*2
*1 Set for 400 V Class Inverter for 55 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
whenever it is okay for the motor to be operated.
*4 If the motor cable changes to 50 m or longer for the actual
installation, perform stationary autotuning for the line-to-line
resistance only on-site.
*5 The default control mode is open-loop vector control 2
(A1-02 = 2).

*6 If the maximum output frequency and base frequency
are different, set the maximum output frequency (E1-
04) after autotuning.
