The maximum shaft speed under rated load can reach up to 800 °/s; accompanied by side view and top view drawings of the workspace.

load capacity

Rated load of 2 kg, maximum total load of 3 kg; rated moment of inertia of 0.045 kg · m ²; Rated center of gravity Lxy=60   mm, Lz=80   mm;

The load mass and moment of inertia must be verified simultaneously using the KUKA. Load tool, and the load parameters must be entered into the controller; Exceeding the limit will cause overload of the gear motor and shorten its lifespan. Provide a complete load curve chart.

The flange provides axial force, radial force, overturning moment, and torque under operating conditions and emergency stop conditions.

The forearm can be equipped with a small amount of additional load, with designated M3 threaded holes. All additional components are included in the total load and cannot exceed the upper limit of 3 kg.

Foundation load

Provide normal and maximum vertical force Fv, horizontal force Fh, overturning moment Mk, and A1 axis torque Mr under ground, ceiling, and wall installation conditions respectively;

Structural design must use the maximum load value, and failure to design the foundation according to the maximum value can result in personal injury and equipment damage. Additional loads need to be added to the calculation of foundation stress.

sign

Multiple multilingual safety nameplates on the body: axle fixation warning, transportation location identification, hazardous area warning, and complete machine model nameplate; The nameplate is prohibited from being torn off or altered, and must be replaced if it is blurry.

REACH Regulation Information

The proportion of SVHC substances of high concern in product quality is less than 0.1%.

Stop travel and stop time (safety critical)

Definition: Stop stroke=Reaction stroke+Braking stroke, the stop time is from the stop signal to complete stillness; Mainly investigate A1/A2/A3; The stopping stroke of multi axis compound motion will increase.

Shutdown category:

STOP   0 (Category 0): Directly cut off the drive and lock the brake;

STOP   1 (Category 1): Controlled braking along the trajectory, cutting off the driving brake after 1 second;

STOP   2 (Category 2): Drive not turned off, slope deceleration.

Test conditions differentiate arm extension ratio (33%/66%/100%), program magnification POV, load mass m; the document comes with a large number of stop stroke and stop time charts;

STOP0 data is the average reference value for simulation and testing; The brake will wear out with the number of STOP0 triggers; Require at least on-site testing of actual travel stops every year.

Safety

Responsibility and Legal Framework

Robots belong to semi-finished products, and system integrators are responsible for the risk assessment of the entire equipment, issuing EC conformity statements, and affixing CE markings; KUKA provides an Assembly Declaration.

Modification of robots is prohibited without permission from KUKA; The damage caused by third-party tooling accessories shall be the responsibility of the user/integrator.

Definition of terms: Hazardous area (work area+stop travel), protective area, T1 manual low-speed mode, T2 manual high-speed mode, various types of shutdown, system integrator, operator.

Personnel Classification

Divided into operators, system integrators, debugging/maintenance/operation/cleaning personnel; Responsibilities of different roles; All personnel must read the safety chapter in its entirety and complete the training before starting work.

Work area, protective area, hazardous area

The hazardous area includes the working range and stopping travel, requiring physical protection; The protective zone is outside the danger zone.

Overview of protective equipment

Mechanical hard limit; Optional mechanical shaft limit;

Non actuated mobile robotic arm means: free rotation device, brake release device (only used for emergency rescue, frequent use may damage the brake);

The safety label of the main body shall not be removed.

safety measures

General safety: Do not stand under the robotic arm; Pay attention to burns when the motor casing is running at high temperatures; Teaching aids are managed by dedicated personnel; After modifying the program/hardware, the new program must prioritize T1 mode testing; Fault handling process (power-off locking, tagging, functional testing after troubleshooting).

Transportation: Maintain transportation posture and avoid impact and vibration.

Put into operation: Change user password before powering on; Check the grounding and plug fastening; Perform a complete set of security function verification; Prevent cable misconnection.

Manual mode (T1/T2): T1 can teach at low speed; T2 high-speed mode prohibits teaching programming; Requirements for personnel working within the protective zone.

Automatic mode: All protective devices are in good condition and can only be operated when there is no one in the danger zone.

Maintenance and repair: power off and lock; Disconnect the main power supply and verify the power before maintenance; After the control cabinet is powered off, there can still be a high voltage of>60V inside for several minutes.

Shutdown, storage, and disposal: comply with local regulations.

Planning

Pre planning reminder: Long term operation at temperature limits, power limits, frequent short cycle movements, and exposure to external process forces will accelerate component wear and require a shorter maintenance cycle. It is necessary to consult with KUKA; The robot will automatically shut down for protection when it exceeds its limit.

Foundation fixation (concrete ground): use chemical anchor bolt components with positioning pins; Concrete grade C20/25; Provide a complete set of installation dimension drawings, base plate, anchor bolt dimensions, concrete edge distance, and thickness requirements.

Transportation

Before transportation, the robot must switch to the transportation posture: A1=0 °, A2=-130 °, A3=+150 °, A4/A5/A6=0 °.
