Acceleration threshold exceeded

What does F7014 mean?

This safety technology error indicates that the actual acceleration of the motor has exceeded a safety-related acceleration threshold configured in the IndraDrive MPx02. This is a critical safety violation, implying an uncontrolled or excessively rapid change in speed, leading to an immediate safety stop.

• Incorrectly parameterized safety-related acceleration threshold (e.g., S-0-0092 'Maximum acceleration') for the application.
• Aggressive tuning of the speed or current control loops, causing overshoot during acceleration/deceleration.
• Mechanical shock or sudden load change causing high acceleration.
• Encoder fault or noise leading to erroneous acceleration calculation.
• Commanded acceleration exceeding the safe limit for the selected operating conditions.

Click steps to track your progress.

1. 1

   Review and adjust the safety-related acceleration threshold parameters (e.g., S-0-0092) in the IndraDrive MPx02, ensuring they are appropriate for the application's safety requirements.

2. 2

   Check the tuning of the current and velocity control loops, specifically feed-forward and gain settings, to prevent overshoot.

3. 3

   Inspect the mechanical system for any sudden load changes, binding, or play that could induce high acceleration spikes.

4. 4

   Verify the motor encoder for accurate feedback, as noisy position data can lead to erroneous acceleration calculations.

5. 5

   Analyze the commanded motion profile to ensure that programmed acceleration ramps do not exceed the safety threshold.
