In the world of industries, there’s are many terms an outsider doesn’t understand. One of them is the variable frequency drive. What is it exactly? Most of us never heard the term before, so let’s clear it up a bit. The variable frequency drive is a drive that can adjust the speed in any electromechanical drive systems. It’s used for controlling the AC motor torque and speed, and it does this by having variations in the frequency and voltage.
About the Siemens VFD manual
The range of application in which they are used ranges from small, everyday appliances up to mine mill drives, but the actual market penetration remains of small scope still. The centrifugal fan, pump and compressor with fixed speed still covers more than one third of the world’s market. Even if the market coverage remains small, it’s growing from day to day. Over the last forty years, the VFDs have become smaller and have improved greatly performance wise. This was possible due to many advances of semiconductor devices, simulation techniques as well as control techniques and in hardware and software. The Siemens variable frequency drive has very good quality. It uses the low harmonics technology that is utilized through its low harmonic design, making the DC link chockes a part of the past. If something goes wrong, there’s the EasyComm option, making it possible to perform quick troubleshooting and commissioning. Should there be some issues you are unable to solve on your own, you should look them up in the Siemens VFD manual. Make sure to check out the manual before attempting to do anything on your own. Read everything first, and then proceed to actual work. Download your manual here.
