The National Instruments PCI-7390 is an advanced P-Command (Position Command) type stepper motion controller, part number 779034-01 and 192689B-01L. Designed for reliable performance, this controller enables motion control for up to four coordinated or independent axes. It supports both P-command mode devices and those compatible with step command input, ensuring flexible integration into a variety of automation systems. The PCI-7390 features specialized connectivity to popular servo drive manufacturers including Panasonic Minas, Mitsubishi MR-J2S, Yaskawa, and Sigma II through dedicated accessories.

Incorporated within its design is a 100-pin SCSI I/O connector that facilitates comprehensive motion I/O functionality, enabling inputs and outputs for limit switches, encoders, and general-purpose signals. The device supports trajectory update rates ranging from 62.5 µs to 500 µs per sample, with a velocity range spanning 1 to 4,000,000 steps per second and a maximum step frequency of 4 MHz. The PCI-7390 requires a +24 V external power supply to power its optical isolation circuitry, and configuration of the motion I/O is simplified through software, negating the need for manual setup apart from jumper settings for general-purpose output configurations.

The NI PCI-7390 operates using the NI-Motion driver software, compatible with LabVIEW, LabWindows/CVI, or ANSI C. It measures 7.03 x 3.9 inches and weighs 0.29 lbs, with an operating temperature range of 0 °C to 55 °C and a storage temperature range of –20 °C to 70 °C, allowing for robust application in diverse environments. This device comes with a three-year warranty, and although it has been designated as obsolete by National Instruments, it remains available for purchase and repair through Apex Waves.
