Next level hydraulic control Delta RMC75 1 or 2-Axis Delta RMC150 Up to 8-Axis Delta RMC200 Up to 32-Axis acceleration and jerk (i.e, the rate of change in acceleration) without needing to do low- level machine programming. “Initially, I had some concerns with utilising the more complex features of the RMC like camming and advanced gearing,” said Shindledecker. “But I made a trip to the Delta factory and worked with a Delta engineer for a week on this project. This was very helpful.” The same RMCTools environment supports all of Delta’s current RMC motion controllers. “The software compatibility between the RMC150 and the RMC200 work out very well,” said Shindledecker. “It helped us reduce the programming time required for this product by letting us re-use motion steps in newer machines that we’ve used before.” RMCTools is also useful for troubleshooting, with a key component of the package being the Plot Manager. This is a tool that allows various motion parameters such as axis position, velocity, and hydraulic pressure to be plotted in real time and compared with target values produced by the control algorithm. The output is displayed on the screen of an attached PC or saved in a file for later review or archiving purposes. Besides actively controlling motion axes, Delta motion controllers can connect to additional transducers for the purpose of monitoring other status points on the machine. “The RMC200 has now given us what we have been asking for,” says Jenkins. “With up to 32 axes available we can now control all of our hydraulic axes plus gather diagnostic information.” “The functionality of this machine would be extremely difficult to accomplish without the use of the Delta RMC200,” concludes Shindledecker. www.deltamotion.com RIGHT: Figure 3. The motion controllers in Delta Computer Systems’ RMC family all use the same RMCTools programming, documentation, and tuning tools.
