Motor parameters will be automatically measured.

The measured motor parameters in H41 can be used in Auto Torque Boost and Sensorless Vector Control.

!

ATTENTION:Auto tuning should only be executed after motor has stopped. Motor shaft must not run by the load during H41[Auto tuning].

H41: When H41 is set to 1 and press the Enter (ò) key, Auto tuning is activated and “TUn” will appear on the LED keypad. When finished, “H41” will be displayed.

H42, H44: The values of motor stator resistance and leakage inductance detected in H41 are displayed, respectively. When Auto tuning is skipped or H93 – [Parameter initialize] is done, the default value corresponding to motor type (H30) will be displayed.

Press the STOP/RST key on the keypad or turn on the EST terminal to stop the Auto Tuning.

If Auto tuning of H42 and H44 is interrupted, the default value will be set. If H42 and H44 are finished and auto-tuning of leakage inductance is interrupted, the measured value of H42 and H44 are used and the default of leakage inductance is set.

See page for motor parameter default values.

!

ATTENTION:Be sure accurate values are entered for stator resistance and leakage inductance. Otherwise, the performance of Sensorless vector control and Auto torque boost could be compromised.
