EL5031-0011 | EtherCAT Terminal, 1-channel encoder interface, EnDat® 2.2, oversampling

The EL5031-0011 is used for the direct connection of an encoder with an EnDat® 2.2 interface. The bidirectional interface enables automatic reading of position values, diagnostic data, internal and external temperature values, and the electronic nameplate of the encoder. The EL5031-0011 is characterized by the fact that the position values for finer resolution are processed according to the oversampling principle. An encoder supply of 5 V – or optionally 9 V – is also provided. Extensive functions enable both cost-effective and faster commissioning.

Special features:

• high-resolution position detection using the oversampling principle
• conversion time: up to 40 ksps, new position value every 25 µs
• automatic reading of the electronic nameplate
• storage of user-defined data in the encoder
• position value output with up to 48 bits (depending on the encoder resolution)
• integrated encoder supply

A conventional EnDat® 2.2 interface registers a position value with each PLC cycle and passes it on to the higher-level controller in the next fieldbus cycle. The EL5031-0011 reads the current position value at several configurable and equidistant times between two fieldbus communication cycles with an adjustable whole number multiple (oversampling factor: n) of the cycle time. The transfer of a packet of n position values of 48 or 32 bits each to the higher-level controller takes place in the next fieldbus communication cycle. The minimum sampling time here is 25 µs (40 ksps). Notable application areas of the EL5031-0011 can be found in the field of high-resolution position measurement with in-line or end-of-line measurement systems, especially in automated manufacturing processes.
