4.3.6 AFE Unit
The active front end (AFE) is an optional unit used to feed the energy generated by
the motor during braking back to the power grid. This eliminates the needs of the
braking unit and braking resistor and reduces heat emission. Inovance AFE features
energy efficiency, low noise, low harmonic, and high power factor.
