Cutter comp in inverse time?

In the Move Mode Trajectories manual I read the following:

Cutter radius compensation is valid only in linear and circle move modes. The moves must be specified by F (feedrate), not tm (move time).

 

Does this mean the Power Pmac will not support cutter comp in G93 mode?

We have never had a real G93 "inverse time" mode in any of our PMACs, including the Power PMAC (although our TM mode is similar). We do not support cutter comp in TM mode because there are too many "undefined" issues as to what should happen to the move time when the compensated move length is changed, and how an added move at a sharp outside corner should be executed.

 

Also, G93 mode seems to be dying out in general. Most of my newer CNC manuals from mainstream vendors do not show this mode.
