A reactive current setpoint can be set to compensate the reactive current or to stabilize the
line voltage in infeed mode. The total setpoint is the sum of the fixed setpoint p3610 and the
dynamic setpoint via the connector input p3611.
● The direction of rotation of the line supply is compensated automatically with reactive
current control.
– A negative reactive current setpoint causes an inductive reactive current (overexcited
operation).
– A positive reactive current setpoint generates a capacitive reactive current
(underexcited operation).
● The closed-loop control limits the reactive current setpoint dynamically in such a way that
the sum of the active current setpoint and the reactive current setpoint does not exceed
the maximum device current.
● The reactive current demand of a line filter selected in the configuration wizard is
automatically supplied by the Active Infeed Module. This means that the display value of
the current reactive current setpoint in r0075 no longer corresponds with the
parameterized total reactive current setpoint.
● The reactive power setpoint of the Active Infeed Module with respect to the line supply
can be obtained by multiplying the parameterized total reactive current setpoint by
1.73 rated line voltage.
