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!

Drive Configuration and Programming


This is a standard feature that enables simple configuration of parameters in a variety of ways. The SmartCard can:

  • ‘Clone’ a complete set of parameters for serial production
  • Save multiple complete sets of parameters
  • Set up an application as parameter differences from default
  • Automatically save all user parameter changes for maintenance purposes
  • Load complete motor map parameters
  • Read/write SmartCard information from within SM-Applications and SM-Applications Lite programs.

The drive only communicates with the SmartCard when commanded to read or write, meaning the card may be “hot swapped”.

Control Techniques Unidrive SP Communication Cable.COMMUNICATION CABLE

Using a special RS232 to RS485 converter you can connect the PC to the RJ45 drive. A special pre-made cable is available from Control Techniques for this purpose – this CT Comms Cable is used with other Control Techniques products that use a RJ45/RS485 connector such as the Commander SE and Commander SK. The RJ45 socket is located under a small flap on the front of the Unidrive SP just below the keypad. The pin-out of this connector is described in the Unidrive SP User Guide.
