Setting item
[Cd.43] Simultaneous starting axis
[Cd.45] Speed-position switching
device selection
[Cd.46] Speed-position switching
command
[Cd.100] Servo OFF command

Set the number of simultaneous starting axes and target axis.
When "2" is set to the number of simultaneous starting axes, set the target axis
No. to the simultaneous starting axis No. 1.
When "3" is set to the number of simultaneous starting axes, set the target axis
No. to the simultaneous starting axis No.1 and 2.
When "4" is set to the number of simultaneous starting axes, set the target axis
No. to the simultaneous starting axis No.1 to 3.

When the same axis No. or axis No. of own axis is set to the multiple
simultaneous starting axis No, or the value outside the range is set to the number
of simultaneous starting axes, the error "Error before simultaneous start" (error
code: 501) occurs, and the operation is not executed.
Note) Do not set the simultaneous starting axis No.2 and 3 for 2-axis interpolation,
and do not set the simultaneous starting axis No.3 for 3-axis interpolation.
The setting value is ignored.
Fetch cycle: At start

Select the device used for speed-position switching.
Note) If the setting is outside the range at start, operation is performed with the
setting regarded as "0".
Fetch cycle: At positioning start for speed-position switching control/position-speed
switching control

Speed-position control switching is performed when "2" is set in "[Cd.45] Speed-
position switching device selection". Other than setting value is ignored.
Note) This parameter is made valid only when "2" is set in "[Cd.45] Speed-position
switching device selection" at start.
