: 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

"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".
