Figure 4-1 shows both the power and control connections for the standard
regen solution this being a single regen and single motoring drive system.
For this solution the Vac supply is temporarily connected to the Regen
drive's L1, L2, L3 inputs for initial power-up only, removing the need for
an external charging circuit. The main AC supply to L1, L2, L3 on the
Regen drive (K3) is interlocked with the Regen drive's enable preventing
operation when the charging circuit is still connected.
NOTE
The regen inductor duty is very arduous and therefore selection is critical
as a result only Regen inductors specified in this guide should be used.
