EL5131 | EtherCAT Terminal, 1-channel encoder interface, incremental, 5 V DC, 5 MHz, with 2 x digital output 24 V DC
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 EL5131 EtherCAT Terminal is an interface for the direct connection of incremental encoders with differential signals (RS422) or single-ended signals (TTL and open collector). Two parameterizable 24 V DC push-pull, tristate outputs are available, which are set after reaching a specified count, frequency or speed value. This allows the realization of a digital cam controller, which uses position or time cams and ensures a precise response time independent of the fieldbus cycle.
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.
Special features:
- save, lock, set counter
- parameterizable 2 x 24 V push-pull, tristate outputs
- digital cam controller with position cams or time cams
- integrated frequency measurement
- optionally usable as 5 V up/down counter
- microincrements
- synchronous reading of the position value via distributed clocks
- timestamp on the last registered incremental edge, latch values and the output switching limits
In addition, the EL5131 enables the measurement of a frequency or velocity with a resolution of 10 ns. A duty cycle measurement of the input signal is implemented.
With the optional interpolating microincrement functionality, the EL5131 can provide even more accurate axis positions for dynamic axes. 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). Additionally, timestamps are available for the last registered incremental edge, the edge at the latch input, the zero pulse track C and the output switching limits. The use of encoder profiles enables simple and fast linking of the process data for motion control applications.
