I'm trying to troubleshoot an 890/motor running sensorless vector. I'm new to Parker VFDs. speed demand is 100%, amps are roughly 2/3 of FLA, speed error is 13%, torque demand is 149%, VFD is sending 53hz . shouldn't the VFD increase amps and hertz to meet demand? I have skimmed the manual, performed multiple autotunes. after one autotune everything looked good. speed error<1%, 60hz... we had to make a parameter change (autotuned it again afterwards) and the issues came back. any help would be appreciated.
