6. GETTING STARTED

Hat-MDD10 is compatible with 2 types of PWM operation, which are:

1. Sign-Magnitude PWM – For sign-magnitude PWM operation, 2 control signals are used to

control the speed and direction of the motor. PWM is feed to the PWM pin to control the

speed while DIR pin is used to control the direction of the motor.

2. Locked-Antiphase PWM – For locked-antiphase PWM operation, only 1 control signal is

needed to control the speed and direction of the motor. PWM pin is connected to logic high

while the DIR pin is being feed with the PWM signal. When the PWM signal has 50% duty

cycle, the motor stops running. If the PWM has less than 50% duty cycle, the motor will turn

CW (or CCW depending on the connection). If the PWM signal has more than 50% duty

cycle, motor will turn CCW (or CW depending on the connection).

Sample connection diagram is as follow:
