6.3.8.1 "LS_SsiEncoderX8" system block
The LS_SsiEncoderX8 system block provides the SSI data words received to the application for
further processing in the function block editor.
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

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.
