Length of hybrid cable without communication
Allowed cable length depending on load
The maximum allowed total length is limited depending on the
kind of load on the hybrid cable.
Observe the following limit values for total length and segment
length within a drive line.
The number of KSM/KMS devices in the drive line has an
influence on the allowed cable length (see also chapter "Hybrid
cable length vs. KCU performance" on page 231 ).
