  13. Software for A0J2

    Hi, It is possible that the project was created with Melsec Medoc. It works under DOS. You may try to download the project with GX Developer, you only need a cable SC-09 and we use 25 pin sockets. Possible is parts of the program may be missing or colored yellow.
  14. FR S520S inverter reverse frequency problem

    Hi Franz, There is no problem using Terminal 4 to set the output frequency. Then configure the AU of another  terminal RL.  When we want to work with the current input, we supply + 24V(terminal PC) to the terminal that we have configured as an AU (RL in my example ). It is necessary to use STF and STR terminals for START forward / START reverse.
  15. FR S520S inverter reverse frequency problem

    Hi Franz, Check Pr 63 how it is set up. It is for setting the STR terminal.  If set to 0, 1, 2 is used for low, medium or high speed. Reverse is set ---. Good luck!
