Parameter
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 ]
Set Pr. 71 according to the motor used:
Standard motor
Constant-torque motor
Tab. 6-18: Setting of parameter 71
In the parameter setting mode, read the following parameters and set desired values.

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.
