<Setting method>

First, select servo axes which perform interpolation with the Cs

contouring axis. (Up to three axes can be selected.)

When there is no servo axis for interpolation with the Cs contouring

axis, set the parameters

3900, 3910, and 3920 to 0 to terminate

parameter setting.

When there are servo axes for interpolation with the Cs contouring

axis, the parameters must be set according to the procedure below for

each axis.

(1) Set the number of a servo axis (1 to 4) for interpolation with the

Cs contouring axis in parameters 39n0 (n = 0, 1, and 2).

(2) Set loop gain values of the servo axis specified in (1) above

which is used when the Cs contouring axis is controlled in

parameters 39n1, 39n2, 39n3, and 39n4. (There are four stages

for main gears used.)

(3) When the number of specified servo axes is less than 3, set the

remaining parameters (39n0) to 0 to terminate parameter setting.

When the number of a Cs contouring axis is set to parameter 39n0, the

parameter is assumed to be set to 0.

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 axes are used (bit 7 (CSS) of parameter No. 3704 = 1),

these parameters are shared.
