EL5101-0010 | EtherCAT Terminal, 1-channel encoder interface, incremental, 5 V DC (DIFF RS422), 5 MHz
EtherCAT timestamp: high-precision interaction of controller and environment – to the exact nanosecond
Beckhoff micro-increments for ultra-fine position resolution
Distributed Clocks: the integrated time management system in EtherCAT
The EL5101-0010 EtherCAT Terminal is an interface for the direct connection of incremental encoders with differential signals (RS422). With a maximum input frequency of up to 5 MHz it is particularly suitable for dynamic applications. 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.
Special features:
- save, lock, set counter
- integrated frequency and period measurement
- open-circuit recognition
- synchronous reading of the position value via distributed clocks
- timestamp on the last-registered incremental edge
In addition, the EL5101-0010 enables the measurement of a period or frequency with a resolution of 100 ns. It also supports synchronous reading of the encoder value together with other input data in the EtherCAT system via the high-precision EtherCAT distributed clocks (DC). A timestamp for the last-registered incremental edge is also available. The use of encoder profiles enables simple and fast linking of the process data for motion control applications.
