Figure 5.39 Carrier Frequency Changes Relative to Output Frequency
Note: 1. C6-03 takes priority when the carrier frequency proportional gain C6-05 > 27 and C6-03 < C6-04.
2. When C6-05 is set lower than 7, C6-04 is disabled and the carrier frequency will be fixed to the value set in C6-03.

C6-09: Carrier Frequency during Rotational Auto-Tuning
Determines the carrier frequency while performing Rotational Auto-Tuning. Although this parameter rarely needs to be
changed, when overcurrent problems occur when Auto-Tuning a high frequency motor or low impedance motor, it may be
helpful to set C6-03 to a high value before setting C6-09 to 1.

Rated Current Depending on Carrier Frequency
The table below shows the drive output current depending on the carrier frequency settings.
Normal Duty Rating (ND)
The 2 kHz values shown for ND in Table 5.16 are equal to the drive rated current shown on the drive nameplate. Increasing
the carrier frequency above 2 kHz will reduce the ND rated output current of the drive as shown in Table 5.16.
Heavy Duty Rating (HD)
A carrier frequency setting of 8 kHz or lower is equal to the drive rated current shown on the drive nameplate. The factory
default setting for carrier frequency in HD mode is 2 kHz. Increasing the carrier frequency above 8 kHz will reduce the HD
rated output current of the drive as shown in Table 5.16.
Use the data in Table 5.16 to linearly calculate output current values for carrier frequencies not listed.
