## Safety

- Ambient operating temperature is 0 to 45°C, ambient humidity is 20 to 85%RH with no dew or frost, and vibration must not exceed 0.5G (4.9 m/s²).
- Use at 1000 m or lower sea level; ambient temperature has limitations when the allowable altitude is exceeded.
- Motion range is limited for wall and tilted mounting; for wall mount, axis 1 motion range is ±30°.
- Do not use fluids that cause deterioration of sealants, including gasoline-based cutting fluids, chlorine, alkali, acids, and organic solvents.
- An explosion-proof version is not available.
- The wire-harness portion is IP65 equivalent and the robot controller is IP20 equivalent.
- For cleanroom use, install the robot in a down-flow type cleanroom. The robot packaging is not dust proof; clean the robot by wiping it or removing dust and fine particles before bringing it into the cleanroom.

## Study notes

- The MZ50LF corresponds to model column M250LF-01 in the general specifications table.
- Structure is an articulated robot driven by AC servo motors.
- Position repeatability is listed as ±0.06 mm and conforms to JIS B 8432.
- Air tubes are φ10x2 and application cables are 24 wires.
- Maximum static load torque is 216 N·m for J4 and J5 and 147 N·m for J6.
- Maximum velocity depends on the operation program and wrist load condition.
- Clean rating is equivalent to ISO Class 4 based on an internal assessment in accordance with ISO 14644-1.
- Noise level is 80 dB, A-weighted equivalent sound level measured under JIS Z 8737-1 (ISO 11201) with maximum payload and maximum velocity.
- Applications listed are machine tending, material handling, palletizing, and dispensing.
