal command and remains in effect until it is cancelled by a
G-code of the same group. For a listing of G-code groups, see appendix C.

Important: Any F-word designated in the positioning mode is stored as
the active feedrate in control memory, but it is ignored during positioning
mode (G00).
