For the last enabled point number, set Running Motion = “single”.
If Dwell Time = 0, the acceleration/deceleration setting of the first point number that is selected upon CW start
PCSTART1 ON will be applied, and the settings of subsequent point numbers will be discarded.
This procedure executes a series of positioning motion
following
the point numbers
in
order
. Motion instructions per point numbers are executed with no interruptions and the
rotational speed changes continuously. Positioning motion will continue up to (not including)
the point number whose Running Motion is “single”.
Set Running Motion of all enabled point numbers to “continuous”, and specify the first point
number for turning on CW drive signal PCSTART1.
For this motion group, set Dwell Time = 1 ms .
