Enhanced Lenze 8400 Motec Decentralized Drive Technology Features PROFINET and EtherCAT

Lenze Americas, a leading global manufacturer of electrical and mechanical drives, motion control and automation technology, has enhanced its new, decentralized 8400 motec frequency inverter drives to enable plug-and-drive communication via real-time Ethernet networks. The addition of plug-in interfaces for PROFINET and EtherCAT make it possible to seamlessly integrate the relatively simple variable speed 8400 motec drives into existing, high-performance communications networks.

“Our extensive portfolio of integrated gearboxes, motors and motor inverters opens up a wide range of solutions for decentralized drive tasks,” states Craig Dahlquist, Product Leader Applications Engineer, Lenze Americas. “The upgraded 8400 motec drive delivers easy Ethernet communication, without any detours, which offers significant benefits over conventional bus systems.”

The 8400 motec inverter drives are power dense, energy efficient and a dynamic solution for controlling motion at the source. Suitable for applications in plants covering large areas, in particular for decentralized drive solutions in the power range between 0.37 and 3 kW, the 8400 motec inverter constitutes a robust mechatronic unit that offers optimal plant flexibility. The sophisticated design structure comprises three modules—a drive unit, communication unit and wiring unit. The compact size and IP 65 protection rating make the 8400 motec suitable for screw mounting outside the control panel directly on or near the motor—enabling quick commissioning and space savings in the control cabinet.

In comparison with conventional bus systems, which have one data bundle for each separate node, the 8400 motec inverter eliminates the need for extra hardware and an "interpreter" between various protocols. The addition of direct I/O connections to PROFINET and EtherCAT to the communication unit simplifies the process of integrating decentralized Lenze drives into the control system.

“By clarifying the plant automation architecture and streamlining hardware requirements, we are able to drive down total cost of ownership—and bring Lenze ‘easy’ engineering to more of our customers,” adds Dahlquist.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
