Like was mentioned, making sure you are not too close to the subject with the lens for it to be able to focus is a scenario to avoid if you want your camera to recognize a subject. If you do experience AF focus completion by your K-1/DA200 combo in most cases, there is most likely nothing wrong with the lens overall, otherwise if the AF just does not seem operable in most cases, the lens may be mechanically deficient. The 70-200 is the newer, more advanced lens which was created for the K-1 technologically including the latest functionality/performance features, so it has the advanced edge on any other earlier lenses such as the DA 200 even though the DA 200 may have performed well for past users and still does for present users.

If I were testing the lens in AF.C, I would test it by choosing an object which had contrast, was well lit, not too distant, and was stationary. I would focus on another object first which is at a different distance, then point the camera directly at the stationary test object to so see how fast and accurately the camera focuses on it. If it does (focus reasonably), I would not evaluate the lens as not having the capability to focus on stationary or moving subjects. As in any shooting, moving or not, if you have normal light conditions and you use the proper ISO, shutter speed, and aperture, along with proper tracking by the user of the subject, chances are you are going to get some focused shots with depth and detail. You can set your AF Mode to "Spot", Metering mode to "Spot", "1st Frame Action in AF.C" to "Release Priority", and "Hold AF Status" to "Off" to aid in moving subject shooting while in AF.C.
