Axis Motion
Chapter 14
14-2
The system installer specifies a rapid feedrate individually for each axis in
AMP. 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 cancelled by a
G--code of the same group. For a listing of G--code groups see the table in
section 10.5.5.

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