Introduction
The PCI-8134/PCI-8134A is a 4-axis motion control card with PCI interface. It
can generate high frequency pulses to drive stepping motors and servo
motors. Multiple PCI-8134/PCI-8134A 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/PCI-8134A card.
PCI-8134/PCI-8134A uses motion ASIC to perform 4-axis motion control.
These ASICs are incorporate Nippon Pulse Motor. 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 application included with the PCI-
8134/PCI-8134A card for supporting application development. 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/PCI-8134A 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.
The following flowcharts show recommending processes for using this manual
to develop an application. Please also refer to the relative chapters for details
of each step.
