VFD and PowerFlex faults

Call 253-344-1523. An engineer will call you back within 30 minutes in business hours, and come to your plant to find whether the fault is in the drive, the motor, the wiring or the program.

What we will do

Read the fault. We will ask for the fault code on the drive's display, the drive model and what the line was doing when it tripped.

Find the cause, not just the code. A drive fault can come from the motor, the cable, the supply, the load or the settings. A licensed electrician and a controls engineer work on it together.

Get the line running. If the drive has failed, we will source a replacement fast through our distributors, fit it and load its settings.

Write it up. You will get a written site assessment: what failed, what we did and what to fix next.

What we work on

We work on whatever drives are in your plant. Most of what we see is Allen-Bradley PowerFlex and older Allen-Bradley drives, with the motors, cables and networks around them. Tell us the make and model when you call. Need a new drive started up, or spares reformed? See Drive Support.

Behind the engineer who comes

The engineer who comes for your failed drive will work on today's fault. Behind them are the controls engineers, electricians and panel shop that rebuild and upgrade plants and vessels across the Pacific Northwest. If the fault needs another trade, we will send them.

Questions

Should I reset the fault and try again?Once, if it is safe to do so. If it trips again, stop and call: the drive is protecting itself or the motor, and repeated resets can turn a fault into a failure.

What should I tell you when I call?The fault code, the drive's make and model from its label, and what changed before it tripped. A photo of the display and the label helps.

Where and when do you cover?We cover any plant we can reach in a few hours from Fife. Further away, we will try to help you first over a remote connection. If you have an account with us, call 253-344-1523 at any hour and an engineer on call will answer. Without an account, call anyway: if an engineer is free, we will call you back that night or weekend, and if not, from 8 am the next working day.
