PMAC2A-PC104 Hardware Manual

Introduction 1

INTRODUCTION

Overview

The PMAC2A-PC/104 motion controller is a compact, cost-effective version of the Delta Tau’s PMAC2

family of controllers. The PMAC2A-PC/104 can be composed of three boards in a stack configuration.

The baseboard provides four channels of either DAC ±10V or pulse and direction command outputs. The

optional axis expansion board provides a set of four additional servo channels and I/O ports. The optional

communications board provides extra I/O ports and either the USB or Ethernet interface for faster

communications.

Board Configuration

Base Version

The base version of the PMAC2A-PC/104 ordered with no options provides a 90mm x 95mm board with:

• 40 MHz DSP563xx CPU (80 MHz 560xx equivalent)

• 128k x 24 internal zero-wait-state SRAM

• 512k x 8 flash memory for user backup & firmware

• Latest released firmware version

• RS-232 serial interface

• 4 channels axis interface circuitry, each including:

• 12-bit ±10V analog output

• Pulse-&-direction digital outputs

• 3-channel differential/single-ended encoder input

• 4 input flags, 2 output flags

• 3 PWM top-and-bottom pairs (unbuffered)

• 50-pin IDC header for amplifier/encoder interface

• 34-pin IDC header for flag interface

• PID/notch/feedforward servo algorithms

• 1-year warranty from date of shipment

• One CD-ROM per set of 1 to 4 PMACs in shipment (Cables, mounting plates, mating connectors not

included)

Option 2A: PC/104 Bus Stack Interface

Option 2A provides the PC/104 bus interface allowing bus communications between a PC/104 type

computer and the PMAC2A-PC/104 motion controller.

Option 5xF: CPU Speed Options

• Option 5CF: 80 MHz DSP563xx CPU (160 MHz 56002 equivalent).

• Option 5EF: 160 MHz DSP563xx CPU (320 MHz 56002 equivalent).

Option 6: Extended Firmware Algorithm

Option 6 provides an Extended (Pole-Placement) Servo Algorithm firmware instead of the regular servo

algorithm firmware. This is only required in difficult-to-control systems (resonances, backlash, friction,

disturbances, changing dynamics).
