Note: 1. Indicates the parameter settings which are ignored when the advanced magnetic flux vector
control mode is selected.
2. The factory setting of the FR-A540 (400V class) is 400V.
3. Can be set when Pr. 80, Pr. 81 ≠ 9999, Pr. 60 = 7 or 8.
4. Can be accessed when Pr. 80, Pr. 81 ≠ 9999, Pr. 77 = 801.
5. Can be accessed when Pr. 270 = 1 or 3, Pr. 80, Pr. 81 ≠ 9999.
6. The setting depends on the inverter capacity.
7. Can be accessed when Pr. 29 = 3.
8. The half-tone screened parameters allow their settings to be changed during operation if 0
(factory setting) has been set in Pr. 77. (Note that the Pr. 72 and Pr. 240 settings cannot be
changed during external operation.)
9. The setting depends on the inverter capacity: (0.4K)/(1.5K to 3.7K)/(5.5K, 7.5K)/(11K).
10. The setting depends on the inverter capacity: (0.4K to 1.5K)/(2.2K to 7.5K)/(11K or more).
