30030

All controller errors cleared (_ecCONTROLLER_ERRORS_CLEARED)

ABB · ACS850 Standard Program Firmware

What does 30030 mean?

This is an informational message in the error log, indicating that all previous controller-related errors have been cleared. It's a status notification, not an active fault.

Common Causes

  • A user manually issued an ERROR_CLEAR command for controller-level faults from the HMI, PLC, or drive's diagnostic interface.
  • The control system automatically cleared controller faults after a power cycle or successful resolution of an underlying issue.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    This is an informational message, no direct action is required. Review the drive's error log for any previous controller-specific fault codes that were cleared to understand their root causes.

  2. 2

    If this message appears frequently, investigate the control program for automated error clearing routines (e.g., ERROR_CLEAR command) that might be inadvertently clearing and masking transient controller issues.

  3. 3

    Ensure that the controller's fault log is routinely backed up or archived before clearing to maintain a historical record for diagnostic purposes.
