Frequent and accurate current sampling is necessary to close the current loop, which is the foundation for a sound motion control system. Current feedback is also used for torque control since output torque is proportional to motor current.
- DigiFlex® Performance™ servo drives make it easy to tune a high performing current loop
- AxCent™ servo drives come with tuning that works well with most motors and applications
