Beckhoff micro-increments for ultra-fine position resolution

Beckhoff micro-increments for ultra-fine position resolution

This video explains the micro-increment principle that is implemented in some feedback terminals from the EL5xxx series. The incremental encoder signal is sampled several times in each EtherCAT cycle. As a result, a shaft position and thus possible rotary oscillations can be measured much better than with the usual single sampling.

EL5101 | EtherCAT Terminal, 1-channel encoder interface, incremental, 5 V DC (DIFF RS422, TTL), 1 MHz

EL5101

The EL5101 EtherCAT Terminal is an interface for the direct connection of incremental encoders with differential signals (RS422) or TTL single ended signals. Input frequencies up to 1 MHz can be evaluated. Two additional 24 V digital inputs are available for storing, blocking and setting the counter status. The error message output of an encoder can be connected and evaluated via the status input. The 5 V and 24 V supply of the encoder can be provided directly via the terminal connection points.

The EL5102 EtherCAT Terminal is an interface for the direct connection of two incremental encoders with differential signals (RS422) or single ended signals (TTL and Open Collector), parameterizable per channel. Input frequencies up to 5 MHz can be processed. Two additional 24 V digital inputs are available for storing, blocking and setting the counter status. It is also possible to set the counter to a predefined value or to lock the counter directly through the process data. The error message output of an encoder can be connected and evaluated via the status input. The 5 V, 12 V or 24 V supply of the encoder can be provided directly via the terminal connection points.
