Hello Team,
I'm Yuta Kurimoto FAE from TIJ.
Our customer has been evaluating the DRV8343H-Q1 EVM board and they faced some issue.
Case 1:
During the sensorless motor rotation, they intentionally shorted the phase A and phase B. Then the GUI represented phase fault.
After that they cleared the fault, and they connected the each phase correctly.
However they can't drive the motor anymore. They are not sure the reason. Do you have any idea?
Case 2:
Before starting the motor, they removed the 30A fuse of each phase. Then they started the motor correctly.
After that they attached the fuse again, but they can't drive the motor anymore. They are not sure the reason. Do you have any idea?
I will visit customer tomorrow and will have experiment with customer.
So I'd like to know what the reason is assumed before the experiment.
Thanks,
Yuta Kurimoto
