Slowest Possible Speed

What is the slowest speed possible for a direct drive using the ODrive S1 and M8325S motor through velocity control?

Hm. Really depends. With anticogging and good tuning, maybe down to 0.01 - 0.05 rev/s, maybe below. However, the noise of the S1’s onboard encoder will start to be significant, and make it more difficult to precisely regulate velocity, especially under varying load. Can I ask your application?

Thank you for the quick response, luckily the load will not be varying much. The motion profile is extremely similar to that of the second hand on an analog clock.
