4066

Test move velocity is too high

ABB · ACS850 Standard Program Firmware

What does 4066 mean?

During velocity autotuning, the calculated test move velocity exceeds the configured `DriveSpeedMax` parameter. This indicates a mismatch between the desired tuning speed and the drive's maximum allowed operating speed, which can cause unsafe operation, tuning failures, or unexpected drive trips.

Complete Troubleshooting Guide

  1. 1

    Re-run the commissioning process to ensure all motor and drive parameters are correctly set.

  2. 2

    Check and adjust the `DriveSpeedMax` parameter to an appropriate value for the motor and application, ensuring it accommodates tuning speeds.
