Utilizing or changing offline auto tuning data for use
The data measured in the offline auto tuning can be read and utilized or changed.
Set Pr. 71 according to the motor used.:
For other settings of Pr. 71, refer to section 6.12.2.
In the parameter setting mode, read the following parameters and set desired values.

NOTES The display units of the motor constants read using Pr. 684 Tuning data unit switchover can
be changed. Note that parameter values can not be changed.
When "9999" is set in Pr. 90 to Pr. 94 , Mitsubishi motor (SF-JR, SF-HR,SF-JRCA, SF-HRCA)
constants are used.
As the motor constants measured in the offline auto tuning have been converted into internal
data (****), refer to the following setting example when making setting:
Setting example:
To slightly increase Pr. 90 value (5%)
When Pr. 90 is displayed as "2516", set 2642, i.e. 2516 × 1.05 = 2641.8, in Pr. 90.
(The value displayed has been converted into a value for internal use. Hence, simple addi-
tion of a given value to the displayed value has no significance.)
