[Control Details]
Control with ABS-1 (absolute data method)
(1) Positioning control from the current stop address (pre-positioning address) to
the designated address, using the home position as the reference.
(2) The travel direction is determined from the current stop address and the
designated address.
The travel direction is shown below if the current stop address is 1000, and the
designated address is 8000.
