General characteristics of the Line Modules
• Connection voltage: 3AC 380 V -10% to 3AC 480 V +10% (-15% <1 min) (47 to 63 Hz)
• Suitable for TN, TT, and IT supply systems
• 100% regenerative feedback capability
• Internal/external air cooling
• Short-circuit/ground-fault-proof during the precharge phase
• Integrated DC link and electronics current busbar connection
• LEDs for indicating statuses and for diagnostic purposes
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
in the drive line-up.
– Integration in system diagnostics
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 is precharged via the Line Module is determined using
the following formula:
