Applications
- Counting: Counts pulse and incremental encoder signals, including continuous counting, hardware or software gating, event-controlled stop, and synchronization via digital input.
- Position detection: Performs incremental and absolute position acquisition.
Key Features
- Encoder and position functions: Supports RS-422 incremental encoders and SSI absolute encoders for counting and position detection.
- Digital I/O: Provides 2 parameterizable digital inputs and 2 parameterizable transistor outputs.
- Encoder signal performance: Supports input frequencies up to 1 MHz and counting frequencies up to 4 MHz with quadruple evaluation.
- SSI absolute encoder: Supports parameterizable telegram lengths from 10 … 40 bit and clock frequencies up to 2 MHz.
