Hello @NP,
the torque-current relationship of a motor is defined by the motor Torque Constant (Kt).
Kt = T (torque) / I (armature current) [Nm/A]

Hi Cristiana, does it represent that the STMotor Pilot read Torque value (unit s16A), equal to current (A) * 65536?
As in the source code mentioned:
/* Set the backup value of hTargetFinal. */
wCurrentReference = ((int32_t)pHandle->TargetFinal) * 65536;

On speed_torq_ctrl.c there's an explanation STC_ExecRamp(),
Current(digit) = [Current(Amp) * 65536 * Rshunt * Aop] / Vdd micro
looks like Current(digit) is 16 bit, shall s16A change to Volt(digit)?
Could you help advise? Thanks.
