A servo system essentially comprises an intelligent servo drive and a servo motor that operates with a PLC or CNC to perform complex, specialized moves in one or more directions, or axes. These complex and specialized moves, which are needed in the automation of industrial tasks, are collectively known as motion control. Servo systems are applied in many different field for automation – in the motor industry, the petrol industry, the textile industry, in packaging systems, warehousing systems and so on.

In a servo system, feedback information – motor position and motor velocity is sent from the feedback unit of the motor back to the servo amplifier. The servo amplifier analyses the feedback, makes adjustments as needed, and generates new currents to bring the motor to the commanded velocity. This cycle constantly repeats itself in a closed loop. A closed loop that controls the position of the shaft or load is called a position loop. A closed loop that keeps the velocity of the motor on the commanded value is called a velocity loop.

A servo motor moves machinery in a single axis of motion. Electrical motors are driven by magnetic fields. Motors have a stationary field generated by the magnets of the motor and a rotating or movable field called stator winding or armature. They operate on the principles of synchronous motors. All rotary motors have some type of bearing that supports the rotor at each end. Every motor has at least two magnetic motor poles, normally four or six.

The servo amplifier generates the current in the stator so that a controllable torque is available at the shaft. The servo motors turn (travel) in two directions – positive and negative. Two forms of angular measurement are commonly used in motion control – degree measurement and radian measurement, where 360 degrees constitute one revolution or 2
radians. The servo amplifier operates with standard synchronous servo motors as well as with direct drive motors (rotary or linear). For more information about these motors see the motor manuals.

Motor Stabilizing

Stabilizing (tuning) the motor is a fundamental task in achieving best system performance. To stabilize a motor, you must set up initial values for and adjust several motion parameters using DRIVE.EXE. These parameter settings compensate for the difference between the actual motion and the commanded motion – getting the actual as close to the commanded as possible, with minimal oscillation and noise. This difference is called following error
