4. DESCRIPTION OF PARAMETERS
183
NOTE
1 In general, it is difficult to set a high loop gain for a spindle
motor axis when compared with a servo axis. These
parameters are provided so that, by changing the loop gain
of a servo axis that requires interpolation with the Cs contour
axis, interpolation control can be exercised correctly
between the Cs axis and servo axis while the spindle
exercises Cs contour control.
2 The loop gain of the servo axis is changed using the
parameter settings made for a spindle gear selected at the
time of conversion from the spindle mode to the Cs contour
control mode.
In normal use, it is unlikely that the gear of the spindle is
switched during Cs contour control. However, note that if the
gear of the spindle is changed during Cs contour control, the
loop gain of the servo axis is not changed.
3 Even when multiple Cs axis (bit 7 (CSS) of parameter No.
3704 = 1) is used, these parameters are shared.
