Resolver at X7
You can connect a resolver to X7 in order to record the speed and position.
ƒ
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.
