AC Drive Parker 890CD-232240C0-000-1A000 5.5KW

The AC890 is a compact and flexible variable speed systems AC drive achieving high performance and designed specifically for systems integration, saving you time and money. This modular system is engineered to control speed, torque and position of open-loop and closed-loop, single or multi-motor AC induction or PMAC motor applications. Compatible with a wide range of feedback options, the AC890 variable speed drive is compatible with any AC induction or PMAC motor and virtually any speed/position feedback option. Three option slots allow a wide range of communications and I/O modules to be easily added as required. DC or AC fed versions enable design flexibility, and conformal coating is available on most frame sizes. AC890 drives are available in 380-460/500V 3-phase 0.55 to 355kW and 220V-240V 3-phase 0.55 to 7.5kW.

Features/Benefits:
• Open communications for protection of investment:
The AC890 has been deliberately designed to integrate seamlessly into your automation network.
To connect to your PLC or fieldbus network you can simply choose from the wide range of communication technology options.
• Ultra-fast control loops –
– Torque loop : 62.5µs / – Speed loop : 62.5µs / – Position loop : 62.5µs
• Serves the most demanding applications:
Taking advantage of leading edge control algorithms running on a fast 150Mhz microprocessor, the AC890 drive can achieve very high-bandwidth control loops. This allows you to use the drive for the most demanding industrial applications e.g. printing, cut-to length, rotary shear, converting and slitting.
• Minimal delay between the fieldbus setpoints and the control loops :
Designed to integrate in existing automation systems, the AC890 features high performance ports linked directly to the fast control loops of the drive. Minimum delay exists between your digital setpoint sent through a fieldbus and the control loops.
Native Peer-Peer communications:
• Cascading of setpoints, feedbacks and control signals from drive to drive using IEEE1394 or Can communications from drive to drive, configured with the powerful and easy to use project based DSE890 programming software
• Replacement of analogue solutions:
Your existing analogue setpoint-based solutions can be replaced by a digital fieldbus-based solution with minimal bandwidth loss.
• Flexible feedback:
The AC890 offers system designers complete flexibility in their choice of feedback technology.
– Incremental encoder / – EnDat 2.1 (SinCos) encoder / – Resolver

The AC890 variable speed drives can be configured for 4 different modes of operation:
• Open-loop (volts / frequency) control
This mode is ideal for basic, single or multi-motor speed control.
• Sensorless vector control
With its ultra high performance sensorless vector algorithm, the AC890 delivers a combination of both high torque and close speed regulation without the need for a  speed measurement device.
• Closed-loop vector control
Full closed-loop flux vector performance can be achieved with the AC890 by simply adding an encoder feedback option card . This provides 100% continuous full load standstill torque, plus a highly dynamic speed loop more than sufficient for the most demanding applications.
• 4 Quadrant active front-end power supply module
With this configuration, the energy is fed back into the mains supply with sinusoidal currents and unity power factor; a very low current harmonic content is achieved (THD < 5%).

Applications:
• Extrusion
• Rolling mills
• Metal finishing
• Coating lines
• Forming rolls
• Fan & pump control
• Paper & pulp processing
• Printing
• Hoists and Winches

Technical Specifications:
One high performance level option for your needs:
Motion control with added position loop, motion control function blocks, move incremental, move absolute, move home, line drive master ramp and section control, winder blocks (speed winder, current winder), multiple full function PIDs, state machine, registration control and much more.
