When the servo screw of a powder packaging machine fails to rotate after power is applied, follow the steps below to identify the cause.
Check all cables and connectors
Confirm that power cables, signal lines, and servo drive connections are tight, undamaged, and correctly connected to the corresponding ports. Poor contact or damaged wiring may prevent the servo screw from starting.
Check the servo controller status
Check whether the servo drive or controller displays any alarm or error code. If a code is shown, refer to the equipment manual to identify the cause and follow the recommended solution. Avoid unnecessary disassembly before confirming the fault.
Check the transmission system
Inspect couplings, bearings, timing belts, gears, and other transmission components for jamming, breakage, or severe wear. If any part is damaged, repair or replace it in time. For certain non-standard transmission parts and connectors, Hansheng Automation provides custom machining based on equipment drawings to help restore normal operation quickly.
By following the steps above, common causes of the servo screw not rotating after power-on can usually be identified. If the problem remains unresolved, it is recommended to contact the equipment manufacturer or a professional technician for further inspection of the motor and drive module.
