9.7 Cs CONTOUR CONTROL
General
A spindle motor controlled by the spindle serial output function is
called a serial spindle.
For a serial spindle, positioning and interpolation with other servo axes
can be performed. In other words, linear interpolation, circular
interpolation, and so forth can be specified between the spindle and
servo axis.
Cs contour control can be applied simultaneously to up to four
spindles.
Limitation
- Increment system
Use the IS-B setting for the least input increment.
- Command multiplication
Set 2 (one time) for the command multiplication.
- Reference position return
Specify that the workpiece coordinate system is always preset at
manual reference position return.
Explanation
For a serial spindle, positioning and interpolation between another
servo axis and Cs contour control axis can be performed. In other
words, linear interpolation, circular interpolation, and so forth can be
specified between a Cs contour control axis and servo axis and between
Cs contour control axes.
Rotating a serial spindle with a velocity command is referred to as
spindle rotation control. Controlling the position of a spindle with a
move command is referred to as Cs contour control.
Switching between spindle rotation control and Cs contour control is
performed by the DI signal from the PMC.
Manual and automatic operation for Cs contour control axes are
performed in Cs contour control mode in the same way as for normal
servo axes.
(For an explanation of reference position return operation, see the
explanation of reference position return in this section.)
Setting a Cs contour control axis
Place a Cs contour control axis as one of CNC controlled axes. Any
controlled axis can be selected as a Cs contour control axis.
Set the following parameters for a Cs contour control axis:
1 Servo axis number (set parameter No. 1023 to "0.")
2 Spindle number (parameter No. 1028)
3 Rotation axis setting (set ROT, bit 0 of parameter No. 1006, to "1.")
4 Setting a Cs contour control axis (set CNT, bit 7 of parameter No.
1804, to "1.")
Parameters 1 and 2 can be set by FSSB automatic setting.
