Gatekill Error

[DASIREDDY4608]

Hi Team,

We are doing some experiments using the IMD111T. We want to run the motor using my power board and Infineon IMD111T motor control IC. We did connect all the required cross wires between the IMD111T solution and my power board. We can do parameter and software programming but cannot run the motor-identified gate kill error.

Could you please help me on this how to overcome the issue.

Hi @DASIREDDY4608,

The gatekill fault can arise due to multiple reasons:

• Improper shunt configuration ( If the power board uses single shunt but the MCE Wizard is configured to leg shunt)
• Improper current feedback gain and input scaling.
• Improper ADC offset voltage.

Please check the above parameters in the MCE Wizard configuration and modify based on power board.

If the problem still exists can you please share the power board schematics, Control board schematics and MCE Wizard configuration file( .mc2) this will help us to understand the issue better.

Thanks,

Krupashankar
