Multiple rating setting
Changeover of 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 follows.
Five rating types of different rated current and permissible load are available. The optimal inverter rating can be chosen
in accordance with the application, enabling equipment size to be reduced.
As well as the ratings of the FR-A800 standard type inverters, the SND rating is available for the FR-A800-R2R series.
