0: No action.
1: Static auto-tuning.
2: Rotational auto-tuning.
•
In the process of static auto-tuning, the stator resistance (F07.07), rotor resistance (F07.08) and leakage
inductance (F07.09) will be written into F07.07, F07.08 and F07.09 automatically.
•
For mutual inductance (F07.10) and idling excitation current (F07.11):
•
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.
•
Rotational auto-tuning (F07.06 = 2), the motor will be at rotary status and the auto-measured value will
be written into F07.10 and F07.11.
•
In the process of rotational auto-tuning, oscillation and even overcurrent might occur. At this time, press
(standard) or
STOP
(optional) to stop auto-tuning, and adjust F07.21 (oscollation-suppression mode)
and F07.22 (oscollation-suppression coefficient) to mitigate the possible oscillation.
Note: The auto-tuning is enabled only in keypad control (F00.05 = 0).
