Analysis of common technical problems of industrial robots

-- [YM ROBOT] expert team to solve your problems

1. Accuracy Drift & Path Deviation

Symptoms

Millimeter error in weld/assembly position

Repeat positioning accuracy exceeds nominal value (e.g. ±0.1mm → ±0.5mm)

Root Causes

✔ Mechanical Wear: Harmonic reducer/gearbox life expiration (usually 6-8 years)

✔ Temperature Effects: No preheating or ambient temperature fluctuation more than ±5°C.

✔ Load Imbalance Payload Issues: Failure to calibrate the TCP or overloading of the end tool.

Quick Diagnostic Package: 3D trajectory analysis with ABB RobotStudio® 2.

2. Communication Interruption/Loss of Signal | Communication Failures

Communication Failures | High Frequency Failure Scenarios Common Scenarios

DeviceNet/Profibus signal intermittent (85% due to poor grounding)

Robot cannot exchange IO data with PLC

Prevention Tips

✔ Use shielded twisted-pair (STP) cable with a single point of grounding.

✔ Avoid parallel routing with inverter cables (>30cm spacing)

3. Singularity Alarms

Why is the 6-axis robot "stuck"?

When 4/5/6 axes are close to the same line, the inverse kinematics cannot be solved mathematically.

4. Post-Collision Recovery | Post-Collision Recovery

Wrong operation vs.

Don't: reboot directly → may lead to secondary damage

✔ Our standard service procedure:

Torque sensor data diagnosis

Harmonic reducer backlash detection

All-axis servo gain tuning

5. New Age Challenge: Digital Twin Desynchronization | Digital Twin Desynchronization

Why is the virtual world "out of sync" with reality?

Physical sensor data delay >50ms

CAD model not updated with actual wear
