SAM/SBR limit exceeded

¿Qué significa C01706 ?

The limit for Safe Acceleration Monitoring (SAM) or Safe Brake Ramp (SBR) has been exceeded. This indicates that the motor braking response is not within the parameterized tolerance, posing a risk of uncontrolled deceleration and potential mechanical damage or safety hazard.

• Actual acceleration or deceleration of the motor exceeded the configured limits for Safe Acceleration Monitoring (SAM) or Safe Brake Ramp (SBR) (e.g., p9580, p9581).
• Mechanical issue on the load side (e.g., sudden load drop, seized bearing) causing an uncontrolled acceleration or insufficient braking.
• Drive control loop instability or incorrect tuning (e.g., p1460, p1462 for speed controller gain) leading to overshoot in speed or torque.
• Incorrect encoder feedback (e.g., noise, loose connection) providing erroneous speed or position data, causing the SAM/SBR function to misinterpret motion.

1. 1

   1. Verify the configured limits for Safe Acceleration Monitoring (p9580) and Safe Brake Ramp (p9581) are appropriate for the application's dynamics and load.

2. 2

   2. Inspect the mechanical system for any issues (e.g., binding, excessive inertia changes, brake malfunction) that could lead to unexpected acceleration/deceleration.

3. 3

   3. Check the motor feedback system (e.g., encoder connection, signal integrity on X130) for noise, intermittent signals, or incorrect pulses.

4. 4

   4. Review and tune the drive's speed controller parameters (e.g., p1460, p1462) to improve dynamic response and prevent overshoots.

5. 5

   5. Perform a safety reset (e.g., via p9699 or cycling safety inputs) after confirming the actual motion adheres to the defined SAM/SBR limits.
