A: In GD300-01A-RT model for Atlas Copco, we are facing regular IGBT failures. What could be the reason and recommendation?
During analysis, it was found that parameter P29.03 was not matching the motor nameplate kW rating. The parameter has now been updated as per the motor nameplate specifications.
Recommendation:
Do not modify any parameters in the P29 group, as this parameter group must always remain exactly the same as the VFD nameplate information. Any mismatch may lead to improper drive operation and can result in repeated IGBT failures.
