Controller/driver only (without motors). Normally you will purchase the integrated motor/controller.<p>This unit is the same as described for the integrated motor/controllers pages, but usually comes with a 5 pin connector. Select this controller to drive unipolar stepper motors that are size 23 (57mm) or smaller. The 10A-USB can drive up to 10 amps burst, 3 normally. These controllers are microminiature and exceptionally small, see the motor/controller drawings for dimensions. Select this controller for the most economical solution. Serial USART is +5 volt USB with mini-USB female connector. You will need a standard mini-USB--female type-A cable, see our cable on the Accessories page.

Our controllers run "right out of the box" by typing a 'w' then 'G'. Each Excitron controller includes all the electronics and drivers for running the stepper motor. There are no separate electronic boxes and no messy cables. Included here is a full range of details of our motor/controller family.

You easily control how your stepper motor operates in these modes:

• Serial Command Mode: send and receive via RS232, TTL (+5v logic), or USB are either optional or built-in. Connection with PCs, PLCs or Labview work well.
• Standalone Motion Profile Mode: repeatedly run a sequence of motion profiles, exactly as you wish, upon powerup. In this case, your computer is not needed. You can use inputs to control how and when these profiles run.
• Input Profile Mode: each of up to 5 input pins trigger 3 motion profiles each, giving you random selection of motion by simply pushing buttons.
• Manual Onboard switches: each built-in switch runs 1 or 2 motion profiles.
• Driver (CNC step/dir) Mode: motor steps each time when an external STEP occurs, in the direction set by DIRECTION. CNC programs usually output these signals on a PC parallel port.
• Encoder: encoder and/or Index input signals can be counted by the Controller, and you can enable or disable various encoder functions such as stopping if a blockage occurs.

You can combine many of these modes, with few restrictions. Hundreds of successful customers have created very ingenious motion using these simple "building blocks", some in as little as 10 minutes.

You can easily setup the Excitron controller for standalone (Motion Profile) mode so that it performs exactly as you wish upon powerup. In this case, your computer is not needed. The Excitron controller has many useful modes for inputs and for the one output, so that you can add intelligent repetitive motion to almost any device. Connection with PLCs or Labview work well.
