Carrier Frequency
C6-03
C6-04
* K is the coefficient determined by the set value in C6-03.
To fix the carrier frequency, set C6-03 and C6-04 to the same value, or set C6-05 to 0.

C6-03 < C6-04.
Carrier Frequency and Current Derating
The default carrier frequency for the Normal Duty 1 mode depends on the inverter capacity. The overload
capability is 120% of the Normal Duty 1 rated current for 1 minute.
If the carrier frequency is set to a higher value than the factory setting, the overload capability is reduced like
shown in Fig 6.2.
