New ProductsStepper drive providessoftware control optionAstrosyn reckons its MSST5-Sstepper motor driver will reallyshake up the stepper market.This brand new unit is similar inprice to traditional 5A step-anddirectionmicrostepping drives, butoffers three modes of control: stepand-direction;internal oscillatorspeed control; and full-blown PC orPLC software control.Software control allows it to beset up for running pre-coded routinesrepeatably, but it can also be usefulto use this PC control to carry out onlineoptimisation of parameters suchas acceleration/deceleration rates,speeds and wait times.Even used in ‘dumb’ mode as astraight replacement for a traditionaldrive it has the advantages of highcurrent capacity in a compact sizewithout requiring additional cooling,and very comprehensive protectionssuch as over/under-voltage, overcurrent,over-temperature, andopen/short circuit. The 256 microstepMSST5-S also incorporates featuressuch as automatic system statusmonitoring and display, andcommand signal smoothing.MORE INFORMATION:Enter J395 or visit ‘latest issue stories’ atwww.industrialtechnology.co.uk for furtherdetails from Astrosyn InternationalCANopen intelligent driveNew from Technosoft is a 3kWintelligent servo drive thatembeds motion controller,drive and PLC functionalities in thesame unit. Based on the MotionChiptechnology, IDM3000 is speciallydesigned for servo applicationsrequiring high peak torque, dynamicresponse and flexible integrationfeatures. It can be used to controlUL registered brakingresistor for large drivesREO has added a high voltageunit to its range of brakingresistors. It is ideal fordynamic braking applicationsinvolving large frequency converters oras a charging resistor for railapplications.The NTT606 units are compact,just 345x640mm by 250mm tall,and easy to install with excellentcorrosion protection. They also havegood vibration and shock resistancemaking them especially suitable foruse in traction or shipboardapplications.There are four models in REO’sNTT606 high voltage braking resistorrange which covers from 600 to2700W continuous power ratings, allwith up to x20 maximum ratingbrushless, induction, and DC motorsup to 3kW. IDM3000 drives 10Acontinuous and 30A peak currents, ata supply voltage ranging from 160 to325V.MORE INFORMATION:Enter J396 or visit ‘latest issue stories’ atwww.industrialtechnology.co.uk for furtherdetails from Technosoftoverload capability.
