Parker SSD Drives, part of the Automation Division of Parker Hannifin, has developed a modular, high power AC drive system to help customers reduce installation time and costs. The 890PX is easy to install, requiring only connection to a power supply and downstream induction, torque or servo motors, to operate. Dedicated plug-in drive modules make setup or subsequent reconfiguration quick and simple, and standard pre-engineered hardware cuts costs still further.
The tower frame of the Parker 890PX incorporates all common components as standard
The rugged 890PX is available in 380-460 V and 500-690 V configurations, with power ratings of up to 730 kW.
Each unit is constructed around a set of modules, mounted in a robust steel fabricated tower frame with a small 500 x 500 mm footprint. Unlike many competing systems where ancillary hardware is supplied at extra cost, the tower frame incorporates all common components such as circuit breakers, fuses, motor cooling blocks, harmonic-reducing input line reactor, dynamic braking with resistor, and cooling and ventilation units as standard.
Each 890PX system is supplied with a series of sealed power drive modules that plug-in to the power frame. These modules are designed to minimise external wiring, are fully configured with inverter phase assemblies, DC supply, capacitors and cooling fans and are fitted with self-aligning silver plated connectors for quick and secure connection. Further modules are available for power input and output, while a separate operator interface panel features an industry standard keypad.
The controller is compatible with leading protocols, including Ethernet, ProfiBus, ControlNet, DeviceNet, CANOpen and Firewire, using appropriate card modules. Power modules are compact and easily installed by local technicians.
The modular nature of the 890PX technology also means that individual units can be linked together quickly and simply, providing an easily upgradeable system, that can be modified and extended as the needs of end users change. Parker SSD Drives also provides a comprehensive range of technical and customer applications services, plus a global network of manufacturing and sales offices for local spares and support.
