Description
Cable type
Twisted cable pairs with screen against electromagnetic interference pickup
Plug type
Plug with grid dimension 5.08 mm (see Appendix A.3).
Table 3.3 Specification of the I/O lines (analogue)
Wiring information for analogue cables
Use only screened cables with twisted cable pairs.
Connect the screening at both ends with low impedance to earth potential and ensure
potential equalisation.
On the sensor side: connect the screen to an earthed machine part.
On the controller side: connect the screen to the screen bus.
To ensure electromagnetic compatibility:
Make sure the screen makes the correct contact at both ends. To this end, connect the
screen contacted extensively all around, for example via a clamp.
Do not lay the analogue cables parallel to cables with strong interference (e.g. cables
from converters to motors).
