Understanding ABB ACS560 Warning AFF6 Identification Run Guide

Seeing AFF6 on your ABB ACS560? Don’t Panic!

If you are setting up a new ABB ACS560 drive and the code AFF6 starts flashing on the screen, your first instinct might be to think something is wrong. 

 

Here is the good news: AFF6 is not a fault. It is an informative warning. It’s the drive’s way of saying, “Okay, I’ve got your motor data, now I’m ready to perform the Identification (ID) Run. Just give me the signal!”

What exactly is the AFF6 Warning?

The AFF6 Identification Run warning appears when you have selected an ID Run type in parameter 99.13. The drive is now in a "standby" mode. It has paused all other operations and is waiting for you to press the Start button so it can measure the motor’s electrical characteristics.

Why is the AFF6 code appearing?

Usually, this happens during one of two scenarios:

• New Commissioning: You are setting up the drive for the first time.
• Motor Parameter Changes: You recently changed data in Group 99 (Motor Data), and the drive automatically decided it needs a new ID Run to stay accurate.

How to Clear AFF6 and Complete the ID Run

To get rid of the AFF6 code and return the drive to normal operation, you must complete the ID Run process. Follow these simple steps:

Step 1: Verify Your Settings

Before you hit start, ensure that Parameter 99.13 (ID Run Request) is set to the mode you want:

• Normal: Best accuracy (requires the motor to be uncoupled from the load).
• Still: Used if the motor is connected to a machine and cannot rotate.

Step 2: Check for Safe Conditions

Ensure that it is safe for the motor to rotate (if you chose Normal/Reduced run). Check that the Enable (Safe Torque Off) signal is active and there are no external interlocks stopping the drive.

Step 3: Press Start

Simply press the Hand/Green Start button on the control panel.

• The AFF6 warning will stay on the screen while the run is in progress.
• The motor might make a high-pitched humming sound—this is normal!
• Once the drive has finished its measurements, it will stop automatically, and the AFF6 code will disappear.

What if AFF6 won't go away?

If you press Start and nothing happens, check these three common "human" errors:

1. Control Location: Make sure the drive is in "Local" mode (check the top of the screen). If it's in "Remote," it might be waiting for a signal from a PLC that isn't coming.
2. STO (Safe Torque Off): If your emergency stop is pressed, the drive cannot start the ID Run.
3. Faults: If a fault (like FF61) appears after you press start, you'll need to troubleshoot the motor data you entered.

Summary

The ABB ACS560 AFF6 warning is just a bridge between entering your motor data and running your machine. It’s a sign that the drive’s internal brain is ready to optimize itself for your specific motor. Just check your safety, hit Start, and let the drive do the hard work.
