Functional Features​
High-speed quadrature counting
Position latching and reference homing
Encoder power integrated
Analog feedback output
PLC backplane communication
Application Scenarios​
Motion control
Axis position feedback
Speed measurement
Synchronous machine control
Working Principle​
Incremental encoder A/B pulses are counted with selectable quadrature decoding, reference pulse performs homing, position/speed result is passed to PLC, and ±10 V output provides external analog feedback.
Installation Requirements​
Insert into compatible B&R controller or I/O rack
Use shielded encoder cable
Separate encoder ground from power ground as required
Usage Notes​
Keep encoder cables away from power cables.
Set counting direction and resolution in Automation Studio.
Wrong reference-pulse wiring causes homing error.
