F07.06 Motor parameter auto-tuning 0 - 2 [0]
0: Auto-tuning is disabled.
1: Stationary auto-tuning.
2: Rotary auto-tuning.
Motor auto-tuning:
• In the process of stationary auto-tuning, the stator resistance (F07.07), rotor resistance (F07.08) and
leakage inductance (F07.09) will be auto-measured and written into F07.07, F07.08 and F07.09
automatically.
• For mutual inductance (F07.10) and idling excitation current (F07.11).
• At stationary 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;
• At rotary 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.
• When the motor is in rotary status, oscillation and even overcurrent might occur. In this case, 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 keypad control mode (F00.05 = 0).
