In my factory have 1 Parker AC890 SD 125kW. Sometimes when it was running. I got the error message : "Desat (Over I)". I also checked about the wiring to motor and motor itself for earth fault but everything look normal. After I reset this fault, the inverter can run normal for a while (maybe few hours, few days or few months) before get this error again.
Anyone know about this fault please let me know how to solve this problem ?
Thank you very much !
