CANopen Servo Drives

CANopen® is a robust and low cost serial protocol that offers enhanced diagnostic and control capabilities with medium-level bandwidth. While older than some other networks, it remains a favorite among many motion control designers. And no, it has nothing to do with electric can openers; it’s a highly configurable ‘open’ protocol based on CAN (Controller CANopen Servo Drives

EtherCAT Servo Drives

EtherCAT® is a high performance Ethernet based deterministic network protocol developed by Beckhoff. It is industry proven to deliver high-speed, deterministic control with standard 100 base-T hardware and achieve blazing fast, consistent results in demanding applications. EtherCAT is an open technology which means everybody may use, implement and benefit from the technology. As a result, EtherCAT EtherCAT Servo Drives


RS-485 is similar to RS-232, but with higher speeds, multi-drop capability and differential signaling. Benefits RS-485 is faster and more noise immune than RS-232 Capable of connecting more than two devices (multi-drop) Low cost network solution ADVANCED Motion Controls’ Capabilities Configuration and control interface for many DigiFlex® Performance™ drives using ADVANCED Motion Controls’ proprietary serial object library 921.6 kbit/sec RS-485


Ethernet POWERLINK is an open, real-time protocol that runs on Ethernet hardware. Created by B&R, this open standard leverages CANopen device profiles for drives, CiA-402. POWERLINK is designed to give users a single, consistent, and integrated means for handling all communication tasks in modern automation. A POWERLINK network integrates all automation components such as PLCs, Ethernet POWERLINK

Ethernet (UDP and TCP)

Ethernet UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) are the basic communication protocols of the internet. They can also be used as communications protocol in private networks. Choosing which internet communication protocol to implement comes down to whether you want data transmitted quickly or reliably. TCP Transports data reliably by authenticating that all Ethernet (UDP and TCP)


  100BASE-T is any of several Fast Ethernet standards for twisted pair cables with 100 Mbit/s transmission speed, allowing full-duplex transmission. Benefits 100BASE-T is a universal hardware standard with easy availability to compatible devices ADVANCED Motion Controls’ Capabilities Custom DigiFlex® Performance™ drives have been offered with 100BASE-T as the underlying hardware standard for communication Industries, Technologies, and 100BASE-T

Modbus (RTU or TCP)

Modbus RTU is a network of field devices using serial communication. Sensors and devices can be daisy-chained in a network. Extremely popular for industrial control networks. Modbus TCP is an Ethernet extension of Modbus – “Modbus protocol in a TCP wrapper”. Benefits Open standard / open source Royalty free Lightweight implementation Easy migration from Modbus Modbus (RTU or TCP)

J1939 (CAN)

SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components by the car and heavy-duty truck industry in the United States. Benefits Under J1939/11 and J1939/15 the baud rate is specified as 250 kbit/s with J1939/14 specifying 500 kbit/s Excellent reliability error detection and fault confinement ADVANCED Motion Controls’ J1939 (CAN)
