Line Modules Booksize
3.1 Introduction
Characteristics of the Active Line Modules
• Regulated DC link voltage
• Regenerative feedback capability
• Sinusoidal line currents
• Electronic type plate
• DRIVE-CLiQ interface for communication with the Control Unit and/or other components
Characteristics of the Smart Line Modules
• Unregulated DC link voltage
• Regenerative feedback capability
• Square-wave line currents
Frequency with which the DC link is precharged
The frequency with which the DC link capacitance is precharged via the Line Module is
determined using the following formula:
The DC link capacitances of the individual components can be taken from the relevant
technical data.
