5. INSTALLATION (HARDWARE)

5.1 Connecting Driver to a DC Motor

URC10 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.

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)
