EL5001 | EtherCAT Terminal, 1-channel encoder interface, SSI

The EL5001 EtherCAT Terminal is an SSI master and enables the direct connection of an absolute encoder with SSI (synchronous serial interface). Both single turn and multi turn encoders are supported. The 24 V supply of the encoder can be provided directly via the terminal connection points. The EL9505 power supply unit terminal can be used for an optional 5 V encoder operating voltage.

Extensive parameterization allows optimum adaptation to different encoder types.

Special features:

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

Via the distributed clocks function, the position value is read out exactly synchronously with other processes. If the distributed clocks function is deactivated, the EL5001 clocks synchronize with the EtherCAT cycle. The encoder profile enables simple and fast linking of the process data for motion control applications.
