Active Interface Modules are used in combination with Active Line Modules in chassis format. Active Interface Modules contain a Clean Power Filter with basic interference suppression, the pre-charging circuit for the Active Line Module, the line supply voltage sensing circuit and monitoring sensors. The bypass contactor is an integral component in frame sizes FI and GI, which ensures a highly compact design.

The vast majority of line harmonics are suppressed by the Clean Power Filter.

The scope of supply of the Active Interface Modules includes:

• Frame size FI:
  • 0.60 m (1.97 ft) DRIVE-CLiQ cable for connection between Active Interface Module and Active Line Module
  • 1.45 m (4.76 ft) DRIVE-CLiQ cable for connection between Control Unit or SINUMERIK NCU and first Motor Module
• Frame size GI:
  • 0.95 m (3.12 ft) DRIVE-CLiQ cable for connection between Active Interface Module and Active Line Module
  • 1.45 m (4.76 ft) DRIVE-CLiQ cable for connection between Control Unit or SINUMERIK NCU and first Motor Module
