differ according to the

Major positioning control sub functions

Refer to Section 3.2.4 "Combination of QD75 major functions and sub functions" for details on "sub functions" that can be combined with the major positioning control.

Also refer to Chapter 12 "Control sub Functions" for details on each sub function.

Major positioning control from peripheral devices

"Major positioning control" can be executed from the peripheral device test mode. Refer to GX Configurator-QP Operating Manual for details on carrying out major positioning control from the peripheral device.

REMARK

600 positioning data (positioning data No. 1 to 600) items can be set per axis.
