5.1.3 Setting items for OPR parameters
When carrying out "OPR control", the "OPR parameters" must be set. The setting
items for the "OPR parameters" are shown below.
The "OPR parameters" are set commonly for each axis.
Refer to Chapter 8 "OPR control" for details on the "OPR control", and refer to Section
5.2 "List of parameters" for details on each setting item.

are checked with the following timing.
•
When the "PLC READY signal [Y0]" output from the PLC CPU to the QD77MS
changes from OFF to ON.
•
When the positioning test of GX Works2 is executed.
