Indramat DKC drives are part of the ECODRIVE collection. ECODRIVE was designed to provide economical industrial automation for factory applications like handling, packaging, and assembling. The DKC 02.3 drive works with servo motors like the Indramat MKD.
The Indramat DKC02.3 drive is one of 2 SERCOS DKC drives (the other being the highly uncommon DKC22.3). These drives use the open SERCOS protocol, and can be used with any SERCOS control.
The DKC02.3 is recognizable by the SERCOS Tx (labeled X20) and Rx port (X21).
If you have a problem with your DKC 02.3, chances are good that none of the engineers on the floor will have experience with troubleshooting for this component. It was probably put in place before most of them were born.
Check your cables first — just change out the current cable or cables with a new one. Sometimes this solved the problem. Over the years, the cabinets may be moved around and people may step over or on the cables. The connection can weaken. You don’t want to experience the feeling you get when you replace your drive and then find out that the cable is the problem.
Another thing to check is the distortion indicator, or H2) light. This is an LED light labeled “H20.” It has nothing to do with water. Instead, it checks every node to make sure it is receiving the right optical load.
The H20 light gives the indication that the light energy coming into the drive is outside optimum parameters, but I have seen them run for years in this condition. One result: your team thinks that light means the power is on, or something like that. When the unit fails, no one thinks about that H20 light.
Make the sure the transmission rate and transmission power are set correctly. And if you didn’t check the fiber optic cables before, check them now, because a faulty cable can get that h20 light glowing.
