text: <s>[INST] Motor is stuck during runtime Summary: Motor is stuck during runtimeMotor is drove by PF755. But during runtime motor isn't smooth, got stuck. Autotuning is done. Also change PF mode to VF control. [/INST] Gene, we need a LOT more information. What is the basic application (what is the load you're trying to move)? What is the motor nameplate data? Does it have encoder feedback? Did you enter the correct number of poles? When did it get stuck? At low speed? High speed? Did it follow speed commands at all? If you have a DNO file from DriveExecutive or whatever file format CCW uses, you should upload it. Uploading a DNO file for us to view along with correct motor nameplate information will get you the best support from your fellow users. \\n </s>
