7. Motor parameter auto-tuning
1. Do parameter auto-tuning in keypad mode.
2. Wire correctly. Power on, and set motor parameter (F08.00 - F08.04) on keypad.
3. Below are auto-tuning methods for V/f and vector control.
Control mode Auto-tuning methods (recommended)
V/f control
Manually torque boost
Static, rotary and stator resistance auto-tuning
Auto torque boost
Static and rotary auto-tuning
Vector control Rotary auto-tuning
Static auto-tuning:
F08.06 = 1 (stationary auto-tuning), press button ( ) to exit to parameter display status at
stop. Press button ( ) to start auto-tuning.
When auto-tuning finished, F08.07 - F08.09 are refreshed automatically.
Ref. code Function Ref. code Function
F08.07 Stator resistor of motor F08.09 Leakage inductance of motor
F08.08 Rotor resistance of electron 1
Rotary auto-tuning:
Free the motor from load before start rotary auto-tuning.
F08.06 = 2 (rotary auto-tuning), press button ( ) to exit to parameter display status at stop.
Press button ( ) to start auto-tuning.
Oscillation and over-current may occur during motor rotary. In this case, press button ( )
immediately to stop tuning, and adjust Acc. / Dec. time, F09.15 (LF oscillation-suppression of motor)
and F09.16 (HF oscillation-suppression of motor) to reduce the oscillation.
When auto-tuning finished, F08.04 and F08.07 - F08.16 are refreshed automatically.
Ref. code Function Ref. code Function
F08.04 Rated rpm of motor F08.12 Core saturation coefficient 1 of motor
F08.07 Stator resistance of motor F08.13 Core saturation coefficient 2 of motor
F08.08 Rotor resistance of motor F08.14 Core saturation coefficient 3 of motor
F08.09 Leakage inductance of motor F08.15 Core saturation coefficient 4 of motor
F08.10 Mutual inductance of motor F08.16 Core saturation coefficient 5 of motor
F08.11 Exitation current of motor
To measure the stator resistance:
F08.06 = 3 (Test stator resistance), press button ( ) to exit to parameter display status at
stop. Press button ( ) to start auto-tuning.
When auto-tuning finished, F08.07 is refreshed automatically.
