Beckhoff EL5032-0090 | EtherCAT Terminal, 2-channel encoder interface, EnDat® 2.2

The EL5032 is used for direct connection of two encoders with EnDat® 2.2

interface. The bidirectional interface enables automatic readout of position

values, diagnostic data as well as internal and external temperature values

and the electronic nameplate of the encoder.

In addition, the EL5032 provides an encoder supply of 5 V or optionally 9 V.

Extensive functions enable a cost-effective and shortened commissioning.

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.

The EL5021 EtherCAT Terminal is used for the direct connection of a

measuring probe or encoder with sinusoidal, differential voltage output

1 VPP. Input frequencies of max. 250 kHz can be evaluated.

The current counter reading can be zeroed (reset) or stored separately

via the C track of the encoder, which is also called reference mark.

The 5 V supply to the encoder is provided directly via the terminal

connection points. The EL5021 features amplitude and frequency error

detection of the input signals.

The ED5002 EtherCAT Terminal is an SSI controller for the direct connection

of two absolute transducers with Synchronous Serial Interface (SSI).

Single-turn and multi-turn encoders are supported. The encoder can be

supplied with 24 V DC directly via the connection points of the terminal.

The EL9505 can be used for an optional 5 V DC encoder supply.

Extensive parameterization options allow optimum adaptation to different

encoder types.

The EL5001-0011 SSI monitor EtherCAT Terminal is used for monitoring

the data exchange between SSI controller and SSI device.

The encoder is powered via the existing SSI interface. The interface circuit

makes the incoming data stream available to the controller as a data word

in the process image. Various operating modes can be permanently set via

the control register.

The EL5001-0011 EtherCAT Terminal can be interconnected in an SSI

controller/device communication. It is used for passive reading of the data

exchange between SSI controller and SSI device (encoder). This enables

the current position value to be made available to other control modules.

The EL5001-0011 offers an optional 24 V encoder operating voltage.

Extensive parameterizations allow optimum adaptation to different encoder

types.

The ED4072 analog output terminal is a universal 10 V/20 mA output

module in the 16-bit class for simple control tasks. Standard signals

in the -10/0...+10 V or -20/0/+4...+20 mA ranges can be generated

per channel. CoE can be used to set each channel to U or I mode in

TwinCAT or from the controller.

The voltage and current outputs are single-ended, meaning that they

each refer to the 0 V DC power contact. All outputs are digitized with

a 16-bit resolution and transmitted to the higher-level automation

system under electrical isolation. With a technical output range of

±107% of the nominal range, unconventional setpoints, such as for

error reporting purposes, can also be output.

The current outputs can have high load resistances and report

overload, wire break, or – in the case of voltage outputs – a short

circuit.
