Success Story from Kollmorgen – Extending Design Life and Performance

Kollmorgen 2G Motion System Simplifies Set-Up in a 50 Axis Meat Slicing Machine
Extending Design Life and Performance
Extending Design Life and PerformanceChallenge
A major producer of food-slicing equipment needed a new servo system solution when the CAN fieldbus module used by its existing controller reached end of life and was no longer available. Exploring the latest fieldbus options, the engineering team chose an EtherCAT solution, which would require a new servo drive. The manufacturer engaged Kollmorgen to provide the technology and co-engineering expertise needed to deliver the required motion control.
The application is extremely complex, requiring the controller to communicate with the slicing machine’s 53 axes to control the feed rate, slicing operation, and positioning of the cut meat or cheese into a “shingle” arrangement ready for final packaging. To deliver the updated machine to market quickly and at the lowest possible cost, the customer wanted to minimize any design changes and to continue using Kollmorgen AKM family motors.
Solution
Already familiar with Kollmorgen’s motion-centric product and support capabilities, the customer opted to incorporate Kollmorgen’s next-generation 2G Motion System choosing the dual-axis AKD2G servo amplifier with EtherCAT connectivity from the many available fieldbus options.
As an early adopter of the AKD2G drive, the customer worked closely with a team of Kollmorgen application specialists to optimize the overall performance of the slicing machine. Given the large number of axes on this machine, the ability to set up each axis efficiently and to diagnose the system quickly was critical to success.
The customer found that the AKD2G’s integrated, front-mounted digital display, unique in the industry, made diagnosing fieldbus connections effortless. The AKD2G WorkBench user interface also significantly simplified setup and commissioning of the system compared to a competitor’s drive that the customer evaluated previously.
Results
The feature set of the Kollmorgen 2G Motion System provides several benefits in an upgraded food-slicing machine that will extend the performance and productivity of the original design over many years.

  • The single-cable design reduces labor and material costs for building the machine
  • The compact dual-axis AKD2G design reduces cabinet space requirements
  • The AKD2G integrated digital display reduces installation costs and simplifies setup and commissioning
  • Compatibility to operate the AKM family of servo motors at its full performance capacity eliminates the need for machine design revisions
  • Functional safety options are integrated in the drive, with no need to add additional components

Universal High-Voltage Gate-Driver For Up To 100A

The TMC6100 is a 3-half-bridge gate-driver for high-voltage BLDC, PMSM, and Servo motors. With a programmable gate current, it drives motors up to 100A using external MOSFETs.
Trinamic - TMC6100Micromech announces a new high-power gate-driver TMC6100 from Trinamic. The compact and cost-effective building block allows full protection and diagnostics via SPI while achieving high-speed operation with minimized switching losses in the power stage.
With a broad voltage range of 8…60V DC and programmable gate current of 0.5A, 1A, or 1.5A, the TMC6100 allows for flexible yet robust designs. Able to drive motors from watt to kilowatt, the gate-driver IC is perfectly suited for industrial drives, factory automation, lab automation, robotics, CNC machines, and finer applications such as surveillance cameras and printers.
“Integrated gate-drivers are perfect for reducing overhead cost in the design process. They not only save time and shorten the bill of materials, they also reduce design complexity,” explains Michael Randt, Founder and CEO of Trinamic. “Forming the interface between the controller and power switches, our gate-drivers improve reliability and increase robustness of the overall system design.”
Besides programmable short and overload and in-system EME optimisation to reduce electromagnetic interference to the absolute minimum, the TMC6100 offers programmable brake before make logic allowing for three or six PWM-channels. With only a few additional components, a standby-mode can be realized for energy-savings, making the TMC6100 ideal for battery-powered devices.
Its versatile interface matches simple BLDC drives with minimum requirements on the microcontroller’s PWM and PMSM control algorithms. As such, the compact gate driver chip perfectly mates any microcontroller, as well as Trinamic’s powerful TMC4671 and TMC8670 FOC controller chips.
The compact QFN package (7x7mm²) with double pin distance for high voltage operation is available from February 2020 via Trinamic’s distribution channels. Fully supported in the company’s modular evaluation system, the gate driver IC is also offered as an evaluation board for quick testing.
Features and Benefits:
  • 3-phase motors up to 100A coil current (external MOSFETs)
  • Voltage range 8 … 60V DC
  • Programmable gate drive (0.5A / 1A / 1.5A)
  • Full protection and diagnostics via SPI interface
  • Gate Off Drive with 1Ω (LS) / 1.3Ω (HS) safe hold off resistance
  • SPI & Stand-Alone operation
  • Charge pump for 100% duty cycle operation
  • Optional BBM break-before-make logic for single line control

Success Story from Kollmorgen – Optimising Bottle Production

Kollmorgen Solution Catapults PET Bottle Blow Molding Machine to Top Producer in the World
Optimising Bottle Production
Optimising Bottle ProductionChallenge
A major bottling operation in China needed to substantially increase output in order to ensure future success in a highly competitive market. For the company’s all-electric linear PET bottle blow molding machine, productivity depends on the ability to quickly index PET preforms into position and then remove the resulting molded bottles. The company engaged Kollmorgen motion experts in early 2019 to help minimize the machine’s indexing time.
Working closely with the customer’s machine design team, Kollmorgen engineers discovered that the indexing performance requirements were overtaxing the existing motor/drive solution. The motor wasn’t able to achieve the desired indexing speed without overheating. The drive was unable to supply the necessary acceleration current and would quickly go into current foldback, further limiting the power needed to meet the desired indexing time.
The only way to prevent overheating and foldback in the existing motor/drive combination was to increase the indexing time – slowing the machine down to the point that bottle-production targets could not be met. While a larger motor might have solved the problem, the machine design was fixed and did not provide the additional space that would be needed.
Solution
Achieving faster indexing times would require more acceleration torque and lower overall inertia. Kollmorgen worked closely with the customer to evaluate the indexing goals and to co-engineer a solution that would deliver the desired machine performance improvements. A Kollmorgen 2G Motion System supplied the additional power needed to dramatically decrease index time while occupying the same space as the prior motor and drive design.
Results
A simple, cost-effective upgrade to the 2G Motion System transformed the PET bottle blow molding machine and reinvigorated the customer’s business.
  • Motor torque increased by 30% without an increase in size.
  • Faster acceleration reduced the indexing time from 1.6 seconds to 1.3 seconds, a 23% improvement.
  • No machine modifications were required to fit the AKM2G servo motor onto the existing motor mount, saving the customer design and documentation time.
  • The machine now produces 156,000 bottles (600 ml) per hour, making it the #1 bottle producer in the world.
