The User Manual of 580 Series General Frequency Converter

4.8.10 Setting the fixed length control mode

580 is set with the fixed length control function, the length pulse is collected by DI (DI function is set to 27) terminal, the pulse number sampled by the terminal shall be divided by pulse number per meter FB-07 to get actual length FB-06. When actual length is more than the set length FB-05, “the length” of multifunctional digital DO output reaches ON signal.

In the fixed length control process, the length can be reset (DI function is set to 28) through multifunctional DI terminal. The specific setting is as shown in the following figure.

Fig. 4-26 Function code setting of the fixed length control mode

Notes: 1) It is impossible to identify the direction in the fixed length control mode, but the length shall be only calculated according to the pulse number.

2) DI5 terminal shall be only used as “length count input” terminal

3) Report DO output signal that the length reaches to the stop input terminal of frequency converter as automatic stop system.
