Delta Motion RMC 75E & S

Delta Motion RMC75E CPU & Red Lion G315 HMI:

​​Advanced Motion Control Computer, managed by advanced Human-Machine Interface.

This unit may control 2 axes or two wave generators.


All position data for the wave generators is calculated mathematically in real time  where  wave parameters are inputted manually at the HMI   Nearly infinite possibilities of wave character are possible.

There are no stored curves; however, non-random curves will repeat exactly each time specific parameters for a wave sequence is selected.

HMI communicates via Ethernet/IP to the CPU. The DeltaRMC75E CPU links to the LinMot drives via digital IO and Analog, managing PID Closed loop feedback directly with the drive.

Omron's NJ CPU and the Omron HMI

This CPU communicates with up to three motor drives: Two running EtherCAT and one Ethernet/IP


Delta Motion RMC75S CPU & Red Lion G308 HMI:

The Delta RMC75S  & the Red Lion G308

Both are less expensive, and communicate via RS232

Delta Motion RMC75E CPU & Red Lion G306 HMI:

Communicating via Ethernet

Siemens S7 1200 CPU & HMI:


A simple PLC and HMI


... Used to select up to 100 pre-created curves which were programmed into the LinMot drive.  These curves may be modified by changing parameters at the HMI.


Random Sea is not possible because of the limited amount of time available for each curve. Regular waves are simply repeats of a single stored curve.


Types of stored curves would include Regular Waves, Rogue Wave, Tsunami, and a short running Random simulation

PC SOFTWARE - DAC - LinMot Drive  The Admin setup for   Museum or School

Computer and Digital to Analog Converter  (DAC)

Here the entire Human Interface is a Touch Screen monitor, a PC.  A  Windows 7 PC Laptop is the primary controller of the wave generating system. 

A DAC (Digital to Analog Converter) with USB connection to the PC, running software (C++, C#, etc. which controls the DAC) generates the analog signal which the LinMot Drive uses to position a LinMot linear motor, which makes the desired waves.



Using the TOUCHSCREEN Monitor

Select any of the four types of waves that can be generated by touching the screen


Adjust the wave height  (inches) and period (seconds)


Start wave, software will stop it after a predetermined number of waves have run.


Two Modes of Operation

In  "Admin Mode" The Software is designed to be run by an expeienced ocean science teacher or experimentor.   in the "Museum Mode"  the public makes any wave type and can view what happens with coastal and/or floating models.

However, in "Museum Mode" there are built in limitations to what the wave generator may be commanded to do.



The software can start a video camera, and playback in slow motion to match the real time of wave action



Chart Recorder

A chart recorder might display the actual signal being sent to the wave generator


Red Lion HMI Controls the LinMot Motor without a PLC or Motion Controller - Another Low cost system for a  Museum or School

In  Using only Rs-485 for the communication interface, the HMI calls and modifies stored curves in the LinMot drive.  All waves are possible; Regular, Random, Rogue and Tsunami

The System: Motor, Drive, Power Supplies and the HMI...
