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.
