232 YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Note:
When the wiring length for bypass models B001 to B007 is more than 10 m, you must decrease the carrier frequency or output current.

C6-03: Carrier Frequency Upper Limit
No.

Name Description
Default
(Range)
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 - 12.5 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 .
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
Set C6-03 , C6-04 , and C6-05 [Carrier Freq Proportional Gain] as shown in Figure 5.31 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 .
• If these conditions are true at the same time, the drive will detect oPE11 [Carrier Frequency Setting Error] :
– C6-05 ≥ 6
–
C6-04 ≥ C6-03

C6-04: Carrier Frequency Lower Limit

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 - 12.5 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:
If these conditions are true at the same time, the drive will detect oPE11 [Carrier Frequency Setting Error] :
• C6-04 ≥ C6-03
• C6-05 ≥ 6

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.

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.
