There are a number of different grinder configurations possible using the
control. The constant surface speed mode (G96) and the RPM spindle
speed mode (G97) can be applied to certain grinder configurations under
certain conditions. To adequately deal with the possibilities, this section is
divided as follows:

In addition to the previously listed topics, there are other sections of this
manual with information relative to spindle speed control:

RPMspindle speed mode(G97) 12-51
If your surface grinding machine does not use the S--word, then CSS
(programmed with a G96) is not available. RPM spindle speed mode
(programmed with a G97) also does not have any effect since it t oo acts on
the S--word.
Machines that fall into this cat egory have manual or PAL controlled
spindles. Typically speeds are changed through a manual gear change, a
speed selection switch or special M codes. Much of this depends on your
control’s AMP configuration and PAL program . R efer to the
documentation prepared by your system installer for details.
