EPP5101-0011 - Introduction
Incremental encoder interface with differential inputs
The EPP5101-0011 EtherCAT Box is an interface for direct connection of incremental encoders with differential signals (RS422) or TTL single-ended signals. Input frequencies up to 1 kHz can be evaluated. Two additional 24 V digital inputs are available for saving, locking and setting the counter value. The fault signal output of an encoder can be connected and evaluated via the status input. The encoder is supplied with 5 V directly via the D-sub socket of EPP5101-0011.
Special features:
- Options for saving, locking and setting the counter
- Integrated frequency and period measurement
- Can optionally be used as 5 V counter
- Microincrements functionality
- Synchronous reading of the position value via Distributed Clocks
- Timestamp on the last registered incremental edge
In addition, the EPP5101-0011 allows measurement of a period or frequency with a resolution of 100 ns. Due to the optional interpolating micro-incremental functionality, the EPP5101-0011 can supply even more precise axis positions for dynamic axes. The high-precision EtherCAT distributed clocks (DC) support synchronous reading of the encoder value together with other input data in the EtherCAT system. In addition, a timestamp is available for the last registered incremental edge. The use of encoder profiles allows the simple and fast linking of the process data to the Motion Control application.
