dLF

Dynamic Load Error

Schneider Electric · Altivar Machine ATV320 Variable Speed Drive

What does dLF mean?

A detected error related to the dynamic characteristics of the load. This could be an unexpected change in motor load, resonance, or mechanical issues affecting the motor's operation, which the drive's control system cannot compensate for.

Complete Troubleshooting Guide

  1. 1

    Inspect the mechanical system for binding, loose couplings, excessive wear, or obstructions.

  2. 2

    Verify motor auto-tuning results and re-perform the procedure if necessary.

  3. 3

    Adjust the drive's acceleration/deceleration ramps and S-curves to match the load dynamics.

  4. 4

    Check for sudden load changes or external disturbances impacting the driven equipment.
