Carrier Frequency Selection

Sets the carrier frequency for the transistors in the drive.

1
2.0 kHz
 
2
5.0 kHz (AOLV/PM: 4.0 kHz)
 
3
8.0 kHz (AOLV/PM: 6.0 kHz)
 
4
10.0 kHz (AOLV/PM: 8.0 kHz)
 
5
12.5 kHz (AOLV/PM: 10.0 kHz)
 
6
15.0 kHz (AOLV/PM: 12.0 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

Set this when the wiring distance between the drive and motor is long and there is a fault in the current monitor or the drive detects and alarm because of the effect of a leakage current.

The carrier frequency is equivalent to 2.0 kHz.

F
User Defined (C6-03 to C6-05)

Use C6-03 to C6-05 to set detailed setting values.

Note:

  • The setting range changes when the A1-02 [Control Method Selection] value changes:

    • 5, 8 [OLV/PM, EZOLV]: You can set C6-02 = 1 to 6, B, and F.

    • 6 [AOLV/PM]: You can set C6-02 = 1 to 6.

  • 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

Carrier Freq at Rotational Tune

Sets the Auto-Tuning carrier frequency. Usually it is not necessary to change this setting.

0
5 kHz
Note:

When A1-02 = 5 or 6 [Control Method Selection = OLV/PM or AOLV/PM], the carrier frequency is 2 kHz.

1
Use C6-03
Note:

When A1-02 = 5 or 6, the carrier frequency is the value set to C6-02.
