Safety related maximum speed exceeded

¿Qué significa 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.

• 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.

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.
