Hello Analog Device support team,

I am Hieu Nong, software engineer from METRAN Viet Nam.

Our company operates in the field of research and production of ventilators, especially the
production of high-frequency ventilators. Currently, the product is almost complete, but there is
currently a problem related to the use of a stepping motor driver to create oscillation

The problem we encounter is that the motor makes a lot of noise when operating, which is very
unacceptable for our products.
I have also configured the driver to reduce noise, but when the noise is reduced, the motor's
movement does not follow the desired sinusoidal motion. Please see the attached file for detail.

We very look forward to your help,

Best Regards,

 Metran Viet Nam,

R&D dept,
