Ethernet-Based Control System for DC Drives

At the recent SPS/IPC/Drives show in Nuremberg, Germany, Sprint Electric introduced an Ethernet-based distributed control system for DC drives. Drive.web includes graphical configuration tools that provide diagnostics and configurability of all drives on the network, either locally or remotely via the internet. The graphical tools allow the full configuration of the drives, provide service diagnostics, full documentation and an operator interface for local control, all without the need for a PLC or supervisory computer.

The Drive.web hardware consists of an Ethernet port and processor that takes information dynamically from the drive and makes it available over the Ethernet network. Additional hardware includes interfaces to AC drives and remote I/O modules that provide increased access to the network for other control elements. The configuration software runs on the platform-independent Java operating system and therefore the control system will run on PCs, Macs and Linux based computers.

The software provides graphical configuration and documentation tools for AC and DC drives, start-up/commissioning assistance with real-time information from the drive and network, and a very clean operator interface with dynamic access to machine information. The Drive.web control technology is said to be cost effective in systems of any size and complexity, without the need for a PLC or supervisory computer. Sprint Electric offers a range of DC motor control, with over 150 models covering single- and three phase, regenerative and non-regenerative DC motor applications, together with digital slip-ring motor controllers.

Sprint Electric's full range of products include analogue and digital DC drives from 12 to 2,250A. Whether in retrofits or original equipment, DC drives from Sprint Electric are being used in many different applications, including metal processing, the pulp and paper industry, rubber and plastic processing, lifting equipment, food processing and leisure industries.

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.
