i need to monitoring the VSD by yaskawa from my ABB Freelance Dcs and connect using RS-485, i've got transmit n receive value in the dcs but there are have big differential plus i've got a wrong value that appear in the VSD display. when i try to stimulate using Modsim to my DCS i'e got the actual value that key-in from modsim.
i do not what to do since this yaskawa vendor is not willing to help plus i have to search all the parameter required by myself with looking into their manual.
