The mitigation of harmonic current distortion is a challenging problem facing our Utilities and the Engineers designing today’s energy efficient buildings. ABB’s Harmonic Analysis Tool helps you meet the challenge. We make this as easy as 1, 2, 3.
This document explains how to enable and adjust the motor pre-heat function in the drive, as well as the advantages of using the VFD pre-heat motor functionality compared to using a traditional motor winding heater.
Tech Note 089: THHN wire for HVAC and water drives
THHN wire is sometimes used on the output side of a VFD, between the drive and motor. While ABB allows THHN to be used for HVAC and water VFDs, we do not recommend it be used. This technical note reviews the concerns of THHN wire along with other solutions that are more appropriate for use with a VFD.
Tech Note 085: Control panel backups in 580 series
The 580 series drive control panel can store multiple drive backup files and restore the information as directed. This technical note is an expanded explanation of the drive control panel backup and control panel restore functions.
Tech Note 081: PID setpoint over GP1 (FLN), N2, and BACnet
This document provides guidance on what point/object to write to over GP1 (FLN), N2, or BACnet to adjust the setpoint in a PI(D) loop. The document details specific parameters that need to be adjusted.

Tech Note 073: Active front end drive versus passive filter
There are several options when looking to mitigate harmonics in a system. This document compares two of the current technologies to mitgate harmonics in variabe frequency drives, Active front end drives, and passive harmonic filters. The document shows the strengths and concerns of each technology and how they can apply to different scenarios to meet site compliance.
The technical note reviews the evolution of the UL 508C standard and the harmonization to the new UL 61800-5-1 standard. Specifically, the changes to the investigation and testing requirements for Power Conversion Equipment and the resulting impact on ratings for short circuit current (SCCR).
Troubleshooting serial communication issues on drives may occasionally require verification that the the drive's EFB is functional. To do this, a laptop computer can be used with software programs loaded onto the computer. This Technical Note details two Modbus programs and two BACnet programs that can be used to verify the drive's EFB port is functional on an ACH580 drive.
