[Selection 2: Setting vector control and manual tuning independently]

If an "GVP" tuning error is displayed during auto-tuning or when vector control characteristics are to be
improved, independent motor constants can be set.

Setting procedure Adjust the following parameters:

H

: Set the compensation gain for the slipping of the motor. A higher slip frequency reduces motor

slipping correspondingly. After setting H, set H to adjust in detail.

H

: Adjust the primary resistive component of the motor. Use the auto-tuning value.

H

: Set the rated current of the motor. For the rated current, see the motor's nameplate or test report.

H

: Set the ratio of the no-load current of the motor to the rated current. Enter the value in % that is

obtained by dividing the no-load current specified in the motor's test report by the rated current.

H

: Set the rated rotational speed of the motor. For the rated current, see the motor's nameplate or test

report.
