The use of this module in conjunction with a SSI encoder provides direct positional information rather than the type of data resultant from incremental type encoders. Absolute encoders are comprised of several data disks which generate a data

word which is unique through out the 360 degrees of rotation. The data format is a modified binary pattern in either Graycode or Dualcode.

The resolution of the sensor depends upon the configuration of the sensor and the physical number of revolutions in the motion profile. Since the basis of the encoder is to provide absolute positional information based upon a mechanical configuration limited to one revolution or less. The maximum resolution of this module is 24 bit.

The frequency of the data signal input to the SSI module is maintained at 125 kHz. Listed below are the recommended cable lengths for the various clock signal Baud rates.

Quadrature Encoder Interface

PN 750-631, 750-631/000-001

Technical Description:

This technical description is only valid for hardware and software versions X X X X 2 B 0 1----. The product series number is printed on the right side of the module.

The described operational mode is 4 times or quadrature sampling.

The following description is preliminary and is applicable to the factory configuration.

Attention:

The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)! A module which needs all contacts (e.g. 2 channel digital) may not be connected to the right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel modules).

The Quadrature Encoder Interface is able to run with all WAGOÇI/OÇSYSTEM buscouplers (except for the economy type).
