4. Motor auto-tuning
Set Pr.05-00 = 1 (simple rolling auto-tuning for IM) or 6 (advanced rolling auto-tuning for IM flux
curve), make sure the motor executes auto-tuning under breakaway load condition. Press “RUN” to
start auto-tuning and get the following parameters:
Parameter Description
Pr.05-06
Stator resistance (Rs) for induction motor 1 (Ω)
Pr.05-07
Rotor resistance (Rr) for induction motor 1 (Ω)
Pr.05-08 Magnetizing inductance (Lm) for induction motor 1 (mH)
Pr.05-09 Stator inductance (Lx) for induction motor 1 (mH)
If an auto-tuning error (AUE) occurs, refer to Section 14 “Fault Codes and Descriptions” for further
treatment.
AUE Error (code) Description
AUE (40) Auto-tuning error
AUE1 (142) Auto-tuning error 1 (No feedback current error)
AUE2 (143) Auto-tuning error 2 (Motor phase loss error)
AUE3 (144) Auto-tuning error 3 (No-load current I
0
measuring error)
AUE4 (148) Auto-tuning error 4 (Leakage inductance Lsigma measuring error)
5. Execute estimation of the motor inertia (optional). Press “RUN” to start the estimation after finishing
the settings for the parameters mentioned below.
Pr.00-10 = 2, torque mode
Pr.00-13 = 2, TQC sensorless
Pr.05-00 = 12, FOC sensorless inertia estimation (motor is running)
After inertia estimation is finished, check if the estimated value for Pr.11-01 is reasonable, refer to the
base value table below. (Unit: kg-cm

6. Execute IM sensorless FOC mode, set up the following parameters:
Pr.00-10 = 0, speed mode
Pr.00-11 = 5, IMFOC sensorless mode
Pr.11-00 bit0 =1, use ASR gain auto-tuning
Press “RUN” and start the Test with no-load. Accelerate the motor to the rated speed, and then
decelerate to stop, check if the motor runs smoothly.
If the motor runs smoothly, then the setting for IM Sensorless FOC is completed.
If the motor does not run smoothly, or fails to start at low frequency, then refer to the following
steps for adjustment.
