CL Setting range Description
[Default]
Notes
The power factor setpoint may be adjusted between 0.71 leading and 0.71
lagging.
Selecting a different data source may cause the controller to not operate
properly.
0 -0.999 to +1.000 The desired power factor may be configured here so that the reactive power
is regulated in the system.
[+1.000]
The designations "–" and "+" stand for inductive/lagging (generator overex‐
cited) and capacitive/leading (generator underexcited) reactive power. This
setpoint is active only in mains parallel operation.

2 0.01 to 100.00 The different setpoint values are supplied to the controller via this ramp.
%/s
The slope of the ramp is used to alter the rate at which the controller modifies
[3.00 %/s] the setpoint value. The faster the change in the setpoint is to be carried out,
the greater the value entered here must be.
Notes
This ramp is also used in isolated operation for loading or unloading an addi‐
tional genset. An excessive oscillation may occur if the ramp is configured too
high.
The Power Factor Characteristic function is adapting the reactive
power flow between generator and mains to support a dynamic
stabilization of the mains. Some network provider prefer therefore
a power factor control over real power PF(P) and other provider
prefer power factor control over mains voltage Q(V). Both methods
are configurable alternatively.
A method to support the mains is to feed different reactive power
values into the grid in relation to the own active power value. The
reactive power is defined through a power factor setpoint for the
generator. This can be defined in characteristic curve.
