Multiple Rating Setting - Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual

5.7.11 Multiple rating setting

Four rating types of different rated current and permissible load can be selected. The optimal inverter rating can be chosen in
accordance with the application, enabling equipment size to be reduced.

*1 Not compatible with the IP55 compatible model.
 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.
