Set the output switching Frequency (PWM frequency):
On SOLO you can have any switching frequency from 8kHz to 80kHz at the output depending
on your need and the inductance of your motor, in general the Motors with low inductance need
higher switching frequencies to be able to keep their current stabilized and controlled.
_NOTE: By default there are two types of PWM frequencies available on SOLO before you
overwrite them, 20kHz and 80kHz (check the User Manual of the device to learn more), but if
you overwrite the PWM frequency by using the following method, the switching frequency for
all the motor types becomes the selected value as long as you haven’t done the “Reset factory”
which will set back everything to default mode.
Set switching frequency on 30Khz

To check the written value:
Read the switching frequency:
FF FF 00 8B 00 00 00 00 00 FE
Reset the Device to Factory Mode:
This is a packet to reset the device into factory default mode; after this action, all the parameters
saved in the memory will be reset into their default values. After this action, a power recycle is
required so that the changes can take effect.
