Long time reader first time poster, I will try to keep it short but there is a lot of variables here. I have a Mitsu A846 running a 1000 ton press. I have it set to real sensorless vector control. It is a 160kW 4 poll motor 460V and 240A. We are replacing some Powerflex 700s drives and the one that is still installed is running a peak current of 190A. Yet for some reason the mitsu is peaking at 260A with ruffly the same load. I would expect them to be about the same I have the FLA set at 260 and its kissing that when the press cycles. I did a static tune (offlline) since we are using the motor control we are. I will run a rotating tune when I get a chance. Just hoping someone on here has seen this before.
Oh we have two of them installed both running higher than expected current so no mechanical issues causing more load.
