When To Use Vfd Auto Tuning
Motor parameter autotuning is required when using sensorless vector mode. (P00.00 = 0 or 1) Autotuning is set via P00.15 0: No operation. 1: Rotating autotuning Comprehensive motor parameter autotune. It is recommended to use rotating autotuning when high control accuracy is needed. May 23, 2015 Auto tuning VFD’s Auto-tunes are generally to be performed when the motor is cold. Auto-tuning with a hot motor may result in a variance in impedance which will subsequently cause. When multiple motors are connected, an auto-tune will result in the reading of.
Jul 17, 2016 Now PID control is integrated into variable frequency drive control. For example, if you want to stabilize the speed at 1500rpm, no matter load changed, via an advanced VFD, PID is itself tuning to keep it stable at 1500rpm. I like the auto tuning function on rotating equipment that has high inertia. Apr 16, 2010 The VFD has (3) different tuning tests that it runs with each one as described. The first test is called a static tune and is a non-rotational tune used to calculate the IR voltage drop in the motor (I'm assuming the stator) as well as the leakage inductane IX voltage drop. This video will cover the advanced start and restart control options in the Lenze AC Tech SMVector Variable Frequency Drive (VFD). This particular drive is capable of auto restarting after a fault occurs or even automatically start on powerup. These two options are easily programmable and configurable. The reason behind that glitch was Auto-Tune, a pitch-correcting software designed to smooth out any off-key notes in a singer's vocal track. Released only the year before 'Believe,' it was the recording industry's favorite dirty secret: With only a few clicks of a mouse, Auto-Tune could turn even the most cringe-worthy singer into a pop virtuoso. For motors controlled by a variable frequency drive (VFD), the control method used in large part determines a motor’s efficiency and performance in an application.
If you switched on the radio in the summer of 1998, chances are you got a taste of Cher's 'Believe,' an up-tempo ode to bouncing back after a rough breakup. More than a quarter century after first rising to prominence as a 1960s folk artist, the 52-year-old Cher was once again climbing the charts. Presonus studio one 4.5 waveform. In malls, dance clubs and laser bowling alleys across the country, 'Believe' played frequently. By the time the dust had settled, the song had become Cher's bestselling recording ever -- and one of the bestselling singles of all time.
At the time, the most notable feature of the song was an electronic modification on the vocals. The effect first appears 35 seconds into the song, while Cher sings 'I can't break through.' On each of the last three words, Cher's voice undergoes a bizarre electronic glitch. Duduk vst crack.

The reason behind that glitch was Auto-Tune, a pitch-correcting software designed to smooth out any off-key notes in a singer's vocal track. Released only the year before 'Believe,' it was the recording industry's favorite dirty secret: With only a few clicks of a mouse, Auto-Tune could turn even the most cringe-worthy singer into a pop virtuoso. But most music studios kept it around simply to fix with the occasional wrong note.
During the recording sessions for 'Believe,' however, Cher's British producers had put the software into overdrive. Instead of lightly tuning the pitch of Cher's voice, they had adjusted the levels so sharply that it became an unmistakable part of the song. The effect was weird and robotic, but against a background of synthesizers and high-energy percussion, it worked like a charm. Opera singers have long been using vibrato, a technique of delivering a note in a constantly wavering pitch. As far as Cher and her producers were concerned, though, Auto-Tune was simply a computerized twist on the technique.
As 'Believe' hit the airwaves, the producers aimed to keep the lid on their new toy. So much so, that when interviewed about the technique by a sound engineering magazine, they lied and said it was due to a vocoder, a well-known voice modulation device used since the 1970s [source: Sillitoe].

But the truth eventually trickled out, and when it did, Auto-Tune's inventor, Harold 'Andy' Hildebrand, was shocked. Auto-Tune was supposed to be a behind-the-scenes trick for the recording studio. The New Yorker had compared it to blotting out the red-eye in a photograph, and Hildebrand himself compared it to wearing makeup [source: Frere-Jones, NOVA].

But now, Hildebrand's brainchild was making Cher sound like a robot. 'I never figured anyone in their right mind would want to do that,' Hildebrand told Time magazine [source: Tyrangiel] Whether he realized it at the time or not, Hildebrand's electronic creation was about to become one of the largest technological influences on popular music since Les Paul invented the modern electric guitar.
