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

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.

●Smart Mode

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.

The DC link voltage setpoint (p3510) and the control type are preset as follows during commissioning in line with the connection voltage (p0210):
