ST130 | Whistling noises from the engine – What can I do?

If the motor makes whistling noises or tends to vibrate when using a frequency converter, this may be due to the carrier frequency of the converter.

Solution:
Adapt the carrier frequency of the output current generation to the application of the motor. To do this, change parameter F0.07 to 15kHz.

Further details and a table with key data for correct selection of the carrier frequency can be found in the operating instructions in the extended section. If these settings do not solve the problem, please contact Sourcetronic Support.
