1)
The maximum cable length for the encoder system interface depends
on the current consumption of the encoder system and the cross-section
of the wires in the cable. However, the maximum length is 10 m (32.8 ft)
(for further details see Manual SINAMICS S120 Control Units and
Supplementary System Components).
