[E] Stack transport motor drive circuit
The stack transport motor drive circuit controls the rotation and stoppage, rotational direction and motor
current of the stack transport motor.
The stack transport motor is driven by pulse signals (MOT8-OUT1A, MOT8-OUT1B, MOT8-OUT2A
and MT8-OUT2B) output from the motor driver (IC38) under the command of a clock signal (TIOCA3),
a rotational direction signal (MOT8-DIR) and current setting signals (MOT8-CUR1 and MOT8-CUR0)
from the CPU of the finisher control PC board, and thus this motor rotates the stack transport belt.
