F07.00
Rated power of asyn. motor
0.2 - 500.0kW [Depend on MT72]
F07.01
Rated voltage of asyn. motor
0V - Controller rated voltage
[Depend on MT72]
F07.02
Rated current of asyn. motor
0.0 - 999.9A [Depend on MT72]
F07.03
Rated frequency of asyn. motor
1.00 - 100.00 [50.00Hz]
F07.04
Rated Rpm of asyn. motor
1 - 24000 [1440rpm]
F07.05
Power factor of asyn. motor
0.001 - 1.000 [Depend on MT72]
F07.06
Parameter auto-tuning of asyn. motor
0 - 2 [0]
0: No action.
1: Stationary auto-tuning.
2: Rotary auto-tuning.
Motor auto-tuning:
•
In the process of motor stationary 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)
•
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, the oscillation and even the overcurrent might occur. In this case,
press the
key to stop auto-tuning and then properly adjust the F07.18 (Oscollation-suppression
mode) and F07.19 (Oscollation-suppression coefficient) to mitigate the possible oscillation.
Note: The auto-tuning is enabled only in keypad control mode (F00.05 = 0).
Auto-tuning steps:
1. Input correct motor parameters as per its nameplate (F07.00 - F07.04).
2. F07.06 = 2, set proper Acc. speed (F03.10) and Dec. speed (F03.11) and make sure the motor is
disconnected with the load for security.
3. F07.06 = 1 or 2, then press the
key, and there with press
key to start auto-tuning. The LCD
will display “Motor para. auto-tuning”.
4. When the auto-tuning is completed, the keypad will return to stop display status and F07.06 resets to 0.
F07.07
Stator resistance of asyn. motor
0.000 - 65.535Ω [Depend on MT72]
F07.08
Rotor resistance of a syn. motor
0.000 - 65.535Ω [Depend on MT72]
F07.09
Leakage inductance of asyn. motor
0.0 - 6553.5mH [Depend on MT72]
F07.10
Mutual inductance of asyn. motor
0.0 - 6553.5mH [Depend on MT72]
F07.11
Excitation current of asyn. motor
0.0 - 999.9A [Depend on MT72]
