Motor drive control device which uses pulse width modulation to control the speed of a motor |
摘要 |
A motor drive control device which drives a motor in accordance with a pulse width modulated input signal, a first binary signal indicating a rotation direction for driving the motor and a second binary signal indicating whether drive of the motor is ON or OFF. The motor drive control device includes a logic circuit receiving the pulse width modulated input signal, the first binary signal and the second binary signal and, in response, producing a first pulse width modulated output signal and a second pulse width modulated output signal which together indicate a rotation direction and rotation speed for driving the motor.
