The scenario is common across industrial America: An aging machine begins to experience electrical glitches. Longer lead times for maintenance calls and a shrinking pool of experienced service providers becomes increasingly problematic. Controls begin to wear out, causing machine downtime and scrapping in-process materials. Knowing the machine still has a

useful life ahead, and with the price tag for a replacement in the six-figure range, management seeks a fix that’s viable in the long run.

For more than a century, large ships have used stabilizing fins to smooth out their ride through rolling seas. The force that fins produce is related to the angle of the fin
and the speed of the vessel through the water. Fin systems are typically moved by hydraulics and require active control. They are designed to use the speed of the sea water (while the ship is under way) to generate stabilizing force. This same force must be overcome by the hydraulics if the fin is to change direction.

Delta announces a new feature in Delta's RMC family of motion controllers that simplifies tuning in multi-axis sinusoidal cyclic testing applications with servo hydraulics. By implementing easy-to-modify user programs within Delta's RMCTools software, a testing process can now perform adaptive phase control as well as amplitude and offset control.

Delta is pleased to announce that Peter Nachtwey, Delta's President, was invited to deliver a technical presentation at the Fluid Power World Technical Conference at the Milwaukee School of Engineering (MSOE) in Milwaukee Wisconsin during June 21 and 22, 2016. This presentation will be focused on testing applications and is titled Cyclical testing in fluid power applications: Why frequency matters in sinusoidal testing.

Tim Gessner, Software Engineer

Please join us in welcoming back Tim Gessner, now known as Dr. Tim. Tim is a California native who learned to love the Pacific Northwest summers during his early years, worked in business systems, ERP and CRM systems prior to joining Delta in 2000 as a software development engineer. He initially contributed to RMCWin improvements, then the development of the RMC75, RMC150 and RMCTools. In 2011 he left to pursue a PhD in Theology at the University of Edinburgh in the United Kingdom. That 4 year UK experience added to his Bachelors and 2 Masters Degrees in Theology. Tim and his wife Doreen returned to the Pacific Northwest late in 2015, to be near their son and daughter and fortunately returned to Delta during a key phase of product development.
