A feedback fault on a Bosch servo axis rarely proves the encoder is defective on its own. This triage route treats the encoder, cable, shield, supply, mechanical coupling and drive interface as one signal path, so UK engineers can separate a genuine encoder failure from an installation or EMC problem before fitting a replacement.
When a 400 V motor on a retrofitted drive fails at the bearing after eighteen months, the workshop verdict is usually mechanical wear. More often the damage was electrical, invisible to routine vibration monitoring, and sourced from the inverter. This checklist sets out what to measure, what to fix and what to record.
Bosch drives already expose current, torque, running hours and often a kWh counter, yet many UK plants still buy separate meters for every reporting line. This guide shows how to turn drive parameters into a defensible kWh-per-product figure, where the uncertainty lies, and what the data should never be used for.
Resetting a fault and restarting is standard practice, but the drive's fault history is a reliability record waiting to be used. This article explains what to export and trend from Bosch drives, and how recurring alarms can become scheduled maintenance actions rather than post-mortem notes.
