Example: for V
Exc_Rated
=32 Vdc, the excitation voltage must be at least 55 Vac. However, values much higher than that may worsen the
dynamic response.

The auxiliary DC input for excitation allows a machine without enough remanent voltage to be controlled when the power supply comes
from the machine terminals. The origin source must be galvanically isolated from the power supply.
