ABB has developed a user-friendly drive system package (DCS 400, DMI Motor) to meet the demands of machine builders.
Our aim is to offer the best combination of reliable products at the most affordable price, backed by on-time delivery, good partnership and fast response to inquiries. At the heart of the drive package is the DCS 400 – a new generation of DC drives specifically designed to meet the ever-changing needs of machine builders.
“Total ease of use” was the foundation of this drive’s development. The result is a drive that is:
|Power and Field:||230 – 500 VAC, 3-phase|
|Input Frequency:||50 – 60 Hz|
|Converter Fan:||115/230 VAC, single-phase|
|Control Power:||115/230 VAC, single-phase|
|Digital Inputs:||Eight (8), 24 VDC|
|Digital Outputs:||Four (4), 24 VDC
One (1) relay
|Analog Inputs:||Two (2), ±10 VDC, 12 bit|
|Analog Outputs:||Two (2), ±10 VDC, 12 bit|
The DCS 400’s compact design brings substantial space savings to machine builders, allowing them to integrate more accessories within the same space.
ABB’s DCS 500 Digital Drive is designed to be used in both simple and complex applications. Advanced Control panel operation and easy Application Block Programming make the drive flexible and user friendly.
The DCS 500 takes advantage of ABB’s extensive experience in DC drives. High quality components together with the latest production technology guarantee reliable operation and customer satisfaction. Performance with flexibility for industrial or commercial applications.
The DCS500 can be controlled and monitored from either a PC-based Commissioning and Maintenance Tool or from a Control Panel which can be moved from one drive to another.
Drive applications can easily be changed with programmable function blocks. Application programs allow the drive to be configured without additional hardware. Changes can easily be made via the Control Panel.

More AC Drive information…
Do you have ac motors in your facility?
Do these motors need a variable output?
Do you use mechanical means to vary the output?
If you anwsered yes to these questions, you need to install variable frequency drives on these ac motors.
If you are not using VFD’s you are wasting energy and throwing money out the window.
In the United States 50% of the total electrical energy generated is consumed by rotating equipment. 65% of this total is consumed by centrifugal or flow related applications such as fans, blowers, compressors, and pumps according to current estimates. Variable speed drive technology offers a cost-effective method to match driver speed to load demands and represents a state-of-the-art opportunity to reduce operating costs and improve overall productivity.
ower Formers Engineers is an OEM that custom packages, integrates and engineers AC Variable Frequency Drives (VFD), DC Variable Speed Drives (VSD) and AC Drive Controllers. Our drive systems integrate top of the line manufacturers, like ABB, Emerson (Control Techniques & Saftronics / Fincor), Siemens and WEG to name a few. Our added value custom drive packages are built to your specifications for your application.
What is a Variable Frequency Drive?
You can divide the world of electronic motor drives into two categories: AC and DC, a motor drive controls the speed, torque, direction and resulting horsepower of a motor. AC drives control AC induction motors. DC drives typically controls a shunt wound DC motor, which has separate armature and field circuits.
Motor drives are also known as DC Drives, AC Drives, SCR Drives (Silicon Controlled Rectifier Drive), Variable Frequency Drives, Variable Speed Drives, Adjustable Speed Drives, Electric Motor Drives, Electronic Motor Drives, AC Motor Controllers, AC Inverters, Pulse Width Modulation (PWM) Drives and a few other names.
|DC Variable Speed Drive|
|Torque control and limiting||Brush life commutation maintenance.|
|Wide speed range (under 5000 RPM)||Motor high speed limit (high speeds use expensive gear boxes)|
|Trimming capabilities||Expensive large HP motors|
|Constant HP capabilities||Power system harmonics|
|True 4-quadrant regenerative energy conversion||NA|
|Few distance limitations||NA|
|Cost (especially single phase sizes)||NA|
The AC Variable Frequency Drive market is huge, due to the great advances in highly reliable AC power electronics and high power microprocessors. The Flux Vector AC Drive for example, can compete on an application basis that DC Drives would in earlier years be required.
|AC Variable Frequency Drive|
|Improved efficiency||Distance limitations|
|Low motor maintenance||Large system designs (high HP drive foot prints)|
|Tight control||Cost (encoder feedback)|
|Digital control||Expensive regenerative braking|
|High speed capabilities||Power system harmonics|
|Reversing capability without extra power elements||NA|
Even though AC Variable Frequency Drives are readily replacing DC Drives and motors, there is still a large base of DC equipment that has to be supported by experienced technicians. Joliet Technologies believes that by not abandoning the DC market we can better serve our customer base demands. For example, older machines with multiple exciting DC Analog drives and motors may be a great candidate for retrofitting newer digital DC drive equipment. Saving cost and down time.
