Turbo PMAC PCI Lite
Introduction 1
INTRODUCTION
The Turbo PMAC PCI Lite is a member of the Turbo PMAC family of boards optimized for interface to
traditional servo drives with single analog inputs representing velocity or torque commands. Its software
is capable of 32 axes of control. It can have up to four channels of on-board axis interface circuitry. It
can also support up to 32 channels of off-board axis interface circuitry through its expansion port,
connected to Acc-24P or Acc-24P2 boards.
The Turbo PMAC PCI Lite is a full-sized PCI-bus expansion card. While the Turbo PMAC PCI Lite is
capable of PCI bus communications, with or without the optional dual-ported RAM, it does not need to be
inserted into a PCI expansion slot. Communications can be done through an RS-232 or RS-422 serial
port. Standalone operation is possible.
ICs U140, U143, and U147 are
installed in the Turbo version of the
PMAC Lite PCI board.
The same circuit board with some ICs not installed produces a (non-Turbo) PMAC PCI Lite controller.
The above diagram shows the key components installed in the Turbo configuration only.
Board Configuration
Base Version
The base version of the Turbo PMAC PCI Lite provides a 1-1/2-slot board with:
80 MHz DSP56303 CPU (120 MHz PMAC equivalent)
128k x 24 SRAM compiled/assembled program memory (5C0)
128k x 24 SRAM user data memory (5C0)
1M x 8 flash memory for user backup & firmware (5C0)
Latest released firmware version
RS-232/422 serial interface, 33 MHz PCI (PC) bus interface
Four channels axis interface circuitry, each including:
16-bit +/-10V analog output
3-channel differential/single-ended encoder input
Four input flags, two output flags
Interface to external 16-bit serial ADC
Display, control panel, muxed I/O, direct I/O interface ports
PID/notch/feedforward servo algorithms
Extended "pole-placement" servo algorithms
1-year warranty from date of shipment
One manual per set of one to four PMACs in shipment
(Cables, mounting plates, mating connectors not included)
Option 2: Dual-Ported RAM
Dual-ported RAM provides a very high-speed communications path for bus communications with the
host computer through a bank of shared memory. DPRAM is advised if more than 100 data items per
second are to be passed between the controller and the host computer in either direction.
Option 2 provides an 8k x 16 bank of dual-ported RAM in component. The key component on the
board is U1.
