F7020

Safety related maximum speed exceeded

Bosch Rexroth · IndraDrive MPx02

Hva betyr F7020 ?

This safety technology error indicates that the actual speed of the motor, as monitored by safety functions, has exceeded the defined safety-related maximum speed limit on the IndraDrive MPx02. This is a critical safety violation, indicating an uncontrolled overspeed condition that requires an immediate safety shutdown.

Vanlige årsaker

  • Incorrectly parameterized safety-related maximum speed (e.g., S-0-0091 'Maximum velocity') for the application.
  • Loss of speed control due to incorrect tuning of the velocity loop or external disturbances.
  • Encoder fault or noise leading to erroneous speed feedback.
  • Commanded speed exceeding the configured safe maximum limit.
  • Mechanical drive failure or external forces causing uncontrolled motor rotation.

Reparasjonssteg & Sjekkliste

Klikk på steg for å spore fremgangen.

  1. 1

    Review and adjust the safety-related maximum speed parameter (e.g., S-0-0091) in the IndraDrive MPx02, ensuring it aligns with the machine's safety limits and operational requirements.

  2. 2

    Check the tuning of the velocity control loop for stability and accuracy, specifically proportional (Kp) and integral (Ki) gains.

  3. 3

    Verify the motor encoder for accurate and consistent speed feedback. Inspect wiring for damage, loose connections, or electromagnetic interference.

  4. 4

    Analyze the commanded motion profile and the application's dynamics to ensure that no operational condition leads to exceeding the safe maximum speed.

  5. 5

    Inspect the mechanical system for any binding, excessive backlash, or external forces that could cause the motor to overspeed.
