Page 17: Minimum Bending Radius
7. Cables and Wiring Cables and Wiring Minimum bending radius Handling of Encoder Cable The encoder cable is a bending resistant type with the minimum bending radius R36. Pay attention to the following points when installing. Note) If the installation is inappropriate, it may cause earlier line breakage. ●Cable Twist Cables should be wired straightly without any twist. - Page 18 7. Cables and Wiring Cables and Wiring ●Cable length Too long cable length could cause looseness while too short may cause tension at the fixing point. This may cause earlier line breakage. Adjust a cable to an optimum length when used. Fig.
