The User Manual of 580 Series General Frequency Converter

4.8.3 Run command switching and frequency reference binding

Through F0-27 setting, the three command sources of frequency converter can set their respective frequency source, as shown in the figure above. After the frequency binding channel (corresponding to F0-27) is set for the designated command channel (F0-02), main frequency source X or auxiliary frequency source Y will not take effect, but the given frequency channel defined by F0-27 will be used for determination.

4.8.4 The usage of frequency source given by A1 analog

The frequency source of 580 is given by analog input terminal. 580 control panel is set with 2 analog imputer terminals (AI1, AI2) and the optional I/O expansion card will provide an additional analog input terminal (AI3).

The following examples are given to introduce the specific usage.

1. AI1 voltage input connecting to the potentiometer as frequency source (2V-10V corresponds to 10 Hz -40Hz)

Fig. 4-19 Function code setting of AI1 voltage input frequency reference

2. AI2 current type input connecting to 4DA module of PLC as the frequency source (4-20mA corresponds to 0 Hz -50Hz)

Fig. 4-20 Function code setting of AI2 current type input frequency reference

Notes:

1) 580 control panel is set with 2 analog input terminals (AI1, AI2) and the optional expansion card is set with an additional analog input terminal (AI3).

2) AI1 is 0V～10V voltage type input; AI2 is 0V～10Vvoltage input or 4mA～20mA current input, selected by Jumper J8 on the control panel; AI3 is -10V～10V bipolar voltage signal input.

3) When AI is given as frequency, voltage/current input corresponds to 100.0% setting, which means the percentage of maximum frequency F0-10.

4) The temperature transmitter used for the given analog shall be connected to AI3 terminal of I/O expansion card.

5) Five groups of correspondence curve can be preset for 580 and freely selected by F4-33. The input value and target frequency in each group of curve shall be set by means of function code F4-13 ～F4-27 as well as function code in Group A6.
