3.8.2. Power Wiring for the Regenerative Drive - Size S74
Two drive arms per phase are required when connecting an “S74” regenerative drive.
The diagram below shows how to connect the interface panels (supplied by Elettronica Santerno). It also
shows how to connect the electromechanical components allowing matching the output terminal commutated
voltage with the mains sinusoidal voltage, and filtering the current component at the drive commutation
frequency.
The following is a list of the additional components and the matching tables between those components and
the regenerative drive:
Two regenerative reactors (see sections 3.9.8, 3.9.9, 3.9.10);
One filter reactor (see sections 3.9.11, 3.9.12, 3.9.13);
Two interface panels (see sections 3.9.17, 3.9.18, 3.9.19);
Two bypass contactors.
