[Default]
1 0.1 to 10.0 The gain factor K
[5.0]
By increasing the number configured in this parameter, the operating time of
the relay will be in-creased in response to a deviation from the frequency ref‐
erence.
By increasing the gain, the response is increased to permit larger corrections
to the variable to be controlled. The farther out of tolerance the process is the
larger the response action is to return the process to the tolerance band.
Notes
If the gain is configured too high, the result is excessive overshoot/undershoot
of the desired value.
This parameter is only visible if frequency control (parameter
is configured to "3pos controller".

Notes
This parameter is only visible if frequency control (parameter

1 1.0 to 9.9 s The measured generator frequency must be within the deadband range for
the time configured here in order to multiply the deadband with the factor con‐
