4 posts in this topic

Hello! I have i little problem with comunication between the PLC and Yaskawa invertet. I set up all the parameter in the inverter and i add all the communication card to PLC. But i don't know how to made a comunication between this two devices. Exaple how do i add a simple start comand ower Ledder diagram. What modules do i need to use in ledder diagram that the inverter can understad what i want to do? Exaple: to start, to stop, and to add a referent frekvency to the driver? I am little bit confused, i was search all the topic on this forum but i cant find any exaples of programs how to made a program for that. Thanx Best regards! Edited by arpix

See here. I assume you are using Modbus RTU. The documentation for this is for Omron inverters, but works well with Yaskawa, if you know the correct registers / coils to use. http://forums.mrplc.com/index.php?app=downloads&showfile=867
