6 POSITIONING CONTROL
6.2 1 Axis Linear Positioning Control
Positioning control from the current stop position to the fixed position for specified axis
is executed.
Positioning is controlled using ABS-1 (Absolute data method) or INC-1 (Incremental
data method) servo instructions.

[Control details]
Control using ABS-1 (Absolute data method)
(1) Positioning control from the current stop address (pre-positioning address) based
on the home position to the specified address is executed.
(2) The travel direction is set by the current stop address and the specified address.
When the current stop address is 1000, and the specified address is 8000.
