Video: New large frame drive series delivers 500 kW of power

28 October 2020

Control Techniques has launched is biggest-ever drive – a 500 kW frame 12 design claimed as the lightest high-powered drive of its kind. The unit can be installed by a single engineer in less than 30 minutes using pre-engineered accessories.

For many drive users, designing and building a high-power drive cubicle requires extensive in-house engineering expertise. Enter the 500 kW High Power Drive, which can be fitted with Control Techniques’ 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-Source: Control TechniquesSource: Control Techniquesassembled in its own industry-standard cabinet, as part of the DFS Series.

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 center 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.

The 500 kW High Power Drive is an extension of Control Techniques’ 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.

Severe harmonic distortion can cause sensitive electronic equipment such as AC drives to malfunction. 500 kW High Power Drive has two rectifiers as standard enabling a 12-pulse supply connection that greatly reduces the most harmful harmonic currents. The new drive also uses the latest microprocessor technology and insulated gate bipolar transistor (IGBT) technology to reduce electromagnetic/radiofrequency interference emissions and allow for longer motor leads.
