With memory operation, the positioning sequences describing the operating
patterns have to be transferred to the Position Control Unit. In contrast, with
direct operation, position control can be carried out by simply writing the posi-
tions and speeds each time to the designated area (the operating data area) in
the Programmable Controller. As a result, the positions and speeds can be input
from outside and processed by calculating present positions from the Position
Control Unit, for example, and position control executed with the data as if it were
new data. This fact allows more flexibility, and permits position control to be
exercised more simply.
