Rotational Auto-Tuningis best suited for applications requiring high performance over a wide speed range.• If it is not possible to decouple the motor and load, reduce the load so it is less than 30% of the rated load. PerformingRotational Auto-Tuning with a higher load will set motor parameters incorrectly, and can cause irregular motor rotation.• Ensure the motor-mounted brake is fully released, if installed.• Connected machinery should be allowed to rotate the motor.n Notes on Stationary Auto-TuningStationary Auto-Tuning modes analyze motor characteristics by injecting current into the motor for approximately one minute.WARNING! Electrical Shock Hazard. When executing stationary Auto-Tuning, voltage is applied to the motor before the motor rotates. Donot touch the motor until Auto-Tuning is completed. Failure to comply may result in injury or death from electrical shock.WARNING! Sudden Movement Hazard. If installed, do not release the mechanical brake during Stationary Auto-Tuning. Inadvertent brakerelease may cause damage to equipment or injury to personnel. Ensure that the mechanical brake release circuit is not controlled by thedrive multi-function digital outputs.u Auto-Tuning Interruption and Fault CodesIf tuning results are abnormal or the STOP key is pressed before completion, Auto-Tuning will be interrupted and a fault codewill appear on the digital operator.BLOREESCRUN STOPENTERRESETDIGITAL OPERATOR JVOP-180ALOREESCRUN STOPENTERRESETDIGITAL OPERATOR JVOP-180 ALM ALM- A.TUNE -X.XX Hz/ X.XXADRVTune ProceedingRdyFWD<<<<<< >>> >>>- MODE -Er-03STOP keyDRVFWD RESETA – During Auto-Tuning B – Auto-Tuning AbortedFigure 4.10 Auto-Tuning Aborted Displayu Auto-Tuning Operation ExampleThe following example demonstrates Stationary Auto-Tuning for Line-to-Line Resistance.n Selecting the Type of Auto-TuningStep Display/Result1.
