Also ensurePr 10.030 and Pr 10.031 and Pr 10.061 are set correctly, otherwise premature ‘It.br’ trips may beseen).AutotuneThe drive is able to perform either a stationary or a rotating autotune. The motor must be at a standstillbefore an autotune is enabled. A rotating autotune should be used whenever possible so the measuredvalue of power factor of the motor is used by the drive.• A stationary autotune can be used when the motor is loaded and it is not possible to uncouple theload from the motor shaft. A stationary autotune measures the stator resistance of the motor andthe dead time compensation for the drive. These are required for good performance in vectorcontrol modes. A stationary autotune does not measure the power factor of the motor so the valueon the motor nameplate must be entered into Pr 09.• A rotating autotune should only be used if the motor is uncoupled. A rotating autotune first performsa stationary autotune before rotating the motor at 2 /3 base speed in the direction selected. Therotating autotune measures the power factor of the motor.To perform an autotune:• Set Pr 38 = 1 for a stationary autotune or set Pr 38 = 2 for a rotating autotune• Close the Drive Enable signal (apply +24 V to terminal 11). The drive will display ’rdy’.• Give a run command (apply +24 V to terminal 12 - Run forward or terminal 13 - Run reverse onUnidrive M200; press keypad start button on M201). The display will flash ’tuning’ while the drive isperforming the autotune.• Wait for the drive to display ‘inh’ and for the motor to come to a standstill.If the drive trips, see Chapter 12 Diagnostics on page 129.• Remove the drive enable and run signal from the drive.Save parameters Select 'Save' in Pr 00 or Pr mm.000 (alternatively enter a value of 1001) and press the redreset button.Run Drive is now ready to run Motor rated current in Pr 06 (Amps) Motor rated speed in Pr 07 (rpm / min-1 ) Motor rated voltage in Pr 08 (Volts) Motor rated power factor (cos ) in Pr 09MOT. 3 LS 80 L TN 734570 BJ 002 Kg 940 C S1IP 55 I cl.FV Hz min kW cos-1 A230 50 2800 0,75 0,83 0,3123 4Pr 02t100HzPr 03 tPr 04A rotating autotune will cause the motor to accelerate up to 2 /3 base speed in the directionselected regardless of the reference provided.
