2.4.5 Oil and Water Prevention Measures for the Servo Motor
Please follow the following precautions and do not allow water, oil, or other foreign objects
to enter the servo motor:
1. Do not submerge the cable in oil or water.
2. If oil or water is unavoidable, please use oil-resistant cables. Delta does not provide
oil-resistant cables.
3. If the servo motor must be mounted with the shaft end up, do not use it in a machine,
gearbox, or other environment where the servo motor may have contact with oil or
water.
4. Do not use the servo motor in an environment with cutting fluid. Depending on the
type of cutting fluid, the sealing material, the coated colloids, cables, or other
components may be affected or even deteriorate.
5. Do not let the servo motor be in continuous exposure to oil mist, water vapor, oil,
water, or grease.
If you cannot avoid using the servo motor under the above conditions, please take
prevention measures to avoid dirt and water for the machine.
2.4.6 Measures to Suppress Temperature Increase of the Servo Motor
1. When installing the servo motor, please pay attention to the cooling conditions (such
as size of the heat sink) provided in the specifications of each servo motor type.
2. The servo motor generates heat during operation, and the heat generated by the
servo motor is dissipated to the heat sink through the motor mounting surface.
Therefore, if the surface area of the heat sink is too small, the temperature of the
servo motor may increase abnormally.
3. If it is difficult to apply large heat sinks in the operating environment or if the ambient
air temperature exceeds the given specifications, please take the following measures:
(1) Reduce servo motor full load rating: for more details, please refer to the
specifications of each servo motor type. When selecting servo motors, consider
motors with the power capacity 1 to 2 levels higher.
