Please see Gearhead drawing pdf for mechanical dimensions and details.  Other pdfs are in the Documentation link.

Includes precision 0.90 degree per half-step stepper motor with integrated controller, 20 volt 90 watt high efficiency slim encapsulated power supply, 6 foot RS232 DB9 cable, and 9 pin I/O control cable.  Nothing else to add, runs right out of the box.  Click here. for motor/controller drawing and details.

Easily change direction, number of steps, speed, acceleration, torque, time delays, and other motion controls.  Gold plated connectors, gold printed circuit boards, and gold plated covers for ultimate reliability, heat flow, and performance.  Key specifications etched in real 24K gold on top cover.

On-board RS232 serial communication port, selectable baud from 4,800 to 230,400.  Loopback DB9 tester included.  Input/output port has  6 input pins (2 analog), and 1 output pin for external motion control. Use the included I/O cable for easy connections to your switches and speed pot.
 
No software needed to operate once you set-up the controller for various modes, such as Driver CNC Mode, standalone, and/or using external inputs for Input Profile Mode.  You will need a serial port program (see Serial port programs download link) to communicate and setup initially, therafter using the serial port is optional.  After 40 years experience in the technology field of communications, we worked hard to give you a truly easy-to-use yet powerful motion controller.

Starting with firmware version 4.09, your controller operates in all available modes without limitation.  For example, you have set-up for Driver CNC mode, where external pulses step the motor, and you can operate the motor via RS232 serial port commands, and you can manually rotate the motor using external switches.  No other controller in the world gives you this much versatility coupled with such simplicity of operation.
 
Now Includes internal integrated optical encoder, produces postive feedback, saves space, wire, increases reliability, and makes your products superior.

Intelligent microcomputer with enough memory and speed for full automatic and robotic motion control.  Multi-axis capability eliminates PLCs and PCs in some cases.  Contains all the electronics required for complete motor control--nothing else needed.  Full backwards compatibility with previous Excitron Controllers.

See Au_Controllercoder Manual for most details.  Power supply same as our PS20-90W-1, in Power Supply category, and comes pre-wired with the 8 pin Power/RS232 connector and cable.

Package price above is hundreds of dollars less than top selling competitor's motors.  Comparable price from Oriental, Allen-Bradley, which do not even offer absolute encoder nor gearheads, is much higher in cost.

These are new production products, with extra-precision firmware. However, the firmware for the wireless link is not available until 2011.  At that time, fully functional units with wireless link will be available for approximately $100 additional charge.  This future optional 2.4ghz RF offers 6LoPAN and unique internet address for worldwide remote control, diagnostics, updates, and status.

"Con-trol-ler-co-ders"--stepper motor controllers with optical encoders built-in. Each Controllercoder is fully integrated with the stepper motor, producing the most compact and powerful intelligient motor drive available. Complete family can drive stepper motors from 15mm diameter to NEMA 42, and perfectly matches drive amperage with the motor size. The absolute optical encoder and Index give position feedback for optimal motion control. These units offer the first total 100% motor drive solution, allowing easy plug-n-play for machines, CNC, robots, actuators, vehicles, and all equipment.
