10.3.1
Upgrading firmware
When upgrading firmware you replace the converter's firmware with a newer version. Only
update the firmware to a newer version if you require the expanded range of functions of that
newer version.
Preconditions
1. Your converter's firmware is at least version V4.7.x.
2. Inverter and memory card have different firmware versions.
Procedure
To upgrade the converter's firmware to a newer version, proceed as follows:
1. Switch off the 24 V converter power supply.
2. Disconnect the connectors for power supply and motor from the converter.
3. Disassemble the converter and remove it from the ET 200pro station.
4. Insert the card with the matching firmware into the slot on the rear side of the converter
until you can feel it lock in place.
5. Plug the converter into the ET 200pro station and tighten two of the fixing screws so that
the converter can no longer unintentionally become detached from the bus module.
6. Switch on the 24 V converter supply voltage.
7. The converter transfers the firmware from the memory card into its memory.
The transfer takes between 5 and 10 minutes.
While data is being transferred, the LED RDY on the converter stays red. The SAFE LED
flashes with a variable frequency.
