Motion Control

Motion Control Overview

Application-Oriented Motion Control Platforms to Fulﬁll a Variety of Control

Requirements

Looking back over decades of PC-based motion control, ASIC-based & distributed control topologies through proprietary bus are quite common. However, the new emerging market

for machine control comes with multiple-axis dependency, synchronization, and improved response times. These factors drive the paradigm shift from ASIC-based to SoftMotion-

based and have more ﬂexibility in design through suitable trajectories aligned with machines to meet the faster throughput, high performance and precision, and real-time Ethernet to

give system integrators and machine builders help ﬁnd the suitable solutions and reduce costs. Combining SoftMotion-based & Ethernet, this paradigm shift helps improve ﬂexible

trajectories, wiring-saving, and faster response times compared with past centralized topologies and reduce system implementation complexity.

Moreover, each quadrant of technology in the following diagram could be integrated into PC-based barebones to provide application-ready motion control platforms with off-the-shelf

utilities and bountiful libraries for vertical market applications. For example, Advantech’s PEC-3240 is a dispensing-oriented controller for the electronic industries.

ASIC-based Motion Control

Since the 1990’s, Advantech has been developing several motion control boards with

ASIC-based technology. Based on the ASIC kernel, the boards are digital signal type and

connected with servo drives and motors to build a system. The pulse train speed and

resolution will determine the control precision and response. Advantech’s motion control

team implemented application-ready libraries to fulﬁll the different machines in industry.

The ASIC-based series boards are for GMC (General Motion Control) purposes to provide

faster time-to-market with robust and cost-effective market adopters.

Distributed Motion Control

As industrial Ethernet technology moves forward to increase response times and accurate

time-deterministic precision, using real-time Ethernet is the future trend and beneﬁts many

machine builders with open standards. Distributed motion control can signiﬁcantly reduce

wiring efforts and cost in signiﬁcant ways. In the past, ﬁeldbus control was proprietary

and had lower response times. Machine builders only have limited options in the market.

However, open standard real-time Ethernet is the next generation. This technology will be

also applied to a variety of Advantech platforms to offer application-ready motion control

platforms with real-time Ethernet technology.

SoftMotion-based Motion Control

In order to meet increasingly demands for complexity of trajectories, such as Gantry

control & synchronization, and voltage signals for speed/torque control, Advantech’s

motion control team developed SoftMotion-based motion controllers and provides

application-oriented & customization services. The SoftMotion technology is a control

kernel executed by software which can run in DSP-based, RISC-based and X86-based

CPUs with real-time extension. This technology gives ﬂexibility in system implementation

and the possibility to integrate third party real-time I/O control boards.

Features and Beneﬁts of Common Motion APIs

Most machine builders and system integrators face library integration headaches from

different vendors and different boards. Moreover, re-programming applications are

necessary when the motion control boards are changed or upgraded. Advantech’s motion

control team delivered the common motion API concept and developed the common

motion library to reduce time-consuming on this task and give faster time-to-market

if any upgrading request exists. The common motion API concept is applied to all of

Advantech’s motion controllers.

Application-Ready Motion Control Platform

In any vertical speciﬁc application, machine builders and system integrators are looking

for application-ready control platforms. The main reasons for this consideration are system

integrity and system stability. Compared with plug-in motion controllers plus industrial

PCs, the application-ready motion control platform provides a well-designed system with

validation to guarantee stability. Furthermore, this concept can bring higher add-on value

to system integrators and machine builders.
