Interface terminals for SSI encoders
The EL5001 SSI interface EtherCAT terminal is for the direct connection of an SSI encoder, the EL5002 2-
channel SSI interface EtherCAT terminal for the direct connection of two SSI encoders. The interface circuit
generates a pulse for reading the encoder, and makes the incoming data stream available to the controller
as a data word in the process image. Various operating modes, transmission frequencies and bit widths can
be permanently stored in a control register.
The EL5002 and EL5001 from FW10 feature distributed clock functionality. Cyclic reading of the SSI encoder
can thus be started with high precision, enabling detailed dynamic analysis of the axis in the control system.
The EL5002 and EL5001 from FW10 have a new, alternative process image for simpler commissioning from
TwinCAT 2.11. The tried and tested process image consisting of value and status continues to be set in
delivery state.
