The DM5 Decoder
Principle of Operation
The DM5 series resolver decoder provides an absolute encoder system in conjunction with any one of the AVG Automation's single-turn resolvers. As shown in the diagram on the next page, the resolver rotor winding is excited from a reference sinusoidal generator inside the DM5 unit. The analog output signals from the resolver stator windings, after signal condi-tioning in the buffer amplifiers, are decoded to digital format in the Ratiometric Tracking Converter. The zero offset, set by the front panel thumbwheels, is continuously added to this value and the resultant position is displayed on the front panel of the unit. The position information is also made available in a parallel format for external devices, such as PLCs, remote displays etc.
