Applications
- Incremental encoder counting: Counts signals from pulse and incremental encoders, including A/B tracks with 90° phase offset.
- Absolute position feedback: Acquires position data from SSI absolute encoders using binary or Gray code.
- Digital signal control: Uses parameterizable digital inputs and outputs for gate, capture, synchronization, comparison-value switching, and freely usable signals.
Key Features
- Encoder channels: 2 channels for RS-422 incremental encoders or SSI absolute encoders.
- Digital I/O: 2 digital inputs and 2 digital outputs per channel; inputs and outputs are parameterizable.
