Failures We Repair Frequently

Below are the issues we resolve every day in our shop for this exact model:

• Overvoltage Faults: High DC bus voltage from excessive braking or power instability.
• Undervoltage Alerts: Line power dips or missing phase inputs resulting in shutdowns.
• Current Spikes: Trip conditions caused by bad motor wiring, shock loads, or short circuits.
• Heatsink Overheat: Triggered by airflow blockage, high ambient temps, or internal failure.
• Stall Detection: Motor fails to start or rotate, often due to incorrect torque/load settings.
• Braking Resistor Trips: Resistor overload from excessive deceleration frequency or resistance mismatch.
• Brake Switch Fault: Internal brake circuit failure from repeated heavy decel cycles.
• Communication Timeout: HMI or controller loses signal with the drive — often a logic board issue.
• STO (Safe Torque Off) Error: Faulty STO board input causing unwanted drive disablement.
• Control Section Error: Internal comm fault between main processor and gate drive circuitry.
• Feedback Faults: Encoder or speed sensor failure resulting in overspeed or unstable output.
• Current Limit Protection: Drive halts when output exceeds configured safety limits.
• Auxiliary 24V Fault: Shorted or overloaded 24V output circuit.
• Phase Loss Detection: Missing power leg or faulty internal rectification triggering a trip.
• DESAT Trip: Overcurrent shutoff at IGBT level — often a power stage board replacement is needed.
• Ripple Voltage Issues: Abnormal voltage ripple from input filtering or phase mismatch.
• Brake Short Circuit: Detected short in braking path either external or inside the drive.
• Overspeed Condition: Drive exceeds max speed limits — typically encoder or feedback instability.
• Analog Input Fault: Signal error in 0–10V or 4–20mA input range — due to wiring or config mismatch.
• Low-Speed Overcurrent: High amp draw at near-zero speed due to poor flux settings or load binding.
• Motor Overheat Trip: Triggered by sustained high torque, incorrect voltage, or thermistor wiring issues.
