The maximum cable length at the encoder system interface depends on the current
consumption of the encoder system and the cross-section of the supply cores in the cable.
However, the maximum length is 10 m.
For encoder systems that operate in a supply voltage range from 4.75 V to 5.25 V, the
following diagram is obtained. The sample parameters shown are 0.28 mm² cross-section
(0.14 mm² supply cores plus 0.14 mm² Remote Sense cores) and 0.64 mm² (0.5 mm² supply
cores plus 0.14 mm² Remote Sense cores).
