## Connected

- Manufacturer: [Nachi Robotics](https://machineschema.com/manufacturer/nachi-robotics.md)

## Safety

- Explosion-proof construction is not available.
- Operating ambient temperature is 0 to 45 °C; humidity is 20 to 85%RH with no dew condensation allowed.
- Vibration at the installation face must not exceed 0.5 G (4.9 m/s²).
- Permitted operating height is not higher than 1,000 m above sea level; use in higher locations affects the permitted temperature.
- Measured noise is 79.6 dB(A) with maximum payload and maximum speed.

## Study notes

- The basic specifications table gives the robot model as SRA100HB-01.
- The SRA-H series uses an FD controller for spot welding; FD is not in the provided controller id list.
- The hollow arm routes pneumatic, power, and servomotor cables internally and eliminates external dress packages.
- Forearm allowable load is 20 kg.
- Allowable static load torque is 650 N·m on Axis 4 and 315 N·m on Axis 5.
- Allowable moment of inertia is 85 kg·m² on Axis 4 and 45 kg·m² on Axis 5.
- Applications listed are machine tending, material handling, palletizing, spot welding, and dispensing.
- Mounting is floor mount.
- Repeatability conforms to JIS B 8432, and noise is measured under JIS Z 8737-1 (ISO 11201).
