L6470 step loss

In a L6470 the microcontroller sends a Move command in 128-microstepping type; then, after a zero is read in the busy flag (so the movement has finished), the absolute position is read but the value read is smallest than the value introduced as Move parameter. I have noticed that the STEP_LOSS_A and the STEP_LOSS_B flags are zero so is it possible that some microsteps had lost and that was the reason that both values were different?
