(1) Inverter-generated heat
When the rated output current flows, the inverter
generates heat as shown on the preceding page.
1) Reduction according to motor load factor
At the rated output current, the following figure
shows a reduction rate when operating the
inverter with a light load.
2) Reduction according to duty
The ratio of reduction during intermittent operation
in a cycle of within five minutes is shown.
