1 Introduction
The cPCI-8168 is an advanced 8-axis motion controller card with a
6U Compact PCI interface. It can generate high frequency pulses
(6.55MHz) to drive stepper or servomotors. As a motion controller,
it can provide 8-axis linear and circular interpolation and continu-
ous interpolation for continuous velocity. Also, changing position/
speed on the fly is available with a single axis operation.
Multiple cPCI-8168 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 transmis-
sions. cPCI-8168 features the postion compare and trigger output
function which allows users to coordinate the comparing points
with ADLINK library and send the triggering pulse to another
device. In addition, a mechanical sensor interface, servo motor
interface, and general-purposed I/O signals are provided for easy
system integration.
Figure 1-1 shows the functional block diagram of the cPCI-8168
card. The motion control functions include trapezpoidal and S-
curve acceleration/deceleration, linear and circular interpolation
between two axes and continuous motion positioning, and 13
home return modes. All these functions and complex computa-
