A quick-paced modern factory environment requires equally intelligent and high-tech equipment to track, monitor, and control various automated tasks. Because of this, Siemens has developed a series of converters - SINAMICS G120 and S120 - to handle more complex applications. Below, we’ll walk through the specific functionality and uses of these devices as well as the additional safety features built-in to maintain factory security. While we’ll be discussing these specific converters, it is important to understand that the same functionality can be found across a wide range of industrial converters, so don’t worry if you’re not specifically using a Siemens device.
Understanding the distinction between AC and DC drives and their roles in the regulation of speed and power in electric motors can be critical to helping your business. Simply put, a drive is a device that is used to control the speed of an electric motor by altering the frequency of the electrical supply to the motor. AC and DC drives perform this action in markedly different ways and to differing effects. Below, we’ll discuss the distinctions between the two types of drives and help you determine which drive - whether AC or DC - would be best suited for your application.
The 2019 Engineers' Choice Grand Award-winning Siemens SINAMICS G120 Smart Access Module is a must-have accessory for interfacing with SINAMICS G120 variable frequency drives. Using any mobile device, users can securely connect to the G120 WiFi server then have the ability to commission a G120 drive, edit parameters, run in HAND mode, and more. The web server functionality eliminates the need to download additional software.
Over the years, drive technology has truly advanced and gotten more diversified, giving users a wide variety to choose from. Low voltage VFDs have made their way to applications of up to 2500 HP, and greater, while medium voltage VFDs are being used for applications as low as 150 HP. A 2016 industrial survey revealed that customers were considering making the shift from LV to MV VFD solutions.
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.
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.
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.
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.
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.
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.
