- 856 -
Command address
Any address can be selected for a Cs contour control move command.
The value set for parameter No. 1020 is used as the axis name.
Switching between spindle rotation control and Cs contour control
- Switching from the spindle rotation control mode to the Cs
contour control mode
Set DI signal SCNTR1, SCNTR2, SCNTR3, ... <G067#7, G071#7,
G075#7, ...> to "1" to switch the serial spindle to Cs contour
control mode.
When switching to Cs contour control is executed during spindle
rotation, the spindle immediately stops and switching is executed.
- Switching from Cs contour control mode to spindle rotation
control mode
Set DI signal SCNTR1, SCNTR2, SCNTR3, ... <G067#7, G071#7,
G075#7, ...> to "0" to switch the serial spindle to spindle rotation
control mode.
Confirm that the move commands for spindles during both
automatic and manual operation completely terminate, then
execute switching. If switching is executed while the spindle is
rotating, an alarm indicating the interlock state or excess
positional deviation occurs.
- Automatic position gain setting at switching between spindle
rotation control and Cs contour control
1. Switching from spindle rotation control to Cs contour
control
If different position gains are set for the Cs contour control
axis and other servo axes at control switching, linear or
circular interpolation with the Cs contour control axis is not
performed normally.
For this reason, the position gain (parameter No. 3069, 3070,
3071, or 3072) selected by the clutch/gear signal (CTH1A,
CTH2A) is automatically set for servo axes other than the Cs
contour control axis.
When there are two or more Cs contour control axes, the
minimum value among the selected position gains is
automatically set for other Cs contour control axes and servo
axes.
2. Switching from Cs contour control to spindle rotation
control
The original position gain (parameter No. 1825) is
automatically set for the servo axes.
When there are two or more Cs contour control axes and
these axes continue to be used as Cs contour control axes, the
minimum value among the position gains selected for
remaining Cs contour control axes is automatically set for
other Cs contour control axes and servo axes.
3. Switching between spindle rotation control and Cs contour
control during automatic operation
During automatic operation, switching cannot be performed
while the tool is moving along an axis.
