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).
