⚠️ Quick Fix for ABB Error 10023
If this error appears, try these immediate actions:
Intermittent signal issues are often resolved with wiring checks.
ABB Robot Error 10023 – Encoder Signal Instability occurs when the ABB IRC5 Controller detects fluctuating or inconsistent encoder feedback signals, making accurate position tracking unreliable.
Error 10023 indicates that the encoder signal is present but unstable, unlike:
👉 10023 = Signal exists but is noisy / fluctuating
This may result in:
Affected components include:
Unstable encoder signals often result from inadequate shielding or grounding of the encoder cables.
Common issues include:
1.Insufficient grounding of signal cables
2.Damaged or worn cable shielding
3. Interference from surrounding electrical systems
Ensuring high-quality shielding and proper grounding restores signal stability.
Electromagnetic interference (EMI) from high-power equipment can disrupt encoder signal transmission.
Common sources include:
1.Welders, VFDs, and motors operating nearby
2.Power cables running parallel to encoder cables
3. Poorly shielded electrical systems
To minimize interference, keep encoder cables away from high-power sources and use effective shielding.
Intermittent connections cause signal fluctuation.
Encoder internal components degrade over time.
Partial wire damage leads to unstable signal transmission.
Drive unit may incorrectly interpret encoder signals.
Replacement is recommended if:
Unstable encoder signals can lead to precision loss and production downtime:

ABB Robot Error 10023 – Encoder Signal Instability indicates fluctuating feedback signals that prevent accurate position tracking. The most common causes include poor shielding, electrical interference, loose connectors, or aging encoders.
By improving wiring quality, reducing interference, and replacing faulty components, engineers can restore stable and precise robot operation.
It is typically caused by electrical noise, poor shielding, loose connectors, or failing encoders.
Check shielding, grounding, connectors, reduce interference, and replace faulty components.
10022 = signal out of range; 10023 = signal unstable/fluctuating.
Yes, electromagnetic interference is one of the most common causes.
