5.1.3 Setting items for OPR parameters
When carrying out "OPR control", the "OPR par ameters" must be set. The setting
items for the "OPR parameters" are shown bel ow.
The "OPR parameters" are set commonly for e ach axis.
Refer to Chapter 8 "OPR control" for details on the "OPR co n tro l", and to Section 5.2
"List of parameters" for details on each sett ing item.

: Always set
: Preset parameters are used for machine OPR control.
– : 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.)
R : Set when using the "12.2.1 OPR retry function". ("–" when not set.)
S : Set when using the "12.2.2 OP shift function". ("–" when not set.)
C : Set the deviation counter clear signal output time. (Read as "–" when the setting is not required.)
Checking the OPR parameters.
Pr.43 to Pr.57 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
