Asynchronous motor parameter auto-tuning
0: No action.
1: Motor static auto-tuning.
2: Motor rotation auto-tuning.
Motor auto-tuning:
• In the process of motor static auto-tuning, the stator resistance (F07.07), rotor resistance (F07.08)
and leakage inductance (F07.09) will be auto-measured and written into corresponding
parameters automatically.
• For mutual inductance (F07.10) and excitation current (F07.11),
• If at static auto-tuning (F07.06 = 1), it will auto calculate according to F07.05 and F07.02, then
write the result into F07.10 and F07.11;
• If at rotation auto-tuning (F07.06 = 2), the motor will be at rotation state and the auto-measured
value will be written into F07.10 and F07.11.
• When the motor is in rotation state, the oscillation and even the overcurrent might occur. In this
case, please press the key to stop auto-tuning and then properly adjust the F07.21
(oscollation-suppression mode) and F07.22 (oscollation-suppression coefficient) to mitigate the
possible oscillation.
Note: The auto-tuning is enabled only in panel control mode (F00.05 = 0).
Auto-tuning procedures:
1．Input correct motor parameters as per its nameplate (F07.00－F07.04).
2．When F07.06 is set as 2, please set the proper Acc speed(F03.10) and Dec speed (F03.11) and
make sure the motor is disconnected with the load for security.
3．Set F07.06 as 1 or 2 firstly, then press the key, and therewith press key to start
auto-tuning. The LCD will display “Motor para. auto-tuning”.
4．When the auto-tuning is completed, the panel will return to stop display state and the F07.06 will be
reset to 0.
