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.
For details on the "OPR control", refer to OPR CONTROL (

Page 316, CHAPTER 8). For details on each setting
item, refer to List of Parameters (

Page 316, CHAPTER 8).

.
R: Set when using the OPR retry function. (

Page 510, Section 12.2.1)
S: Set when using the OP shift function. (

Page 515, Section 12.2.2)
C: Set the deviation counter clear signal output time.
*1 This is an irrelevant item, so the set value will be ignored. If the value is the default value or within the setting range,
there is no problem.
(1) Checking the OPR parameters.
[Pr.43] to [Pr.57] are checked with the following timings.
• When the "PLC READY signal [Y0]" output from the CPU module to the LD75 changes from OFF to ON
• When the test operation button is turned ON in the test function using GX Works2
