"LS_SsiEncoderX8" system block

Outputs

Gray-binary conversion
If an SSI encoder with Gray coding is used, a data conversion of Gray-to-binary code can be

connected in

C00437/1...8

individually for each output of the LS_SsiEncoderX8 SB, and thus for each

partword.

• In the Lenze setting "Binary coded" there is no conversion, i. e. an SSI encoder with binary coding

is expected.

Note!

• The LS_SsiEncoderX8 SB is only provided within controllers with a MM3xx or MM4xx

memory module.

• If a position is transmitted in the SSI data word, it is output in an unchanged manner

with regard to the position format by the LS_SsiEncoderX8 SB. For a use of the SSI

encoder as position encoder the position has to be converted into the 9400 format

afterwards by means of the L_EsEncoderConv FB.

Identifier

Data type

Value/meaning

SSI_dwDataword_1

DWORD

SSI partword 1

• In the Lenze setting the complete SSI data word received is shown at this output

without a conversion of the data format.

SSI_dwDataword_2

...

SSI_dwDataword_8

DWORD

SSI partwords 2 ... 8

• In the Lenze setting these outputs are deactivated.
