3. Press “RUN” to start auto-tuning of IM magnetic flux curve dynamic test for Pr.05-00 = 1 or 6 (motor is
running). Make sure the motor executes auto-tuning under break-away load condition. Check if there
are motor parameters after auto-tuning.
Pr. 05-06 Stator Resistance (Rs) for Induction Motor 1
Pr. 05-07 Rotor Resistance (Rr) for Induction Motor 1
Pr. 05-08 Magnetizing Inductance (Lm) for Induction Motor 1
Pr. 05-09 Stator Inductance (Lx) for Induction Motor 1
4. 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

5. Execute IM sensorless FOC mode, set up the following parameters:
Pr. 00-10 = 0, set as speed mode
Pr. 00-11 = 5, set as FOC 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.
6. Select auto-tuning gain (Pr. 11-00 bit0=1), adjust ASR parameters according to the speed response.
Pr. 11-00 bit0 =1, use auto-tuning for ASR
Pr. 11-03 ASR1 low-speed bandwidth (When the acceleration of low-speed cannot follow the
acceleration command, increase the low-speed bandwidth)
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)
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.
