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

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 page144.
Route control cables to minimise radiation to the cable:
Route as far away as possible from the input power and
motor cables (see the figure on page 40).
Where control cables must cross power cables make sure
they are at an angle as near to 90° as possible.
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.
For relay signals 110/220 V use suitable cable type and keep
it away from other analogue or digital control cables.
