Selection and protection of a motor
(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.
Mitsubishi standard motor
Mitsubishi high efficiency motor
Mitsubishi constant-torque motor
Other manufacturer's
standard motor
Other manufacturer's
constant-torque motor
∗1
For other settings of Pr.71, refer to page 111.
2) In the parameter setting mode, read the following parameters and set desired values.
Parameter
Number
82 Motor excitation current
90 Motor constant (R1)
91 Motor constant (R2)
92 Motor constant (L1)
93 Motor constant (L2)
94 Motor constant (X)
859 Torque current
REMARKS
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:

When Pr. 90 is displayed as "2516",
set 2642, i.e. 2516 x 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.)
