4.2 Parameter List

4.2.1 Parameter list
For simple variable-speed operation of the inverter, the initial setting of the parameters may be used as they are. Set the
necessary parameters to meet the load and operational specifications. Parameter setting, change and check can be made
from the operation panel (FR-DU07).
REMARKS
 
indicates simple mode parameters. (initially set to extended mode)

The shaded parameters in the table allow its setting to be changed during operation even if "0" (initial value) is set in Pr. 77 Parameter write
selection.

Refer to the Appendix 2 (page 472) for instruction codes for communication and availability of parameter clear, all clear, and parameter
copy of each parameter.

Parameters with have different specifications according to the date assembled. Refer to page
