In our previous blog, we explored what SCS open link is and how well it fits with advancing drive systems. This fully digital, single-cable protocol provides the servo-motor market with a much-needed nonproprietary standard—creating greater flexibility when it comes to encoder selection. But the advantages don’t end there.

Let’s take a closer look at how SCS open link benefits end-users, as well as drive and machine manufacturers:

Flexible installation for end-users. SCS open link supports two- and four-wire applications, reducing the number of connectors and making installation fast and easy. For one, this design saves on material costs and the labor required to get things up and running. It also reduces installation space, which comes in handy in tight spaces. And finally, less components ultimately means less weight, which boosts the energy efficiency of your system.

A fast, reliable interface for drive manufacturers. SCS open link features fast transmission rates up to 10 MBaud and short controller cycles up to 32 KHz—opening even more application possibilities for manufacturers. Because it utilizes RS-485 as its transmission standard, you can use it reliably over distances up to 100 m and in electrically noisy applications, such as industrial control systems. It is also downward compatible, allowing seamless interoperability with legacy systems.

Future-ready technology for machine manufacturers. SCS open link helps you keep up with the demands of Industry 4.0 and the developing Industrial Internet of Things (IIoT). It lets you connect additional secondary sensors, for example, as well as add condition monitoring capabilities to your drive system. Its single-cable design also saves on space—a compelling advantage as the industry shifts toward developing and deploying smaller drive systems.

In today’s increasingly automated and smarter factories, servo-driven systems have become more prevalent than ever. Until now, the electrical interface limited the kind of encoder you could use in these applications-but all that is changing with SCS open link. This once-proprietary standard is now publicly available, ensuring the compatibility of devices from different manufacturers and providing you with greater flexibility when it comes to selecting your encoder.

Let’s take a closer look at this innovative interface:

What is SCS open link? A fully digital protocol, SCS open link transmits both energy and data through a single connection cable-enabling the high-performance exchange of bi-directional data between a rotary or linear motor feedback encoder and the drive controller.

Which technologies does it support? SCS open link is suitable for single and multiturn encoders, sensors, actuators and linear scales and supports 2- and 4-wire applications with cable lengths to 100 m. This interface, safety-certified up to SIL3, also offers fast, interference-free data transmission up to 10 MBaud and controller cycles up to 32 KHz.

What new possibilities does it open up? SCS open link integrates future-proof technology and is therefore a compelling interface for advancing drive systems. The interface makes it easy to develop and deploy Smart Motor technology, for example, which provides you with motor analytics and permanent condition monitoring. This ability to detect and correct faults at an early stage leads to improvements in plant performance.

In our next blog, we’ll delve into the many advantages of SCS open link, including how it benefits end users and drive and machine manufacturers. In the meantime, visit our SCS solutions page to learn more.

If you design and manufacture motors and drive systems, you know that factory automation and servo motors go hand in hand. Nowadays, you can expect to find servo motors running on more machine axes than ever in packaging, semiconductor manufacturing, robotics and other applications requiring precise positioning of a load. In fact, as automation continues to take over the factory floor, it’s not surprising that the servo motor market is projected to grow as much as 10 percent a year.

This trend means you’ll need a motor feedback system that can operate servo motors of various sizes, performance levels, electrical interfaces and technical requirements, such as high rotational speed and high temperatures.

Our new Sendix S36 motor feedback system meets these requirements-and more. Here’s a rundown of what you can expect:

Compact size will save you space and cost. Drive systems are increasingly becoming more compact. With its space-saving 36-mm housing, the S36 is equipped to handle all singleturn and multiturn variants, as well as all medium to high power ranges. By reducing the number of motor variants, the S36 saves you space and operating costs.

High signal quality increases motor stability. Using phased array sensor technology, S36 devices achieve a resolution up to 2,048 ppr sin/cos or 24 bits (fully digital), ensuring high signal quality even in the presence of shock and vibration.

Robust design can take on harsh factory environments. The S36 is designed to reliably operate your motors in harsh, unforgiving environments. For one, it integrates our proprietary Safety-Lock™ design, which consists of interlocked bearings, strengthened outer bearings and large bearing size relative to the size of the encoder. This feature also enables the S36 to overcome two common threats to encoder lifecycle: heavy vibration loads and misalignment due to installation errors.

Other robust mechanical features include a wide temperature range, torque-proof stator coupling and vibration-proof plug connectors. The S36 also provides the latest in gear technology, which is preferred over a battery solution. Thanks to its three gear stages, the S36 achieves high rotational speeds, accurate positioning and long service life.

Interface variety gives you more flexibility than ever. No longer will the electrical interface be the limiting factor in the kind of feedback system you select for your drive application. S36 devices support all classical interfaces, including RS485 + Sin/Cos (HIPERFACE® compatible), BiSS, BiSS Safety, BiSS-Line and HIPERFACE DSL®, as well as open-source interfaces for the Single Cable Solution (SCS).

Here’s a quick rundown of some of them:

  • HIPERFACE DSL®: Transmits data to the drive and enables motor-controller communication via two wires integrated into one motor cable up to 100-m long and requiring just one motor connection.
  • BiSS Interface: Hardware compatible to the Serial Synchronous Interface (SSI) standard, this interface includes a one-cable implementation.
  • SCS open link: A motor feedback interface for high-performance, bi-directional data exchange supporting 2- and 4-wire applications with cable lengths to 100 m. SCS also integrates future-proof technology, making it a compelling interface for advancing drive systems: it includes a fully digital protocol, is certified up to SIL3 and is Smart Motor-suitable.

This encoder recently won an award. Check out our Press Release.

As the Industrial Internet of Things (IIoT) continues to transform manufacturing operations into Smart Factories, machines must exchange information with other machines on multiple levels. When designers select an encoder, not only must they consider how it interacts with the drive but also how it communicates as part of a larger intelligent sensor network.

Enterprises are increasingly relying more on the cloud to process important machine data.
Therefore, the IIoT demands encoders that can forward that critical process, monitoring and diagnostic data to the cloud for enterprise-wide information handling without restriction.

The OPC-UA (Open Platform Communications – Unified Architecture) is becoming an important communication protocol for the Industrial IoT. Encoders that leverage this architecture are able to transmit parameters such as speed, position, acceleration, temperature and operating time along with IP information directly to the cloud while lifting the burden of information handling from the existing machine automation infrastructure. This open architecture does not limit developers to a specific operating system or programming language, and it’s free to implementers—no fees required.

Kuebler’s recently introduced EtherNet/IP encoder series integrates the OPC-UA interface, giving designers a gateway to the cloud with the freedom of open, cross-system communications throughout the plant. Besides providing interoperability for enterprise-wide industrial automation, EtherNet/IP encoders offer several other benefits:

This series of four single-turn and multi-turn optical encoders boasts 1-ms RPI (requested packet interval) times so they can transmit position data faster than many conventional encoders. They plug directly into the network and are software configurable, making installation quick and easy. They’re also highly reliable thanks to redundant signal paths that let them continue running even during a cable break or signal interruption. Users can choose different network interface speeds and flexible network architectures based on the available Ethernet installation options, such as copper, fiber, fiber ring and wireless.

Since the IIoT ultimately fulfills its promise through real-time data exchange across the plant, encoders that forward data from the physical layer to the cloud while allowing developers to freely integrate them into the larger network will lead the way to the smart factory of the future.

NORD Drivesystems, a company that manufacturers drive technology for mechanical and electronic applications, uses our Sendix 5000/5020 incremental encoders for many of their motor-driven systems. Thanks to their rugged design features, these encoders can take on the kind of demanding applications NORD motors are often used for—from conveyors to overhead hoists.

To integrate the Sendix encoders into one of their motors, NORD engineers recently had to overcome several space-related design challenges. The encoder had to mount on the back of the motor underneath a protective fan shroud and, as a result, required a smaller mounting depth, as well as new cable outlet and termination solutions.

Here’s how Kuebler engineers overcame these challenges:

A Custom Solution For Limited Space. To meet the motor’s requirements, Kuebler engineers changed the location of the clamping ring, moving it from the front to the back for easier installation. They also developed a special tangential cable outlet, in which the cable—once it attaches to the encoder—comes out at an angle.

Engineers also needed to figure out how to terminate the cable where it exited the fan shroud. They decided to use a bulkhead connector, as it provided easier termination and cleaner installation of the cabling.

Thanks to these slight design modifications, engineers successfully mounted the encoder to the motor despite the limited space. The motor has since been used in a variety of demanding applications, including conveyors, packaging machines, overhead hoists and large industrial doors.

Inclinometers, which measure an object’s angle of tilt, are often used on cranes and other heavy-duty equipment. This, coupled with the fact that they’re primarily used outside, means they need to operate reliably under demanding conditions.

For these reasons, robustness and safety are key—and it’s important for your inclinometer to provide both. For an example of inclinometers that meet both of these requirements, take a look at our new IN81 and IN88 series.

Ruggedized For Use Outdoors. Both the IN81 and IN88 series measure 2-dimensional inclinations at a range of ±85° and 1-dimensional inclinations from 0°to 360°. With their IP67 and IP69k ratings, they can withstand exposure to dust, water and high-pressure, high-temperature washdown during routine equipment cleaning. And, enclosed in a full-metal cast housing, the IN81 and IN88 can operate in temperatures from -40° to +85°C and endure shock and vibration levels up to 100 g and 10 g, respectively. Together, these robust features make the IN81 and IN88 suitable for use outdoors, including in mobile automation applications.

Stackable Design Improves System Reliability. What makes the IN81 and IN88 truly unique is their stackability, which comes in handy if you’re looking to add redundancy to your system. You might opt for this kind of setup if you’re working with cranes or hoists, for example. In these applications, the stacked inclinometers operate as a safety mechanism: each device sends an independent signal that corroborates what the other devices in the system are saying.

The IN81 and IN88 include other important safety features as well. For one, they meet several EMC and immunity standards for applications in measurement, control and laboratory settings, as well as industrial environments. Circuits also include reverse polarity protection.

The IN81 and IN88 are versatile inclinometers that support M12 cable connections and a variety of Analog, CANopen and Modbus interfaces.

To avoid downtime and costly repairs to your motor-driven systems, make sure you pay attention to the construction of your incremental encoders. The best encoders will have design features that allow them to resist shock and vibration loads, as well as overcome any installation errors that introduce misalignment.

It’s important to select incremental encoders that are designed for rugged conditions, such as our Sendix 5000 and 5020 models. Both encoders have several robust and versatile design features that make them ideal for demanding outdoor applications.

Robust Mechanical Design. Thanks to our proprietary Safety-Lock™ design, both Sendix models overcome two common threats to encoder lifecycle: heavy vibration loads and misalignment due to installation errors. This robust mechanical design integrates interlocked bearings, strengthened outer bearings and large bearing size relative to the size of the encoder.

Additionally, the encoders’ solid die-cast housing, with its IP67 protection rating, stays sealed even when subjected to harsh environmental conditions.

Other robust mechanical features that help avoid field breakdowns include:

  • Wide temperature range of -40°C to +85°C
  • High shaft load capacity: 80 N (radial) and 40 N (axial)
  • Maximum speed of 6000 revolutions per minute
  • Magnetic field resistance
  • Optional seawater-resistant version

Versatility And Variety. Sendix 5000 and 5020 encoders, available in shaft and hollow shaft versions, respectively, are compatible with all U.S. and European standards. You can also use them with a variety of mounting accessories, including cylindrical pins, flanges, assembly bells and isolation inserts, which increase the lifespan of your encoder by preventing electrical current from passing through the bearings.

Sendix 5000 and 5020 encoders support M23, M12 or MIL cable connections, as well as Push-Pull, RS422 or Open Collector interfaces.

In many applications, you’ll need to know an object’s angle of tilt. That’s where inclinometers come in. Because these sensors are typically used outdoors—in commercial vehicles, cranes, hoists and solar installations, for example—it’s important to select inclinometers that can work reliably in harsh environments.

Here are a few features to look for:

Versatile And User-Friendly. Two important specifications to consider when selecting an inclinometer is its measuring range and number of axes. The IN81 series measures 2-dimensional inclinations at a range of ±85° or 1-dimensional inclinations from 0° to 360°. In addition, these inclinometers require minimal installation space and can be easily mounted anywhere, thanks to their compact size.

Robust Construction. Inclinometers like the IN81 series are designed to take on the toughest environments. These IP67- and IP69k-rated devices can withstand exposure to dust and water. They can also be used in applications—cement trucks and other heavy-duty road vehicles, for example—where high-pressure, high-temperature washdown is regularly used to sanitize or clean equipment.

And with their rugged metal housing, these inclinometers can operate at a wide temperature range of -40° to +85°C and are designed to withstand shock and vibration levels up to 100 g and 10 g, respectively.

High Accuracy. While balancing versatility and robustness, it’s important to select an inclinometer that can make high-precision angular measurements—with most electronic inclinometers typically falling somewhere between 0.01° and 2°. Not only do devices from Kuebler have an output resolution of 0.01°, but they also feature programmable vibration suppression, as well as high sampling, high bandwidth and high calibration accuracy.
