4.2.5 Precautions for the use of drag chain cables
When the motor cable needs to be moved or the cable is installed in a drag chain, please use a
special exible and bend-resistant cable. Ordinary cables are easily damaged during repeated
bending, causing the servo motor to fail to work properly.
When using drag chain cables, make sure that:
• Correctly select the cable that meets the required bending times
• Bending radius of the cable R generally be more than 10 times the diameter of the cable
• Avoid pulling the cable. When wiring inside the drag chain, do not x or bundle it, so as to avoid
pulling the cable due to insu󰀩cient bending radius when bending.
• Please bundle the cables at the two ends of the towline and where the mechanical parts are

Banding radius
• The wiring in the drag chain should not be too dense, and ensure that the cables occupy less
than 60% of the internal space of the drag chain
• Mixed wiring of cables with large di󰀨erences in outer diameter should be avoided. If mixed
wiring is indeed required, please set up baffles
4.2.6 Recommended Wires
• It is recommended to use an insulated wire with a withstand voltage of 600V and a temperature
above 75
℃
for the main circuit
• Be sure to choose a wire that uses the corresponding current to prevent the wire from
overheating
