Kernel overload

What does 64E1 mean?

An operating system error indicating that the drive's internal kernel (core operating system) is experiencing an overload. This is a severe internal fault preventing normal drive operation and cannot be reset by the user. It points to a critical issue with the drive's core processing capabilities.

• Excessive number of high-priority interrupts or real-time tasks overloading the kernel.
• Inefficient or buggy kernel modules causing CPU hogging.
• Malfunctioning hardware component generating continuous interrupts (e.g., I/O chip).
• Insufficient processing power for the configured drive complexity (e.g., too many control loops, high sample rates).
• Kernel memory corruption due to hardware instability or software defects.

Click steps to track your progress.

1. 1

   Perform a power cycle of the drive by disconnecting input power for 60 seconds.

2. 2

   Reduce the sampling rates or update frequencies of critical control loops (e.g., lower P3-01 to 2ms from 1ms).

3. 3

   Simplify complex control strategies running within the drive application.

4. 4

   Update the drive firmware to the latest stable version, which may include kernel optimizations.

5. 5

   Disconnect any non-essential I/O or communication modules (e.g., remove FBA A) and retest.

6. 6

   Monitor the drive's internal CPU load (e.g., parameter P1-50) if available in diagnostic view.
