Drive Profile Aids Communications Integration

A variable-speed-drive profile is available for the CC-Link open industrial fieldbus protocol and is said to reduce the time and cost required to integrate drives into open communications networks. The Anybus-Compactcom drive profile is said to improve the functionality of the software so that compliance with the latest communication standards for drives is ensured. Device profiles specify how a network communication system can used for devices for a specific application area.

The use of profiles reduces engineering costs, since the meaning of parameters related to the application is precisely specified. All the Anybus-CC drive-profile modules have the same hardware interchangeability as standard Anybus-CC modules. Their software interface permits a standardised access to the drive parameters, independent of the network type. The drive-profile software interface functions are similar to the standard Anybus-CC modules, but offer enhanced features.

Automation devices that have an existing standard Anybus-CC slot need only to upgrade the software interface before their first use. After this, they can use the full range of enhanced standard modules and drive-profile modules for an even more flexible communication interface. The Anybus-Compactcom drive profile CC-Link communication module provides the inverter drive with instant CC-Link connectivity via the uniform Anybus-Compactcom host interface.

Any device that supports this standard can take advantage of the features provided by the module, allowing network integration regardless of network type. The module supports drive operations according to the inverter profile of CC-Link. When used in standard mode, the module supports CC-Link version 1.1, but during initialisation it can be configured for CC-Link version 2.0 functionality.

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.
