991 Parameter unit parameters Refer to the parameter unit instruction manual for details.
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 r ange 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, f actory setting or function from
FR-A540L.
9. Page numbers correspond to A540/A560L instruction manual, IB07401-0x.
