DriveWorksEZ Fault 3

What does dWF3 mean?

This fault signifies an error within the DriveWorksEZ program, indicating a logical or programming issue rather than a drive hardware fault. The program logic is causing an unexpected condition, preventing proper operation. Continued attempts to run without correcting the program could lead to incorrect machine behavior or unexpected stops.

• Specific logical error in the DriveWorksEZ custom program (e.g., division by zero, array out-of-bounds access, stack overflow).
• Incorrectly configured conditional branches or loops leading to an infinite loop or unexpected program termination.
• Over-utilization of CPU resources by complex or inefficient DriveWorksEZ program blocks, leading to an internal watchdog timeout.
• Conflicting write operations to the same parameter or memory location from different parts of the DriveWorksEZ program.

Click steps to track your progress.

1. 1

   Connect to the drive using DriveWorksEZ software and inspect the fault register or diagnostic logs for clues about the specific fault condition (e.g., stack trace).

2. 2

   Carefully examine the DriveWorksEZ program for complex arithmetic operations, loop conditions, or state machine transitions that could lead to unexpected states.

3. 3

   Isolate and comment out sections of the DriveWorksEZ program to determine which part is causing the 'Fault 3' error.

4. 4

   Monitor relevant internal program variables and parameters (e.g., P7-01 to P7-04 for program status) using DriveWorksEZ during operation to pinpoint the failure point.

5. 5

   Ensure the DriveWorksEZ program does not exceed memory or execution limits. Simplify logic or split into subroutines if necessary.
