After the motor power F3.01 is changed, the drive sets the parameters F3.02~F3.10
as the motor parameters of corresponding power.
If the parameters of the motor are known, please write the values into F3.06 ~F3.10
accordingly. The real values of these parameters multiplied by the motor power are equal
to the set values of the parameters.
If the motor parameters are self-tuned, the set values of F3.06~F3.10 will be updated
after the self-tuning is completed normally.
F3.11
Parameter self-tuning
0~2
0
This function can automatically measure and write the parameters of the motor.
0: Parameter self-tuning is not available
1: Motor static setting
Before self-tuning, make sure to enter the nameplate parameters (F3.00~F3.05) of
the controlled motor correctly.
During static setting, the motor is in static state, in this case, the stator resistance (Rs),
rotor resistance (Rr) and stator leakage inductance (L) of the motor are automatically
measured, and the measured parameters are automatically written into F3.06, F3.07 and
F3.08 accordingly.
2. Motor rotation setting
During rotation setting, the motor is in static state first, in this case, the stator
resistance (Rs), rotor resistance (Rr) and stator leakage inductance (L) of the motor are
automatically measured; then the motor is in rotation state, the mutual inductance (Lm) and
no-load current (I0) of the motor are automatically measured, and the measured
parameters are automatically written into F3.06, F3.07, F3.08, F3.09 and F3.10
accordingly.
After self-tuning, the set value of F3.11 will be automatically set to 0.
Self-tuning steps
1. Correctly set functions "F3.04 basic operating frequency" and "F3.05 maximum
output voltage" according to the motor characteristics.
2. Correctly set the functions "F3.00 motor pole number", "F3.01 rated power" and
"F3.02 rated current".
3. Set F3.11 to 1 or 2, press the ENT key, and then press the RUN key to start
self-tuning.
4. When the run indicator on the LED operation panel lights off, it indicates the
self-tuning is completed.
