[edit] Overview

The nC1 Adjustable Speed Drive family are sub-micro, or nano-sized, drives with a very full set of features. They can be powered with either single-phase or three-phase 120Vac - 230Vac. Being able to run on 120V Single phase solves many small OEM applications. The nC1's provide better control for your applications, more protection for your motors and more room in your cabinets.

[edit] Easy To Program

The nC1 uses a simple, straightforward programming menu for quick and easy set-up of the drive. There are no complicated sub menus or “hidden” parameters. By using the built-in programming wizards, the nC1 can be programmed for simple operations with the push of a button. there is Windows programming software available that makes setting up the drive a snap.

[edit] User-Friendly Operation

The nC1 comes ready to run. Simply mount the drive, run your power connections and you are ready for operation. Many operations require no programming whatsoever. The user-friendly interface is designed to set the speed and start/stop functions of the unit easily. The drive will also operate from nearly any standard industrial control inputs.

Array of Communications In today’s fast-paced manufacturing world, coordinated systems require communications from drive-to-drive and drive-to-system. A built-in port and a variety of option cards give you versatility in communication selection. Built-in RS232/RS485 Port
