Method to set the motor constants without using the offline auto tuning data
The Pr. 90 to Pr. 94 motor constants may either be entered in [ , m ] or in [mH]. Before starting op-
eration, confirm which motor constant unit is used.
To enter the Pr. 90 to Pr. 94 motor constants in [ ]/[m ]

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.
If "star connection" is mistaken for "delta connection" or vice versa during setting of Pr. 71,
advanced magnetic flux vector control and general-purpose magnetic flux vector control cannot
be exercised properly.
