Diagnostics and repair
Provide exact machine identity, controller, alarm code, symptoms, recent changes, and production impact.
Request machine serviceMachine service and support
Servo Drive & Motor Fault Diagnosis
Identify the machine, issue, location, production impact, parts need, installation requirement, training need, or warranty question.
Preserve the exact alarm and machine state
Servo faults can originate in the drive, motor, encoder, cable, connector, power supply, braking resistor, mechanical load, coupling, reducer, ball screw, rack, guide, lubrication, tuning, parameters, PLC logic or safety chain.
Information to record
- Machine, controller, axis, drive and motor brand/model/serial number.
- Complete alarm code and text, when it occurs, direction, speed, load and temperature.
- Recent collision, wiring, parameter, battery, motor, drive or mechanical work.
- Whether the axis moves freely under documented safe conditions and whether the fault follows a component swap approved by the manufacturer.
Safety boundary
Do not megger an encoder circuit, disconnect motor or feedback cables while energized, bypass safety, load parameters from another machine, defeat overtravel or repeatedly reset overcurrent, ground, overtemperature or feedback alarms. Stored DC-bus energy and unexpected motion require qualified personnel and documented discharge procedures.
Service pathway
Identify the machine, issue, location, and required next step
Parts and consumables
Provide model, serial number, part number, labels, connectors, quantity, shipping ZIP, and required timing.
Request machine partsInstallation and training
Review site readiness, unloading, placement, connections, startup, acceptance, operator preparation, and follow-up.
