Hi all,
I try to run motor using the DRV8711 but have not got any success so far. When I enable the motor through SPI getting 0x04 fault error over status registers which is over-current protection error. I realised that the BEMF left open in schematics. Do you think it could be reason of getting this error? Or any idea how to debug the board for that specific problem?
Here my design parameters:
VM:24V Rsense:0.03 ohms MOSFET: BUK7M10-40E Motor Current:0.8A/phase Motor Resistance 13 ohm/phase
Any help would be appreciated.
Thanks.
