(6) Cable stress
Do not apply bending or tensile stress to the cable.
n Precautions for applications with moving servomotor
- Design a system of an application with a moving servomotor so that the cables are free from
forcible stress.
- Route the encoder cable and power cable in Cableveyor.
- Fix the encoder cable and power cable from the servomotor using cable clamps.
- Design the bending radius as large as possible.
- Do not allow bending stress or the weight of the cable itself to be exerted at cable connections.
(7) Protection against water and oil
Measures taken to the motor are useful for protection against moderate amount of splashes.
However, the shaft is not water-proof or oil resistant, and so take appropriate measures on the
machine side to avoid entry of water and oil into the servomotor.
In environment with much water or oil drops or oil mist, install a cover or the like on the machine
and connect lead wires and connector downward.
(8) Dimensional tolerances
The servomotor is assembled to the following accuracy.
