<Setting method>
First, select servo axes which perform interpolation with the Cs
contouring axis. (Up to five axes can be selected.)
When there is no servo axis for interpolation with the Cs contouring axis,
set the parameters 3900, 3910, 3920, 3930, and 3940 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 8) for interpolation with the Cs
contouring axis in parameters 39n0 (n = 0, 1, 2, 3, and 4).
(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 5, 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
The loop gain used for Cs contouring control is selected
when the mode changes from the spindle mode to the Cs
contouring axis control mode according to the gears set at
this time.
If gears are switched in the Cs contouring axis control mode,
the loop gain cannot be changed.
