NX1F4_ & NX1F2_ NEXUS Networked I/O Motion Controller

The AMCI Multi-Axis Stepper Motor Controller is a member of our distributed specialty I/O NEXUS product family.

This networked stepper motor controller is available as either a two or four axis controller and can accurately control velocity and position of up to four stepper motors simultaneously. Incremental encoder and discrete inputs can be used to provide additional feedback information for your Stepper Motor application. Its network interface makes it simple to connect this multi-axis stepper controller to a wide variety of PLC's and manufacturing networks.

Designed to operate with AMCI's complete line of stepper drives, the Nexus Multi-Axis Stepper Motor Controller can also operate with drives from many other manufacturers.

PLC-Based Specialty I/O Solutions

Functionally, the AMCI NEXUS controllers and interfaces deliver the same level of PLC integration as their plug-in module counterparts, but with much more flexibility from a systems standpoint. Rather than limit these versatile products to one PLC brand or specific backplane, all units are Din-rail mountable and equipped with a network interface that allows connection to various controllers. AMCI NEXUS specialty I/O integrate with ANY network enabled PLC using Ethernet I/P, Modbus TCP/IP, Profinet, Profibus, ControlNet, or DeviceNet.

The flexibility of a NEXUS controls solution saves time and money, letting customers choose whatever PLC best meets their needs, or change PLCs without having to re-specify and repurchase plug-in modules. And because the NEXUS integrates via network communication, PLC platforms no longer restrict compatibility and integration.
