Chapter 1 Overview
Introduction
The DMC-40x0 Series are Galil’s highest performance stand-alone controller. The controller series offers many
enhanced features including high speed communications, non-volatile program memory, faster encoder speeds, and
improved cabling for EMI reduction.
Each DMC-40x0 provides two communication channels: high speed RS-232 (2 channels up to 115K Baud) and
10BaseT Ethernet. The controllers allow for high-speed servo control up to 22 million encoder counts/sec and step
motor control up to 6 million steps per second. Sample rates as low as 31.25
µ
sec per axis are available.
A Flash EEPROM provides non-volatile memory for storing application programs, parameters, arrays and firmware.
New firmware revisions are easily upgraded in the field.
The DMC-40x0 is available with up to eight axes in a single stand alone unit. The DMC-4010, 4020, 4030, 4040
are one thru four axes controllers and the DMC-4050, 4060, 4070, 4080 are five thru eight axes controllers. All
eight axes have the ability to use Galil’s integrated amplifiers or drivers and connections for integrating external
devices.
Designed to solve complex motion problems, the DMC-40x0 can be used for applications involving jogging, point-
to-point positioning, vector positioning, electronic gearing, multiple move sequences, and contouring. The
controller eliminates jerk by programmable acceleration and deceleration with profile smoothing. For smooth
following of complex contours, the DMC-40x0 provides continuous vector feed of an infinite number of linear and
arc segments. The controller also features electronic gearing with multiple master axes as well as gantry mode
operation.
For synchronization with outside events, the DMC-40x0 provides uncommitted I/O, including 8 opto-isolated digital
inputs (16 inputs for DMC-4050 thru DMC-4080), 8 high power optically isolated outputs (16 outputs for DMC-
4050 thru DMC-4080), and 8 analog inputs for interface to joysticks, sensors, and pressure transducers. The DMC-
40x0 also has an additional 32 I/O at 3.3V logic. Further I/O is available if the auxiliary encoders are not being used
(2 inputs / each axis). Dedicated optoisolated inputs are provided for forward and reverse limits, abort, home, and
definable input interrupts.
Commands can be sent in either Binary or ASCII. Additional software is available for automatic-tuning, trajectory
viewing on a PC screen, CAD translation, and program development using many environments such as Visual
Basic, C, C++ etc. Drivers for Windows XP (32 & 64 bit).
