Selection and protection of a motor
Utilizing or changing offline auto tuning data for use
The data measured in the offline auto tuning can be read and utilized or changed.
Set Pr. 71 according to the motor used:
Motor
Mitsubishi standard motor,
Mitsubishi high efficiency motor
Mitsubishi constant-torque motor
Other manufacturer's standard motor
Other manufacturer's constant-torque motor
Tab. 6-16: Motor selection
For other settings of Pr. 71, refer to section 6.8.2.
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.
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.)
