The VLT Memory Module MCM 103 is an optional component for the VLT Midi Drive FC 280 frequency converter. It serves two primary functions:
- Memory Module: Stores firmware and parameter settings, allowing for easy copying to new frequency converters of the same power size.
- Activation Module: Enables locked features within the frequency converter firmware.
The module is protected from direct viewing. To view or transfer files, a separate Memory Module Programmer (ordering number 134B0792) is required.
Installation
- Remove Cover: Use a screwdriver to remove the plastic front cover of the frequency converter.
- Open Container: Open the lid of the memory module container located inside the unit.
- Install Module: Plug the memory module into the designated socket within the frequency converter.
- Close Container: Close the lid of the memory module container.
- Replace Cover: Mount the plastic front cover back onto the frequency converter.
Operation
The memory module can be inserted or removed while the frequency converter is in operation; however, it only becomes active after a power cycle. When the frequency converter powers up, the data on the converter is automatically stored into the memory module.
Safety
Personnel responsible for mounting or dismounting the memory module must be familiar with the safety instructions and measures described in the VLT Midi Drive FC 280 Operating Guide.
