The 1391 Series Allen Bradley drives are still in use on many machines throughout industries, especially automotive, aerospace, food production, wood products and conveyor-type systems. A stout servo drive system, the 1391 comes in both analog and digital. Here, we will look at the analog side, but it’s meanings are the same in digital.
Today we have an Indramat HVR02.2-W010N power supply in for repair. After a static check, we connect power to the unit to confirm the fault. It is then disassembled; and taken to our wash-down area for a full cleaning and bake, before we begin the repair. This unit came from a parts manufacturer in Detroit and experienced a voltage spike which burned up incoming line voltage.Â

Indramat HDS drive system will flash an error code when not working correctly.
#1Â Code F208/UL
Description: If a servo motor or a different drive has been changed out for the original unit in the loop, due to troubleshooting or an upgrade.
Solution: This is fairly simple. After powering up and code is registered, hitting reset on the drive and power supply, then cycle power and unit should be functional. Â
Maintaining an up-to-date copy of the software in your HMI can save your machine.
