Common Parker Servo Drive Problems We Repair

Parker servo drives are built to be durable, but like all electronic equipment, they can experience failures over time. We specialize in diagnosing and repairing common issues that affect Parker servo drives.

  • No Output: The servo drive fails to provide any power to the motor, preventing it from operating.

  • Overvoltage Errors: The drive detects excessive voltage levels, triggering a fault and shutting down.

  • Undervoltage Errors: The drive detects insufficient voltage levels, triggering a fault and shutting down.

  • Communication Errors: The drive loses communication with the controller, resulting in a loss of control.

  • Overheating: The drive overheats due to excessive load, inadequate cooling, or component failure.

  • Blown Fuses: Fuses blow due to power surges, short circuits, or component failures within the drive.

  • Encoder Faults: The encoder, which provides feedback on motor position, malfunctions, leading to inaccurate control.

  • Brake Resistor Failure: The brake resistor, used to dissipate energy during deceleration, fails, causing braking issues.

  • Drive tripping on overcurrent: The drive detects excessive current draw, triggering a fault and shutting down.

  • Inconsistent performance: The servo drive operates erratically or fails to maintain consistent performance.

  • Positioning errors: The servo drive is unable to accurately position the motor.

  • Speed fluctuations: The servo drive experiences speed fluctuations or instability.

  • Unusual noises: The servo drive emits unusual noises, such as humming, buzzing, or grinding.

  • Component failures: Internal components, such as capacitors, resistors, or transistors, fail.
