Beckhoff EL5002 | EtherCAT Terminal, 2-channel encoder interface, SSI

The EL5002 EtherCAT Terminal is an SSI controller and enables the direct

connection of two absolute encoders with SSI (synchronous serial interface).

Both singleturn and multiturn encoders are supported. An EL91xx power

supply terminal can be used for a 24 V supply to the encoder, and the

EL9505 for the optional 5 V encoder operating voltage.

Extensive parameterizations allow optimum adaptation to different encoder

types.

Special features:

• parameterization per channel possible

• baud rate 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

In addition, the EL5002 offers a multiple transmission mode for clock

pulses to check data integrity. Via the distributed clocks function, the

position value is read out exactly synchronously with other processes.

If the distributed clocks function is deactivated, the EL5002 clocks

synchronize with the EtherCAT cycle. The encoder profile enables simple

and fast linking of the process data for motion control applications.
