Delta, a world-class provider of industrial automation solutions, today announced the launch of its new compact and high-efficiency servo system ASDA-B3 Series, which offers a user-friendly operation environment with precise motion control functions, a newly- added safe torque off (STO) function, high responsiveness up to 3.1kHz and high positioning precision with over 16.7 million pulses per revolution to optimize production efficiency and output value in a wide range of applications, such as machine tools, electronics, semiconductors, industrial robots, printing, packaging, textiles, warehousing, and medical. Concurrently we have also launched the new generation motor of ECM-B3 Series, offering improved power density, stability, and stiffness while reducing 40% space requirements. Nevertheless, torque has increased 350% and the maximum speed is now 6000 rpm. With the new ASDASoft GUI, the time of commissioning and troubleshooting is shorter.

“Customers across a broad range of manufacturing and industrial automation applications are going to be really excited about our new generation of servo drives,” said Davide Bagnacani, product manager, Industrial Automation Business Group at Delta Electronics EMEA region. “The ASDA-B3 Series is a big step up in performance and we think this will make it attractive for applications, such as machine tools, electronics, semiconductors, industrial robots, printing, packaging, textiles, and warehousing. Moreover, applications that might not have used a servo drive before will see a noticeable increase in throughput. This drive is going to make the decision to use a servo motor much easier.”

A new level of performance
Among the many performance highlights of the new 230VAC ECM-B3 motor from Delta is an auto tuning feature that ensures optimized operation without the need for manual adjustments.

Responsiveness has been bumped up to 3.1 kHz from the 1 kHz of the preceding model. Delta has programmed new motor control algorithms and increased the computing power of the drive to achieve this superior result.

A 40% reduction in settling time also contributes to improved production line productivity. Load tolerances have increased, allowing for better control resolution and system stability as well as higher response bandwidth for the same load conditions.

Further contributing to efficiency are the low cogging torque, increased speed, and lower acceleration and deceleration times. As with the previous line of Delta servo drives, customers can choose from motors with varying inertia ranges to achieve the most efficient inertia ratio.

The new drive enables a number of motion functions, for instance in PR mode. Operators can use up to 99 PR paths for flexible motion command planning. The Capture feature makes it possible to capture coordinates instantly from a single set of digital inputs.

State-of-the-art safety, communications, and control

The ASDA-B3 Series can also operate using several different control modes from traditional pulse train and analog input to the more current fieldbus systems including CANopen and EtherCAT. These different control modes were achieved with three different hardware designs to ensure good segmentation and achieve cost efficiency for the respective application. The EtherCAT command frequency has been raised to 125 µs / 8kHz for greater accuracy.

Positioning is now several orders of magnitude more precise thanks to the 24-bit encoder, which results in 16,777,216 pulses per turn and 46,603 pulses for a single degree. This absolute encoder also retains the motor’s position when the power is off.

Flexibility, compatibility, and enhanced usability
The new configuration application ASDA-Soft employs wizards to guide users through a fast and easy setup procedure. Onboard diagnostics features and usability have been improved with a new and intuitive layout.

The new servo drives of ASDA-B3 Series are compatible with the existing motors of ASDA-A2 Series and ASDA-A3 Series. Configurations are available with IP20 connectors and IP65 connectors are in planning.

It doesn’t take long to find videos of springs being manufactured. The process is almost hypnotic as a series of carefully choreographed motions bend, twist, and form wire into tension, torsion, and compression springs. The equipment used to form these essential metal parts, which are integrated into everything from beds and doors to cars and home appliances, requires significant investment. Hence, when a spring former shows signs of aging, retrofitting to a more modern CNC-controlled system is one potential option.

While retrofitting sounds attractive, allowing the bulk of the machine to be reused, it is difficult to predict all of the possible challenges that will arise. Furthermore, the retrofitted version of the equipment needs to offer additional advantages, such as flexibility, speed enhancements, and an improved user interface. With around 60 spring formers spread across three manufacturing sites, one recent Delta customer faced precisely this dilemma. However, after close support from Delta’s Field Application Engineer Enric Tamarit and his team, together with a trusted system integrator with mechanical engineering expertise, the customer agreed to trial the retrofitting approach.

At its core, the new design used the AX-864E, a CODESYS-based motion controller that is ideal for such complex control applications. The compact, fan-less design, built around an Intel x86 CPU, ensured robust mounting coupled with support for EtherCAT to control the selected drives. The unit also features an HDMI display port, gigabit LAN, four USB interfaces, and a connector for RS-485/422 and a differential input motor encoder. Eight GPIOs provide NPN (sink) or PNP (source) control or input signals dependent on the model chosen. A watchdog timer, configurable through the BIOS, ensures the system automatically resets in the event of abnormal operation. Additionally, a range of security features, including BIOS passwords and Delta’s PAC Tool for restricting writes to the integrated solid-state drive, are also included. Thanks to its support for CODESYS, an industry-standard IEC 61131-3 PLC language, the control system software was rapidly iterated to optimize the implementation.

The wire forming was realized with ECMA Series servo motors. Their state-of-the-art design provides a high torque-to-size ratio, low flux loss, and delivers low cogging suited to the smooth motion control required for spring manufacture. They could also be adapted to different spring-forming equipment needs thanks to a range of shaft options and encoders. Coupled with ASDA-A2 Series servo drives, connected via high-speed EtherCAT, simultaneous control of the servo motors was ensured. The characteristics needed for the retrofitted design were easily achieved thanks to the available high precision control, with a 1 kHz frequency response and 1 ms settling times, and superlative vibration suppression. Programmable positioning modes (Pr Mode) also allow up to 64 internal position settings, supporting continuous motion control.

An essential aspect of the retrofit was an improved user interface, allowing operators to configure the desired spring from a choice of recipes. With a 7-inch color TFT display, the DOP-H07 Series provided the flexibility needed by machine operators. This IP55 rated handheld device weighs just 750 g and includes an emergency stop button together with a hook for convenient storage when no longer in use. Connected to the AX-864E via a TCP Modbus, the handheld display allows simultaneous configuration of the spring former while overseeing the actions executed by the servos. Delta’s DOPSoft configuration software enables visually appealing, clear, and easy-to-use interfaces in multiple languages, ensuring simplicity for users. Simulation of the production process was also implemented, saving time and resources before committing to manufacturing.

The retrofitted electronic CAM spring former provides a more streamlined operating experience. Switching between the manufacture of different spring types is simplified, thanks to the user-friendly, recipe-style selection offered by the human-machine interface (HMI). Furthermore, new recipes can be easily developed by extending and modifying existing designs as and when required. In operation, the upgraded solution proved to be significantly more efficient. Tooling changes to manufacture a different spring previously required a day of effort. This has been reduced to half a day with the new approach. Furthermore, productivity has been improved by 50% in most cases, while the most straightforward spring designs can now be manufactured at double the previous rate.

Although the initial retrofit has taken around a year of close cooperation and work to complete, the results have been so impressive that the customer has decided to continue upgrading further spring formers. Because a CODESYS-capable motion controller was chosen, coupled with Delta’s easy-to-integrate HMI, servo drives, and servos, this approach will continue to be a cost-effective and reliable alternative to machine replacement.

Bread. Just thinking of the word pushes your olfactory senses to imagine yeast-based delights at the counter of your favorite bakery. But baking the perfect loaf, and in large enough quantities, demands furnaces that accurately control the process from beginning to end. This was precisely the task faced by Mechatronics Ltd., a system integrator and official distributor of Delta Motion, Drive, Control, and Robotics products based in Bulgaria.

The requirements for the bread furnace machine defined four temperature zones. The first zone is especially powerful to compensate for the cooled conveyor belt and the relatively cool loaf entering the oven. At this step, steam is also injected into the furnace to give it that freshly-baked sheen. It is followed by three temperature-controllable baking zones that are carefully controlled for baking the optimal loaf. The conveyor belt of this traveling oven design must also be held at the correct speed throughout the process. Rounding off the specifications was a human-machine interface (HMI) to configure the baking process, deliver temperature status of each zone, and output any error status information.

For the HMI, the team selected the Advanced HMI DOP-107WV from the DOP-100 Series. This touch-based control panel features a 16:9 7” color TFT screen with a modern-looking, narrow frame. Its multilingual support meant it was well-suited for the target market, while user-friendly editing software ensured that the final user interface was easy to navigate. With several RS-485 capable COM ports, it integrated perfectly with the other components selected for the furnace. Considering the operating environment, the flat, wipeable surface of the DOP-107WV proved the ideal choice for a dusty bakery. Control for the conveyor was implemented using an MS300 Series inverter. This AC motor variable frequency drive (VFD) also supported the RS-485 Modbus interface and is ideal for open-loop control of IM and PM motors.

Of course, the quality of the bake is ultimately defined by the furnace. Special attention was given to selecting the optimal control approach for the seven heating elements used. After careful deliberation, the DTC1000 Temperature Controller was selected as the main controller, with DTC2000 controllers used in parallel for the remaining six heaters. These are also connected to the Modbus. The selection of established, reliable components, along with the careful programming, were critical in delivering a low-maintenance design that could be operated 24/7.

To provide optimal temperature regulation, the auto-tuning function of the DTC1000/2000 was used. The inputs are acquired from third-party PT100 temperature sensors while control of the heating elements is implemented with solid-state relays. Auto-tuning uses a training process to configure the closed-loop PID controller once the sensors and heaters are installed in this 250 kW furnace. Further complicating the implementation is the dual heating and sensing of the last three baking zones. With one heater above the conveyor and the other below, each needs to be set to a different temperature. Spare outputs from the Delta Temperature Controllers were available and linked to relays for audible and visible alarm signals. These signals were also replicated in the DOP-107WV HMI.

Closely coupled with the quality of the bake is the speed control of the conveyor belt. The MS300 VFD is linked to an inductive proximity sensor that is easy to clean and remains accurate in the dusty baking environment. Installed closed to the gears, the built-in programmable logic controller (PLC) of the MS300 is configured to monitor and calculate the conveyor speed. This is continuously compared it to the setpoint defined in the HMI. Thus, the end-customer only needs to set the desired baking time, the required temperature, and then press run to start baking.

The Mechatronics Ltd. team benefited from the broad range of industrial automation solutions in the Delta portfolio. Integration of the VFD, HMI, and Temperature Controller was simplified thanks to the out-of-the-box interoperability and connectivity of the components selected.

“Most people would assume that baking bread is very simple. On the contrary, the bread furnace project has highlighted the skill required of both bakers and engineers to create a machine that delivers the perfect loaf. The auto-tuning function of the DTC1000/2000 played a large part in ensuring that bakers can deliver a quality product every batch, by providing excellent temperature control,” said Victor Ogedegbe, Field Application Engineer at Delta.

“Construction of the bread furnace was simplified by the availability of components that are interoperable and fulfilled the requirements demanded by our customers. Accurate temperature control was most critical for us, and the Delta team's support was essential in configuring the DTC1000/2000 auto-tuning function. This assistance contributed to the project moving from the initial design stage to full production in just seven months,” said Toma Draganov, Automation engineer at Mechatronics Ltd.
