*The currents in the above figure are used as the basis to make calculations for inverter overload trip (QN).
*If H is set to or , QER trip will occur when the current increases and reaches the level above which the carrier frequency is decreased automatically.
*Random control is exercised when the motor is operated in a
If the carrier frequency (H) is set above 7.1 kHz, the random control function will not be performed, because the level of motor magnetic noise is low at high frequencies.
*When the carrier frequency control mode selection (H) is set to or , the carrier frequency (H) should be set preferably 6 kHz. Otherwise the output voltage may drop.
