Active Infeed Closed-Loop Control Chassis - Siemens SINAMICS S120 Function Manual

Note
When a Wideband Line Filter is connected, it must be parameterized with p0220 = 1...5. The
temperature sensor must be connected to terminal X21 of the Active Line Module.
The DC link voltage (p3510) can be set within the following limits:
● Upper limit:
– Maximum DC link voltage (p0280)
– Product of line voltage (p0210) and max. step-up factor (r3508)
● Lower limit: Supply voltage (p0210) multiplied by 1.42

Active Infeed closed-loop control chassis

Overview
The following figure gives an overview of the structure of an Active Line Module. In addition, the
figure shows the differences between the Chassis and Chassis-2 designs.
Figure 3-2
Operating mode of the Active Infeed Control for Active Line Modules of the Chassis format
Active Line Modules of the Chassis format (ALM Chassis) work exclusively in Active Mode.
In the Active Mode, the DC link voltage is regulated to a variable setpoint (p3510) which results
in a sinusoidal line current (cos φ = 1).
