6.3.10 Provision of the encoder signal of input X8

This function extension is available from software version V7.0!

The LS_EncoderX8 system block serves to provide the encoder signal of input X8 to the application,

independent of the selected feedback system for the motor encoder and position encoder.

Application cases:

• High-resolution speed encoder as master encoder /value, correcting signal, ...

• Absolute value encoder for length measurements

• Display of the absolute encoder value without considering an offset

6.3.10.1 System block "LS_EncoderX8"

The LS_EncoderX8 system block provides the input X8 to the application in the function block editor.

Outputs

 Note!

For SSL encoders, the LS_SsiEncoderX8 system block must be used. Use of an SSI

encoder at X8 ( 252)

Value/meaning

ENC_dnEncoderOut1

C02762 |DINT

Display of the current encoder position (steps) within one revolution

•1 revolution ≡ 2

32

bits

Note:

In order to convert the encoder information/position into a position_p in the

internal measuring system, connect both outputs ENC_dnEncoderOut1 and

ENC_dnEncoderOut2 with the inputs dnEncoderIn and dnEncoderIn2 of the

FB L_EsEncoderConv. A storage with mains failure protection of the position signal

is also processed via this FB.

ENC_dnEncoderOut2

C02763 |DINT

Display of all revolutions of the encoder (only with Multiturn)

• After the max. presentable revolutions have been reached, the value jumps back

to "0".

• C02761

shows the max. presentable revolutions of the MultiTurn encoder

(encoder-dependent).

• In case of SingleTurn, the value "0" is always output.

ENC_dnActualSpeed_s

C02764 | DINT

Current encoder speed in [rpm]

ENC_bError

C02765 | BOOL

Status signal "Encoder error"

TRUE An encoder error has occurred.
