adjustable parameters

Parameter

adjustable Values Description

Actual / Rated Power

Actual or Rated can be selected

Start frequency

50.00 ... 55.00

The frequency when the power reduction starts

Stop frequency

Stop frequency means the frequency when

power = 0. This value is calculated by the gra-

dient and the start frequency.

Recovery frequency

50.00 ... 55.00

This feature is only for MVD. This value is

equal to the frequency of the grid connection.

Gradient

0 ... 100 %

This feature adjusts the gradient. The units are

% / Hz.

Recovery Time

Not applicable for LVD or MVD
