I recently acquired the DRV8243H along with the EVM, and I'm encountering two issues:
-
Currently, the nFault is triggered when the ITRIP reaches 5A, and I'm struggling to adjust it to a different value. I've attempted modifying the RIProp and changing the ITRIP to various levels, but none of these adjustments seem to resolve the issue.
-
The motor doesn't operate smoothly; every 2-3 seconds, there's a noticeable lag or spike in its performance. I'm aiming for a clean and consistent operation.
My current hardware configuration is as follows:
- Diag Level 1
- SR Level 1
- Mode Level 3 (PWM Mode)
- RIPROP 1K OHM
- ITRIP Level 5
I would appreciate any insights or suggestions to address these issues. Thank you!
