5.1.3 Setting items for zero point return parameters
When carrying out "zero point return control", the "zero point return parameters" must
be set. The setting items for the "zero point return parameters" are shown below.
The "zero point return parameters" are set commonly for each axis.
Refer to "Chapter 8 ZERO POINT RETURN CONTROL" for details on the "zero point
return control", and to section "5.2 List of parameters" for details on each setting item.

used.
: Always 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.)
R : Set when using the section "12.2.1 Zero point return retry function". ("–" when not set.)
S : Set when using the section "12.2.2 Zero point shift function". ("–" when not set.)
Checking the zero point return parameters.
Pr.45 to Pr.58 are checked with the following timing.
(1) When the "PLC READY signal" output from the PLC CPU to the AD75
changes from OFF to ON
(2) When the test mode using the AD75 software package
