<Operating procedure>
1. Set "801" in Pr. 77. Only when the Pr. 80 and Pr. 81 settings are other than "9999", the parameter
values of the motor constants (Pr. 90 to Pr. 94) can be displayed. Though the parameter (Pr. 82 to
Pr. 99) values of other than the motor constants (Pr. 90 to Pr. 94) can also be displayed, they are
parameters for manufacturer setting and should be handled carefully without misuse.
2. Set any of the following values in Pr. 71:
·
Standard motor...................................................................................... Pr. 71 = "0"
·
Constant-torque motor........................................................................... Pr. 71 = "1"
3. In the parameter setting mode, read the following parameters and set desired values:

90 Motor constant R1 0 to 50Ω, 9999 0.001Ω 9999
91 Motor constant R2 0 to 50Ω, 9999 0.001Ω 9999
92 Motor constant L1 0 to 1000mH, 9999 0.1mH 9999
93 Motor constant L2 0 to 1000mH, 9999 0.1mH 9999
94 Motor constant X 0 to 100%, 9999 0.1% 9999
4. Refer to the following table and set Pr. 84:

5. Return the Pr. 77 setting to the original value.
Note: 1. Pr.90 to Pr. 94 values may only be read when the Pr. 80 and Pr. 81 settings are other than
"9999" (advanced magnetic flux vector control selected).
2. Set "9999" in Pr. 90 to Pr. 94 to use the standard motor constants (including those for the
constant-torque motor).

z Online auto tuning selection (Pr. 95)
Pr. 95 "online auto tuning selection"
By online auto tuning, the motor conditions are tuned rapidly at the start. This enables precise operation
unaffected by motor temperatures and steady high-torque operation down to super-low speed. After setting
the Pr. 80 and Pr. 81 values, select online auto tuning with Pr. 95.
z Online auto tuning
Use this function when steady high-torque operation is required for low-speed operation under advanced
magnetic flux vector control.

Before starting the online auto tuning, perform the offline auto tuning. Data must be calculated.
