Note: 1. Indicates the parameter settings which are ignored when the advanced magnetic flux vector control mode is selected.

2.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.)

3.Can be set when Pr. 80, 81 ≠ 9999, Pr. 60 = 7 or 8.

4.Can be accessed when Pr. 80, 81 ≠ 9999, Pr. 77 = 801.

5.Can be accessed when Pr. 270 = 1 or 3, Pr. 80, 81 ≠ 9999.

6.The setting range and min. setting unit will differ according to the Pr. 71 "applied motor" setting value.

7.Can be accessed when Pr. 29 = 3.

8.Parameters marked asterisk (*) on top are different setting range, factory setting or function from FR-A540L.

9.Page numbers correspond to A540/A560L instruction manual, IB07401-0x.
