C6 Carrier Frequency
 C6-00 Carrier Frequency Selection
Sets the switching frequency of the drive output transistors. Adjust this setting to reduce
audible noise and leakage current.
Note:
1. If this level is set higher than the default setting, the drive rated current will be decreased.

Setting Carrier Frequency
Situation
Solution
Speed and torque fluctuate at low speeds
Lower the carrier frequency
The drive noise affects peripheral devices
Excessive leakage current from the drive
Cable connecting the drive and motor is too
long<1>
Loud noise from the motor
Increase the carrier frequency <2>
<1> If the cable is too long, lower the carrier frequency according to the follow instructions.

Note: In PM Open-Loop Vector ControlP (A1-02=5), make sure the cable connecting the drive and motor is less
than 100 meters.
 C6-01/ C6-02/ C6-03 Maximum / Minimum Carrier Frequency / Carrier Frequency
Proportional Gain
Set 0 to parameter C6-00 to enable this setting. Sets the maximum and minimum carrier
frequency in V/F Control that the drive will adjust carrier frequency according to the output
