Multiple Rating Setting - Mitsubishi Electric FR-A820-00046 Instruction Manual

Parameters
5.7.10

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.
Pr.
570

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.
