ISD860 Drives Gives High Servo Performance Control

Based on Technosoft Motionchip DSP technology, ISD860 is a flexible intelligent drive. It has been developed for motion applications that require cost-optimised design, embedded intelligence, networking possibilities and high servo performance control. It is able to drive 12A continuous and 31A peak currents at a supply voltage ranging from 12 to 72V DC, with a PWM of 20 kHz frequency. Embedding motion controller, drive and PLC functionality in one 136 x 84 x 26mm unit, ISD860 controls brushless, DC or linear motors up to 860W continuous/2.2kW peak voltage.

Due to its advanced motion-control algorithms, a precise control of position, speed or torque over a range of dynamic conditions can be achieved. ISD860 works in single-axis, multi-axis or standalone configurations. The drive setup, tuning and motion programming are made simple with Easymotion Studio and Technosoft Motion Language (TML), according to the company. With ISD860, motion programming can be done from a CAN master, via PC/PLC, using the appropriate motion library, or directly at drive level through its built-in motion controller.

The embedded Technosoft Motion Language includes a high-level command protocol, which can be used by the host through the onboard RS232/CAN serial interfaces. A CANopen version of the ISD860 drive, supporting DS-301 and DSP-402 profiles, is also available. In standalone operation, ISD860 can be managed with programmable I/Os or analogue inputs. Using the TML language, multiple operations can be performed with ISD860: setting of various motion modes (profiles, PVT, PT, electronic gearing or camming, etc), change of motion modes and/or parameters, execution of homing sequences or program flow control.

At the same time, IDS860 can handle digital I/O and analogue input signals, execute arithmetic and logic operations, and transfer data between axes. The drive is able to control other axes via motion commands. ISD860 can send commands to a group of axes, or synchronise all the axes from a network. Flexibility and easy implementation make ISD860 suitable for higher-power motion axis-control using modern distributed intelligence architecture. The drive is suitable for cost-sensitive applications, from medical to factory automation, requiring high servo performance and enhanced compactness.

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.
