Flomotion Systems develops and manufactures unique sealless peristaltic pumps that eliminate loss-of prime failures in chemical feed applications. Typical markets served include water & wastewater treatment, chemical, food & dairy, pharmaceutical, pulp & paper, energy management, power and irrigation.

A long-time user of Lenze – AC Tech’s MC Series drives; Flomotion has now incorporated the economical, compact and lightweight SMVector drive in the design of their 2001HEC Series pumps.

The Flomotion 2001HEC Series are rugged, reliable and cost effective industrial hose pumps built to succeed in harsh industrial environments. Several features of the SMVector make it a perfect fit for the job, including a removable terminal cover; easy access for control and power wiring and the fact that it can handle a wide range of operating temperatures from -10 to 55ºC. Last but not least, according to Flomotion, the SMVector offers better protection against electrical shock than any other NEMA 1 controller on the market.

Mounting the SMVector controller directly to the pump allows Flomotion to optimize precious panel space and offer its customers outstanding convenience. The unique EPM or Electronic Programmable Module stores the drive’s parameter configuration greatly simplifying initial setup.

Centrifugal and pumping applications especially those moving fluids or a mixture of wet and dry ingredients present a challenge because the speed is affected by the load. Fluid moving applications require ‘variable speed’ – a drive and motor that can produce the necessary horsepower to move the load at a constant speed. The motor will draw from the drive the amount.

of current it needs to ‘do the job’. The SMVector drive works well in this type of application because the speed can be controlled tightly in vector mode (more torque/less speed) or loosely in V/Hz mode to determine just the right amount of speed.

Lenze – AC Tech has worked closely with a specialist ultrasonic engineering company to solve the problem of making the perfect sliced sausage quickly and with minimal waste. A traditional cured continental sausage is difficult to cut very finely in an automated process because of the adhesive qualities of the meat, when a slice is made with a normal blade it tends to stick to the blade surface after the cut is complete.

The ultrasonic company, more used to sieving and sorting fine powders than chopping sausages has applied it’s high frequency vibration technology to ensure the slices drop away from the blade neatly into the correct place each time. The challenge was to integrate this high-end technology into a slicing machine and still meet the low-cost demands of the food processing industry.

The solution was simple, using a 4 amp PositionServo 940 with encoder feedback to control the position of the blade; the knife could be reciprocated in minimal time and with maximum speed and accuracy. Driving through a precise Lenze MCS servo motor and gearbox combination and a cogged belt drive, the thickness of the slices can be controlled along the entire length of the sausage.

The PositionServo is controlled via a Lenze drive PLC unit and an HMI, in this case a 4” Lenze LCD grey scale touchscreen display. By using an smd drive to power the conventional AC motor that actuates the blade, the machine can be operated with domestic 110 – 240 V supply and still supply a super cost effective combination. Using CANopen to link all the machine control components also allowed minimal wiring to be used and resulted in a highly compact machine that is easy to program and very easy to use.

Features:

Integrated servo, inverter, gearbox

and HMI solution

Complete component compatibility

High speed accurate position control

Precise automation within a low budget

CANopen compatibility

Easy to use

KVAL, a highly specialized manufacturer of door cutting machinery was searching for a better servo drive to improve the cost and performance of its milling machines. A local automation distributor introduced them to the Lenze-AC Tech PositionServo. The challenge was to find a cost competitive drive that would fit the existing profile and yet work with legacy servomotors and resolver feedback.

The solution was found in the PositionServo 941 designed specifically for resolver feedback. The PositionServo 941 was fitted directly to an existing machine and tested immediately in ‘torque mode’. The drive performed beautifully from the first application of power and led to substantial orders soon after. KVAL is recognized as a leader in the design and manufacturing of precision-engineered door machining and millwork equipment. Increased competitiveness within the millwork industry has forced many smaller companies to become more specialized. As a result, KVAL had to alter the design and configuration of many of its machines, the ease-of-use and programming of the PositionServo 941 meant that it was a simple solution to varying machine requirements.

Compatibility with the existing machine set-up was very important and since Lenze-AC Tech PositionServo products are designed to work effectively with the widest range of motors, feedback and machine control systems, it was no problem to fit in with components from three other manufacturers. Cost is an inevitable pressure for any machine manufacturer and KVAL is no different, the fact that the PositionServo provides solid precision performance, but without a price premium sealed the deal.

PositionServo Benefits:

• Works with existing servo motors

• Easy programming

• Resolver or encoder feedback

• Solid technical support

• Rugged performance in harsh environments

• Tight positioning control with

scalable emulated encoder output

Lenze-AC Tech announces the release of EtherNet/IP as an optional communication protocol for the SMVector Drive. According to Mike Bailey, Product Sales Manager at Lenze-AC Tech, the SMVector AC Drive can seamlessly operate on an EtherNet/IP network with the addition of a simple plug-in communication module. “Other network protocols are also available as option modules including CANopen, DeviceNet, Profibus and Modbus RS-485,” states Bailey.

EtherNet/IP is a member of the DeviceNet and ControlNet family of Common Industrial Protocols (CIP) developed by Allen-Bradley (Rockwell Automation – ROK). As a member of the CIP family, EtherNet/IP can utilize the same set of pre-defined common objects, thus making communication between devices from different manufacturers much easier.

According to Lenze-AC Tech company officials, Lenze-AC Tech worked together with Allen-Bradley engineers to ensure complete product compatibility. “We first added EtherNet/IP to our PositionServo Drive and since then, our customers have been looking for EtherNet/IP for their AC Drive Solutions,” says Bailey, and he adds, “Allen-Bradley remains the largest implementer of EtherNet/IP, with most applications in the packaging and automotive markets; providing Allen-Bradley compatibility and multiple communication options for all of our products allows our customers to choose the fieldbus that best fits their automation application as well as their physical network.” Bailey explains that EtherNet/IP is a popular industrial network solution because it can support a nearly unlimited amount of nodes, can be used on a single point connection for configuration and control and permits devices to send and receive messages simultaneously.

It is no secret that the Lenze/AC Tech SMVector Series offers a wide array of functionality for an extremely competitive price. This year, Precision Electric has found it also to be the most reliable and handy drive for most applications. For this reason, the SMVector has been designated Precision Electric’s 2009 online Product of the Year.

The SMVector Series drives are unique in that every product is standard with either a Nema 1, Nema 4, or Nema 4x enclosure. The competitive price margin and standardized Nema enclosed chassis, as well as being a Sensorless Vector drive are a few of the reasons this product line has proven to be so successful. In fact, the SMVector series drive has been so successful that even the manufacturer has increased its’ product pricing and even with the price increase Precision Electric still maintains competitive pricing on all versions of Lenze/AC Tech’s SMVector drive.

The AC Tech/Lenze SMVector product has been designed for diversified applications such as mills, lathes, grinders, mixers, and other applications where high starting torque and/or full torque at full RPM is present. The SMVector drive is available in multiple Horsepower ranging from 0.33HP up to 30HP in Nema 1 Chassis, 0.33HP up to 10HP in Nema 4, and Nema 4x enclosures. Within a few months AC Tech and the Lenze group have announced that the SMVector will also be available up to 15HP in Nema 4 and Nema 4X enclosures.

In this particular case, however, all of the documentation was written in the Swedish language. The drive itself had extensive documentation in the form of manuals that were written in English, but there were no actual machine documents written in English.

The customer had taken the liberty to do a good chunk of translation regarding the essential documents, but as you know, even documentation written in the English language can be hard to understand if you weren’t one of the original engineers.

On projects such as these, I typically like to spend a day or two with my head completely in the program – in this case with the Google Translator at my side. The two most fundamental aspects I was looking for? The homing sequence and the foam gun sequence (as they desired changes to the way the gun operates).

This is the order of operations I took, and it may help some of you out in the future:

1. Gather all of the documentation specific to the job.
2. Gather the requirements of what the customer desires and write them down.
3. Gather all of the tools that will help you break the language barrier (human translators or robot ones)
4. Dig out the I/O list if it is included in the documentation (if it is not, build the list yourself manually)
5. Translate that list to the proper language
6. Cross reference your I/O list to your documentation to seek out a homing sequence in the program
7. Use this as your starting point, as your homing sequence is typically the building block of your program.
8. Next, target the section of the program (referencing the I/O related to it) the customer wants changes too or is having issue with.

This is an excellent starting point for any troubleshooting of PLCs or Motion Controllers outside of your language barrier.  After two days of research and properly building my own documentation – I was able to get the machine running (not without headaches of course) in about one 8 hour day.

Even though the documentation was in a completely different language, this job would have taken weeks had there been no documentation at all – this truly is a testament to the importance of having documentations for your systems – even if that documentation is in a completely different language.
