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