galilmcEthernet/RS232 Accelera Series, 1–8 axes

Product Description

The DMC-40x0 motion controller is Galil’s highest 

performance, stand-alone motion controller. It

belongs to Galil’s latest generation motion controller

family: the Accelera Series, which accepts encoder

inputs up to 22 MHz, provides servo update rates 

as high as 32 kHz, and processes commands in as fast 

as 40 microseconds—10 times the speed of prior

generation controllers.

The DMC-40x0 is a fullfeatured motion controller

packaged with optional

multi-axis drives in a compact,metal enclosure.The

unit operates stand-alone 

or interfaces to a PC with

Ethernet 10/100Base-T 

or RS232.The controller

includes optically isolated 

I/O, high-power outputs capable of driving brakes or

relays, and analog inputs for interfacing to analog 

sensors.The DMC-40x0 controller and drive unit accepts

power from a single 20–80 VDC source.

The DMC-40x0 is available in one through eight axis

formats, and each axis is user-configurable for stepper

or servo motor operation. Standard programming 

features include PID compensation with velocity and

acceleration feedforward, multitasking for simultaneously running up to eight programs, and I/O processing

commands for synchronizing motion with external

events. Modes of motion include point-to-point positioning, position tracking, jogging, linear and circular

interpolation,contouring, electronic gearing and ECAM.

Like all Galil controllers, the DMC-40x0 controllers use

Galil’s popular, English-like command language, which

makes them very easy to program. Galil’s WSDK servo

design software further simplifies system set-up with

“one-button” servo tuning and real-time display of

position and velocity informatio
