PCI-8504/ 8504L
Introduction
The PCI-8504 is a PCI-bused, four-axis motion
control board. It’s designed to control both servo and
stepper motor. The PCI-8504 thus has two modes:
The first one is to work with an analog interfaced,
velocity mode servo drive. The PCI-8504 compares
the segmental movement commands from Host PC
and encoder feedback from servo motor, close the
position loop once every 250ns and send the analog
output velocity command to the velocity mode servo
drive. The second mode is to convert the segmental
movement command into well behaved pulse trains to
either a position mode servo or a stepper drive. In
addition to a Windows kernel soft driver, we also
support the RTX (VenturCom) driver for applications
requiring higher level of hard real time.
Higher Level of Hard Real Time Control:
RTX Driver
Depending on the level of CPU in your system,
normally the “Block Processing Time” of a RTX
motion application in Windows XP/2000 with the
PCI-8504 can easily reach to a 500us level
deterministically in a Pentium IV system while the
CPU still has abundant power to perform Soft Logic
and HMI.
