Note For each parameter in the above table, the values enclosed in parentheses ( ) represent the setting range/default data
for high-capacity type (75 to 132 kW) inverters.
Without parentheses ( ), the parameter has the same setting range/default data regardless of the inverter capacity.

*1. Conversion: The current value will be converted at the ratio of the rated current for the heavy load/light load mode.
(Example) If you change from a light load mode setting of 5 A (rated current: 10 A) to the heavy load mode
(rated current: 8 A), the current value will be converted as follows: Rated current 8A x 50% (5 A/10
A) = 4 A.
