The new EL7201 servo terminal with resolver interfaces offers high servo performance in an exceptionally compact design. In addition, its integrated fast EtherCAT control technology, with PI speed control and field-oriented current, can support highly dynamic positioning tasks. Aside from the direct connection of a resolver and motor, a motor holding brake connection is also possible.

“The new EL7201 servo terminal is a true game-changer in the area of servo technology,” remarked Graham Harris, President, Beckhoff Automation.

“Small servo drives have been a popular technology for years and the EL7201 is a major evolution of this trend. Machine builders and manufacturers now have the option to control small servos with a 12 mm device.”

Permanent magnet synchronous motors, featuring a rated current of up to four A, can be connected to the new terminal as loads.

The new servo terminal provides maximum operational reliability, as it monitors various parameters, including undervoltage and overvoltage, overcurrent, motor load or terminal temperature.

Since it is fully integrated into Beckhoff’s TwinCAT automation software, the EL7201 servo terminal allows convenient parameterization. For third-party masters, parameterization occurs through the CAN over EtherCAT profile (CoE).

Motion Control Tips

Especially where there are lots of cables and wiring, cable management becomes an issue. A simple form of cable management uses twist-tie type bundlers that tie together groups of wires and cables. These are low cost and easy to use. The problem is that with more and more cabling, they become impractical. Also, if the wiring and cabling have to be suspended, bundling them together may pose weight problems which cause sagging and put undue strain on the cables.

Using cable carriers is another option. Cable carriers are essentially structures designed to house cables. The structures themselves can be made of many materials such as plastic, steel, or a metal alloy. Cable carriers are used to protect cables and hoses on moving machinery. They prevent tangling and increase safety by not having cables susceptible to getting caught in moving parts of a machine. Applications for cable carriers can range from machine tools and robotics to cleanroom applications and large industrial equipment like cranes and other construction machinery.

Carriers can house a large volume of cables and wires and support the weight of them all without sagging or putting stress on the cabling. They also make managing and routing the cables through a machine or factory much simpler and provide easy access for troubleshooting or maintenance as well.

Selecting the right kind of cable carrier for an application starts with a few simple guidelines. The most important points to consider are the specifics of the application. These include the length of travel, the number of cables or hoses, the size and weight of the cables, the required speed and acceleration and environmental factors such as exposure to any debris, excessive heat or chemicals. Knowing the weight of the cables ensures that the carrier won’t fail by snapping in two.

Cable carrier styles can be either open or closed. Open varieties allow for easy access to the cables and visible access as well, whereas closed carriers seal off the cables from the environment to protect from environmental contaminants such as metal filings.

Environmental conditions play a large part in selecting a cable carrier. If the application is in a dirty or contaminated area, an enclosed carrier is the best choice. An open carrier is lightweight and makes inspecting and replacing cables easier.

Another important consideration is the bend radius of the cable carrier. Bend radius is measured from the center of the curve loop to the center of the pivot pin on the side link. A larger bend radius means less stress on the cable and a longer service life.

“DC motor commutation is accomplished via brushes, which leads to electrical arcing during rotation. To reduce electro erosion while extending commutator life, Portescap innovated the proprietary REE coil system to reduce the effective inductivity of brush commutation by optimizing the mutual induction of the coil segments,” said Dave Beckstoffer, Project Manager for Strategic Markets.

“Portescap conducted tests on motors with and without REE coil optimization and found that commutator surface wear with REE coils showed improvements ranging from 100 to 300 percent.”

Aside from the benefits of REE technology, the company’s brush DC coreless motors also offers salient features such as no cogging, low moment of inertia, high efficiency, compact commutation and low friction resulting in high acceleration, higher continuous torque and very low joule losses. The motors deliver maximum continuous torque ranging between 0.66 mNm and 158.6 mNm, a low motor regulation factor (R/K2) of .3 103/Nms, and no load speed that range from 11,000 RPM (eight mm) to 5,500 RPM (35 mm).

Its intrinsically safe motor operation is especially important in ambulatory applications subject to extra-ordinary operating conditions and/or harsh environments. Typical applications include environmental analyzers, fuel cells and gas analyzers.

This highly efficient, lightweight coreless DC motors also serves as an ideal solution for miniature pump manufacturers faced with issues of intrinsic safety in portable applications.

With modules ideally suited for various applications including boiler protection, emergency shutdown as well as fire and gas equipment, the ET 200iSP’s isolating transformer is a bus isolating transformer that creates an intrinsically safe PROFIBUS DP communications network.

The terminal modules of the I/O system are plugged with PROFIBUS DP interface modules, function modules — which include an explosion proof power supply — and a maximum of 32 electronics modules. The ability of the I/O system to “Hot Swap” the electronic module enables customers to avoid costly downtime when stopping the controller. The PROFIBUS DP interface module’s firmware can be upgraded over PROFIBUS DP or using a micro memory card (MMC).

Maximum uptime is available with PROFIBUS DP, while redundant power supplies allow for redundancy. When utilized in a redundant configuration, the I/O system’s power supplies can be replaced and hot swapped under power even in highly hazardous locations.

With an analog signal of four to 20 mA, the ET 200iSP links process devices with Highway Addressable Remote Transducer (HART) technology. A routing function within the PROFIBUS DP allows a central station to transparently access HART process devices. Thus, more process instruments, including fill-level, temperature, flow rate measuring equipment and pressure, can be configured and accessed.

The new electric tube bender is designed with two multiple-tool heads fitted on the rotating frame’s opposite sides. After bending utilizing one or more of its tools, the head retracts while a combination of rotational and transverse movement prepares the left-hand head for the next bending operations.

Aside from offering various innovations that enhances the versatility and precision of the bending capability, the new machine also comes with a movable platen and long pressure die that enables it to create complex shapes that includes a 180 degree bend performed in a single rapid and continuous operation.

The all-electric, servomotor-controlled architecture of the machine provides a comprehensive programmability across the part fabrication cycle. The tube bending dies’ forces and position can be accurately controlled to generate the highest quality and accuracy of shape fabrication and end result.

At the center of the Unison Breeze-Revolution is a motion system and real-time machine anchored on the deterministic Ethernet-compatible Powerlink protocol. The servomotor drives are connected to the control bending operations by a 100 Mbits/second network. The network’s speed allows it to rapidly coordinate the various movements of the servomotor axes utilized during bending to effectively enhance the speed of bending.

Unison can also provide the new left-hand/right-hand rotating head architecture on electric tube bending machines that can handle tubing with a maximum diameter of 180 mm (7 inches).
