PARAMETERS
Note: 1. Underlined parameter values are values changed from the factory settings.
2. The motor constants indicate the data measured in the offline auto tuning.
3. The Pr. 85 settings of "9999" (factory setting) and "10" are equal.
4. Wrong setting will provide an alarm output. Therefore, make sure that the settings are correct.
5. For the output is 0.2kW, set Pr. 80 "motor capacity " to 0.4 (kW).
• When offline auto tuning is not enabled
(When the inverter capacity is one rank higher than the motor capacity)
1) Set Pr. 9 "electoronic thermal O/L relay", Pr. 80 "motor capacity", Pr. 81 "number of motor poles", Pr. 83
"rated motor voltage" 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 table on the previous page in Pr. 85, Pr. 86, Pr. 89 and Pr. 94.
4) Calculate the Pr. 82 setting using the following calculation expression.
5) Calculate the Pr. 90 to Pr. 93 setting using the following calculation expression.
6) Set "1" in Pr. 95
7) Return the Pr. 77 setting to the original value.
(Note) When using the 0.4K inverter and the 0.2K motor, enter the values in the table on the previous page.
