1. Set for 400 V Class Inverter for 75 kW or more.
2. If there is a reduction gear between the motor and PG, set the
reduction ratio in F1-12 and F1-13 in advanced programming
mode.
3. Use rotational autotuning to increase autotuning accuracy when-
ever it is okay for the motor to be operated.
4. If the motor cable changes to 50 m or longer for the actual instal-
lation, perform non-rotating autotuning for the line-to-line resis-
tance only on site.
5. The default control mode is Open Loop Vector control
(A1-02=2).
6. If the maximum output frequency and the base frequency are dif-
ferent, set the maximum output frequency (E1-04) after autotun-
ing.
