LG Motion Distributes Motion Control Technology

LG Motion is now offering motion control technology from Precision Microdynamics (PMDI), a machinery manufacturer specialising in high-speed distributed motion control, data transfer and acquisition. PMDI's newly released Polaris is a complete motion and machine control system than runs on the company's own real-time Gbit/s Mercury network. With multi-axis motion controllers, servo amplifiers for brushed and brushless motors and high-bandwidth galvanometers and voice coil actuators, plus digital and analogue I/O modules, Polaris is said to complement LG Motion's range of positioning mechanics to enable customised automated sub-systems for applications across industry and research.

The Polaris is also targeted at system integrators and original equipment manufacturers (OEMs) who require the flexibility of a distributed motion and machine control platform for their own automated machinery. The Gbps Ethernet-based Mercury communication (patent pending) is a high-speed real-time network offering the synchronisation of data acquisition and control in all amplifier and I/O modules to within 10ns and motion capability to 124 axes.

For even faster timing co-ordination, the optional Pulsar module further reduces the sampling jitter to achieve sub-nanosecond synchronisation. With the servo loop performed in the amplifier, enabling rates of up to 200kHz, advanced system performance features include advanced motion path planning, cubic splines, PVT profiles and jerk limitation. Both the motion controller and the amplifier feature full 64-bit double-floating-point calculations for high levels of positioning accuracy, fast servo feedback rates and submicron resolution for improved form and finish combined with high speed and acceleration controls that enable faster production throughput.

PMDI's Polaris motion control system includes multi-threaded customisable software that allows users to create their own scripts and user-defined G-Codes. A powerful graphical user interface is included that runs on Windows systems. The range is fully supported with setup, status, tuning, tutorials and help wizards that are designed to enable fast and straightforward system commissioning and programming.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
