C6-03
(0225)
Carrier Frequency Upper
Limit
Sets the upper limit of the carrier frequency. Set C6-02 = F [Carrier Frequency Selection = User
Defined (C6-03 to C6-05)] to set this parameter.
Determined by C6-02
(1.0 - 15.0 kHz)
Setting a Fixed User-Defined Carrier Frequency
When you cannot use C6-02 to set a carrier frequency between set selectable values, you can set the value in C6-
03
. The carrier frequency will be fixed to the value set to
C6-03
.
When A1-02 = 0, 1 [Control Method Selection = V/f, CL-V/f] , set C6-03 = C6-04 [Carrier Frequency Lower
Limit] to fix the carrier frequency.
Setting a Variable Carrier Frequency to Agree with the Output Frequency
When
A1-02 = 0, 1
, set
C6-03
,
C6-04
, and
C6-05 [Carrier Freq Proportional Gain]
as shown in Figure 11.40 to
make the carrier frequency change linearly with the output frequency.

Note:
• When C6-05 ≤ 7 , the drive disables C6-04 . The carrier frequency is fixed to the value set to C6-03 .
• The drive detects oPE11 [Carrier Frequency Setting Error] when these conditions are correct at the same time:
– C6-05 ≥ 6
– C6-04 ≥ C6-03

C6-04
(0226)
Carrier Frequency Lower
Limit
Sets the lower limit of the carrier frequency. Set C6-02 = F [Carrier Frequency Selection = User
Defined (C6-03 to C6-05)] to set this parameter.
Determined by C6-02
(1.0 - 15.0 kHz)
Set
C6-03 [Carrier Frequency Upper Limit]
,
C6-04
, and
C6-05 [Carrier Freq Proportional Gain]
to make the
carrier frequency change linearly with the output frequency.
Note:
The drive detects oPE11 [Carrier Frequency Setting Error] when these conditions are correct at the same time:
• C6-04 ≥ C6-03
•
C6-05 ≥ 6

Carrier Freq Proportional
Gain
Sets the proportional gain for the carrier frequency. Set C6-02 = F [Carrier Frequency Selection
= User Defined (C6-03 to C6-05)]
to set this parameter.

(0 - 99)
Set C6-03 [Carrier Frequency Upper Limit] , C6-04 [Carrier Frequency Lower Limit] , and C6-05 to make the
carrier frequency change linearly with the output frequency.
