than 100 meters.
 C6-01/ C6-02/ C6-03 Maximum / Minimum Carrier Frequency / Carrier Frequency
Proportional Gain
Set 0 to parameter C6-00 to enable this setting. Sets the maximum and minimum carrier
frequency in V/F Control that the drive will adjust carrier frequency according to the output
frequency.

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.
