Analog to digital signal converter for resolver / encoder / SSI / Inductosyn

In many cases, the feedback generated by a motor is not the type of feedback format required for the servo drive. For such cases MACCON offers different types of signal converters to convert from analog formats (e.g. resolver) to digital formats (SSI, Quad A/B/Z).

It might also be the case, that we need to convert a digital absolute format (e.g. SSI) to a digital incremental format (Quad A/B/Z).

In this sector we offer several product lines of our partner company VEGA.

To convert the analog signal output of your resolvers into a digital signal, you need a converter. MACCON offers a selection of efficient components designed to output the digital square wave signals commonly found in encoders. In essence, our converters allow you to create digital resolvers that combine the robustness of a resolver with the digital simplicity of an encoder. This is ideal for industrial automation situations where you need to detect the rotational position of your devices but do not want to deal with the required installation of the sensors.

Improving Motion Control

Using the digital signal from an encoder makes it easier to work with the output data to understand the position and speed of your equipment.
Digital signals are also easier to send to other devices without the need for further processing or external analog-to-digital converters.
