KUKA KR QUANTEC-2 HC Maintenance and Rescue Guide

Zero point loss: replace motor, add brake RDC、 After the encoder battery or collision occurs, it is necessary to recalibrate the zero point. After calibration, test under T1 first.

Stop distance becoming longer or brake noise: Check the wear, load, speed, and STOP 0 triggering times of the main brake and auxiliary brake. Replace the brake or motor if necessary.

Overheating or Overload: Check if the load data is entered correctly, if the tool's center of gravity and inertia exceed the limit, if the ambient temperature is too high, if the gear oil is aging, and if the maintenance cycle is overdue. If the oil temperature exceeds 60 ° C, the maintenance interval should be shortened.

Abnormal security function: All security functions must be tested regularly. Enable the switch to be checked at least once every 12 months. The patient rescue function is tested annually. After the safety function or protective device is disabled, it must be immediately restored and functional testing must be conducted.

Stopping distance and safety

The stopping distance and stopping time are related to the load, program multiplier, range of action, and type of shutdown. Under KR C4, the KR 300 R2700-2 HC stops at a distance of approximately 35.24 ° and a stop time of approximately 0.82 seconds for A1, 18.66 ° and 0.44 seconds for A2, and 15.79 ° and 0.32 seconds for A3 at 100% operating range, 100% POV, and rated load. Under KR C5, at STOP 0, A1 stops at a distance of approximately 22.12 ° and 0.58 seconds for A2, 11.69 ° and 0.35 seconds for A2, and 9.87 ° and 0.21 seconds for A3. Regular retesting should be conducted on site based on load, speed, and brake wear, and it is recommended to check at least once a year.

Storage and Disposal

Before long-term storage, move the robot to the transport position (A1 0 °, A2-135 °, A3 150 °, A4 0 °, A5-105 °, A6 0 °), remove tools and accessories, clean and dry, seal electrical interfaces and hose joints, cover with film and seal the base to prevent dust, and place desiccants if necessary. The storage environment should be dry, dust-free, and avoid temperature differences, wind, condensation, and direct sunlight.

When disposing of waste, materials are classified as cast iron parts, copper cables, light metal castings, steel parts, electronic components, motors, plastic parts, etc. Hydraulic and pneumatic balance cylinders must be professionally depressurized in advance and are only allowed to be disposed of in a non pressurized state. Gear oil, hydraulic oil, and lubricating grease should be handled according to the requirements of the safety data sheet.

Overall, the stable operation of KUKA KR QUANTEC-2 HC relies on standardized installation, regular inspection of patient rescue systems, timely maintenance of additional brakes, correct load data, regular oil changes, and balancing cylinder pressure checks. On site engineers should incorporate transportation posture, foundation fixation, grounding, oil change volume, torque value, patient rescue testing, and T1 testing into standard operating procedures to reduce downtime risks, extend robot lifespan, and ensure patient and operator safety in medical environments.
