Control Techniques unveils new large frame drive series
Control Techniques, a Nidec brand, is launching a new frame size 12 drive, the largest drive in its 48 year history, a logical progression for Control Techniques (its previous largest drive was frame size 11, operating up to 250kW)– but with more flexible and user friendly than anything else of its kind.
Installation and servicing
For many drive users, designing and building a high-power drive cubicle requires extensive in-house engineering expertise. Enter the frame size 12 drive, which can be fitted with Control Techniques’ celebrated Unidrive M70X or its Powerdrive F300 control module and can be installed into an industry standard cubicle which accommodates both module and accessories. Alternatively, the frame is available pre-assembled in its own industry-standard cabinet, as part of the DFS Series.
It has been engineered to be the lightest high-powered drive of its kind; and one which has pre-engineered accessories to allow replacement by a single engineer in under 30 minutes. And because the drive is smaller than any of its equivalents currently in use, every time it replaces an existing drive it will fit in the space available. During servicing, factory-tested sub-assemblies can be exchanged on site without returning the complete drive to base.
The wider front face design and lower centre of gravity provide greater physical stability and safety during installation, so an installer can handle the wiring and connection singlehandedly using fixed lifting points on the chassis and the comprehensive range of accessories supplied.
Controls, communication and configuration
Frame size 12 is an extension of Control Techniques’ prestigious Unidrive series of AC Drives, targeting fans, pumps, compressors and extruder applications, which makes it ideal for use in processes such as water plants, handling systems and steel manufacture.
All leading industrial communications protocols are supported as standard or with user-fitted option modules. The modules have direct, high-speed access to all drive parameters. In addition, for high performance servo networks such as EtherCAT and CANopen, the drive control loops are synchronized with the communication system to eliminate delays and enhance performance.
Electronic drive optimization
Severe harmonic distortion can cause sensitive electronic equipment such as AC drives to malfunction. Frame size 12 has two rectifiers as standard enabling a 12-pulse supply connection that greatly reduces the most harmful harmonic currents.
Frame 12 also uses the latest microprocessor technology and Insulated Gate Bipolar Transistors (IGBT) technology to reduce EMC/RFI emissions and allow for longer motor leads. Innovative techniques enable IGBTs to shut down rapidly when external faults are detected.
