The AC890 is a compact, modular systems drive engineered to control speed and position of open-loop and closed-loop, single- or multi-motor AC or servo motor
Parker 890 Applications:
Features
The AC890 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 any speed measuring transducer.
Closed-loop vector control
Full closed-loop flux vector performance can be achieved with the AC890 by simply adding an encoder feedback‘technology box’. This provides 100% continuous full load standstill torque, plus a highly dynamic speed loop more than sufficient for the most demanding applications.
Demanding environments
For environments that have dusty, humid or corrosive atmospheres, the AC890 can optionally be supplied with conformally coated circuit boards that improve the drives
resistance to corrosion, thereby increasing reliability and service life.Industries that would typically benefit from conformal coating could include :
- Water and wastewater
- Paper and pulp processing
- Steel
- Marine and offshore
- Outdoor cranes
- Wind & wave power generation
- Food processing.
