Environment
To ensure that the robot system operates and maintains maximum performance and to ensure its safe use, the robot system should be installed in an environment that meets the following requirements.
| Item | Conditions |
|---|---|
| Ambient temperature * | Installation: 5 to 40°C Transport, storage: -20 to 60°C |
| Ambient relative humidity | Installation: 10 to 80% (no condensation) Transport, storage: 10 to 90% (no condensation) |
| Fast transient burst noise | 1 kV or less (signal line) |
| Electrostatic noise | 4 kV or less |
| Altitude | 1000 m or less |
* The ambient temperature requirement is for the Manipulator only. For details on the environment requirements for the connected Controller, refer to the Robot Controller manual.
KEY POINTS
When used in a low-temperature environment near the minimum temperature specified in the product specifications, or when the unit is idle for a long period of time during holidays or at night, a collision detection error or similar error may occur immediately after the start of operation due to high resistance in the drive unit. In such cases, warm-up operation for about 10 minutes is recommended.
KEY POINTS
If there are conductive objects such as fences or ladders within 2.5 m of the Manipulator, these objects must be grounded.
Also, depending on the environmental specifications of the Manipulator, the following requirements must be met.
| Environmental Specifications | Conditions |
|---|---|
| S, C, P | - Install indoors. - Keep away from direct sunlight. - Keep away from shocks or vibrations. - Keep away from sources of electric noise. - Keep away from explosive areas. - Keep away from large quantities of radiation. |
| S, C | - Keep away from dust, oily smoke, salinity, metal powder, and other contaminants. - Keep away from flammable or corrosive liquids and gases. - Keep away from organic solvents, acids, alkalis, and chlorine cutting fluids. - Keep away from water. |
The following items should also be taken into consideration for the installation environment of Manipulators with protected-models.
- These are compliant with the IP67 protection class (IEC 60529, JIS C0920). The Manipulators can be used in environments where the possibility of dust, water, and water-soluble cutting oil falling of the Manipulator exists.
- They can be installed in environments where dust, oil smoke, metal powder, and similar substances are airborne, but they are not suitable for use with nitrile rubber oil seals, O-rings, packings, liquid gaskets, or other substances that impair sealing performance.
- The Manipulator cannot be used in environments exposed to liquids or airborne droplets that are corrosive such as acids or alkalis.
- In environments that are exposed to airborne droplets containing salt, rust may also form on the Manipulator.
- Manipulator surfaces are generally oil-resistant, but if special oils are to be used, oil resistance should be checked before use. For more information, please contact the supplier.
- In environments with rapid changes in temperature and humidity, condensation may form inside the Manipulator.
- When handling food directly, it is necessary to make sure that the Manipulator is not likely to contaminate the food. For more information, please contact the supplier.
- The Controllers used with Manipulators with protected-models do not have protection against harsh environments. The Controller should be installed in a location that meets its operating environment requirements.
KEY POINTS
If the Manipulator will be used in a location that does not meet the above requirements, please contact the supplier.
WARNING
Always use a circuit breaker for the Controller's power supply. Failure to use a circuit breaker may result in an electrical shock hazard or malfunction due to an electrical leakage. Select the correct circuit breaker based on the Controller that you are using. For details, refer to the following manual.
"Robot Controller Manual"
CAUTION
- When cleaning the Manipulator, do not rub it strongly with alcohol or benzene. Coated surfaces may lose their luster.
