5.7.10 Multiple rating setting
 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.
 Initial values differ depending on the rating as follows.
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.
