Over Tq. Level
According to analog input voltage (0∼10V), change
overtorque detection level (setting of Cn-32 is disabled)

Scaling of ACC/DEC time(TK) Acc&Dec Coeff
Real ACC/DEC time= ACC/DEC time (Bn-0~24) / TK
07
DC injection braking DC Brakin current
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 )
08
Stall prevention level
during running
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.)

PID Command
Multi-function analog input (terminal AUX) used as
PID control reference input (0~10V). Please refer to
“PID CONTROL BLOCK DIAGRAM” on page 42.

Frequency command
lower limit
Freq. Cmd. Low Bound
Change the frequency command lower-limit (0-100％)
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).
11
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.

application
Comm. Control
The analog value of AUX (0-1024/0-10V) can be read
through RS-485 communication.
