14.1.4 Motor constants selection
•
When PM dive, adjust the motor constant settings to the motor to be driven by the inverter.
•
You can select the motor constants from the following three types:
(1) Motor constants of Hitachi standard motor
⇒
When 00 is set on PM motor code setting (H102), motor constants use (H106~H110). Initial values
of (H106~H110) are set on motor constants of Hitachi standard motor.
(2) Motor constants tuned by offline auto-tuning
⇒
When 01 is set on PM motor code setting (H102) after the offline auto-tuning allows, motor
constants use automatically measure values (H111~H113) and Hitachi standard motor values
(H109~H110).
(3) Arbitrarily set motor constants
⇒
In above-mentioned both (1) and (2) cases, motor constants can be changed to the given value.
Please change the value of (H106~H113) in the value of (H102).
