Chapter 1 Overview

Introduction

The DMC-21x5 series is the latest in Galil's Econo line of motion controllers and is an upgraded version of the
popular DMC-21x3 series controller. The controller series offers many enhanced features compared to prior
generation controllers including high speed communications, non-volatile program memory, faster encoder
speeds, and improved command processing.
The DMC-21x5 is available with up to eight axes in a single stand alone unit. The DMC-2115, 2125, 2135, 2145 are
one thru four axes controllers and the DMC-2155, 2165, 2175, 2185 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-21x5 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-21x5 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-21x5 provides uncommitted I/O, including 8 digital inputs (16
inputs for DMC-2155 thru DMC-2185), 8 outputs (16 outputs for DMC-2155 thru DMC-2185), and 8 analog inputs
for interface to joysticks, sensors, and pressure transducers. Further I/O is available if the auxiliary encoders are
not being used (2 inputs / each axis). Dedicated inputs are provided for forward and reverse limits, Abort, home,
and definable input interrupts.
A Flash EEPROM provides non-volatile memory for storing application programs, parameters, arrays and firmware.
New firmware revisions are easily upgraded in the field.
Commands are sent in ASCII. Additional software is available for automatic-tuning, trajectory viewing on a PC
screen, and program development using many environments such as Visual Basic, C, C++ etc.
