Control cables
General recommendation
Use shielded cables, temperature rated at 60 °C (140 °F) or
above.
The figure below shows examples of recommended cables.

•
Control cables must be shielded and of twisted pair type.
•
The shield must be twisted together into a bundle (pigtail) not
longer than five times its width and connected to terminal
X1:1 (for digital and analogue I/O cables). For connecting the
shield wires of the RS485 cable, see the instructions (and
note 3) on page 142.
Route control cables to minimise radiation to the cable:
•
Route as far away as possible from the input power and
motor cables (at least 20 cm [8 in]).
•
Where control cables must cross power cables make sure
they are at an angle as near to 90° as possible to minimise
interference.
•
Keep at least 20 cm (8 in) away from the sides of the drive.
•
Run relay-controlled signals as twisted pairs (especially if
voltage > 30 V). Relay-controlled signals using less than
30 V can be run in the same cables as digital input signals.
