## Safety

- Operating range is limited according to payload weight.
- The allowable moment of inertia of the wrist changes with load conditions.
- Maximum air pressure must not exceed 0.49 MPa (50 kgf/cm²).
- Operating temperature is 0 to 45 °C.
- Humidity must be 20 to 55%RH with no condensation.
- Vibration to the insulation flow must not exceed 0.5 G (3 m/s²).
- Do not use organic compounds, acids, alkalis, chlorine, or gasoline cutting fluids that deteriorate seal material.
- Installation altitude is limited to 1,000 m above sea level; higher altitude affects permitted temperature.

## Study notes

- Robot model is listed as MC20-01 in the basic specifications table; the page title is MC20.
- Drive system is an AC servo motor.
- Maximum speeds for MC20-01 are listed as 2.96 rad/s on axes 1 and 2, 2.86 rad/s on axis 3, 6.28 rad/s on axes 4 and 5, and 10.5 rad/s on axis 6.
- Allowable static load torque is 49 N·m on axes 4 and 5 and 23.5 N·m on axis 6.
- Allowable moment of inertia is 1.6 kg·m² on axes 4 and 5 and 0.8 kg·m² on axis 6.
- Maximum air pressure is 0.49 MPa (50 kgf/cm²).
- Humidity range is 20 to 55%RH with no condensation allowed.
- Vibration limit is 0.5 G (3 m/s²).
- Installation altitude is not higher than 1,000 m above sea level; above this, permitted temperature is affected by height.
- The basic specification table lists floor and ceiling mounting for MC20-01; additional information lists floor, wall, and inverted/ceiling mounting.
- Application areas listed are machine tending, material handling, palletizing, and dispensing.
