+ The rated current indicated on the nameplate of a 15kW inverter or smaller is the current that flows at 4kHz. If the
carrier frequency is set at 12kHz by default, therefore, the rated current needs to be decreased.
⇒ For more details, refer to Section 12.
When H=, however, the carrier frequency decreases automatically with increase in current to secure the
rated current for frequencies below 4kHz.
+Random control is exercised when the motor is operated in a low-frequency range where it produces annoying
magnetic noise.
+ If the carrier frequency control mode selection parameter (H) is set to or , the output voltage may drop.
The carrier frequency (EH) should be set below 4kHz.
