Drive Programming User Trip (0 to 9)

What does E50-E59 mean?

These faults are generic user-defined trip codes triggered by specific conditions programmed within the Drive Programming application (E50 corresponds to user trip 0, E51 to user trip 1, etc.). They allow technicians to implement custom safety or operational interlocks, causing the inverter to trip and display a user-defined error code when those conditions are met.

• A specific condition defined by the user in the Drive Programming (DP) logic has been met (e.g., motor current exceeded X for Y seconds, sensor input below Z).
• External sensor input exceeding or falling below a predefined threshold, as monitored by the DP program.
• Timer or counter within the DP program reaching a programmed limit, triggering the user trip.
• Logical error in the DP program that unintentionally triggers the user trip condition under normal operating parameters.
• Fault in an external device (e.g., pressure sensor, level switch, flow meter) whose status is monitored by the DP program.

1. 1

   1. Identify which specific user trip (0-9, corresponding to E50-E59) was triggered and review the corresponding Drive Programming (DP) logic that generates that trip.

2. 2

   2. Determine the precise condition(s) programmed to activate the user trip; for example, if P5-01 (Motor current) > 150% of nominal for 5 seconds.

3. 3

   3. Verify the actual state of the input(s) or monitored parameters that are checked by the DP program (e.g., measure current, check sensor status, evaluate timer value).

4. 4

   4. Adjust the threshold or logic in the DP program if the trip condition is found to be too sensitive or inappropriate for the application.

5. 5

   5. Check for faults in external sensors or equipment that provide inputs to the DP program, ensuring their readings are accurate.
