Servo drive repair process at Repair Zone

For this process, our technician will use a customer’s Allen Bradley 1391B-AA45 Drive.

Hello, I am one of the electronic technicians at Repair Zone.  Today I am going to explain our remanufacturing process.

Normally, when your drive comes in for repair, we perform static tests to see if anything shorted or any obvious damage, and then we put your drive on a test cart to test the operations and see if we can duplicate your problems.

But, in a case with a drive like this, with heavy contamination, the first thing we want to do is to completely disassemble it and wash and dry it with an environmentally safe cleaner to remove any contaminants that would cause problems when power is applied to the drive.

During the washing process, we visually inspect all components of the drive for any physical or heat related damage, so we can give those areas special attention to check for any possible damage.

Once the excess water is blown off, we place the drive in the oven to dry for several hours to make sure all water is removed from the components.

When the drive comes out of the oven that is when we begin the repair process.  We replace any components we have identified as an issue, and we also replace any components that we have seen as a common failure on the drives, including electrolytic capacitors and fans.  We perform as many static tests as we can on each of the individual circuits as part of our repair process.

Once the repair is completed, we reassemble the drive and place it on the test stand, where we try to simulate as many functions as your machine as possible, including actually running a motor with the drive before we ship it out.

Once the drive has passed all of our test processes, it is sent over to the shipping department, who will package it up and send it off to another satisfied customer.

We take your downtime seriously at Repair Zone!
