Let’s learn how to operate the control settings of the inverter fixed-length mode!
Not all brands of inverters have this function. Today, I will explain and analyze the ASB53XH with fixed-length control function. The length pulse is collected through the DI terminal (DI function selection is 30). The number of pulses sampled by the terminal is divided by the number of pulses per meter Fb-07, and the actual length Fb-06 can be calculated.
When the actual length is greater than the set length Fb-05, the multifunctional digital switch outputs the "length reached" ON signal. During the fixed length control process, the length reset operation can be performed through the multifunctional DI terminal (DI function selection is 31). The specific settings are shown in the figure below.

Notice:
1) In the fixed-length control mode, the direction cannot be identified and the length can only be calculated based on the number of pulses.
2) Only the HDI terminal can be used as the "length count input" terminal.
3) Feedback the switch output signal of the length reached to the inverter stop input terminal to create an automatic stop system.
