Before performing offline auto tuning
●
Make sure advanced magnetic flux vector control or general-purpose magnetic flux vector control
(Pr. 80, Pr. 81) is selected (refer to section 5.1.7). (Tuning can be performed even under V/F control
selected by turning on X18.)
●
A motor should be connected. Note that the motor should be at a stop at a tuning start.
●
The motor capacity should be equal to or one rank lower than the inverter capacity. (Note that
the capacity should be 0.1 kW or more.)
●
The maximum frequency is 120 Hz.
●
A high-slip motor, high-speed motor and special motor cannot be tuned.
●
As the motor may run slightly, fix the motor securely with a mechanical brake or make sure that
there will be no problem in safety if the motor runs (caution is required especially in elevator).
Note that tuning performance is unaffected even if the motor runs slightly.
Setting
햲
Select advanced magnetic flux vector control or general-purpose magnetic flux vector control.
(Refer to section 5.1.7.)
햳
Set "1" or "11" in Pr. 96 "Auto tuning setting/status".
– When the setting is "1":
Tune all motor constants without running the motor.
When performing advanced magnetic flux vector control, set "1" to perform tuning.
Depending on the motor type and the inverter capacity it takes approximately 25 to 75 s until
tuning is completed.
(Excitation noise is produced during tuning.)
– When the setting is "11":
Tune motor constants (R1) only without running the motor.
When performing general-purpose magnetic flux vector control, set "11" to perform tuning.
It takes approximately 9 s until tuning is completed.
햴
Set the rated motor current (initial value is rated inverter current) in Pr. 9 "Electronic thermal O/L
relay". (Refer to page 5-2.)
햵
Set the rated voltage of motor (initial value is 200 V) in Pr. 83 "Rated motor voltage" and rated
motor frequency (initial value is 60 Hz) in Pr. 84 "Rated motor frequency".
햶
Set Pr. 71 "Applied motor" according to the motor used.
햲
For other settings of Pr. 71, refer to the section 6.12.2.
