DriveWorksEZ Fault 2

¿Qué significa dWF2 ?

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.

• Logical error in the DriveWorksEZ custom program (e.g., calculation overflow, incorrect variable assignment, invalid state transition).
• Improperly defined conditions or transitions in state machine logic within the DriveWorksEZ program, leading to unexpected paths.
• Race condition or timing error in the DriveWorksEZ program when handling multiple concurrent events or asynchronous inputs.
• External input signal (e.g., from digital input S1) unexpectedly changing state, triggering an erroneous program path not handled by logic.

1. 1

   Connect to the drive using DriveWorksEZ software and access the fault trace log to identify the specific program line or condition that triggered the fault.

2. 2

   Review the DriveWorksEZ program logic, especially sections related to the 'Fault 2' specific condition if documented, for calculation errors or incorrect conditional statements.

3. 3

   Step through the DriveWorksEZ program logic in simulation mode or with an attached debugger (if available) to observe variable states and program flow.

4. 4

   Verify the state of all external inputs (e.g., S1, S2) and analog inputs (e.g., A1) referenced in the program using the drive's monitor display (e.g., U1-01, U1-02).

5. 5

   Download a previously working version of the DriveWorksEZ program to the drive and observe if the fault clears. If so, identify changes made.
