Kollmorgen introduces the Advanced Kollmorgen Drive (AKD). The Ethernet-based AKD delivers performance with flexibility, scalability and power range to meet the performance requirements of nearly any application, from basic torque and velocity applications to indexing and multi-axis programmable motion via the company’s complete machine automation solution — Kollmorgen Automation Suite. 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 120/240 VAC or 480 VAC operation, with a power range of three to 24 Arms continuous current, nine to 48 Arms peak. The AKD’s high power density enables machine builders to get more power from a drive as small as 168 millimeters by 57 millimeters by 153 millimeters. 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.

The AKD is 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.

The AKD delivers Autotuning algorithms that automatically adjust all gains, including 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 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 low noise characteristics for improved machine precision. Additionally, a dual processor system executes servo algorithms with high resolution for fast settling times. Because the AKD provides torque loop updates in 0.67 μs, with velocity and position loops at 62.5 μs and 125 μs, respectively, these drives immediately accommodate changing load conditions for improved performance.

The AKD’s 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 of note 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°C to 40°C (up to 55°C with de-rating), and boasts an MTBF of nearly 660,000 hours. It conforms to Category 3/Sil2 and RoHS standards, meets the insulation requirements of IEC60601, is UL listed and carries the CE mark.
