Introduction
The PPCI7443 is an advanced 4 axes motion controller card with PCI
interface. It can generate high frequency pulses (6.4MHz) to drive
stepping/micro stepping motors and servo motors. In motion functions, it
provides 2-axis circular, 4-axis linear interpolation, continuous interpolation
with velocity continuity. Also, change position/speed on the fly are available
in single axis operation. Multiple PPCI7443 cards can be used in one
system. Incremental encoder interface on all four axes provide the ability to
correct
positioning errors generated by inaccurate mechanical
transmissions, and with the help of on board FIFO, PPCI7443 can also
perform precise and extremely fast position compare and trigger function
without consuming CPU resource. 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 PPCI7443 card. PPCI7443
uses one ASICs (PCL6045) to perform 4 axes motion control. These ASICs
are made of Nippon Pulse Motor incorporation.
The motion control
functions include linear and S-curve acceleration/deceleration, circular
interpolation between two axes, linear interpolation between 2~4 axes,
continuous motion, in positioning and 13 home return modes 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.
PPCI7443 Utility, a Microsoft Windows based software is equipped with the
PPCI7443 card for supporting application development. The PPCI7443
Utility 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 PPCI7443 cards. In addition to
PPCI7443 Utility, both DOS and Windows version function library are
