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.
- 620 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.
- 2,900 mm 84th pct in class
- Repeatability
How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.
- 0.06 mm 16th pct in class
- Path repeatability
How consistently the robot retraces a continuous path (for welding, dispensing). Lower is better.
- 0.07 mm 80th 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.
- 6
- Wrist torque
Allowable torque at the wrist axis — how much twisting force a tool can apply. Higher handles bigger/offset tools.
- 4,635 N·m 95th pct in class
Motion range & speed
Per-axis travel limits and rotational speeds.
Motion range and maximum speed per joint.
| Axis | Range | Max speed |
|---|---|---|
| J1 | -170° to 170° | 75 °/s |
| J2 | -65° to 82.2° | 60 °/s |
| J3 | -27° to 130° | 55 °/s |
| J4 | -300° to 300° | 100 °/s |
| J5 | -130° to 130° | 100 °/s |
| J6 | -360° to 360° | 150 °/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.
- 2,590 kg
- Base footprint
Length × width of the mounting base — the floor space the robot occupies.
- 1020 × 795 mm
- Mounting
Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).
- floor
Power & controller
Electrical supply and the control cabinet that drives it.
- Power supply
Required input voltage / phase for the controller.
- 3x380-480 VAC, 50/60 Hz
- Controller
The control cabinet / unit that runs the robot.
- OmniCore V250XT/V400XT
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.
- IP67 71th pct in class
- Operating temp
Ambient temperature range for normal operation.
- 5 to 50 °C
- Humidity
Permissible relative-humidity range (non-condensing).
- ≤ 95 %RH
- Noise level
Operating sound pressure level. Lower is quieter.
- 70 dB(A) 78th pct in class
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
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
- Languages
Native robot programming language(s) — e.g. KRL (KUKA), RAPID (ABB), URScript (UR), INFORM (Yaskawa).
- RAPID
- Teach pendant
The handheld programming/jog device supplied.
- FlexPendant
- Offline programming
Whether programs can be built and validated offline in a digital twin before deployment.
- Yes
