Introduction
The PCI-8134 is a 4 axes motion control card with PCI interface. It can
generate high frequency pulses to drive stepping motors and servo motors.
Multiple PCI-8134 cards can be used in one system. Incremental encoder
interface on all four axes provide the ability to correct for positioning errors
generated by inaccurate mechanical transmissions. In addition, mechanical
sensor interface, servo motor interface and general purpose I/O signals are
provided for system integration.
Figure 1.1 shows the function block diagram of PCI-8134 card. PCI-8134
uses two ASICs (PCL5023) to perform 4 axes motion control. These ASICs
are made of Nippon Pulse Motor incooperation. The motion control
functions include linear and S-curve acceleration/deceleration, interpolation
between two axes, continuous motion, in positioning and home return are
done by the ASIC. Since these functions needing complex computations
are done internally on the ASIC, the PC’s CPU is free to supervise and
perform other tasks.
Motion Creator, a Microsoft Windows based software is equipped with the
PCI-8134 card for supporting application development. The Motion Creator
is very helpful for debugging a motion control system during the design
phase of a project. The on-screen monitor shows all installed axis
information and I/O signals status of PCI-8134 cards. In addition to Motion
Creator, both DOS and Windows version function library are included for
programmers using C++ and Visual Basic language. Several sample
programs are given to illustrate how to use the function library.
Figure 1.2 is a flowchart that shows a recommending process of using this
manual to develop an application. Please also refer the relative chapters
for the detail of each step.
