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):
