* 1. The factory setting depends on the Inverter capacity. The value for a 200 V Class Inverter of 0.4 kW is given.
* 2. If a current exceeding 110% of the Inverter rated current flows through the unit, the carrier frequency will automatically decrease and electromagnetic
noise will occur.
* 3. The lower limits are 0.4 kHz for V/f control and 1.0 kHz for flux vector control. The upper limit is the same value as that of the factory setting for L8-
39.
