5DATA USED FOR POSITIONING CONTROL

5.1.2 Setting items for positioning parameters

MELSEC-Q

The table below lists items set to the positioning parameters. Setting of positioning parameters is similarly done for individual axes for all controls achieved by the QD75. For details of controls, refer to Section 2. For details of setting items, refer to Section 5.2 "List of parameters".

: Always set

: Set as required (Read "–" when not required.)

: Setting not possible

:Setting restricted

–: 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.)
