Full specifications
Performance
How much it lifts, how far it reaches, how precisely it repeats.
- Payload
Maximum mass the robot can carry at the wrist flange, including the gripper/tool. Higher means it can handle heavier parts.
- 50 kg 97th pct in class
- Reach
Maximum horizontal distance from the base axis to the wrist — defines the size of the work area. Higher means a larger envelope.
- 1,200 mm 93th pct in class
- Repeatability
How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.
- 0.025 mm 7th pct in class
- Axes (DOF)
Number of independently driven joints / degrees of freedom. 6 is standard for articulated arms; 4 for SCARA/palletizers; 7 adds elbow redundancy.
- 4
- Max TCP speed
Top linear speed of the tool centre point. Higher means faster cycle times.
- 9,608 mm/s 81th pct in class
- Wrist inertia
Allowable moment of inertia at the wrist — how much rotating mass it can swing without overload. Higher is more capable.
- 2.45 kg·m² 95th pct in class
Motion range & speed
Per-axis travel limits and rotational speeds.
- Max axis speed
Highest rotational speed of the fastest joint. Higher helps short, fast moves.
- 658 °/s 4th pct in class
Motion range and maximum speed per joint.
| Axis | Range | Max speed |
|---|---|---|
| J1 | -165° to 165° | — |
| J2 | -150° to 150° | — |
| J4 | -360° to 360° | 658 °/s |
Physical
Size, mass and how it mounts.
- Robot weight
Mass of the manipulator (arm) without controller. Lighter eases mounting and mobile use; heavier often means stiffer/higher payload.
- 145 kg
- Mounting
Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).
- floor
Environment
Conditions it can operate in — dust, water, temperature, cleanliness.
- IP rating (arm)
Ingress protection of the body against dust/water (IEC 60529). First digit = dust, second = water. Higher resists harsher environments.
- IP54 88th pct in class
- Humidity
Permissible relative-humidity range (non-condensing).
- 10 to 80 %RH
Safety
Standards met and collaborative-operation capability.
- Collaborative
Whether the robot is designed to work safely next to people without fencing (power-and-force-limited).
- No
- Safety standards
Certified safety standards (ISO 10218-1, ISO/TS 15066) and functional-safety level (PLd/PLe, SIL2/3).
- ISO 10218-1
Control & software
Programming, languages and ecosystem.
- Programming
How the robot is taught: pendant, hand-guiding (lead-through), block/flow-chart, scripting, offline simulation.
- teach-pendant, offline-sim
- ROS support
Robot Operating System driver availability (none / ROS 1 / ROS 2 / both).
- none
