According to analog input voltage (0
～
10V), change
the level of DC injection current (0-100

).
(inverter rated current=100%, the setting of DC
injection current Cn-15 is disabled )

Run Still Level
According to analog input voltage (1.5V
～
10V),
change the level of stall prevention during running
(30%
～
200%)
(inverter rated current=100%, the setting Cn-26 is
disabled.)

value according to the then analog input voltage
(0~10V)
(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.
