Hardware · `MZS05-01` · verification: source checked

The Nachi Robotics MZS05-01 is a six-axis collaborative articulated robot with a 5 kg wrist payload and 927 mm maximum reach. It uses AC servo drives and includes collision detection for operation in shared workspaces. It is intended for tasks such as machine tending, small-part assembly, and material handling.

## Safety

- Complies with ISO 10218-1, ISO 13849-1, and ISO/TS 15066 collaborative robot safety standards.
- Built-in collision detection sensors respond to external forces to protect nearby workers.
- Continuous robot status monitoring is performed through the control panel safety unit.
- A robot monitoring unit RMU50-11 (ISO 13849-1) restricts J2 and J5 operable range when shipped to reduce clamping risk; range changes require risk assessment in the actual environment.
- There is a clamping risk if J2 and J5 are operated at their maximum limits, even without tools or work; loaded tools or work can create clamping risk even with restricted range.
- An explosion-proof version is not available.
- The robot cannot be installed on surfaces inclined 30° or more; install on an incline less than 30°.
- Do not use liquid substances that degrade sticker parts, including organic solvents, acids, alkaline substances, chlorinated substances, and gasoline-based cutting fluids.
- Splashing liquids or mist can trigger proximity sensors and cause the robot to stop.
- When used for collaborative operation, floor or hand vibrations may stop the robot; eliminate vibration sources before use.
- A risk assessment according to ISO 12100 is required, and the speed at which the colliding part operates must be determined.

## Study notes

- Structure: articulated robot with AC servo drive.
- TCP speed is 2500 mm/s during non-collaborative operation and 1000 mm/s during collaborative operation.
- Hollow wrist routes cables internally to reduce external clutter and interference.
- Clean rating is ISO Class 4 equivalent; noise level is 75 dB.
- Air tubes: φ6×2, with operable pressure range 0.1 to 0.5 MPa.
- Application signal cables: 20 or 12 wires depending on option; LAN: none, 8-wire single system, or 8-wire dual system depending on option.
- Ambient humidity: 20% to 85% RH with no dew or frost; vibrations: ≤0.5 G (4.9 m/s²).
- Maximum static load torque: J4 16.9 N·m, J5 16.9 N·m, J6 9.4 N·m.
- Maximum moment of inertia: J4 0.49 kg·m², J5 0.49 kg·m², J6 0.15 kg·m².
- Additional information lists weight 588 kg, which conflicts with the general specification robot mass of 60 kg.
- Additional information lists mount options Angle, Cleanroom, Floor, Tabletop, Tilted, Wallmount, Invert/Ceiling Mount, and Shelfmount, while the general specification states floor installation and no incline of 30° or more.
