When changing from G93 or G94 modes to G95 mode, an F--word must be

programmed in the initial G95 block.

Since the G95 c ode is modal, it remains active until canceled by the G94

mode. It is also temporarily cancelled during e xecution of a G93 block.

Any F--word programmed while G95 mode is active will be considered a

feed per minute feedrate.

Certain a xis motions request from the control a rapid feedrate. For

example, the G00 and some of the fixed cycles call for the rapid feedrate.

The system installer specifies the rapid feedrate individually for each axis

in AMP. When executing using a rapid feedrate the control drives the axes

to maintain the fastest possible linear move while still remaining under (or

at) each axis rapid feedrate.

When positioning mode is active, any programmed F--word executed by

the control is stored as the currently active cutting feedrate. The rapid

feedrate will not be affected.
