PARAMETERS
(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.

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
× 1.05 = 2641.8, in Pr. 90 .
(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.)
