DriveProgramming Error (User Trip)

What does E50. to E59. mean?

This error indicates that a user-defined trip condition within the DriveProgramming logic has been met, causing the inverter to shut down. This is an intentional protective action programmed into the custom sequence, not an internal hardware fault. The specific cause is defined by the user's program logic.

• A specific user-defined condition (e.g., motor current exceeds X for Y seconds, external input Z goes low, internal timer expires) programmed within the DriveProgramming sequence has been met, triggering the trip.
• An unexpected state or value in the machine process that violates the programmed safety or operational limits defined in the DriveProgramming logic.
• Incorrect scaling, offset, or thresholds defined in the DriveProgramming logic for monitored variables (e.g., analog input values).
• Input signal connected to a DriveProgramming trigger (e.g., digital input terminal) is behaving erratically or unexpectedly, falsely meeting a trip condition.

Click steps to track your progress.

1. 1

   Identify the specific E5X.X fault code (e.g., E50.0, E51.1) to pinpoint which user-defined trip condition was met within the DriveProgramming logic.

2. 2

   Upload the DriveProgramming sequence to the programming software and locate the corresponding trip condition (e.g., an IF/THEN statement that issues a user trip command).

3. 3

   Monitor the status of the variables and inputs (e.g., motor current, digital input state, internal timers) that are part of the tripping logic, using the inverter's monitor menu (e.g., U1-XX).

4. 4

   Review the historical fault log for associated events or parameters that may have led to the condition being met just prior to the E5X.X trip.

5. 5

   Adjust the threshold or timing parameters within the DriveProgramming logic if the trip condition is too sensitive or based on incorrect assumptions about the process behavior.
