3.3.2 Saddle section
[A] Stacker motor drive circuit
The stacker motor drive circuit controls the rotation and stoppage, rotational direction and motor current
of the stacker motor.
The stacker motor is driven by pulse signals (MOT3-OUT1A, MOT3-OUT1B, MOT3-OUT2A and
MOT3-OUT2B) output from the motor driver (IC17) under the command of a clock signal (TMO2), a
rotational direction signal (MOT3-DIR) and a current setting signal (MOT9-CUR0) from the CPU of the
saddle control PC board, and thus this motor shifts the stacker stapling position and folding position.
