MOTION CONTROL: Kollmorgen’s Advanced Kollmorgen DriveTM (AKD) is an Ethernet-based AKDTM that delivers best-in-class performance with industry-leading flexibility, scalability and power range to meet the unique performance requirements of nearly any application; from basic torque and velocity applications, to indexing, to multi-axis programmable motion via the company’s powerful new complete machine automation solution - Kollmorgen Automation SuiteTM. As a result, machine builders are able to standardize on a single drive family with a common Graphical User Interface (GUI) across the power range to deliver optimized machine performance, throughput and accuracy across multiple applications, while minimizing engineering time and costs associated with stocking, understanding and programming multiple types of drives.The AKD is available for 120/240V ac or 480V ac operation, with a power range of 3 to 24 Arms continuous current, 9 to 48 Arms peak. Models with an industry-leading power range up to 96 Arms continuous and 192 Arms peak will be available in 2010. The AKD’s high power density enables machine builders to get more power from a drive as small as 168 x 57 x 153 mm. As a result, OEMs can reduce the size of their machine, or increase its power without increasing its size. And with common interface and hardware across the entire AKD power range, machine builders will benefit from faster commissioning and troubleshooting, too.
The AKD is uniquely capable of supporting a variety of feedback devices and Ethernet Motion buses from the base hardware, without the need for any separate option cards. Currently supported feedback devices include Smart Feedback Devices (SFD), Endat, BiSS, Analog Sine/Cos encoders, incremental encoders, HIPERFACE® and resolvers. Currently supported Ethernet Motion buses include EtherCAT®, CANopen® and Modbus/TCP. Because these capabilities are available “out of the box” from the base hardware, the AKD maximizes quality and operational flexibility while reducing costs and overall footprint increases associated with integrating option cards.
The AKD delivers patented Autotuning algorithms that automatically adjust all gains, including patent-pending observers. This advanced Autotuning functionality also provides immediate and adaptive responses to dynamic loads and promises precise control of all motor types. Additionally, Autotuning can help overcome less-than-perfect mechanical designs and help machine builders solve even the most challenging scenarios by compensating for compliant transmissions and couplings that would otherwise rob a machine of its intended performance.
With up to 27-bit resolution, the AKD delivers the industry’s lowest noise characteristics for improved machine precision. Additionally, a powerful dual processor system executes industry-leading servo algorithms with high resolution for very fast settling times. Because the AKD provides torque loop updates in 0.67 μs, while velocity and position loops lead the market at 62.5 μs and 125 μs, respectively, these drives immediately accommodate changing load conditions for industry leading performance.
The AKD’s easy-to-use GUI features a six-channel real-time software oscilloscope for fast commissioning and diagnosis. A multi-function Bode plot allows users to quickly evaluate performance, while Auto-complete functionality of programmable commands saves looking up parameter names. One-click capture and sharing of program plots and parameter settings allow users to send machine performance data instantly.
Additional features and benefits include:
- Digital signal processor control supports reliable, repeatable steps
- Screw terminal connectors on I/O allow for fast and easy installation
- Optically-isolated I/O reduces noise, and eliminates need for additional hardware
- SIL-qualified, over-voltage, current, and temperature detection for added dependability
- Option cards that increase available I/O and add NVRAM
- Processing power providing multi-axis machine control capability
The AKD is rated for operation in ambient temperatures ranging from 0 to 40C (up to 55C with de-rating), and boast a robust MTBF of nearly 660,000 hours. They conform to Category 3/Sil2 and RoHS standards, meet the insulation requirements of IEC60601, are UL listed and carry the CE mark.
The breadth and depth of features delivered by the AKD make it an ideal high performance drive solution in a wide range of applications in any number of industries, including packaging, converting, printing, food and beverage, material forming, solar and medical.
