Reducing installation time and costs are very important to most people.  Parker SSD Drives feels the same, and that is exactly why they are launching an innovative, modular, high-power AC drive system.  The 890PX is easy to install, simply requiring connection to a power supply and downstream induction, torque, or permanent-magnet servo motors, to operate.  Dedicated plug-in drive modules make setup or subsequent reconfiguration quick and simple.  Costs are even further cut through standard pre-engineered hardware.

The rugged 890PX is available in 380-460V and 500-690V configurations, with power ratings of up to 400kW.  This makes it suitable for use in a wide range of demanding applications in different sectors such as the plastics, paper, textile, energy and heavy manufacturing and process sectors.

Each unit is constructed around a set of modules mounted in a robust steel fabricated high-power industrial device.  Unlike many competing systems where ancillary hardware is supplied at extra cost, the industrial device 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.

Apart from the above, each 890PX system is supplied with a series of sealed power drive modules that simply plug-in to the power frame.  The purpose of these modules is to minimize external wiring.  They 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 to a common bus rail within the tower enclosure.  Further modules are available for power input and output, while a separate operator interface panel features an industry-standard keypad, with a USB port enabling programming to be carried out remotely.

The 890PX is compatible with all leading protocols, including Ethernet, ProfiBus, ControlNet, DeviceNet, CanOpen and Firewire, using appropriate card modules.  The 890PX can be supplied for either top or bottom power entry for use in markets around the world.  Each power module has been manufactured to be compact and relatively lightweight.  This enables it to be easily shipped and installed by local technicians.
