5.6.2 SinCos encoder at X8
ƒ You can connect a SinCos encoder with serial communication (single turn or multi
turn) to X8.
ƒ Use Lenze system cables in order to provide for a trouble−free operation.
ƒ Self−prepared cables have to be provided as follows:
– Only use cables with cores that are twisted in pairs and shielded, featuring the
specified cable cross−sections.
– Apply the shield to both sides.
