D-Vo Light – Marelli Motori
Still under actual operating conditions, starting from 0rpm to reach the rated
speed, the voltage rise ramp may fail to be perfectly linear, with a slight overshoot
at low frequencies and voltages (never reaching a significant value anyway).

Voltage reference
Voltage Matching D-Vo provides the Voltage Matching function, whose purpose is adapting the D-
Vo voltage setpoint to match the grid voltage, immediately before the
synchronisation with the grid is performed.
This operation can be activated through a command from the VMATCH digital
input, and is only performed if the grid voltage remains within a range of generator
voltage values, defined by the parameters Minimum Limit and Maximum Limit,
which can be set through D-Vo Dashboard (Paragraph 7.3.4).
