Safety related maximum velocity exceeded

What does F7020 mean?

The motor's actual velocity has exceeded a safety-related maximum velocity limit. This is a critical safety function (e.g., Safe Maximum Speed) designed to prevent the axis from ever exceeding an absolute safe operating speed, regardless of commanded values, to avert machinery damage or injury.

• Failure of speed control loop or drive power stage, leading to uncontrolled acceleration.
• External forces driving the motor beyond its safe speed.
• Incorrectly configured safety-related maximum velocity parameter (e.g., S-0-0XXX Safe Max Velocity).
• Faulty speed feedback (encoder) giving erroneous high-speed readings.

Click steps to track your progress.

1. 1

   Immediately verify and re-calibrate the motor encoder to ensure accurate speed feedback.

2. 2

   Check the configured safety-related maximum velocity parameter in the IndraDrive; ensure it is set correctly and appropriately for the application.

3. 3

   Inspect the mechanical system for any external forces or loads that could cause the motor to overspeed.

4. 4

   Review the drive's control loop tuning and stability.

5. 5

   If the problem persists and external factors are ruled out, the drive's speed control or power section may be faulty and require service.
