If an auto-tuning error (AUE) occurs, refer to Chapter 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 inertia estimation for IM (optional), press RUN key to start the process.
Set Pr.00-10 = 2, torque mode
Set Pr.00-13 = 2, IM TQC sensorless
Set Pr.05-00 = 12, FOC sensorless inertia estimation
Check if the estimated value for Pr.11-01 is reasonable (refer to the explanation of Pr.11-00) when
the inertia estimation process is finished, the base value table of inertia is as below (unit: kg-cm
2
).

6. Execute IMFOC Sensorless mode, set up the following parameters:
Set Pr.00-10 = 0, speed mode
Set Pr.00-11 = 5, IMFOC Sensorless
Set Pr.11-00 bit0 = 1, use ASR gain auto-tuning
Press RUN key and start the no load test. 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 IMFOC Sensorless is completed.
 If the motor does not run smoothly or fails to start at low frequency, then refer to the following
steps for adjustment.
7. Select auto-tuning gain (Pr.11-00 bit0 = 1), adjust ASR parameters according to the speed response.
Set Pr.11-00 bit0 = 1, use auto-tuning for ASR
Set Pr.11-03 ASR1 low-speed bandwidth (When the acceleration of low-speed cannot follow the
acceleration command, increase the low-speed bandwidth)
Set Pr.11-04 ASR2 high-speed bandwidth (When the acceleration in high speed causes vibration or
cannot follow the acceleration command, increase high-speed bandwidth)
Set Pr.11-05 Zero-speed bandwidth (If the response of start-up is slow or incapable, increase
zero-speed bandwidth)
 The bigger the setting value for ASR bandwidth, the faster the response.
 The low-speed bandwidth cannot be set too high, or the observer will diverge.
