Hello,

Vsense is the voltage on CS (Current Sense) pin. This pin acts as a current generator and a current proportional to the motor current is sourced from this pin. The voltage on the pin depends thus on the motor current and on resistor placed between CS and GND. The voltage on CS pin is forced to be equal to VsenseH in case of faults (refer to diagnostic table on the datasheet).

Thanks Youï¼� but how can I fix the resistance of Rsense ?
