remaining Cs contour control axes is set automatically for
the other Cs contour control axes and servo axes.
3 Switching between spindle speed control and Cs contour
control during automatic operation
Switching is impossible during automatic operation and
during axis movement.
If switching from spindle speed control to Cs contour
control or vice versa is made in the middle of a block
executed in automatic operation, position gains do not
change immediately; they are set automatically after all
controlled axes are stopped completely.
4 Similarly, when switching between spindle speed control
and Cs contour control is made in other than automatic
operation, automatic setting is performed after the
completely stopped states of all controlled axes are
confirmed
- Reference Position Return of Cs Contour Control Axis
After the serial spindle is switched from spindle speed control to Cs
contour control mode, the current position is undefined. Return the
spindle to the reference position.
The reference position return of the Cs contour control axis is as
follows:
•
In manual mode
After the serial spindle enters the Cs contour control mode, move
the spindle in the direction of the reference position by turning
on the feed axis and direction select signal (+Jn (G100) or -Jn
(G102)). The spindle starts the movement to the reference
position; when it reaches that position, the reference position
return completion signal ZPn <F094> turns to "1".
Turning any feed axis and direction select signal to "1" moves
the tool in the reference position direction.
•
In the automatic mode
(i) G00 command
If a serial spindle is placed in the Cs contour control mode,
then the G00 command is issued without performing
reference position return even once when bit 7 (NRF) of
parameter No. 1814 is 0, the serial spindle performs a
reference position return.
As G00 is specified, the serial spindle indexes the reference
position, then performs positioning at a specified position.
Only when positioning at the reference position is
performed, the reference position return completion signal
ZPn <F094> is set to 1 after completion of the positioning
operation.
When a reference position return has been performed at
least once, a G00 command performs a normal positioning
operation.
When a reference position return is performed manually or
by using G28, the spindle is always positioned at the
reference position; on the other hand, when a reference
