Incorrect motor parameters may result in unstable running of the motor or even failure of
normal running. Correct tuning of the parameters is a requirement of vector control
performance.
Each time when F801 rated power of the motor is changed, the parameters of the motor
(F806-F809) will be refreshed to default settings automatically. Therefore, be careful while
amending this parameter.
The motor’s parameters may change when the motor heats up after running for a long time. If
the load can be disconnected, we recommend auto-checking before each running.
When F104=3, and F810=60.00, F802 will change to 460V automatically, F805 will change to
1800 automatically.
When F104=3, and F810=50.00, F802 will change to 380V automatically, F805 will change to
1460 automatically.
When F810 is set to the other values, F802 and F805 will not change automatically.
F802 and F805 can be set manually.
F806 Stator resistance
Setting range: 0.001
～
65.00Ω
F807 Rotor resistance
Setting range: 0.001
～
65.00Ω
F808 Leakage inductance
Setting range: 0.01
～
650.0mH
F809 Mutual inductance
Setting range: 0.1
～
6500mH
The set values of F806
～
F809 will be updated automatically after normal completion of
parameter tuning of the motor.
The inverter will restore the parameter values of F806
～
F809 automatically to default standard
parameters of the motor each time after changing F801 rated power of the motor;
If it is impossible to measure the motor in situ, input the parameters manually by referring to the
known parameters of a similar motor.
Take a 3.7kW inverter for the example: all data are 3.7kW, 400V, 8.8A, 1440rmp/min, 50Hz, and
the load is disconnected. When F800=1, the operation steps are as following:
F801=3.7 F802=
380
F803=8.8 F805=
1440
F810= 50
F800=1
