5 DATA USED FOR POSITIONING CONTROL
(2) Incremental (INC) system, fixed-feed 1, fixed-feed 2, fixed-feed 3,
fixed-feed 4
•
The setting value (movement amount) for the INC system is set as a
movement amount with sign.
When movement amount is positive: Moves in the positive direction (address
increment direction)
When movement amount is negative: Moves in the negative direction (address
decrement direction)

The table below lists the control systems that require the setting of the positioning
address or movement amount and the associated setting ranges.
(With any control system excluded from the table below, neither the positioning
address nor the movement amount needs to be set.)
