Active Infeed closed-loop control for Active Line Modules booksize
The Active Line Module can be operated in two different modes depending on the
parameterized line supply voltage (p0210):
● Active Mode
● Smart Mode
The DC link voltage setpoint (p3510) and the control type are preset as follows during
commissioning in line with the connection voltage (p0210):

Schematic structure of Active Infeed booksize
In Active Mode, the DC link voltage is regulated to a variable setpoint (p3510), which
results in a sinusoidal line current (cosφ = 1). The level of the reactive current is also
controlled and can be specifically defined.
Energy recovery capability is maintained in Smart Mode, although there is a lower DC link
voltage in comparison to the Active Mode. The DC link voltage is dependent on the
current line voltage.
