The EL5001-0011 SSI monitor EtherCAT Terminal is used for monitoring the data exchange between SSI master and SSI encoder (slave). The encoder is powered via the existing SSI interface. The interface circuit makes the incoming data stream available to the controller as a data word in the process image. Various operating modes can be permanently set via the control register.

The EL5001-0011 EtherCAT Terminal can be interconnected in an SSI master/slave communication. It is used for passive reading of the data exchange between SSI master and SSI slave (encoder). This enables the current position value to be made available to other control modules. The EL5001-0011 offers an optional 24 V encoder operating voltage.

Extensive parameterizations allow optimum adaptation to different encoder types.

Special features:

• automatic baud rate detection up to max. 1 MHz
• Coding: Gray and binary
• Data length up to 32 bit, flexibly adjustable.
• separate evaluation of a status error bit (power fail bit) in the process data.

Via the distributed clocks function, the time of data acquisition from the encoder can be output via timestamp. The encoder profile allows the process data to be linked quickly and easily to the motion control application.
