CTC releases EtherCAT Master for 5300 Controller


HOPKINTON, MA, June 4, 2013  – Control Technology Corp., a leading manufacturer of automation controllers that integrate motion control, I/O, user interfaces, and enterprise connectivity, has released its EtherCAT Master for the model 5300 controller.  


EtherCAT is supported in the CTC model 5300 series of control systems in the form of an EtherCAT Master module (model M3-41A), offering high-performance control of networked servos, stepping motors and I/O devices. This Master module can coexist in the same system with Modbus®, DeviceNet® and BACnet® interfaces, allowing for multi-vendor configurations with the CTC system acting as a protocol bridge as well as a control system.


Unlike other implementations, CTC has fully integrated EtherCAT into its programming environment, QuickBuilder, by pre-engineering support for the most popular EtherCAT slave devices. Through auto-discovery, the system automatically determines what specific devices are on the EtherCAT network and automatically configures the master to talk to them. This eliminates the time-consuming and potentially error-prone step of having to use a configurator to manually set up the network.  


EtherCAT-based drives and I/O points appear in the programming environment along with any other drives and I/O on the system, and are programmed as though they were local devices. This means users can freely and transparently intermix local and remote servos and I/O, or change a device from local to remote without extensive programming changes.  
The EtherCAT Master is programmed with CTC’s QuickBuilder programming environment, which includes high-level motion controls as part of its basic structure. Commands for segmented, geared/cammed, position, and velocity moves are pre-programmed in QuickBuilder with Motion Sequence Blocks (MSBs). Multi-master and virtual master are supported, and Quickbuilder also includes an interactive motion control debugger with a built-in status/error data logger utility.
Basic features and motion modes include:
  • Cyclic Sync Position
  • Interpolated Position
  • Profile Velocity
  • Profile Position
  • Any motor can track / gear / cam off any other motor
  • Distributed Clock by default
    • syncs master to slaves
    • provides simultaneous motions
  • 1 mS control loop for all axes

CTC prides itself on providing users with a broad selection of technologies available for its basic control platforms, so that OEMs, control systems integrators, and end users can develop systems that are optimized for their specific projects. “We designed our EtherCAT implementation to provide all the benefits that EtherCAT has to offer with the advantage of autodiscovery and autoconfiguration to make this powerful technology easy to use,” said CTC CEO Tom Schermerhorn.

The devices currently supported include:
  • Yaskawa Sigma 5
  • Copley Accelnet
  • Kollmorgen AKD 
  • Sanyo Denki 
  • Control Techniques (Emerson)
  • Beckhoff I/O
  • Wago I/O
  • SMC Valve Stacks and I/O
Additional devices will be added as needed or requested by customers.

Kollmorgen AKD™ EtherCAT® Servo Drives

Radford, Va, May 10, 2010 – Ethernet-based AKD™ Servo Drivesfrom Kollmorgen fully support the EtherCAT® motion bus, without the need for option cards or other gateways as is common with competitive drive options. 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 additional hardware. In addition to EtherCAT®, AKD currently supports CANopen® and in the near future will also support Modbus/TCP.

“As a truly open network protocol, EtherCAT delivers new dimensions of network performance and is a perfect addition to the industry leading Ethernet-centric drive solution,” says Josh Inman, AKD Product Manager, Kollmorgen. “And with AKD, CoE (CAN application protocol over EtherCAT) is tightly integrated at the hardware level thanks to the on-board CAN support. What that means for the machine builder is that no stack-on option modules or intermediary gateways are needed. Our CoE implementation also offers a cleaner migration path from CAN machine networks to higher performing EtherCAT networks.”

Kollmorgen is at the forefront of industry-leading servo technology, as well as the pioneering efforts of EtherCAT based servo-drives. Kollmorgen is an original member of the EtherCAT Technology Group, which was founded November 2003.

AKD servo drives deliver 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 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.

AKD is specifically designed with the versatility, communications, and power that OEMs need to expand machine performance and increase integration speeds. The AKD facilitates true plug-and-play operation with standard Kollmorgenservomotors to get an optimized, high performance system up and running quickly, in less space and for less cost, than lower performing options. Multiple Ethernet connectivity options available from the base hardware support a variety of open and closed protocols, without the need for separate option cards. And a broad power range in a smaller, compact design enables machine builders to use these robust drives with a single interface,” explains Inman.

The AKD is available for 120/240 VAC or 480 VAC 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 168mm x 57mm x 153mm. 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. 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.

“Because the AKD makes it so easy to monitor system performance and share system information, there is virtually no effort required to get a Kollmorgen motor and drive system up and running – and the user friendly interface across the power range makes commissioning and general interactions a truly intuitive process,” says Inman.

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°C to 40°C (up to 55°C with de-rating), and boasts a robust MTBF greater than 340,000 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.
