KUKA LBR iiwa CR Cleanroom Troubleshooting and Maintenance

Robot not moving but no alarm: Check if T1/T2/CRR is holding down the enable button, Start button, if the program is in jog mode, safety door signal, external enable, and if the single point control SPOC parameters have been modified by online tools.

Communication or data cable issues: Check whether the bending radius of the data cable is not less than 45 mm, whether it is in the metal cable tray, whether it is stretched, whether the joint is locked, and whether the control box WX55/X55, WX65/X65, WXE1 connections are connected.

Mechanical looseness or damaged locating pin: Check the torque of 4 screws, locating pin, base ring seal, foundation load, cleanliness of installation surface, and vertical installation to avoid pin damage.

Automatic shutdown when the temperature is too high: check the ambient temperature, duty cycle, continuous high load, heat dissipation conditions, fan operation, and temperature sensor alarm. After cooling, it can be restarted without any additional measures.

Collision or overload: Check whether the torque sensor, load map, mass inertia, tool center of gravity, and additional load exceed the limit. If there is abnormal noise or decreased accuracy after collision, the motor and mechanical structure must be checked.

Dismantling, replacement, and storage

Before dismantling, move the robot to the transport position, turn off the power, unplug the connecting cable, open the control box, remove 4 M4x8 screws, 4 Allen screws and locating pins, protect the joints and hoses from contamination, lift the robot together with the base ring, and place it in the transport box. Reinstall in reverse order: set the positioning pin, lower the base ring, lower the robot, cross tighten the screws, connect the exhaust duct, connect the data cable and grounding, check that the cable is not stretched or rubbed, and finally install the tools and energy supply.

Long term storage requirements: dry, dust-free, avoid temperature fluctuations, avoid wind, avoid condensation, use appropriate coverings, leave no loose parts, avoid direct sunlight, comply with storage temperature, and choose a location that will not damage the packaging. Clean and dry before storage, conduct internal and external inspections, remove foreign objects and corrosion, install cover plates and seals, seal electrical and hose connections, and place them in the transport box.

Classify by material during disposal: aluminum outer structure, base ring, control box shell; Stainless steel shielding plate, screws, washers; Copper cable; Steel screws and pins; Electrical components such as fans, boards, and optocoupler modules shall be treated as electrical scrap, and the motor shall not be disassembled; Plastic ABS terminal box, elastomer seal, PA cable joint, PUR/PVC/rubber cable sheath. The safety data sheet for auxiliary materials should be requested from the manufacturer.
