Specify G28 after the spindle enters the Cs contour control mode, and the spindle moves to
the intermediate point and then return to the reference position.
ZPn (F094) becomes 1 after the reference position return is executed.
The operation of Cs contour control axis
(Manual/Automatic)
If the Cs contour control axis has been returned to the reference position, the operation of Cs
axis is same as the common NC axis.
In the spindle speed control, the Cs contour control axis can not be performed. Otherwise, the
system alarms.
So, in the spindle speed control mode, it is not permitted the manual operation of Cs by the
PLC ladder diagram.
The signal shift of spindle contour control
CON (G027#7)
[Type] Signal input
[Function] This signal is used for shifting between spindle speed control mode and
Cs contour control mode.
When this signal is set to 1, the spindle is shifted to the Cs contour control mode from
speed control mode.
When this signal is set to 0, the Cs contour control mode comes back to the speed
control mode.
