NOTES
When "9999" is set in Pr. 82, Pr. 90 to Pr. 94, Pr. 859, 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 addition of a
given value to the displayed value has no significance.)
