Control Techniques Overview
Control Techniques Solutions Software are programmes that have been developed to solve a range of common industrial drive applications, they embed years of knoweldge and make full use of our high-performance drive option modules. The following Solutions Packages are available:
Winder (Coiler)
Sectional Control for web conveying
Flying Shear
Duty Assist
Solutions software offers users major benefits:
Total solution saving you a significant amount of development time and cost
Professionally written and tested and then proven in the field, minimising the risk of commissioning delays and subsequent problems
Feature rich, providing flexibility to address the widest range of applications
Fully documented, engineers with a good understanding of the application are able to commission the machine
SM-Application and MD29 option modules fit within the drive footprint and so require no additional panel space or power supplies
Optimum performance, application software is able to access all drive parameters and control loops are synchronised with the drives speed and current loops

Control Techniques Winder solution
The Winder Application Sofware is the result of over 40 years of programing successful winder applicaications for a wide variety of materials and industries. The winder software was initially developed in 2002, since then it has been used in hundreds of processes and has undergone several developments to further enhance the flexibility and performance.
The winder software provides a low cost, high performance solution for a wide variety of winding applications.

Control Techniques Flying Shear
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 maximised.
Typical applications include various types of cut to length machines, depositors, punches, product inspection, or any other process where synchronisation 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 Duty Assist
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, StarDelta, 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 terminal I/O or via fieldbus
Standalone or system configurable
Set-points and feedback can be derived as direct analog signals or by fieldbus
More Features
Auto-changeover to ensure starters are not continually running for long periods of time
Assists number of starts per hour protection (selectable)
Assist Override delay to react to peak demands (selectable)
All data entry for set-up in engineering units
