Active Line Module
The self-managed infeed/regenerative unit with booth converter creates an increased
controlled DC link voltage. This makes the connected Motor Modules independent of
tolerances in the energy supply system.
The Control Unit is used to control, trigger and monitor the Active Line Module. The data
exchange is performed using DRIVE-CLiQ.
Control types:
The Active Line Module operates in two different control types depending on the
parameterized supply voltage (p0210).
● Active Mode
The Active Line Module can control the DC link voltage in a rated voltage range of 3 AC
380 V to 3 AC 415 V; boost converter with controlled DC link voltage and sinusoidal
supply voltage.
● Smart Mode
In the rated voltage range of 3 AC 416 V to 3 AC 480 V, the Smart Mode is automatically
activated and the supply system transistors will be switched to be synchronous with the
supply system. The DC link voltage is not regulated, but results from the rectified supply
voltage U

The setpoint for the DC link voltage (p3510) will be preassigned automatically.
The following DC link values will be attained for the Active Line Module in Active / Smart
Mode:

1. Smart Mode can be selected using the parameter p3400.0=0.
2. Smart Mode sets itself automatically during the parameterization of the supply voltage
p0210 > 416 V.
Notice
The setpoint for the DC link voltage (p3510) can be changed. The insulation voltage of
the motors must be observed (see the NC61 catalog or the motors configuring guide)!
