(Max. output frequency (Cn-02) corresponds to the
100% analog output. The actual lower-limit is
determined by the maximum of Cn-19 and the value
corresponding to the multi-function analog input
terminal).

Jump frequency setting4 Freq Jump 4
Set the jump frequency 4, according to analog input
voltage (0~10V), while Cn-20~Cn-23 can be used to set
the jump frequency 1~3 and their jump frequency width.
