Control cables
General recommendation
Use shielded cables, temperature rated at 60ºC (140ºF) or
above.
The following figure shows examples of recommended cables.

•
Control cables must be multi-core cables with a braided
copper wire screen.
•
The screen must be twisted together into a bundle not longer
than five times its width and connected to terminal X1-1 (for
digital and analog I/O cables) or to either X1-128 or X1-32
(for RS485 cables).
Route control cables to minimize 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 90º as possible to minimize
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 > 48 V). Relay-controlled signals using less than 48 V
can be run in the same cables as digital input signals.
