- 858 -
Set the direction of reference position return using CSO (bit 3 of
parameter No. 3000).
- Stopping reference position return
(i) For manual operation
When the reset, emergency stop, or feed axis and direction
selection signal is set to "0," reference position return is
stopped. Use STJ (bit 2 of parameter No. 5821) to specify
whether reference position return is to be stopped by setting
the feed axis and direction selection signal to "0." After
stopping reference position return, perform reference
position return again from the first step, if required.
(ii) For automatic operation
Reference position return can be stopped by a reset,
emergency stop, or feed hold. In any case, after stopping
reference position return, perform reference position return
again from the first step, if required.
Operating the Cs contour control axis (automatic/manual)
After reference position return after switching to Cs contour control
mode, the axis can be operated in the same way as normal servo axes.
In the spindle rotation control mode, no commands for Cs contour
control axes can be accepted. During automatic operation, alarm
PS0571 or PS0572 occurs.
Perform manual operation for a Cs contour control axis so that it is not
performed in spindle rotation mode by the PMC ladder.

[Classification] Input signal
[Function] These signals are used to switch between spindle rotation control mode
and Cs contour control mode.
These signals are provided for axes on a one-to-one correspondence. A
number appended to a signal name represents a controlled axis number.
Use the signal with the controlled axis number of a Cs contour control
axis.
SCNTRx : x
:1 ... Cs contour control mode switching signal for the first axis
2 ... Cs contour control mode switching signal for the second axis
3 ... Cs contour control mode switching signal for the third axis
[Operation] When this signal is set to "0," spindle rotation mode is set. When it is
set to "1," Cs contour control mode is set. Before switching from Cs
contour control mode to spindle rotation control mode, confirm that the
move command for the spindle has terminated completely. The spindle
can be switched from spindle rotation control mode to Cs contour
control mode while it is rotating.
