Description
The sensing device of the SSI is a 24-bit absolute multiturn encoder. The position
information is given by an analog/digital converter output serialized as a data word. The
processing unit (PLC, Microcomputer) sends pulse sequences which clocks the data
transmission at the required transfer rate. With the first falling edge of the pulse sequence
the position of the sensor is recorded and stored. The following rising edges control the
bit-by-bit transmission of the data word. After a delay time the next new position information

The sensing device of the SSI is a 25-bit absolute multiturn encoder. The position
