Parker: AC Drives (AC890 Series) Parker offers a full range of drives including stepper, compact and high performance servo, AC variable speed, high current output DC and panel mounted drives. Parker industry leading drives include Sensorless, Vector and Microstepping options. Parker drives are suitable for speed, torque or position control and are available in power ranges from fractional to over 2,000 hp. Parker also offers inverters for renewable energy applications that convert DC power to AC electricity and deliver power to the grid, allowing hybrid vehicles and mobile equipment that convert regenerated power to battery storage to reduce fuel consumption and emissions.
AC Variable Frequency Drives, HP Rated - AC890 Series
The AC890 is a compact, modular systems AC drive engineered to control speed and position of open-loop and closed-loop, single- or multi-motor AC induction or servo motor applications, up to 1500HP.
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 induction or servo motor applications. Compatible with a wide range of feedback options, the AC890 may be used 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 is available in 380-460/500V 3-phase 0.75 to 1500HP and 220V-240V 3-phase 0.75 to 10HP.
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. 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 < 3%).
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, registration, cut-to-length, rotary shear, converting and slitting. To EN18849 PL-e / SIL3, frame B-F
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.
Replacement of analog solutions:
Your existing analog setpoint-based solutions can be replaced by a digital fieldbus-based solution with minimal bandwidth loss.
The AC890 offers system designers complete flexibility in their choice of feedback technology.
Open standards 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 boxes.
Two performance level options for your needs:
Advanced performance - 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), full function PID, machine state and others. High performance - All advanced features plus: library of pre-engineered application specific LINK VM function blocks such as: shaftless printing, cut-to-length, advanced material winding, advanced traversing and others.
