Setting PI Mode
Over the hall sensors built in the motor the speed is measured and is supplied to the drive logic.
Dependent on the difference between measured actual speed and by the electronic given target
speed the modulation is affected.

the control mode can be adapted to the size of impeller. For heavy fan
impellers it can come with to fast rampup to overcurrent messages.
