2 phase excitation/1-2 phase excitation can be selected by the excitation mode setting signal (MODE).
(On this document feeder, the feed and reversal motors are fixed to 1-2 phase excitation, and the trans-
port motor is fixed to 2 phase excitation.) The rotating speed of the motor and direction of rotation can be
controlled by the drive clock signal (CLOCK) and rotation direction signal (CWB). When the reset signal
(RESETB) turns Low, all outputs of the drive IC are turned OFF regardless of the state of other signals.
The motor current value can be set by inputting the analog voltage to the current setting terminal (Vref).

When the CPU output port is Low level, Q12 turns ON to actuate the solenoid. The solenoid drive signal
is a PWM signal. When the solenoid starts to actuate, the solenoid actuates at its maximum torque at
100% duty After actuation is completed, the duty ratio is reduced to hold actuation while heating of the
solenoid is held in check.
