Part Number:DRV8301
Hi,
I have successfully replicated F28027F + DRV8301 design in the custom board. Thank you very much for your forum and support.
In another design, I am trying not to use the external current sensor (due to the space shortage).
I have changed the number of current sensors from 3 to 2 in user.h file.
Board does not work properly.
Phase C scope (the one without the current sensor) is different (in terms of duty cycle) is different from A and C.
The motor does not turn.
What other changes need to be done in the program or/and schematics to get it working correctly?
Regards,
Edward.
