RTOS Overrun Warning

What does A00600 mean?

This warning indicates an internal time slice overrun within the drive's Real-Time Operating System (RTOS). This typically points to an internal processing delay, excessive computational load, or a software anomaly that could affect system stability and performance.

• Excessive computational load on the drive's Real-Time Operating System (RTOS) due to complex control tasks or multiple active functions.
• Firmware bug or corrupted software module causing an infinite loop or excessive processing time in a specific task.
• Degradation of internal clock source or timing hardware, leading to incorrect task scheduling.
• Internal memory corruption or resource exhaustion preventing tasks from executing within their allocated time slices.
• A high-priority interrupt is continuously active, monopolizing CPU resources and preventing other tasks from running.

Click steps to track your progress.

1. 1

   1. Reduce the drive's internal pulse frequency (e.g., P1800) or disable non-critical functions to lighten the CPU load.

2. 2

   2. Check for and install the latest firmware updates for the drive, as software bugs causing RTOS overruns are often addressed in patches.

3. 3

   3. Review the drive's active control modes and optional functions (e.g., complex technological functions, fieldbus communication rate) for potential bottlenecks.

4. 4

   4. Perform a parameter reset (e.g., P0010=30, P0970=1) to clear any potentially corrupted configuration and then re-commission essential parameters.

5. 5

   5. Monitor the drive's internal CPU load (if available via diagnostics, e.g., r0034) to pinpoint when the overrun occurs.
