Part Number: DRV8301
My customer is using the DRV8301-69M-KIT to evaluate and characterize the motors using the instaspin labs. The motor works fine with no load, but once the load (propeller) is attached there is an overcurrent issue. Is there a setting that needs to be changed? or is there other labs that the customer needs to implement to fix this issue?
One other question the customer has is the DRV8353 or DRV8301, capable of driving a motor to 40,000RPMs? and can it be implemented with the current CCS instaspin software?

Thanks, Errol. Please find attached modified user.h file and the proj_lab05b.c - it would be surprising that we'd have issues spinning up with load levels above 5V on this board. Could really use your support in debugging.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Hi Errol, Adnan,
The over-current is likely caused by the driver reacting to the high current when loaded. You may need to increase the threshold through the driver tab.

Attached is the drv8301.c file. I'm not sure what level it is currently configured to, what it needs to be adjusted to, and which variable to update.
As far as I know, this setting hasn't been modified from the default settings within the DRV8301-HC-C2-KIT and associated project files. I'm barely able to get it to support current levels above 3A. This doesn't make sense, since the kit was designed for 60A operation. Maybe we're missing something...
