Check/record constants.
END
*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
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 factory setting of A1-02 (Control method selection) is 0
(V/f control).
*6 If the maximum output frequency is different from the base
frequency, set the maximum output frequency (E1-04) to the
value of the base frequency after autotuning.
