2 0.00 to 0.50 Hz This value is the offset for the synchronization to the busbar/utility.
[0.10 Hz] With this offset, the unit synchronizes with a positive slip.
Example
If this parameter is configured to 0.10 Hz and the busbar/mains frequency is
50.00 Hz, the synchronization setpoint is 50.10 Hz.
2 1 to 99 The phase matching gain multiplies the setting of the proportional gain
(parameter
[5]
2 0.02 to 0.25 Hz Phase matching will only be enabled if the frequency difference between the
systems to be synchronized is below the configured value.
[0.05 Hz]
2 0.0 to 100.0 % The value entered for this parameter is the start reference point for the analog
output to the speed controller.
[50.0 %]
Notes
If the output to the speed control has been disabled, the output will act as a
control position reference point.
CL Setting range Description
[Default]
2 [PID analog] The generator load is controlled using an analog PID controller.
3pos controller The generator load is controlled using a three-step controller.
Off Load control is not carried out.
2 0.01 to 100.00 The proportional coefficient specifies the gain. By increasing the gain, the
response is increased to permit larger corrections to the variable to be con‐
[1.00]
trolled.
The farther out of tolerance the process is the larger the response action is to
return the process to the tolerance band.

Rated power: 500 kW
Rated frequency setpoint: 50.0 Hz
Droop 5.0 %
Active power: 0 kW = 0 % of rated power
Frequency is adjusted to: (50.0 Hz – [5.0 % * 0.0 * 50 Hz]) = 50.0 Hz.
Active power: +250 kW = +50 % of rated power
Frequency is adjusted to: (50.0Hz – [5 % * 0.50 * 50 Hz]) = 50.0 Hz –
1.25 Hz = 48.75 Hz.
Active power: +500 kW = +100 % of rated power
Frequency is adjusted to: (50.0Hz – [5 % * 1.00 * 50 Hz]) = 50.0 Hz –
2.5 Hz = 47.50 Hz.
