2.6 Note about cable shielding
The conductor of the analogic signal must be twisted
and shielded, and the shield must be connected to
ground as illustrated below:
control signal cables
motor cables
The shield of the motor cable (power and signal cables) are connected as follows:
•
drive side
(20:50cm)
remove the outside sheath and fix shield to the zinced pannel, by using a
u-clamp (Axor's cables have incorporated u-clamp):
note
:
• To reduce the capacitive and inductive coupling, these cables must be run keeping a distance of more
than 30cm from the power cables (10 cm if they are shielded).
• If it is absolutely necessary to cross the control cables with the I/O's, do so at 90°, in order to reduce
the effect of the magnetic fields.
•
motor side
the shield is internally connected to the metal ring of the motor connector, thus to
earth through the motor's carcass.
Remove the outside sheath and
affix the shield to the dedicated
retainer rings, by using plastic
clamps.
Chassis: Connect the
screw to the ground
bar.
