Two running modes are available when the lowest frequency is reached:
● [b1.08]=0: Running with 0 Hz When the lower frequency is reached, the frequency converter is running with 0 Hz. To avoid the tingle at lower frequency, a hysteresis frequency width is needed.
● [b1.08]=1: Run with lower frequency If the lower frequency is reached, the frequency converter is running with the lower frequency. If command frequency is higher than [b1.07]+[b1.09] again, the output
