Multiple Rating Setting - Mitsubishi Electric 800 Series Instruction Manual

7.6

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.
Pr. Name
570
Multiple rating setting
E301
 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.

*2 The rated current and motor capacity values differ depending on the inverter capacity. Refer to the inverter rated specifications in the Instruction
Manual (Connection).
*3 The initial value for the FR-E820-0050(0.75K) or lower, the FR-E840-0026(0.75K) or lower, and the FR-E860-0017(0.75K) is set to the 85% of
the inverter rated current.
