 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".
