Why verify motion directions during commissioning?
Hoist up/down and any trolley/bridge directions are matched against pendant markings and actual movement. Incorrect direction is investigated through phase/connection, control or circuit logic.
What path is traced when the pendant does not work?
Emergency stop and supply, control voltage, pendant buttons, limits, contactor/drive, brake and motor circuit are assessed in motion sequence.
What else is observed in a functional check?
Brake release/holding behaviour, limit functions, abnormal sound/vibration, cable routing and operator visibility are reviewed according to the application.
What should a fault video show?
Record the command being pressed, equipment response, panel/receiver indicators, any displayed fault code and the equipment nameplate in a short sequence to improve remote pre-assessment.
