Input power supply pin for motor drive ; connect a low impedance capacitor with a recommended

capacitance of 100

µF/35V.

Output pin for motor drive (ch3) ; connect a low impedance capacitor with a recommended

capacitance of 470

µF / 35V.

Output pin for motor drive (ch2) ; connect a low impedance capacitor with a recommended

capacitance of 470

µF / 35V.

Power supply pin

Output voltage control pin (ch3) ; PWM signal or DC signal is inputted. The output voltage can be

changed either by changing the duty of PWM signal or by changing the DC voltage value.

Output voltage control pin (ch2) ; PWM signal or DC signal is inputted. The output voltage can be

changed either by changing the duty of PWM signal or by changing the DC voltage value.

Output voltage control pin (ch1) ; PWM signal or DC signal is inputted. The output voltage can be

changed either by changing the duty of PWM signal or by changing the DC voltage value.

Output pin for motor drive (ch1) ; connect a low impedance capacitor with a recommended

capacitance of 470

µF / 35V.
