NACT_A (Speed setpoint A (16 bit))
● Actual speed value with 16-bit resolution.
● The speed actual value is normalized in the same way as the setpoint (see NSOLL_A).
NACT_B (Speed setpoint B (32 bit))
● Actual speed value with 32-bit resolution.
● The speed actual value is normalized in the same way as the setpoint (see NSOLL_B).
