ABB Robot Error 10023 – Encoder Signal Instability: Causes and Fix
⚠️ Quick Fix for ABB Error 10023
If this error appears, try these immediate actions:
- Restart the ABB IRC5 Controller using FlexPendant
- Check encoder cables for loose shielding or poor grounding
- Ensure connectors are tight and free of corrosion
- Reduce nearby electrical interference sources
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.
What Does ABB Error 10023 Mean?
Error 10023 indicates that the encoder signal is present but unstable, unlike:
- 10020 → Signal lost (no signal)
- 10022 → Signal out of range (invalid signal)
👉 10023 = Signal exists but is noisy / fluctuating
This may result in:
- Position drift
- Unstable axis motion
- Unexpected robot stops
Affected components include:
- Encoder feedback system
- Signal cables and shielding
- Drive modules
- Axis motors
Common Causes of ABB Error 10023
Poor Cable Shielding or Grounding
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.
Electrical Noise / EMI Interference
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.
Loose or Corroded Connectors
Intermittent connections cause signal fluctuation.
Aging or Failing Encoder
Encoder internal components degrade over time.
Cable Damage (Internal Breaks)
Partial wire damage leads to unstable signal transmission.
Drive Module Signal Processing Issues
Drive unit may incorrectly interpret encoder signals.
How to Troubleshoot ABB Error 10023
Step 1: Restart the Controller
- Reset via FlexPendant
- Observe if issue is intermittent
Step 2: Inspect Encoder Cable Shielding
- Ensure shielding is intact and properly grounded
- Avoid routing near high-power cables
Step 3: Check Connectors
- Tighten all connectors
- Clean corrosion or oxidation
Step 4: Reduce Electrical Interference
- Separate signal cables from power cables
- Check grounding system integrity
Step 5: Inspect Encoder and Motor
- Check encoder condition
- Replace if signal instability persists
Step 6: Test Drive Module
- Swap or test drive unit if possible
- Verify signal processing
Step 7: Perform Calibration
- Recalibrate axis after fixing signal issues
- Verify stable feedback values
Related Components That May Be Affected
- Encoder units (absolute/resolver)
- Shielded feedback cables
- Drive modules
- Grounding system
When Should You Replace Components?
Replacement is recommended if:
- Signal instability persists after cable and grounding fixes
- Encoder shows inconsistent readings
- Connectors are damaged or worn
- Drive module fails to process signals correctly
