(4) Utilizing or changing offline auto tuning data for use
The data measured in the offline auto tuning can be read and utilized or changed.
<Operating procedure>
1)Set Pr. 71 according to the motor used.

*1 For other settings of Pr. 71, refer to page 187.
2)In the parameter setting mode, read the following parameters and set desired values.

82 Motor excitation current
90 Motor constant (R1)
91 Motor constant (R2)
92 Motor constant (L1)
93 Motor constant (L2)
94 Motor constant (X)
859 Torque current
REMARKS
· The display units of the motor constants read using Pr. 684 Tuning data unit switchover can be changed. Note that parameter
values cannot be changed.

· When "9999" is set in Pr. 82, Pr. 90 to Pr. 94, Pr. 455, Pr. 458 to Pr. 462, Pr. 859, Pr. 860, Mitsubishi motor (SF-JR, SF-HR, SF-
JRCA, SF-HRCA, SF-V5RU (1500r/min series), etc.) 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 "2516",
set 2642, i.e. 2516
(The value displayed has been converted into a value for internal use. Hence, simple addition of a given
value to the displayed value has no significance.)
