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!

Pre-packaged Solutions for Unidrive SP

“Solutions” for the Unidrive SP enable quick startup on some of the most common industrial applications.

Control Techniques Unidrive SP Dual Mode Winder Solutions.

The Dual Mode Winder Application Software is the result of over 35 years of programming successful winder applications for a wide variety of materials and industries. The term” Dual Mode” refers to the ability of the software to switch between torque and speed control modes, often a critical requirement in demanding applications such as high speed dual-turret, flying splice machines. The Dual Mode Winder Application Software supports over 95% of industrial winding applications. The addition of an SM module loaded with the Dual Mode Winder software provides a low cost flexible solution for a wide variety of winding applications.

Control Techniques Unidrive SP Flying Shear Control Solutions.

The Flying Shear is a common industrial application for cutting a continuous product to a set length while at line speed. This means that the main production process is not interrupted, and so machine productivity is maximized.

Typical applications include various types of cut to length machines, depositors, punches, product inspection, or any other process where synchronization at line speed is required.

Standard Features

  • Easy configuration
  • Hardware and software limits
  • Manual jog functions
  • Several homing modes
  • High speed output is used to initiate the cut
  • Registration capture
  • Batch control functions
  • Dynamic motion profile changes on the fly
  • Engineering units are used for programming
  • Units are defined for the master and slave axis as the number of encoder counts per unit. These are entered as a numerator and denominator to allow fractional values
  • Resolution of the ‘cut-length’ may be entered to within 0,001 units
  • Profile optimization reduces the machines mechanical stress: The return profile is calculated to operate at the slowest speed and acceleration rate, and yet with sufficient time to achieve the next cut, either triangular or trapezoidal profiles are used
  • Parallel and angled carriage applications are handled

Control Techniques Unidrive SP Fan and Pump Duty Assist Solutions.

The Duty-Assist control is an effective method of controlling multiple pumps or fans in parallel to maintain the required process demand. Pumps and fans are often used in parallel banks to avoid motor overload, guarantee security of supply through system redundancy, reduce running costs due to system load cycles, and provide a wide range of control and flexibility.

The system consists of a ‘Duty’ Drive and assist starters. The assist starters can be of any type, (e.g, Contactor, Wye-Delta, Auto-Transformer, Soft Starter or Inverter); the choice is dependent on the system limits. The Duty drive can control one dedicated motor (Fixed Duty), or with additional external switchgear could be selected to control other motors within the parallel configuration (Flexible Duty).

Standard Features

  • Fixed Duty Motor – up to 4 assist starters can be controlled
  • Flexible Duty Selection – up to 3 assist starters can be controlled
  • Assist or Duty selection by Runtime (to ensure each pump/fan is equal used) or a set sequence
  • Automatic reselection requested assist fails to start
  • Local/Remote: Digital control from Unidrive SP terminal I/O or via fieldbus
  • Stand-alone or system configurable
  • Set-points and feedback can be derived as direct analog signals or by fieldbus
  • 2 selectable process set points for use with day/night function
  • Process High and Low trip thresholds (selectable)
  • Inverse Speed characteristic (selectable)
