Setting chopping frequency of the constant current of the motor

Formula of setting chopping frequency

fOSCM = 1 / [0.56 x

｛

C x (R1 + 500)}]

fchop = fOSCM / 16

Recommended frequency range:
fchop=40kHz to 150kHz
100kHz configuration
Mounted parts are as follows;
Capacitor (C=270pF), Resistance
(R1=3.6kΩ)

Waveform of motor current

Chopping frequency (fchop)
