1. What are the most common problems with ABB AC drives?

ABB AC drives are known for their high quality and reliability, but even the best products can have problems from time to time. The most common issues with AC drives are usually caused by human error, so it's important to be aware of these problems and take steps to avoid them.

One of the most common problems with AC drive is incorrect wiring. Incorrect wiring can cause the drive to malfunction or even damage the equipment it's controlling. Another common problem is incorrect settings. Incorrect settings can result in the drive not performing as expected, or even damaging the equipment it's controlling.

By being aware of the most common problems with AC drives, you can take steps to avoid them and ensure the smooth operation of your equipment.

Ensure that the proper motor nameplate information has been programmed into the VFD.

Does the motor nameplate FLA have a higher amperage rating than the VFD?

Has the appropriate VFD been chosen? Torque: Variable or Constant?

Some VFDs have the ability to self-diagnose problems.

Verify that the VFD keypad is showing the correct status (run and speed command) if you have access to it.

If the VFD system provides bypass, the bypass circuit will have an overload device that, if tripped, will also prevent the VFD from connecting to the motor.

Make that the motor is operated in the same direction by the VFD and the bypass mode if you have a bypass option.


Always keep your equipment clean, especially your VFD.

Warmth sinks.

Remove dust with a hoover (DO NOT USE COMPRESSED AIR!).

Air filters for enclosures

Replace the air filters in Type 12 enclosures with cooling fans as needed.

Infrared Scan

In particular, linkages.
