Offline auto tuning (Pr. 80 to Pr. 96)
3.12.5 Setting the motor constants directly
Offline auto tuning is not used.
The Pr. 92 and Pr. 93 motor constants may either be entered in [
The Pr. 92 and Pr. 93 motor constants may either be entered in [
Ω] or in [mH]. Before starting operation, confirm
which motor constant unit is used

1. After checking that the input motor constants are those for star connection or delta connection, set the Pr. 71
value as indicated below (When direct input is selected and offline auto tuning is performed, set "7, 8, 17 or 18")
in Pr. 71. (Refer to page 125.).

2. Set "801" in Pr. 77.
(The parameter values of the motor constants (Pr. 90 to Pr. 94) can be displayed. Though the parameter values
of other than Pr. 90 to Pr. 94 can also be displayed, they are parameters for manufacturer setting and their
values should not be changed.)

3. In the parameter setting mode, read the following parameters and set desired values.
4. Return the Pr. 77 setting to the original value.
5. Set Pr. 83 and Pr. 84.
5. Set Pr. 83 and Pr. 84.

1. Set "9999" in Pr. 90 to Pr. 94 to use the standard motor constants (including those for the constant-
torque motor).
2. If "star connection" is mistaken for "delta connection" or vice versa during setting of Pr. 71, control
cannot be exercised properly.
