The final speed after the ramp-up is set in user.h as part of the motor parameters. This speed, specified in Hz, should be set depending on the phase inductance range. For single digit µH inductances this value should be around 50 Hz. For tens to hundreds of µH inductances, a value of 20 Hz should be enough to allow an accurate identification of the inductance.
// During Motor ID, maximum commanded speed in Hz
#define USER_MOTOR_FLUX_EST_FREQ_Hz (20.0)
Keep in mind that increasing this frequency might require increasing the ramp up time, so that the ramp up state is long enough to allow reaching the final frequency with the specified acceleration. The previous plot also shows the final frequency of 20 Hz.
