Incremental encoder interface with oversampling
| Information | |
| About product | The EL5101-0011 EtherCAT Terminal is an interface for direct connection of incremental encoders with differential inputs (RS422). It resolves the position value via oversampling, a process that makes it possible to increase the resolution of the position value to n times the bus cycle time. A traditional incremental encoder interface detects a counter value with each bus cycle and forwards it to the higher-level controller during the next fieldbus cycle. The EL5101-0011 repeatedly detects – configurable and equidistant – the actual counter value between two fieldbus communication cycles with an adjustable multiple integer of the bus cycle time (oversampling factor: n) and transfers 32-bit packages of n position values to the controller during the next fieldbus communication cycle. The minimum sampling time is 10 µs (100 ksps). The EL5101-0011 is used predominantly in areas where high-resolution position detection is critical. The 5101-0011 supports distributed clocks, i.e. the input data can be acquired synchronously with other data sources that are connected to distributed slave clocks. The system accuracy is < 100 ns.The EL5101-0011 EtherCAT Terminal is an interface for direct connection of incremental encoders with differential inputs (RS422).
