WS Position SensorsOutput Specification ADSI

The sensing device of the ADSI is a precision potentiometer. The position information isgiven by an analog/digital converter output serialized as a data word. Data transmissiontakes place by means of the signals CLOCK and DATA. The processing unit (PLC, Micro-computer) sends pulse sequences which clock the data transmission with the requiredtransfer rate. With the first falling edge of a pulse sequence the position of the sensor isrecorded and stored. The following rising edges control the bit-by-bit A/D conversion,encoding and output of the data word.After a delay time the next new position information will be transmitted.

The sensing device of the SSI is a 25-bit absolute multiturn encoder. The positioninformation is given by an analog/digital converter as a serial data word. The processing unit(PLC, Microcomputer) sends pulse sequences which clocks the data transmission at therequired transfer rate. With the first falling edge of the pulse sequence the position of thesensor is recorded and stored. The following rising edges control the bit-by-bit transmissionof the data word. After a delay time the next new position information will be transmitted.
