Absolute Encoders: A Necessary Component of the Industrial World

Posted by Advanced Controls & Distribution on Sep 25, 2017 2:14:56 PM

Encoders are a necessary component of the industrial world, and can be found supporting a range of tasks, from positioning a patient in an MRI machine to bottling beverages at high speed. An absolute encoder, as the name suggest keeps the record of its position following some absolute coordinate system. An absolute encoder produces digital words in order to identify its location, and is often used in mission-critical applications that require greater speed and accuracy.

Siemens Drives Energy Efficiency

Posted by Advanced Controls & Distribution on Mar 23, 2017 9:09:27 AM

Did you know that drives account for almost 70% of the total energy requirement of every industrial plant? Even a small amount of inefficient loading can cause heavy economical losses to the plant and the parent company. However, with more efficient methods, greater profits and longevity in machines can be a result.

Benefits of the Smaller Design of the GH180

Posted by Advanced Controls & Distribution on Mar 14, 2017 8:20:43 AM

Space is always at a premium.

Whether it be at home or at a very large industrial complex, space is always at a premium. We start out with a layout which has plenty of space for expansion but soon, and invariably, we start running out of space. There often is a need to replace a faulty piece of equipment, and commonly the new equipment will not fit into the available space.

SINAMICS PERFECT HARMONY GH180

Posted by Tenisha Corrales on Mar 2, 2017 11:39:45 AM

The SINAMICS PERFECT HARMONY GH180 is the most efficient Medium Voltage drive on the market today. The cell-based design features an integrated transformer and has the ability to scale a drive for a wide range of output power and voltage. With increased availability due to its modular design, the drive is able to bypass any one cell during operation. The quality of the output voltage is comparable to none. The practically perfect sine-wave shape allows any other type of motor to be operated with ease.

Replacing DC Motor/Drive with AC Motor/Drive

Posted by Dave Gazda on Sep 29, 2016 1:08:00 PM

Utilizing new drive technology has enabled more applications for AC machines where DC machines have typically been used. In the past, DC machines have been implemented for their good torque characteristics throughout a variable speed range. However, some of these older DC drive systems are becoming obsolete and availability of replacement parts is becoming a concern. This sort of scenario will often be accompanied by a consideration for a drive retrofit project. This article covers some key points and comparisons between the two different technologies that may help make that decision a bit easier.

3 Simple Ways to Troubleshoot Your VFD

Posted by Michelle Szemanski on May 31, 2016 9:19:12 AM

You can feel productivity leeching away as soon as it happens, sometimes even moments before your hear an alarm — the line goes down. Under pressure to minimize downtime, you trace the interruption to a variable frequency drive (VFD). These basic tips can help you walk through troubleshooting a variable frequency drive before you get on the phone with the manufacturer.

Reducing Drive Complexity

Posted by Dave Gazda on Sep 28, 2015 11:16:37 AM

As variable frequency becomes a larger requirement in systems, variable frequency drives (VFD) are becoming very common in the industrial control market. On smaller systems and lower power range systems, the VFD may be too powerful for the application. A complex high feature drive can cause long installation processes and cumbersome commissioning, as these drives typically have a broad number of parameters. Many applications are basic—simple fans, small motors, conveyors, or pumps. Fortunately, you can reduce drive complexity for simple applications that do not require advanced parameter settings and achieve basic and simple installation and commissioning.

Trend Toward Integrated Safety in AC Drives

Posted by Dave Gazda on Jul 29, 2015 10:19:00 AM

Over the past years, manufacturing processes have increased in complexity and the move toward modularity of machines has caused the safety functions to move away from the classical centralized safety designs (for example, deactivation of the complete machine using a main switch) and into the machine control system and/or the integrated AC drives.
