National Instruments PCI-Step-4CX Stepper Motion Controller 

The PCI-Step-4CX is a Closed-Loop Stepper Motion Controller from the ValueMotion Series. The NI PCI-Step-4CX is launched by National Instruments. The NI PCI-Step-4CX is designed for stepper motors with 4 independent axes available. This Closed-Loop Stepper Motion Controller functions with ValueMotion software by NI. The PCI-Step-4CX is fully compatible operating with the following types of software: BridgeVIEW, LabWindows/CVI, and LabVIEW application software. The NI PCI-Step-4CX can be installed on Windows operating systems.

The NI PCI-Step-4CX is designed to work with computers with a Peripheral Component Interconnect (PCI) bus slot. The PCI-Step-4CX is manufactured for stepper motors that are operated in closed-loop mode. This Stepper Motion Controller can operate in open-loop mode as well. The PCI-Step-4CX is available with additional I/O for various functions. The National Instruments PCI-Step-4CX provides a controlling function for home-based switches and can be utilized for other general-purpose functions. The PCI-Step-4CX has a maximum step frequency of 750 thousand steps/s.

The NI PCI-Step-4CX can control position and velocity modes in position or velocity control types of applications. The PCI-Step-4CX utilizes a quadrature encoder for getting position or velocity feedback. The NI PCI-Step-4CX works for defining the direction of stepper motors either in clockwise or counterclockwise modes. The NI PCI-Step-4CX uses an encoding frequency of 1 MHz. The I/O voltage range of this Closed-Loop Stepper Motion Controller is 0 to 5 V.

PCI-Step-4CX Obsolete Status has been announced by National Instruments, but the controller will still be available for purchase and repairs by Apex Waves.
