Introduction 1
1 Introduction
The PCI-8144 is a cost-effective 4-axis motion controller card with
a PCI interface that can generate a pulse train up to 2.4MHz to
control a stepper motor. As a motion controller, it provides non-
symmetric acceleration and deceleration speed profile settings, T-
curve and S-surve speed profile control, and simultaneously start/
stop. Changing speed on the fly is also available with a single axis
operation.
Multiple PCI-8144 cards can be installed in one system. The on-
board switch can be used to the set a specific index for each board
in order to manage multiple cards.
Figure 1 shows the functional block diagram of the PCI-8144 card.
All functions and computations are performed internally by the
ASIC, thus limiting the impact on the PC’s CPU.
