Infeed
2.1 Active Infeed
Drive functions
30 Function Manual, 11/2017, 6SL3097-4AB00-0BP5
● Controlled DC link voltage whose level can be adjusted (independent of line voltage
fluctuations)
● Regenerative feedback capability
● Specific reactive current setting
● Low line harmonics, sinusoidal line current (cos φ = 1)
● Several Active Line Modules connected in parallel
● Master/Slave operation for several Active Line Modules
● Parameterizable bandstop filters for Active Line Modules in chassis format
The Active Infeed closed-loop control works in conjunction with the line reactor or an Active
Interface Module and the Active Line Module as step-up controller. The level of the DC link
voltage can be defined through parameters, and, by means of the control, it is independent
of line voltage fluctuations.
The open and closed-loop control firmware of the Active Line Module runs on the Control
Unit assigned to it. The Active Line Module and Control Unit communicate via DRIVE-CLiQ.
The operating modes "parallel connection" and "master/slave connection" of the power units
are described in this manual in Section "Function modules (Page 465)".
