text: <s>[INST] PowerFlex 755 not turning motor Summary: PowerFlex 755 will not spin motor, HMI shows RPMs thoughWe have a PowerFlex 755 that is not spinning the motor. The HMI and the analog display on cabinet show RPMs though there is no movement on motor. When checking for voltage there is nothing coming out of the VFD to the motor. We checked all the parameters, fuses, timers, the issue is with VFD. The HMI doesn't show any faults, the STS light blinks green. Any suggestions? [/INST] What mode have you set the drive? Are you in V/Hz, Sensorless Vector, Flux Vector / Open Feedback, or Flux Vector Encoder Feedback? If you're in ANYTHING other than V/Hz, did you perform a motor auto-tune? From where is your analog display getting its signal to show RPM? Let's start with these questions and build from there. \\n </s>
