PCI Motion Control Interface

A client had built a PC-based motion control system. The
system requirements were more stringent than what standard
PC digital and analog I/O boards could deliver, and they
wanted a custom board. The client chose Bolton Engineering
to design the board. |

System
Overview
 Bolton Engineering Inc constructed the PCI Motion
Control Interface using an inexpensive standard PCI
controller chip, plus a custom programmed Programmable
Logic Device (PLD). The PLD implemented eight quadrature
encoder interfaces, control logic for eight bipolar
14-bit Digital to Analog (D/A) converters, cable drive
amplifiers, and a watchdog. A variety of other simple
I/O was included for future expansion. The board
included EMI and ESD protection, as required by FCC part
15 and IEC 61000 standards. To keep costs low, the board
was designed to fit on a half-size PCI card, with only
four fabrication layers.
Project Scope
Bolton Engineering wrote the specification, designed the
schematics, obtained vendor quotes, designed the 4-layer
circuit board, wrote diagnostic and driver software in
‘C’, debugged the system, and delivered five working
prototypes.
