6. Mechanical equivalent circuit
If Pr.05-00 is set to 2 (static test), user needs to input the no-load current value of motor
into Pr.05-05 for motor 1/Pr.05-17 for motor 2.
Set Pr.05-00=6 to begin rolling test for IM motor flux curve. This function is available
when the drive is in FOC/TQC Sensorless control. User may begin auto-tuning after
setting up the motor information.
Set up Pr.01-01, 01-02, 05-01~05-04 according to the motor nameplate information
Set Pr.05-00=6 and press Run , make sure no loading is applied to the motor
before setting Pr.05-00 to 6 and before performing auto-tuning.
When Pr.05-00=12, the drive begins FOC Sensorless inertia estimation for IM motor. This
function is available when the drive is in FOC/TQC Sensorless control. User may begin
auto-tuning after setting up the motor information.
Note: Make sure the motor parameters (no-load current, Rs, Rr, Lm and Lx) of the
drive are set before performing Pr.05-00=12 (auto-tuningfor FOC Sensorless interia
estimation for IM motor).
1. Set Pr.00-10=2 (torque mode)
2. Set Pr. 00-13=2 (TQCPG, Open-loop torque mode)
3. Set Pr. 05-00=12 and press Run to begin FOC Sensorless inertia measure
4. When the process of inertia estimation is completed, check Pr.11-01 (unit: PU Q8) and
see if the measured value is acceptable.
Set up Sensorless FOC Mode
1. Set Pr.00-10 = 0 (speed mode)
2. Set Pr.00-11 = 5 (FOC sensorless mode)
3. Set bit0 of Pr.11-00 to 1 (use ASR gain function to automatically adjust the ASR
bandwidth in Pr.11-03,11-04,11-05)
NOTE
In torque/vector control mode, it is not recommended to have motors run in parallel.
It is not recommended to use torque/vector control mode if motor rated power exceeds
the rated power of the AC motor drive.
When auto-tuning 2 motors, it needs to set multi-function input terminals (setting 14) or
change Pr.05-22 for motor 1/motor 2 selection.
The no-load current is usually 20~50% X rated current.
The rated speed can not be greater than or equal to 120f/p (f = rated frequency
Pr.01-01/01-35; P: number of motor poles Pr.05-04/05-16).
