The Fig. 10 shows the energy flow when the elevator absorbs energy. The ERS 2G will
automatically detect this situation and it will inject the energy elevator requires, as
shown in Fig. 10.a. If the ERS 2G is not capable to provide all the required energy
(because the energy accumulator is depleted or because it does not reach the
required power), the drive will absorb further energy in a conventional way from the
three-phase mains (Fig. 10.b).
