3.3 Parameter Checking and Setting
The inverter is designed to perform simple variable-speed operation with the factory settings of the
parameters. Set the necessary parameters according to the load and operation specifications. Use the
operation panel (FR-DU04) to set, charge and confirm the parameter values. For full information on the
parameters, refer to “CHAPTER 4 PARAMETERS”(Page 62).
3.3.1 Parameter checking
Pr. 160 "user group read selection" is factory-set to display only the simple mode parameters among the
parameters. Set the following parameters as required.
