Axioline special function module, 2 counter inputs, 2 incremental encoder inputs (including bus base module and
connectors)
Product description
The module is designed for use within an Axioline station.
On the one hand, it is used to acquire fast pulse sequences from sensors, and on the other hand to detect positions using incremental encoders.
The module combines two counter inputs for the evaluation of fast counter pulses and two incremental encoder inputs for position detection.
Product Features
2 counter inputs
2 incremental encoder inputs
Maximum input frequency: 300 kHz/100 kHz (depending on the wiring)
32-bit counter (up and down)
Output control according to two limit values
Counter: counting (source) is controlled via a control input (gate)
Counter: single or periodic counting
Incremental encoder acquisition: acquisition of digital signals from symmetrical and asymmetrical incremental encoders
Incremental encoder acquisition: evaluation of linear or rotary axes
Device rating plate stored
