The frequency converter "VLT MidiDrive" Danfoss as a successor to the VLT 2800 ago now has features such as support for PM motors, integrated safety functions or parameterization via memory module. The newly designed device provides standard Modbus RTU and optionally the most common fieldbuses Profibus, Profinet, Ethernet IP and CANopen. In addition, also improved mechanical properties with pluggable control terminals and power connection to 7,5 kW, which significantly simplifies the wiring in the field.
The Midi Drive also has a standard brake control, integrated STO (Safe Torque Off) and EMC filters in the device. This eliminates previously necessary additional external components.
A memory block is used to copy parameter sets from one inverter to another or for updates. This memory module is particularly suitable for easy commissioning and fast replacement in case of service. It can be programmed or written on the PC with the aid of a programming device. The frequency converter then automatically loads the stored data as soon as the user inserts the memory module into the existing, easily accessible slot.
The VLT Midi Drive is suitable for applications such as conveyor systems, process technology, mixers, packaging technology and power take-offs such as pumps, fans and compressors. In addition to its communication capability, the device is easy to use and to put into operation.
