1–5–1 Open-loop System
In an open-loop system, the Position Control Unit outputs pulse trains as
specified by the PC program to control the angle of rotation of the motor. Be-
cause the Unit outputs pulse trains, it is generally used with a stepping motor.
The angle of rotation of a stepping motor can be controlled through the num-
ber of pulse signals supplied to the motor driver. The number of rotations of
the stepping motor is proportional to the number of pulses supplied by the
Unit, and the rotational speed of the stepping motor is proportional to the fre-
quency of the pulse train.
