H44: Leakage Inductance (Ls)
Range: 0 - 300.0 mH
Description: This is leakage inductance of the stator and rotor of the motor.
•
H41: When H41 is set to 1, 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.
H45: Sensorless P Gain
Range: 0-32767 (Default: 1000)
Description: P gain for Sensorless control. Set H40 to 3 (Sensorless vector control) to
display this parameter).
H46: Sensorless I Gain
Range: 0-32767 (Default: 100)
Description: I gain for Sensorless control

Do not enter any incorrect value as stator resistance and leakage
inductance. Otherwise, the function of Sensorless Vector
Control and Auto Torque Boost could be deteriorated.
