Editing Parameter Settings - Mitsubishi Electric FR-A800 Series Beginner's Manual

Editing parameter settings

5.4 Editing parameter settings
All the settings for the operation of frequency inverters are stored in editable parameters. You can find
a detailed reference to the most important parameters in chapter 6. All the parameters are preset to
default values when the inverter leaves the factory. You can edit parameters on the parameter unit to
configure the inverter for the connected motor and your application.
Note that editing parameters is only possible when the inverter is in PU operation mode (PU) or com-
bined mode and when no motor start (FWD or REV) command is active.
