[B] Side alignment motor drive circuit
The side alignment motor drive circuit controls the rotation and stoppage, rotational direction and motor
current of the side alignment motor.
The side alignment motor is driven by pulse signals (MOT4-OUT1A, MOT4-OUT1B, MOT4-OUT2A and
MOT4-OUT2B) output from the motor driver (IC11) under the command of a clock signal (TMO3), a
rotational direction signal (MOT4-DIR) and a current setting signal (MOT4-CUR0) from the CPU of the
saddle control PC board, and thus this motor opens or closes the jog.
