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.
04-05=9: Jump frequency 4
Multi-function analog input AI2 can be used to adjust Jump frequency 4.
Maximum output frequency (01-02, Fmax) = 100%. Setting 11-08 to 11-10 to 0.0Hz turns of the Jump frequen-
cy function.
04-05=10: Added to AI1
Multi-function analog input AI2 can be used as a bias level for analog input AI1.
