The User Manual of 580 Series General Frequency Converter

4.8.7 Setting the swing work mode

In respect of textile and chemical fiber processing equipments, the swing function in use can improve uniformity and density of spinning windings, as shown in the following figure. It is available by setting function code Fb-00 ~ Fb-04. See the detailed description of corresponding function code for the specific methods.

4.8.8 Setting multi-speed mode

If it is not required to regulate the operation frequency of frequency converter continuously, the application field with several frequency values shall be only used. When multi-speed control is available, 580 can be set with at most 16-stage operation frequency and selected by the combination of 4 DI input signals. Set function code corresponding to DI port to the function value of 12~15, which means that multi-stage frequency instruction input port is designated. The multi-stage frequency shall be set by multi-stage frequency of Group FC and the “frequency source selection” is designated to the multi-stage frequency setting method, as shown in the following figure:

Fig. 4-24 Multi-speed mode setting

In the said figure, DI8, DI4, DI9 and DI2 are selected as the designated signal input terminals of multi-stage frequency and form 4-digit binary number in order and the multi-stage frequency is selected according to the state combination value. In case of (DI8, DI4, DI9, DI2)=(0, 0, 1, 0), the state combination value is 2, the frequency value set by function code FC-02 will be selected and (FC-02) * (F0-10) is calculated to get target operation frequency. 580 can be set with at most 4 DI ports as multi-stage frequency instruction input terminals and it is allowed that less than 4 DI ports when multi-stage frequency is given. The setting place in deficiency shall be always calculated according to state 0.
