Absolute positioning
Positioning operation is performed from the present position to the set target position. In the Target position (607Ah),
set the target position on the coordinates with the home as a reference.
Example: When moving from the command position "1,000" to the target position "4,000"
Set 4,000 steps in the Target position (607Ah) to start absolute positioning operation.

z
Incremental positioning (based on command position)
Positioning operation with the set travel amount is performed from the present command position. In the Target
position (607Ah), set the travel amount from the present command position to the target position.
Example: When moving from the command position "1,000" to the target position "4,000"
Set 3,000 steps in the Target position (607Ah) to start incremental positioning (based on command position)
operation.

z
Incremental positioning (based on actual position)
Positioning operation with the set travel amount is performed from the present actual position. In the Target position
(607Ah), set the travel amount from the present actual position.
Example: When moving 3,000 steps from the command position "1,000" and the actual position "900"
Set 3,000 steps in the Target position (607Ah) to start incremental positioning (based on actual position) operation. The command
position and the actual position after completing the operation will be "3,900."

•
The reference position of the operation based on the actual position varies depending on a load.
•
If the command position and the actual position are different such as push-motion operation, the
next operation can be started based on the actual position of the push position or the like.
