RMP EtherCAT Controller Features

Streaming PVT Motion – Our motion controller includes several very powerful streaming motion options which enabled our customer to stream coordinated multi-axis moves to all the robot joints in order to move in an X, Y, Z, reference frame.

Real-time IO trigger – The customer is leveraging User Limits to trigger digital outputs in a deterministic manner based on the axis encoder position.

Performance and Reliability – When the application can not fail, our customer trusted our high-performance motion controller. RMP runs using a RTOS core provided by Tenasys inside Windows OS environment. The RTOS CPU core is dedicated to RMP EtherCAT motion firmware.

RTOS Integration – Our customer is running our motion controller with INtime alongside Windows. This architecture is paramount when latency times, performance, and reliability are critical. In addition, the motion firmware runs in a real-time deterministic manner.

Solution Provided by RSI

Motion Controller – Customer is using RMP EtherCAT motion controller due to multi-axis synchronization. In addition, RMP has helped the customer stream multi-axis motion trajectories in a real-time deterministic manner. In this scenario the OEM used cam profile for their machines.

Software – The customer has developed in-house CNC software in collaboration with ArtSoft’s Mach software. Customer leverages RSI’s intuitive RapidCode software libraries (programmable in C++ and C#) to reach production quickly.

Controls Hardware – The customer uses several types of EtherCAT compatible servo drive and motor products.

IO Hardware – The customer selected Beckhoff EK1100 series modules because it is easy to add more modules based on machine’s IO requirements.
