Setting H41 as 1, the inverter measures the motor parameter.
The measured motor parameters are used in Auto Torque Boost and Sensorless Vector
Control.
CAUTION:
Auto tuning should be executed after stopping the motor. Motor shaft must not run during Auto
tuning.
H41: When H41 is set to 1 and press the Enter (
) key, Auto tuning is activated and “TUn” will appear
on the display. When finished, “H41” will be displayed.
H42, H44: The values of motor stator resistance and leakage inductance detected 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 set 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 is correctly calculated
and auto-tuning of leakage inductance (H44) is interrupted, the measured value of H42 is used and the
default of leakage inductance (H44) is set.
See following pages for the motor parameter default values.
CAUTION:
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.
