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.Stationary Auto-Tuning for Line-to-Line Resistance• Perform when entering motor data manually while using motor cables longer than 50 m.• If the motor cables have been replaced with cables more than 50 m long after Auto-Tuning has already been performed, useStationary Auto-Tuning for line-to-line resistance.u Auto-Tuning Interruption and Fault CodesIf tuning results are abnormal or the OFF key is pressed before completion, Auto-Tuning will be interrupted and a fault codewill appear on the HOA keypad.BLOREESCRUN STOPENTERRESETDIGITAL OPERATOR JVOP-180ALOREESCRUN STOPENTERRESETDIGITAL OPERATOR JVOP-180 ALM ALMDRV-OFFX.XX Hz/ X.XXATune Proceeding<<<<<< >>>>>>DRV-OFFEr-03STOP keyRESETA – During Auto-Tuning B – Auto-Tuning AbortedFigure 4.12 Auto-Tuning Aborted Displayu Auto-Tuning Operation ExampleThe following example demonstrates Rotational Auto-Tuning for V/f.n Selecting the Type of Auto-TuningStep Display/Result1.
