This document introduces the features and characteristics of ABB VFD Conveyor
The document describes a conveyor system at the Welzow Mine in Germany that has been operating since August 1999. Five conveyors of different lengths transport coal from the mine to the train‑loading area, with one conveyor having a 9% gradient.
The drive is based on ABB ACS MultiDrive, using standard motors rated at 6830 kW and 900 kW together with ten inverters (1385 kVA / 1710 kVA). IGBT supply units and diode supply units are employed in parallel to provide redundancy for the electrical equipment.

The conveyor has a 9 % gradient.
It is driven by an ABB ACS MultiDrive with standard motors of 6830 kW and 900 kW and ten inverters rated at 1385 kVA / 1710 kVA.
Redundancy is provided by using IGBT supply units and diode supply units in parallel.
