5. TRAY, CHANGE MOTOR DRIVE PART
Rotational direction control
The forward and reverse rotational direction is controlled by FWD (pin 10) and REV (pin 11) inputs.
Conditions are as follows.
Motor speed control
— The motor speed is proportional to the difference voltage between the pin17 (DO4+) and the pin16 (DO4
).
— By applying the voltage to the pin9 of CTL, the motor speed can be controlled and it is linearly proportional
to the applied control voltage.
— When both VM3, 4 and V
CC
are 5V, and the applied control voltage is higher than 4V, the motor speed is
not proportional to the control voltage but the motor speed becomes constant.
— If the pin9 is opened, the motor torque becomes maximum.
— The maximum output swing is 3.8V, when VM3, 4 and V
CC
are 5V.
