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.
