How to Troubleshoot an option card used for Altivar variables speed drive?

1. Hardware check
- Check if option card is inserted into Altivar drive properly. For example line marked on VW3A3607 profibus option card has to be aligned with ATV320 edge.
- Look inside the ATV slot for the option card whether all pins are ON and none of them is bent. Use light to look into the ATV slot

2. Software compatibility
- check if the firmware of the option card and firmware of the drive are compatible. For example, VW3A3607 profibus card can go with ATV320 if the profibus card has fw 1.12 IE01 (1.CIE01) or newer.

3. Identification
- Check the identification menu or connect via somove to see whether the option card is identified by the drive (reference and version).

4. Configuration
- For some of the cards, e.g. profinet, it is necessary to configure the communication menu (address,...) to avoid communication faults on ATV
