Cable Assemblies
Characteristics - Power and Signal Cables
Cables are an important part of a servo system
installation. Not only must the noise immunity and
integrity of the cabling and connectors be correct, but
SAFETY and EMC regulations must be complied with
to ensure successful, reliable and fail-safe operation.
One of the most frequent problems experienced by
motion systems engineers is incorrect wiring
connections of the motor to the drive.
Control Techniques’ ready-made cables mean
system installers can avoid the intricate, time
consuming assembly normally associated with
connecting servo systems. Installation and set-up
time are greatly reduced - there is no fiddling with wire
connections and crimp tools, and no fault finding. The
cables are made to order in lengths from 3m to 100m
and are available for all standard Unimotor options.
Features

conductors in
signal cable for low volt drop
• Braided screen for greater flexibility and wear
• Power cables with or without brake
• Shielded brake supply wires
• Cable assembly type identification label
Applications
• For general applications choose PVC type. This has
good all round performance.
• Use PUR for high dynamic applications where cable
is frequently in motion.
• Use PUR for machine tools where the cable is
sprayed with coolant fluid.
• 2.5 mm
