Track Motion Error - Path Deviation

ABB Robotics Robot Critical Robot

Model: ABB IRB 2600 Robot | Code: ABB 10021

Applicable Systems

IRB 2600 IRB 4600 IRB 6700 IRB 1200 IRC5 Controller

Symptoms

Robot path deviation exceeds tolerance during motion; robot stops; programmed path not achieved.

Step 1: Check if payload shifted or is loose on end-effector
Payload secure
Step 2: Verify counterbalance pressure (if equipped)
Pressure within spec
Step 3: Run servo tuning wizard for current payload
Tuning completes, motors respond well
Step 4: Check for mechanical play/backlash in joints
No excessive play
Step 5: Re-run program and verify path accuracy
Path within tolerance

Reset via FlexPendant; may require servo tuning update.

Q: How often to tune ABB robot servos?
After payload change, after mechanical maintenance (gearbox/motor replacement), or if path accuracy degrades. Use IRC5 tuning wizard.
