Introduction

Advantech introduces the PCI-1240U 4-axis Universal PCI (supports both 3.3V and 5V signal slot) stepping/pulse-type servo motor control card designed for general-purpose

extreme motion applications. The PCI-1240U is a high-speed 4-axis motion control card for the PCI bus that simplifies stepping and pulse-type servo motor control, giving you

added performance from your motors. The card’s intelligent NOVA

MCX314-motion ASIC builds in a variety of motion control functions, such as 2/3-axis linear interpolation, 2-

axis circular interpolation, T/S-curve acceleration/deceleration rate and more. In addition, the PCI-1240U performs these motion control functions without processor loading during

driving. For advanced applications, Advantech supplies Windows

DLL drivers and user-friendly examples to decrease your programming load. Moreover, through a free bundled

PCI-1240U motion utility, you can complete configuration and diagnosis easily.
