NOTICE: Never perform Rotational Auto-Tuning for a motor connected to a load. Failure to comply could result in improper drive operation.If Rotational Auto-Tuning is performed for a motor coupled to a load, the motor parameters will be inaccurate and the motor may exhibitabnormal operation. Disconnect or decouple the motor from the load.Enter the required information from the motor nameplate. Press to proceed to the Auto-Tuning start display.Note: These instructions continue from Step 7 in “Enter Data from the Motor Nameplate”.Step Display/Result1. After setting T1-07 as illustrated in the previous section, press and confirm thedisplay is as described below:2. Press to activate Auto-Tuning. flashes.Note: The first digit indicates which motor is undergoing Auto-Tuning (motor 1 or motor2). The second digit indicates the type of Auto-Tuning being performed.3. Auto-Tuning finishes in approximately one to two minutes.u Input Data for Auto-TuningThe T1-oo parameters are used to set the Auto-Tuning input data.Note: 1. Cycling power to the drive will reset any values set during the Auto-Tuning process to factory defaults.2. For motors that are to be operated in the field weakening range, first perform the Auto-Tuning with the base data, i.e. the frequency atwhich the motor is operating with its rated voltage (base frequency). After Auto-Tuning is complete, change the maximum frequencyE1-04 to the desired value.n T1-00: Motor 1/Motor 2 SelectionSelects the motor to be tuned when motor 1/2 switching is enabled, i.e., a digital input is set for function H1-oo = 16. Thisparameter is not displayed if motor 1/2 switching is disabled.No. Name Setting Range DefaultT1-00 Motor 1/2 Selection 1 or 2 1Setting 1: Motor 1Auto-Tuning automatically sets parameters E1-oo and E2-oo for motor 1.Setting 2: Motor 2Auto-Tuning automatically sets parameters E3-oo and E4-oo for motor 2. Make sure that motor 2 is connected to the drivefor Auto-Tuning.n T1-01: Tuning Mode SelectionSets the type of Auto-Tuning to be used.
