Built-in digital FLL speed control logic. (1) Control (ⅰ)Register Control ■ at speed control = OFF The PWM drive is executed by the PWM duty ratio, the PWM direction and the PWM ON/OFF which are controlled by the register settings. ■ at speed control = ON The speed control drive is executed by the target speed value, the direction, the coefficient value of PI filter and the turning ON/OFF which are controlled by the register settings. The motor speed is adjusted by comparing the target speed with the motor speed detected at the signal of photo-interrupter. (ⅱ)External Pin Control (only at speed control = OFF) ■ at speed control = OFF The PWM drive is executed by the PWM duty ratio which is controlled by the register setting. The PWM direction and the PWM ON/OFF are controlled by IN5A/IN5B pin. SIF H.B.
