Making hydraulic motion controllers for over 30 years. Peter Nachtwey WTF R WE? Making hydraulic motion controllers for over 30 years. Experience with veneer optimizers. Big advancement in late 1999 with the introduction of curve tool for non-linear motion and super imposed move. Advantages since 99 are in processing power, applications, simulations, added features like autotuning and of course, more actual and practical field experience.

"Keep It Going with Better Motion Control Tools" Thursday, October 16, 2014 10:30 -11:00 am Delta is pleased to present at this expo and conference since Forest products have been and continue to be a key industry segment for us and motion control.

Top Maintenance Priorities Get Production back up and Running Finding the cause of a malfunction Doing a quick repair Utilizing better control system tools can quickly solve problems

The Troubleshooting Process Determine whether the problem is in the sensor, controller, actuator, a wiring issue or hydraulic system components. The technician needs good vendor tools and be well versed/trained in both hydraulics and control basics

Advanced Tools Motion control manufacturers strive to provide diagnostic tools for setting up, optimizing, monitoring, and debugging a control system. Tools like Plot Managers, Event logs & Open Loop motion commands are valuable time savers And Advanced Auto tuning techniques.

Sensor Review Start/Stop (good) PWM (good) SSI (best) Use an Oscilloscope Analog (avoid if possible)

Auto-Tuning Works great on good systems Gain Calculator Slider bar to easily choose best gains Auto-tuning The slider bar lets one chose conservative to aggressive gains. The slider bar moves all three PID gains together. The feed forwards are calculated once with the model process and do not change with the slider bar.

"Keep It Going with Better Motion Control Tools" Thursday, October 16, 2014 10:30 -11:00 am Introduction: Good and efficient maintenance is a basic need for high volume manufacturing operations. For the maintenance person, finding the cause of a malfunction and doing a quick repair is the top priority. Utilizing better control system tools can quickly solve problems and get production running after a problem has occurred. The maintenance technician typically needs to determine whether the problem is in the sensor, controller, actuator, a wiring issue or hydraulic system components. In order to quickly resolve the problem, the technician needs good vendor tools and be well versed in both hydraulics and control basics. Today’s motion control manufacturers strive to provide diagnostic tools for setting up, optimizing, monitoring, and debugging a control system. Visual tools, like Delta’s RMCTools Plot Manager Feature, do this with high resolution capture and trend graphs of motion that help troubleshoot sawmill machinery. This tool gives maintenance technicians the ability to quickly and easily determine potential and actual problems. Additionally, event logs and open loop motion commands are valuable time savers along with advanced loop tuning techniques.
