Chapter 1 Overview

Introduction

The DMC-1600 series motion control cards install directly into a compact PCI bus. This
controller series offers many enhanced features including high speed communications, non-
volatile program memory, fast encoder speeds, and improved cabling for EMI reduction.
The DMC-1600 provides two communication channels: a high speed FIFO for sending and
receiving commands and a secondary channel which gives high speed access to status and
parameters. The DMC-1600 allows for high speed servo control up to 12 million encoder
counts/sec and step motor control up to 3 million steps per second. Sample rates as low as
62.5μsec per axis are available.
A 2 Meg Flash EEPROM provides non-volatile memory for storing application programs,
parameters, arrays and firmware. New firmware revisions are easily upgraded in the field without
removing the controller from the system.
The DMC-1600 can be used with step motors, servo motors, and hydraulics, on any combination
of axes. Each axis is configurable by the user for optimum flexibility.
The DMC-1600 achieves superior precision through use of a 16-bit motor command output DAC
and a sophisticated PID filter that features velocity and acceleration feedforward an extra pole
filter, and integration limits. Designed to solve complex motion problems, the DMC-1600 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-1600 provides continuous vector feed of an infinite number of linear
and arc segments. The DMC-1600 electronic gearing mode features operation for multiple
masters axes as well as gantry.
For synchronization with outside events, the DMC-1600 provides uncommitted I/O, including 8
general use digital inputs, 72 general use digital outputs, and 8 analog inputs for interface to
joysticks, sensors, and pressure transducers. Dedicated optoisolated inputs are provided for
forward and reverse limits, abort, home, and definable input interrupts. The DMC-1600 is a plug
and play device making it easy to set-up. Commands can be sent in either Binary or ASCII.
Additional software is available to autotune, view trajectories on a PC screen, translate CAD.DXF
files into motion, and create powerful, application-specific operator interfaces with Visual Basic.
Drivers for Dos, Windows 3.1, 95, 98, 2000, ME, XP and NT are available.
