Parker AC890 Inverter Drives
Parker AC890 VFD (Variable Frequency Drive) Series
The AC890 are a compact, modular system variable speed AC drive engineered to control speed and position of open-loop and closed-loop, single or multi-motor AC induction or servo motor applications. Compatible with a wide range of feedback options, the AC890 variable speed drive is compatible with any AC motor and virtually any speed/position feedback options. With this flexibility you may not even need to replace your existing AC motor to achieve high performance, saving you time and money. The AC890 drives are available in 380-460/500V 3-phase 0.55 to 1200kW and 220V-240V 3-phase 0.55 to 7.5kW.
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 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.
- 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%).
