Setting method of the motor constants of the SF-HR type high efficiency motor and SF-
HRCA type inverter drive dedicated constant torque motor.
• When offline auto tuning is enabled with motor running
1) Set Pr. 9 "electoronic thermal O/L relay", Pr. 80 "motor capacity", Pr. 81 "number of motor poles", Pr. 83
"rated motor voltage" and Pr. 84 "rated motor frequency" according to the motor.
2) Set "13" in Pr. 71. (offline auto tunning selection of constant torque motor)
3) Set "101" in Pr. 96 and perform offline auto tuning with motor running.
4) After completion of auto tuning, set "1" in Pr. 95.
5) Set "14" in Pr. 71 and "801" in Pr. 77.
6) Set the values in the following table in Pr. 85, Pr. 86 and Pr. 89.
7) Return the Pr. 77 setting to the original value.
• When offline auto tuning is not enabled
(When the inverter capacity and the motor capacity are same)
1) Set Pr. 9 "electoronic thermal O/L relay", Pr. 80 "motor capacity", Pr. 81 "number of motor poles", Pr. 83
"rated motor voltage" and Pr. 84 "rated motor frequency" according to the motor.
2) Set "14" in Pr. 71 and "801" in Pr. 77.
3) Set the values in the following table in Pr. 85, Pr. 86 Pr. 89, Pr. 82, Pr. 90 to Pr. 94.
4) Set "1" in Pr. 95.
6) Return the Pr. 77 setting to the original value.
(Note) Though other parameter values can also be displayed when "801" is set in Pr. 77, they are
parameters for manufacturer setting and their values should not be changed. Note that changing
the settings may damage the inverter.
