PLC / Drives, Motion & Axis Diagnostics
Diagnose an axis following error through command and feedback evidence
An axis can lag its commanded trajectory because of load, tuning, feedback, drive limits or mechanical constraints.
Environment and inputs: Industrial PLC / automation guidance · Verify the exact controller, module, firmware, engineering tool and machine documentation. Linked vendor examples apply to their stated products and library versions; observation, state changes and physical work require distinct authorization.
Observe and record
Compare approved recorded command, actual feedback, drive limits and the exact fault timing with the motion profile.
Interpret the evidence
A following-error threshold is not a tuning target to enlarge automatically. Invalid feedback can mimic a mechanical or performance problem.
Resolve and verify
Repair the demonstrated feedback, mechanical or supported control issue through the qualified owner and validate the intended operating envelope safely.
Machine and data safeguards
Do not increase error limits or torque settings merely to prevent a trip.
