s
) is
measured without rotating the
motor. 20-30 Sec
The leakage inductance (sL) of
the motor is measured without
rotating the motor.
90-150 Sec
Flux current (IF), rotor time
constant (T
r
) and stator self-
inductance (Ls) is measured
simultaneously without rotating
the motor. 40-70 Sec
When auto-tuning is complete
successfully, “None” is
displayed. If error occurs
during auto-tuning, “[][] Error” is
displayed. In this case, verify
