Control Cable Selection
It is strongly recommended that double shielded twisted pair cables (one individual shielded pair per signal) be
used for both analogue and digital control signals (but single shielded twisted multi pair cable may be used for
low voltage digital signals if desired). Analogue and digital signals must be run in separate cables. A common
return path should not be used for different analogue signals. For encoder cabling, the directions given by the
encoder manufacturer should be followed. Low and high voltage signals should never be run in the same cable.

Cable Routing
There are three main categories of cabling for the drive discussed in previous sections (above);
Motor cables: connecting motor and drive, these supply power to/from the
motors.
Control cables: returning information from the motors to the drives (e.g.
Encoder info or temp info) or running information between drives or to other
control units on the machine (e.g. Relays to/from master controllers).
Input power cables: connecting power supply unit and drive, this supplies
power to/from the drives.
