ABB Robot Error 10116 – Axis Encoder Drift: Causes and Fix
⚠️ Quick Fix for ABB Error 10116
If this error appears, try these immediate actions:
- Check encoder or resolver cables for loose or damaged connections
- Inspect servo drive for feedback anomalies
- Perform a manual axis test to detect mechanical resistance
- Restart the ABB IRC5 Controller via FlexPendant
ABB Robot Error 10116 – Axis Encoder Drift occurs when the ABB IRC5 Controller detects that the axis position feedback from the encoder is drifting or out of expected range, which can cause motion inaccuracies or protective stops.
What Does ABB Error 10116 Mean?
Error 10116 indicates that:
- Encoder readings do not match expected axis positions
- Position feedback drifts beyond allowed tolerance
- Controller triggers an alarm to prevent unsafe motion
This typically results in:
- Axis stopping unexpectedly
- Inaccurate positioning during tasks
- Repeated alarms if encoder drift persists
Typical Symptoms
- Unexpected axis stops or jerky motion
- Servo drive indicates feedback error
- Inconsistent trajectory during operation
- Alarm appears during precision or repetitive tasks
Common Causes of ABB Error 10116
Encoder or Resolver Issues
Encoder drift is often caused by faults in the encoder or resolver feedback system.
Common issues include:
1. Worn or failing encoder
2.Loose or damaged signal cables
3.Electrical interference or signal corruption
Regularly inspect encoders for wear and ensure cables are secure to maintain accurate feedback.
Mechanical Wear or Misalignment
Mechanical wear such as bearing or joint issues can lead to backlash, causing the encoder feedback to drift.
Common issues include:
1. Worn bearings or joints
2. Gearbox wear leading to position errors
Inspect mechanical components for wear and lubrication issues to ensure smooth movement.
Servo Drive or Motor Issues
- Overheating affecting signal accuracy
- Drive module malfunction
Motion Programming Problems
- High speed or acceleration settings exaggerating feedback errors
- Incorrect payload compensation
External Disturbances
- Unexpected collisions or forces affecting axis
- Electromagnetic interference
How to Troubleshoot ABB Error 10116
Step 1: Inspect Encoder and Resolver
- Check for loose connections or damaged cables
- Ensure proper alignment and signal integrity
Step 2: Check Mechanical Components
- Inspect joints, bearings, and gears for wear or friction
- Lubricate or repair as needed
Step 3: Monitor Servo Drive
- Check for overheating or fault LEDs
- Review drive logs for abnormal torque or feedback errors
Step 4: Review Motion Program
- Reduce speed and acceleration
- Adjust path profiles and payload compensation
- Avoid abrupt motion commands
Step 5: Reset and Test
- Reset alarm via FlexPendant
- Perform controlled axis movement
- Observe if encoder drift persists
Step 6: Replace Components if Needed
- Replace encoder or resolver if drift continues
- Replace servo drive or motor if feedback issues persist
- Repair mechanical components causing backlash or resistance
Related Components That May Be Affected
