VLT® All-mode Filter MCC 201

VLT® All-mode Filter MCC 201 output filters are dual mode low-pass sine-wave filters operating differential mode and common mode. These filters suppress the switching frequency component from the drive and smooth out the phase-to-phase and phase-to-ground output voltage of the drive to become sinusoidal.

Long or unshielded motor cables

The VLT® All-mode Filter MCC 201 technology with reduction of differential mode and common mode interference at the inverter output enables the use of extremely long motor cable lengths. This filter also supports the use of unshielded motor cables.

Electrical interference

The VLT® All-mode Filter MCC 201 efficiently filters differential and common mode interferences. Through the connection to the intermediate circuit of the VLT® drive, the common mode currents returns to the source of the drive. This configuration is highly effective at preventing this

high-frequency interference current from spreading across the electrical installation.

Bearing current

Inverter-based bearing currents in the motor may be caused by the common mode voltage from the drive IGBT output stage. The VLT® All-mode Filter MCC 201 provides a real solution to those effects, for all practical purposes completely eliminating the common mode distortions, which considerably extends motor lifetime.

Quality and operation

The VLT® AutomationDrive FC 302, VLT® AQUA Drive FC 202, and the VLT® HVAC Drive FC 102 have been designed to operate the VLT® All-mode Filter MCC 201 by an automated feature, which will enable matching operating conditions. The drive requires DC-link connection for common mode feedback from filter, R+ terminal (terminal 82). The VLT® All-mode Filter MCC 201 is designed to match the look and quality of the FC series drives.
