Ultract II Standard Sinusoidal Encoder Specifications |

Sensor evolution: from digital encoders to infinite resolution |
||
|
The new generation of 6 track sinusoidal encoders overcomes the traditional resolution limitations of resolvers and digital encoders. The encoder signal, suitably processed by the drive, is absolute from start-up within the mechanical revolution. The absolute signal is obtained by processing the one cycle/rev tracks; after 1 revolution, the high resolution index pulse is sensed and synchronized with the slow track reading to attain a maximum accuracy. The resolution attainable with the fast tracks, useful at low speed and in positioning, (2048 cycles/rev which can be intrerpolated) is virtually unlimited. Consequently, excellent low speed servo performance and homogeneous rotation can be achieved. The traditional limits of digital sensors are overcome and irmovative control strategies, such as acceleration loop control, are possible. The standard encoder accuracy is 20”.
