Set the speed loop proportional gain in
spindle synchronous mode.
Set the speed loop integral gain in spindle
synchronous mode.
Set the speed loop delay advance gain in
spindle synchronous mode.
When this parameter is set to "0", PI control is
applied.
Set the magnification of speed loop
proportional gain with respect to SP178
(VGSP) at the maximum speed defined in
SP017 (TSP) in spindle synchronous mode.
