3.4.2.2 Cable lengths
SSI clock frequency and cable quality determine the maximum cable length.
TR’s own hybrid cable (part number: 64-200-021) was used for the measurements.

Other cable parameters, frequencies, and ambient temperatures as well as bearing heat and
temperature increase via the shaft and flange, can yield a considerably poorer result in practice.
Therefore, the fault-free function of the SSI interface with the application-dependent parameters must
be checked prior to productive operation.
