Appendix C: An Example
Example Setup & Tuning of a Hydraulic System
This illustrated step-by-step example covers setting up and tuning a hydraulic
position axis. This example uses a hydraulic system set up for position/pressure
control, but will only treat the position portion. For a position/pressure example,
see the online help.
This example uses an RMC101-M1-A1-ENET, a common configuration for
position/pressure control. The system itself is a hydraulic cylinder with MDT
feedback (start/stop rising edge).
1. System Design
A typical hydraulic system for position/pressure control looks like this:
Note the good design practices:
• Metal tubing between valve and cylinder.
• An accumulator close to valve.
• Use of a zero-overlap valve.
2. Wiring
It is important to wire the transducer correctly. See the wiring section in this
document for details.
For this example the system is wired as follows:
• The position feedback is wired to MDT channel 0.
• The MDT Drv 0 is wired to the valve.
3. RMCWin View
When connected to this RMC, the main RMCWin window looks as follows:
Index/position-pressure
transition/position-pressure
