NOTE
Overvoltage
Please note that during a braking process a voltage is generated by the motor and
fed back.
If the generated energy cannot be absorbed by the voltage source, the voltage
level in the system increases and can, in the worst case, generate an overvoltage
which damages or destroys the controller.
Therefore, when operating with a power supply unit, it is essential to integrate a
sufficiently dimensioned capacitor bank in the supply lines that can absorb the
excess energy.
