Ref. Low Bound
Adjust the lower limit (0 to 100%) of
frequency command based on analog
input, the maximum output = 100%. The
lower limit of frequency command is the
greater one of the actual frequency
command’s lower limit 00-13 or the
multi-function analog input.

04-05=0: Auxiliary frequency
When parameter 00-05 = 1 (main frequency from external control) the auxiliary speed reference frequency can be
activated via the multi-speed input commands (see table 4.4.7). The auxiliary frequency command can be set via
AI2. The maximum output frequency is set by 01-02, Fmax =100%.
04-05=1: Frequency Reference Gain (FGAIN)
Multi-function analog input AI2 can be used to adjust the frequency reference gain of analog input AI1.
The total frequency reference gain of terminal AI1 is the internal gain set by parameter 04-02 times FGAIN.
The maximum frequency reference for AI1 is 100%.
