Ethernet motion controllers sizzle with
speed
The DMC-40x0 Ethernet/RS232 controller family is the latest addition to the ultra-high-speed Accelera range of controllers.
New from Galil Motion Control, the DMC-40x0 Ethernet/RS232 controller family is the latest addition to the company's ultra-high-speed Accelera range of controllers This augments Galil's DMC-18x6 PCI controllers which spearheaded the launch of the successful Accelera series last year

Galil Motion Control updates Motion Control Product Catalogue for 2006 with the latest specifications and pricing for its controllers and drives.
Library speeds motion control system programming
HelloGalil is a new library of quick-start projects for communicating between Galil motion controllers and PC programming languages.
The Accelera series represents Galil's 5th generation of motion controllers which are notable for their powerful, 32bit RISC-based microcomputer that delivers much higher speed and processing power than previous generation controllers.
"These Accelera controllers sizzle with speed", explains Lisa Wade, VP-Marketing and Sales, Galil.
"They accept encoder inputs at frequencies up to 22MHz, provide servo update rates as high as 32kHz, and execute program instructions within 40us".
The DMC-40x0 is a packaged, full-featured motion controller that operates in a stand-alone configuration or interfaced to a PC via its Ethernet 10/100Base-T or RS232 ports.
The controller is available packaged with multi-axis drives which eliminates the need for external, separate drives and minimises wiring.

Easy to use interface for any automation project
The new SCADA Portal from ABB is an easy-to-use graphical interface for controlling remote processes from small, standalone applications to five clients and up to 10,000 I/O per server
The first multi-axis drive product for the DMC-40x0 is the AMP-43040, a four-axis amplifier for driving brush or brushless servomotors up to 500W.
Future product releases will include drives for stepper motors.
The DMC-40x0 comes in one- through eight-axis formats and, like all Galil controllers, lets the user purchase only the number of axes required.
For example, a DMC-4030 would be specified for a three-axis project, a DMC-4050 for a five-axis project, and so on.
Users are also able to synchronise multiple controllers for applications with more than eight axes; and can easily mix-and-match motor types in an application since each axis is user-configurable for stepper or servomotor operation.
The new controller handles virtually any mode of motion including: point-to-point positioning, position tracking, jogging, linear and circular interpolation, contouring, electronic gearing and ECAM.
Advanced commands for co-ordinated motion include ellipse scaling, slow-down around corners, infinite segment feed and feedrate override.
Precise motion control is achieved with advanced PID compensation, velocity feedforward, acceleration feedforward, integrator limits, notch filter, low-pass filter, backlash compensation, and servo update rates as high as 32kHz.
The DMC-40x0 also provides expanded memory for up to 510 symbolic variables, 16,000 array elements in 30 arrays, and application program space for up to 2000 lines x 80 characters.
It allows multitasking for simultaneously running up to eight programs and fast I/O processing for precisely synchronising motion with external events.
The new controller includes both digital and analogue I/O for interfacing to external sensors.
Standard, optically isolated inputs for each axis include a forward limit, reverse limit and homing input.
The controller also features eight uncommitted isolated inputs and 8 uncommitted isolated outputs for the one- to four-axis models, and 16 inputs and 16 outputs for the five- to eight-axis models.
Isolated outputs are high power for driving brakes or relays.
In addition to isolated I/O, the DMC-40x0 provides 32 x 3.3V I/Os.
The DMC-40x0 also has eight uncommitted analogue inputs which allow the controller to interface with analogue sensors such as joysticks and temperature sensors.
Inputs from two separate encoders are accepted for each servo axis.
The DMC-40x0 is compact and measures just 206 x 184 x 44mm for the one- to four-axis models and 292 x 184 x 44mm for the five- to eight-axis models.
The controller and drive unit operates from a single 20-80V DC supply.
Signals are accessible through convenient D-type connectors.
Like all Galil controllers, the Accelera Series use Galil's popular, English-like command language for easy programming, and has communication drivers available for all current versions of Windows, Linux and NET.
Galil's popular WSDK servo design software simplifies system set-up with "one-button" servo tuning and real-time display of position and velocity information.
The DMC-4040 four axis controller is $2295 in single quantity and $1195 in 100 quantities, and the DMC-4080 eight-axis controller is $3195 in single quantity and $1795 in quantities of 100.
