Always set

Set as required ("–" when not set)

Setting not required (This is an irrelevant item, so the setting value will be ignored. If the value is the default value or within the setting range, there is no problem.)

Checking the positioning parameters

Pr.1

to

Pr.42

are checked with the following timing.

(1)When the "PLC READY signal [Y0]" output from the PLC CPU to the QD75 changes from OFF to ON

(2)When the test operation button is turned ON in the test mode using GX Configurator-QP

(3)When an error check is carried out with GX Configurator-QP

REMARK

•"High-level positioning control" is carried out in combination with the "major positioning control".

Refer to the "major positioning control" parameter settings for details on the parameters required for "high-level positioning control".
