Matters needing attention

1.Oil and water protection of servo motor 1) The servo motor can be used in the place that will be attacked by water or oil drops, but it is not completely waterproof or oil-proof. Therefore, the servo motor should not be placed or used in the environment of water or oil invasion. 2) If the servo motor is connected to a reduction gear, the oil seal should be filled when using the servo motor to prevent the oil of the reduction gear from entering the servo motor 3) The cable of servo motor should not be immersed in oil or water.
