Video: Different Servo Loop Control Schemes, Drives with Fieldbus vs Motionbus

This video tutorial explains different servo motor control schemes:

  • Torque loop (commutation loop)
  • Velocity loop
  • Position loop

Also explained:

  • What's a drive controller?
  • Drives with fieldbus such as DeviceNet, ProfiBus, CANopen
  • Drives with motionbus such as EtherCAT, Ethernet Powerlink (EPL), ProfiNet
