Before operation
4.3 Before operation
4.3.1 Simple mode 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). For details of parameters, refer to Chapter 4 of the Instruction
Manual (Applied).
POINT
Only simple mode parameter can be displayed using Pr.160 User group read selection. (All parameters are displayed
with the initial setting.) Set Pr. 160 User group read selection as required. (Refer to page 52 for parameter change.)
Pr. 160 Description
