Frekvensomriktare 890SD 30kW/59A 500V Stl D

The AC890 is a compact and flexible variable speed AC drive that provides high performance and is specifically designed for system integration, saving time and money. This modular system is designed to control speed, torque and position for open and closed loop, single or multi-motor AC induction or PMAC applications. 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 communication and I/O modules to be easily added as needed. DC or AC-fed versions allow design flexibility, and conformal coating is available for most build sizes. AC890 drives are available in 380-460/500 V 3-phase 0.55 to 355 kW and 220 V-240 V 3-phase 0.55 to 7.5 kW.

Features/Benefits:
- Open communication to protect investments:
The AC890 has been intentionally designed to integrate seamlessly into your automation network.
To connect to your PLC or fieldbus network, you can easily choose from the wide range of communication technology options.
- Ultra-fast control loops
- Torque loop: 62.5 µs / - Velocity loop: 62.5 µs / - Position loop: 62.5 µs
- Can handle the most demanding applications:
By utilising advanced control algorithms running on a fast 150 MHz microprocessor, the AC890 drive can achieve very high bandwidth control loops. This allows you to use the drive for the most demanding industrial applications, such as printing, cutting, rotary cutting, converting and slitting.
- Minimal delay between the fieldbus setpoints and the control loops:
Designed to integrate into existing automation systems, the AC890 has high-performance ports that are directly connected to the drive's high-speed control loops. Minimal delay exists between your digital setpoint sent via a fieldbus and the control loops.
Built-in peer-to-peer communication:
- Cascading of setpoints, feedbacks and control signals from inverter to inverter using IEEE1394 or Can communication from inverter to inverter, configured with the powerful and easy-to-use project-based programming software DSE890
- Replacement of analogue solutions:
Your existing analogue setpoint-based solutions can be replaced with a digital fieldbus-based solution with minimal bandwidth loss.
- Flexible feedback:
The AC890 offers system designers complete flexibility in the choice of feedback technology.
- Incremental encoder / - EnDat 2.1 (SinCos) encoder / - Resolver

The AC890 drives can be configured for four different operating modes:
- Open loop (volt/frequency) control
This mode is ideal for basic speed control of one or more motors.
- Sensorless vector control
With its ultra-high performance sensorless vector algorithm, the AC890 delivers a combination of both high torque and close speed control without the need for a speed measurement device.
- Closed-loop vector control
Full closed loop performance for flow vectors can be achieved with the AC890 by simply adding an optional encoder feedback board. This provides 100 % of continuous torque at full load, plus a highly dynamic speed loop that is more than adequate for the most demanding applications.
- 4 Quadrant active front-end power supply module
With this configuration, the energy is fed back to the grid with sinusoidal currents and unity power factor; a very low current harmonic content is achieved (THD < 5 %).

Areas of use:
- Extrusion
- Rolling mills
- Metal treatment
- Pavement lines
- Moulding rolls
