Decentralised Servo Technology Driving Pick-And-Place Machines


Decentralised drives are also continuing to gain ground in the field of servo technology. In assembly and handling technology, products such as the Fluxxtorque 930 Servo Drives From Lenze are proving themselves as compact mechatronic units for positioning trays within a conveyor unit or transporting silicon wafers in the photovoltaic industry. In comparison with pneumatic systems, the travel profiles in servo technology are more dynamic and smoother. They also offer greater flexibility, as the software-based movements can easily be adjusted without costly reconfiguration work. This leads to productivity gains.

With the positioning control integrated in the fluxxtorque 930 Servo Drives, up to 100 motion functions can be processed and saved. The software’s fieldbus monitor allows all parameters of the fieldbus system to be monitored. This functionality enables easy commissioning and the implementation of complex control tasks.

The feedback allows a high degree of positioning accuracy with 4096 increments within one revolution, stopping the zero speed and a speed setting range >1:3000. Brakes are controlled and supplied directly via the fluxxtorque 930 Servo Drives. The servo inverter itself is fitted directly on the B bearing shield of the motors. With its high degree of protection (IP55), it can also be positioned as a standalone version in the direct vicinity on the chassis.

The special design of the motors means that no additional cooling measures are needed for the rated torque throughout the entire speed band. Worm, helical, bevel or planetary gearboxes from Lenze's modular range ensure suitable ratios and compact drive units. Typical uses of mechatronic drive solutions include applications in the field of robotics and handling technology, metering machines and foodstuffs/packaging machines.

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
