4066

Test move velocity is too high

ABB · Application Error ABB Motion Drives Error trouble shoo

What does 4066 mean?

During velocity autotuning, the calculated velocity exceeded the configured DriveSpeedMax parameter. This indicates that the DriveSpeedMax parameter might be set too low or the autotuning process is attempting an excessively fast move.

Common Causes

  • The DriveSpeedMax parameter is incorrectly set to a value lower than the required velocity for the test move.
  • Autotuning process attempting to reach a speed beyond the application's physical limits.
  • Incorrect motor or application scaling causing velocity miscalculation during autotuning.
  • Inconsistent drive parameter settings between motor data and operational limits.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Re-run the commissioning process for the drive and carefully review the DriveSpeedMax parameter.

  2. 2

    Ensure that the DriveSpeedMax parameter is set to a value that is appropriate for both the motor and the application's mechanical limits.

  3. 3

    Check that commanded drive speed limits are not excessively high for the system.

  4. 4

    Verify other relevant motor and application scaling parameters to ensure consistency.
