Motion Control

A Broad Array of Products for Centralized Motion Control

Advantech’s full product offering can accommodate all your motion control needs. You can choose from 2-axis and 4-axis controllers, ISA-bus-based or PCI-bus-based, and standard

PC-based or embedded in a system. The functions of the motion cards also vary, from high-end linear/circular interpolation cards to low-cost point-to-point motion devices. And if

you cannot ﬁnd a controller to meet your exact requirements for an embedded motion controller, Advantech is ready to build cost-effective controllers to meet your criteria, whether it

be adding digital I/O channels or changing connector styles, or perhaps changing CPU grade. With all the inherent costs, time and risks involved, there’s no reason why you should

design your own controller when you can instead rely on the expertise, cost-efﬁciency, experience and proven reliability of Advantech.

The Differences Between Centralized & Distributed Motion Control

Machine control system architectures generally fall into two categories - centralized or distributed. In a centralized system, all control loops including logic, trajectory generation,

and PID control, are executed on a single processor. In a distributed system, the trajectory generation and logic control executes in the central processor, but the PID control loop is

executed in the intelligent slave module. A distributed approach gives moreprocessing power, while it reduces overall wiring cost and system complexity.

The Distributed Motion Control Products are categorized in two groups - Master Cards and Slave Modules. Communication between master and slave is based on a custom-engineered

technology based on RS-485, which saves wires, transmits over long distances at high speeds, and has time-deterministic features.

The communication interface between master and host PC is based on memory mapping. Various functions can be chosen on the slave modules, and the industrial DIN-rail mountable

design makes it easy to distribute them in the ﬁeld. The master card collects information from slave modules and publishes the data to its host PC, and vice versa.

Motion Control Overview

SoftMotion-based Motion Control

Advantech develops DSP-based SoftMotion control cards which enable the simpliﬁed

utilization of complex motion manipulation involving JOG, PTP, linear and circular

interpolation, multiple axes synchronized motion, and etc. For highly ﬂexible programming

features, it has the possibility to offer motion kernel customization. For high performance

FPGA, high execution rate DSP, and Dual-Port RAM (DPM) technology, SoftMotion

control cards can support faster encoding speeds, higher speed position comparison, and

trigger pulse outputs over cards which use ASIC motion IC. SoftMotion controllers can

provide programmable acceleration and deceleration to eliminate jerk and smooth velocity

proﬁle. For each axis, individual unlimited point tables can realize seamless continuous

movements. These tables are also able to combine linear and arc segments. Based on

the Common motion API—DSP & FPGA architectures, Advantech provides customers

much easier programming environment and robust motion control.

Compact Size Robust Design Advanced Motion Control Multiple Interfaces

Application-Ready Motion Control Platforms - PEC Series

Advantech provides embedded motion control platforms for embedded motion applications. PEC series is 1/8 the size compared with standard industrial computers, even with built-in

motion control and digital I/O, Analog input functionalities, greatly saving space and development time. Fanless, no internal cables, and diskless mechanisms allow PEC series to

operate under -10 ~ 65°C (14 ~149°F) without any heat issues. Due to its PC-based computing architecture integrated with motion control and digital I/O, PEC series can handle a wide

range of devices under test (DUT), such as touch panel proﬁles very quickly, greatly reducing development time. Its small size allows it to ﬁt into space-constrained applications and its

anti-vibration capabilities allow PEC series to withstand vibration and noise interference during veriﬁcation processes. To meet different demands for industrial automation, PEC series

provides a variety of motion control functions, such as 2/3-axis linear, 2-axis circular interpolation, continuous interpolation, T/S-curve speed proﬁle and software limits. PEC series

features USB ports, COM (RS-232) ports, 10/100 Base-T LAN ports, and CompactFlash slots. These interfaces provide the capability to easily expand peripheral devices and modules.
