We work on older, hydraulically powered, multi-axis systems, so we have a big interest in them not all converting entirely to electrically powered alternatives. By sharing a pump across many axes of motion, we believe we can keep our per-axis cost in line with any solution. We'd like to hear what tips readers have for ensuring a well-tuned hydraulic system with emphasis on the controls and the embedded sensors.

Send us you comments, suggestions or solutions for this problem. We'll include it in the June '12 issue. You can comment here or email us at controldesign@putman.net. Please include your company, location and title in the response.
