4 DATA USED FOR POSITIONING CONTROL
4.1.2 Setting items for parameters
The table below lists items set to the positioning parameters. Setting of parameters is
similarly done for individual axes for all controls achieved by the QD70.
For details of controls, refer to SECTION 2 "CONTROL DETAILS AND SETTING". For
details of setting items, refer to "4.2 List of parameters".

: Always set
: Set as required (Read "–" when not required.)
– : Setting not required. (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.)
Checking the parameters
Pr. 1 to Pr. 10 are checked for the setting ranges when the "PLC READY signal
(Y0)" output from the PLC CPU to the QD70 changes from OFF to ON. At this time,
an error occurs in the parameter whose value has been set outside the setting
range. (For details, refer to "CHAPTER 13 TROUBLESHOOTING".)
