is the voltage input from 0V to 10V,the other is the current input from 4mA to
20mA.all of them can be selected by the CN3 jumper on the control board.
4、MS speed
Select MS speed running mode in need of setting Group F5 ‘Input Terminal’
and Group FC “MS speed and PLC parameters to determine the relative relationship
between the reference signal and the reference frequency.
5、Simple PLC
Select the simple PLC mode in need of setting to Group FC “MS speed and
“PLC” Parameter to determine the reference frequency when the frequency source is
simple PLC ,
6、PID
Select the process PID control. In the meantime, it needs to set Group FA
“PID Function” .The running frequency of the inverter is that after PID functions.
Regarding PID reference source, reference quantity, and feedback source. Please
check the Group FA ‘PID Function
7、Communication reference
It means that the main frequency source is given by the host computer via
communication mode (C220/C420 series serial communication protocol for details)
F0-07
Auxiliary Frequency
