Caution
1) The above graph is only applied when the inverter is operated in the allowable temperature. Pay
attention to the air cooling when the inverter is installed in a panel box, and the inside temperature
should be within an allowable temperature range.
2) The output current value on the above graph is the proportion of inverter’s rated current; it is
applied to relative rated motor of the inverter.
