Multiple Rating Setting - Mitsubishi Electric FR-E800 Series Instruction Manual

8.9

Multiple rating setting

Two rating types of different rated current and permissible load can be selected. The optimal inverter rating can be selected
according to the application, enabling equipment to be downsized.

 Changing the parameter initial values and setting ranges
• When inverter reset and all parameter clear are performed after setting Pr.570, the parameter initial values are changed
according to each rating, as shown below.
