6.3.3 SSI absolute value encoder with Stegmann-SSI protocol
All SSI encoders which use the Stegmann SSI protocol are supported.
• Supported bit rates for SSI communication: 100 ... 1000 kbits
• Supported data word widths: 1 ... 31 bits (effective)
• Supported output code of the SSI encoder: Gray or binary
• The SSI encoder can be used as position encoder or master encoder with a minimum cycle time
of 1 ms.
• The SSI encoder can be supplied via X8 up to a maximum voltage of 12 V and a maximum
current of 0.25 A.
• The received SSI data words are provided to the application via the LS_MultiEncoder system
block for further processing in the function block editor.

Note!
For some SSi encoder types it is common that despite a high data transfer rate an slow
position detection (e.g. every 5, 10 or 20 ms) takes place. In this case, the position control,
working in a 1-ms cycle, only functions with low gain and thus low dynamics since the
values of the SSI encoder are only updated every x ms.
When an external SSI laser position encoder is used at X8:
