Expert Servo Drive Power Supply Repair Services

Is your servo drive failing to power on, experiencing intermittent power, or shutting down unexpectedly? ROC Industrial specializes in diagnosing and repairing servo drive power supply problems. We offer a fast, reliable, and cost-effective alternative to replacing the entire drive, minimizing downtime and getting your equipment back in operation quickly. We service all major servo drive brands.


Understanding Servo Drive Power Supply Issues


The power supply within a servo drive is a critical component that converts incoming AC power to the DC voltages required by the drive's internal circuitry and the servo motor. Power supply problems can range from complete failure (no power) to intermittent operation and can be caused by a variety of factors.


Common Causes of Servo Drive Power Supply Issues


  • Internal Component Failure:Failed Capacitors: Electrolytic capacitors are common failure points, especially in older drives.
    Failed Rectifiers/Diodes: These convert AC power to DC power.
    Failed Switching Transistors (IGBTs/MOSFETs): These control the flow of power.
    Transformer Failures: (Less common, but possible).
    Faulty Control Circuitry: Problems with the circuits regulating the power supply.

  • External Power Problems:Incorrect Input Voltage: The drive is receiving the wrong voltage.
    Power Surges/Fluctuations: Voltage spikes or dips can damage components.
    Loose Wiring/Connections: Loose wires can interrupt power.
    Blown Fuses

  • Other Internal Drive Failures: A short circuit in another part of the drive (e.g., motor windings) can sometimes cause the power supply to shut down or appear faulty.
