Current (Torque)

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

ADVANCED Motion Controls' Capabilities

  • All drives have current feedback
  • DigiFlex® Performance servo drives sample current at the switching frequency
  • typically 50 ms
  • AxCent servo drives sample the current loop continuously
