10.3.4.2 Servo inverters

Servo inverters are highly dynamic current-controlled systems for speed, torque, or position control.

They are characterised by a high speed accuracy, a great torque setting range, and a high overload

capacity. For the operation a speed feedback is always required.

• Position-controlled systems are suitable for drive tasks as e.g. positioning, electronic gearbox or

electronic cam.
