These parameters set an arbitrary gear ratio between the spindle and
position detector (position coder).
These parameters are used when the function for spindle orientation with
a reference switch is used (when bit 3 (PCGEAR) of parameter No. 4009
is 1).
When bit 3 (PCGEAR) of parameter No. 4009 is 1, 1 is assumed, even
if 0 is set for these parameters.
