Individual positioning control and continuous positioning control
The QD75 performs positioning according to the user-set positioning data, which is a
set of information comprised of the control method (position control, speed control,
speed-position switching control), positioning address, operation pattern, and so on.
Up to 600 of positioning data are assigned respectively to positioning data Nos. 1 to
600 per axis and registered to the QD75MH.
The operation pattern set in each positioning data by the user determines whether to
perform positioning operation with one positioning data item or to perform continuous
positioning operation with multiple positioning data items.

complete)
The operation completed upon completion of positioning for the specified
