Drive connections
The maximum length of the cable between the Motion Controller and motor depends on
the sensor system used and the electrical and magnetic fields in the environment.
Tab. 8:
Guide values for the cable length
Longer connection cables are generally permissible, but must be validated for the target
installation.
Optimization of the behavior in respect of transient emission and interference resistance
may require additional EMC measures (see chap. 4.3, p. 43).

Connection of the power supply
Discrete inputs and outputs (for instance for discrete set-point specification or for con
-
nection of limit switches and reference switches)
Communication connections
Make sure that the connection cables on the connection side are not longer than 3 m.
Keep the shield connections for connection cables short and flat.
To reduce the effects on the DC power supply network, ferrite sleeves (such as WE 742 700
790) can be used on the supply cables.
