Carrier Frequency Proportional Gain
0 to 99 <1>
<1> This setting is only enabled when C6-00=0.
□ Setting a Fixed Carrier Frequency
C6-01 can be adjusted within the setting range when C6-00 is set to 0.
Set the same value in C6-01 and C6-02 in control methods other than V/F Control.
□ Setting a Variable Carrier Frequency (Only for V/F Control)
In V/F Control, the carrier frequency can be set up to change linearly with the output frequency
by setting C6-01, C6-02 and C6-03 as shown in Figure 6.33.

Note:
1. When C6-03＞27 and C6-01＜ C6-02 , the carrier frequency will be fixed to the value set to C6-01.
2. When C6-03＜7, C6-02 is disabled and the carrier frequency will be fixed to the value set to C6-01.

□ Carrier Frequency Changes Based on Rated Current
According to carrier frequency settings, the drive rated output current changes as shown in
Table 6.11. The carrier frequency changes linearly with output current. Refer to Table 6.11 to
calculate the value if it is not specified.
