3.7 Precautions of Using Cables
1.  Do not bend or apply tensions to cables. The core wire of a signal cable is only 0.2 or 0.3 
mm thin. Handle the cables carefully. 
2.  In scenarios where cables need to be moved, use exible cables. Common cables are 
easily damaged after being bent for a long time. Cables of low power servo motors cannot 
be moved. 
3.  If cable towline is used, make sure: 
 
•
The bending radius of the cable must be at least 10 times of the diameter of the cable. 
 
•
Do not x or bundle the cables inside the cable towline. You can bundle them at both ends 
of the cable towline. 
 
•
Cables must not be wound or warped. 
 
•
Space factor inside the cable towline must not exceed 60%. 
 
•
Do not mix cables of great difference in size together. Otherwise, thick cables may crush 
thin cables. If you need to use them together, place a spacer plate to separate them.
