C6-02
(0224)
Carrier Frequency
Selection
Sets the carrier frequency for the transistors in the drive.
1 : 2.0 kHz
2 : 5.0 kHz (4.0 kHz for AOLV/PM)
3 : 8.0 kHz
4 : 10.0 kHz
5 : 12.5 kHz
6 : 15.0 kHz
7 : Swing PWM4 (Audible Sound 1)
8 : Swing PWM4 (Audible Sound 2)
9 : Swing PWM4 (Audible Sound 3)
A : Swing PWM4 (Audible Sound 4)
B : Leakage Current Rejection PWM
F : User Defined (C6-03 to C6-05)
Note:
• The setting range changes when the A1-02 [Control Method Selection] value
changes:
–5, 8 [OLV/PM, EZOLV]: You cannot set to 7 to A.
–When 6 [AOLV/PM]: 2 [5.0 kHz (AOLV/PM: 4.0 kHz)] is available.
• The carrier frequency for Swing PWM 1 is equivalent to 2.0 kHz. Swing PWM
applies a special PWM pattern to decrease the audible noise.
Determined by A1-02,
C6-01, and o2-04

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)

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)

(0227)
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.
