text: <s>[INST] Powerflex 700s VFD Running but Motor is NOT Summary: VFD shows running but motor not turningWhen the VFD is issued a run command it goes into run mode, the HIM module shows increasing DC bus and Output Current, but the RPM is bouncing in the + and - range, the direction is also bouncing from FWD and REV. It seems that it is trying to start the motor, but the motor stays still, and the VFD does not go into fault. Looking to find out what is causing this. The VFD is 600VAC, 208A and was installed in 2006. [/INST] Does this motor have an encoder on it for full flux vector control? Did anyone touch the wiring of this system between the time it did work properly and now? \\n </s>
