FAQ

The Danfoss VLT 2800 series is officially declared 'Obsolete' by the manufacturer. It has been succeeded by newer series like the VLT Micro Drive FC 51.

Yes, if the part number (195N1028) and type code match your existing unit, it can be used as a direct replacement. It is crucial to upload the parameters from the old drive or re-commission the new drive according to the application's requirements.

You should always perform an Automatic Motor Adaptation (AMA) via the control panel. Additionally, verify motor data parameters such as motor voltage, frequency, current, and nominal speed. Also, set the acceleration/deceleration ramps and speed limits to match your application's needs.
