04-05=8: Frequency lower limit
Multi-function analog input AI2 can be used to adjust the lower limit of frequency reference.
Maximum output frequency (Fmax, 01-02) = 100%. The actual lower limit is determined by the maximum value
of 00-13 (frequency lower limit) and level of the multi-function analog input AI2.
