Analog actuators

Overview of our analog servo drives

   Easy to implement actuators for absolute positioning with analog output.

Functioning and design of analog actuators

AG01 and AG02 positioning drives in detail

   With the DriveLine AG01 and AG02 analog actuator / spindle drive, potentiometer sensors are used as sensors for recording angle change or rotation direction and in conjunction with mechanical units such as spindles, synchronous belts or gear racks for recording linear movements.

   The potentiometer-encoder is a position sensor of the potentiometer type. Based on the position of the movable part (slider), the electrical resistance between the slider and the ends changes. By switching the encoder as a voltage divider, it is thus possible to obtain an electrical voltage that changes relative to the position. Using transmitters (analog), also referred to as measuring transducers in some areas, the resistance values can be provided or emitted in a standardized, analog electrical standard signal, for example electrical signals in accordance with DIN IEC 60381-1: 0 to 20 mA or 4 to 20 mA (live zero) or voltage signals in accordance with DIN IEC 60381-2: 0 to 10 V or 2 to 10 V (live zero). Live-zero signals are used in almost all industrial applications. If the beginning of the measurement area is allocated an electrical signal that differs from 0, it is possible to monitor breaks in the wire. The process of recording measurement values is adjusted to the entire measurement range using an internal measuring gear as well as a trimmer potentiometer in the case of transformers.

   Unlike a digital signal, an analog signal is stepless and can be as fine as needed. In the case of real physical parameters, however, the resolution is limited by disruptions such as noise or distortion. Once disruptions are added to an analog signal, they can no longer be reversed.

   Modern rotary potentiometers are manufactured with tracks made from conductive plastic. Not only does this solution ensure a considerably longer service life than a wire potentiometer, the high-quality mixtures also make it possible to use the products even in moist conditions or at high temperatures.

Analog actuators with integrated absolute measurement technology

   By using absolute encoders with an analog output signal, these do not have to be referenced after switching on (unlike incremental encoder systems), as changes in position are recorded when the device is switched off and are available immediately after switching on the device.

   Up to 1,280 revolutions of the motor gear drive shaft with an analog signal of 10kOhm or 0 - 10V as well as 4 - 20mA are standard for the AG01 and AG02 range. The large measurement area achieved as a result means that even long linear distances can be positioned absolutely and very precisely.

Areas of application of analog actuators

   In an industrial environment, DriveLine drives / actuators with an analog output are often used for automated format adjustment, stops, tools and valves or fittings as well as for many other comparable positioning tasks, in general and special machine construction, in assembly technology, handling technology, robot technology and on or in trade fair equipment and testing equipment as well as in process automation.
