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.
