I am working on monitoring research. During it I found a lot of papers use Hall effect sensors to get spindle current. However some of them are accessed internally to spindle driver current. I will be thankful if any cnc professional can guide me how to access internally to spindle current and which types of cnc have this ability?

  • $\begingroup$ Most modern industrial CNC controllers have spindle load monitors. That might be a starting point for you $\endgroup$
