text: <s>[INST] Powerflex4, 40, 4M, 525 not following orders.... Summary: They do not follow cmd. freq. nor stop when told to. Hi all, Has anyone experienced their drives not following orders, such as command freq. (the drives tend to hunt around, even to go beyond max freq.) or what's worse, they don't stop when told to. When set to Decel to a stop, the drive tends to keep outputting a floating freq. (again, could be higher than max setting) and just stays running. One way to stop this is to set the drive to coast to a stop, but that's just a band aid. The drives are running as V/Hz. Now the problem seems to be related to the incoming 3ph power (imbalance from Edison), I can change up the three leads and the problem goes away sometimes, but I can't account for this when in the installed facility, this happens and the incoming seems fine and balanced. Any thoughts ?? Especially how to remedy this, I can't have drives not stopping on command. William [/INST] What is the slip frequency set to on each drive? \\n </s>
