■ Carrier Frequency Selection (C6-02)
Fixed Carrier Frequencies
The carrier frequency can be set using parameter C6-02 as shown in table below.
Use the following guideline to set up the carrier frequency:

TERMS
Swing PWM uses low carrier frequency but by applying special PWM patterns
the audible noise of the motor is kept low.
Symptom Remedy
Speed and torque are unstable at low speeds.
Lower the carrier frequency.
Noise from the drive is affecting peripheral devices.
Excessive leakage current from the drive.
Wiring between the drive and motor is too long.
<1>
<1> The carrier frequency may need to be lowered if the motor cable is too long. Refer to the table
below.
Motor acoustic noise is too loud. Increase the carrier frequency or use Swing PWM.
Wiring Distance Up to 50 m Up to 100 m Greater than 100 m
