The ER5151-0002 EtherCAT Box is an interface to 24 V DC single-ended signals. Two additional 24 V digital inputs are available for saving, locking and setting the counter value. The alarm output of an encoder can be connected and evaluated via the status input. The encoder is supplied with 24 V directly via the D-sub socket of ER5151-0002.
Special properties:
- save, lock, and set counters
- integrated frequency and period measurement
- can optionally be used as a counter
- microincrements functionality
- synchronous reading of the position value via distributed clocks
- timestamp on the last registered incremental edge
In addition, the ER5151-0002 enables the measurement of a period or frequency at a resolution of 100 ns. Thanks to the optional interpolating microincrements functionality, the ER5151-0002 can provide even more accurate axis positions for dynamic axes. It supports synchronous reading of the encoder value together with other input data in the EtherCAT system via the high-precision EtherCAT Distributed Clocks (DC). In addition, timestamps are available for the last registered incremental edge. The use of encoder profiles allows the process data to be linked to the motion control application quickly and easily.
