PLEASE NOTE: Effective 2019, we no longer supply Control Techniques variable frequency drives and components. We have drives from several other manufacturers which can meet or exceed the performance characteristics of the Control Techniques line. Simply complete the form below, or contact us with the model of your current or obsolete Control Techniques drive and we’ll be glad to identify a suitable replacement.

Also, the Fincor and Saftronics lines of AC variable frequency drives, DC variable speed drives, and reduced voltage starters were once owned by Emerson but have been obsolete for several years. However, we have many years’ experience working with these drives and can quickly identify replacements capable of exceeding the quality and performance of these older drive technologies. For a suitable replacement, fill out the form below or contact us with your drive or application requirements, and we’ll handle it from there!

Driving Technology Update – January 6 , 2009

SM Module update: SM-Applications Plus / SM-Applications-Lite V2Control Techniques Unidrive SP Application / Programming Module, SM-Applications / SM-Applications-Lite V2.

Now is the time to take advantage of the latest co-processor modules available from Control Techniques for the Unidrive SP. These new modules are replacements for the popular SM-Applications modules and boast twice the processing speed of their predecessors, while retaining all of the same programming features, hardware compatibility, and price.

The SM Applications Plus module replaces the SM-Applications module. The replacement for the SM-Applications Lite module is the new SM-Applications Lite V2 module.

While the original versions will continue to be available for the near future we suggest taking advantage of the new processing power forthwith. Existing programs can be re-compiled and downloaded to the new modules without need for modification.

For use with existing systems, the Undrive SP firmware must be at 1.12.00 or later and the SyPT Pro programming software must be 2.2.0 or later.

Contact your Control Techniques Applications Engineer with any questions.

Application / Programming Modules


Control Techniques Unidrive SP Application / Programming Module, SM-Applications.The SM-Applications module transforms your Unidrive SP drive into a powerful automation controller that adds PLC functionality and can connect to devices via our drive-to-drive network CTNet. This gives you all of the benefits of a fully distributed control system including better performance, reduced cost and smaller electrical panel sizes. Performance – The SM-Applications module contains it’s own high performance microprocessor, leaving the drives own processor to give you the best possible motor performance. It contains 384K of user program memory, meaning that you are never likely to be limited by the program size or processing power of the module. Easy Powerful Configuration – The PLC functionality is programmed using SyPTPro (System Programming Tool) allowing you to tackle automation problems from simple start and stop sequencing to more complex machine and motion control applications. The device is programmed within an IEC61131-3 enviornment with your choice of 3 languages; Ladder Logic, Function Blocks, and text based programming. SyPTPro provides a suite of diagnostic and debugging features for maintenance and to help you to get your solution into service faster. Real Time Control – SM-Applications module gives you real-time access to all of the drives parameters plus access to data from I/O or other drives. The module uses a high-speed multi-tasking operating system with task update times as low as 250µs. Tasks are fully synchronized to the drives own control loop to give you the best possible performance for drive control and motion. Inputs/Outputs – The module has two digital inputs and two digital outputs for high-speed I/O operations such as position capture or actuator firing. The module also features an optically isolated RS485 port, supporting standard protocols such as; Modbus for connection to external devices like Operator Interface panels, or CTSync which is a protocol used for synchronous communication between drives.


Control Techniques Unidrive SP Application / Programming Module, SM-Applications Lite.The SM-Applications Lite module is designed to solve your automation requirements where intelligence is needed on a standalone drive or a drive connected to a centralized controller via I/O or Fieldbus. The Module provides many of the same functions of SM-Applications but may be programmed using either SyPTLite or SyPTPro. SM-Applications Lite with SyPTLite gives you an intermediate level automation solution that is suitable for a wide variety of applications, while SyPTPro and SM-Applications Lite will allow you to exploit the full power and performance of the option module in ‘stand-alone’ applications.


Control Techniques Unidrive SP Application / Programming Module, SM-EZMotion.The SM-EZMotion is ideal for all of your motion control applications whether simple or highly complex. Windows based PowerTools Pro configuration software helps to simplify applications while maintaining flexibility and functionality. The module is equipped with four high speed digital inputs and two digital outputs for external control. Simplify all of your motion applications by using the built-in High-Speed Capture, Queuing, Profile Summation, and Program Multi-tasking capabilities. Ease of use defines this multipurpose motion controller. Take advantage of all its features to quickly solve these applications:

  • Simple Indexing
  • Pick and Place
  • Flying Shear
  • High Speed Labeling
  • Phase Synchronization
  • Random Infeed Control
  • Rotary Knife
  • And many more…

See the Motion Control section of this catalog for more detail on PowerTools Pro Software, which features Motion Made EasyTM programming with Drag and Drop, Point and Click, and Fill in the Blank.
