Cmd. Bias 1
Total bias= Bn-06 + FBIAS1
Cmd. Bias 2
Total bias= Bn-06 + FBIAS2
According to analog input voltage (0∼10V), change
Over Tq. Level
overtorque detection level (setting of Cn-32 is disabled)
Output Voltage Total output voltage= V/F pattern voltage + VBIAS
Acc&Dec Coeff Real ACC/DEC time= ACC/DEC time (Bn-0~24) / TK
According to analog input voltage (0∼10V), change
the level of DC injection current (0-100％).
DC Brakin current
(inverter rated current=100%, the setting of DC
injection current Cn-15 is disabled )
According to analog input voltage (1.5V∼10Ｖ), change
Run Still Level the level of stall prevention during running (30%∼200%)
(inverter rated current=100%, the setting Cn-26 is disabled.)
Multi-function analog input (terminal AUX) used as
PID Command PID control reference input (0~10V). Please refer to
"PID CONTROL BLOCK DIAGRAM" on page 42.
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
Freq. Cmd. Low Bound 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).
Set the jump frequency 4, according to analog input
Freq Jump 4 voltage (0~10V), while Cn-20~Cn-23 can be used to set
the jump frequency 1~3 and their jump frequency width.
The analog value of AUX (0-1024/0-10V) can be read
Comm. Control
through RS-485 communication.
