What is servo tuning?
FAQ about PMC Motion ControllersA servo is a type of closed-loop feedback circuit. A servo motor works by comparing the motor's actual position (as read from a feedback device - usually a position encoder) to the desired position (as calculated by the motion controller) and by dynamically adjusting the motion controller's command output signal so as to try to minimize the difference (error) between the two.
Related QuestionsHow can I optimize the tuning on a Pacific Scientific digital servo drive?
Pacific Scientific | about us | company | corporate | info |...To optimize tuning for a system that is oscillating. Start by setting ENABLE=0, ARF0=1000, ARF1=1000, KVI=0, KPP=0, KVFF=100, KVP=0.01. The motor should be quiet and without vibration. CAUTION! Do not perform this operation on a vertical application. The load will drop to the ground. Change ENABLE=1. Slowly increase KVP by 0.02 increments, pausing 1.0 sec between changes until the motor oscillates. Disable the drive with the hardware enable\ input. Reduce ARF0=400 and ARF1=400. Enable the drive.

Related QuestionsWhat is tuning?
FAQ's The PianoTuning is the process by which the piano is brought into sonic regulation with itself. The process of tuning is a multi-stage process. The tuner begins by setting the instrument to the pitch to which it is to be tuned. He then performs the setting of the "temperament." This is the 12-note pattern that governs the entire tuning of the piano. It is based on a mathematical formula that dictates that all the notes in this 12 note pattern be spaced equally apart in distance from each other.
Related QuestionsPiano Expectations - Frequently Asked QuestionsEach of the 88 notes on a piano has one, two or three strings. (Some pianos have more or fewer than 88 notes.) Over time, the piano will go out of tune due to changes in relative humidity. Changes in humidity expand and contract the wood of the piano, thereby altering the tension of the strings which affects the pitch of each string. In addition to changes in humidity, piano strings stretch with time, causing the piano to drop in pitch.Related Questions
What exactly is the Buzz Feiten tuning system?
Frequently Asked QuestionsIn short... moving the nut about a millimeter closer to the first fret. You were expecting a long technical answer weren't you? Now you know why they try to keep everything about it a secret... but wait, there is more! Once this modification is done, you must use a special electronic tuner that has built in Buzz Feiten offsets to tune your guitar. You'll also have to learn a new method of string to string tuning for when you don't have your "special" tuner handy.
Related QuestionsChiptuning, Performance Tuning and Remapping Frequently Aske...All RICA ECU upgrades for petrol cars are optimised for use with 98 RON super unleaded for maximum performance. For diesel engines, a high quality diesel fuel such as BP Ultimate or Shell V-Power is recommended. Using low octane premium unleaded fuel will not allow your engine to achieve its maximum potential from the Chiptuning and may in extreme cases result in engine damage under high load conditions. If you must use low octane fuel, you must not drive the car hard.Related Questions

Naturally chord shapes are a little different but alternative tuning can open a whole range of possibilities for both the fingerstyle acoustic and electric guitar player. One of the simplest is known as the dropped D tuning. In this tuning, the bass E string is simply detuned down a tone to D.
Related QuestionsIt is confusing that there are so many different ways of tuning it up. What should I do?
FAQThis is, of course, up to you. You need to decide what you want your bike to do. If on the track, go for full on jet kits. If on the street, maybe simpler measures might be worthwhile. Fit 3/1 Micron/Sebring/Staintune all are expensive, but the sound and improved accelleration is worth it. The jury's still out: only beneficial if your fuel is crap and needs more burn time (see Jim Bazz' experience on his Daytona 1200. He is not very big on the timing rotor at all.)
Related QuestionsWhat further tuning is possible?
Chiptuning, Performance Tuning and Remapping Frequently Aske...Chiptuning is often refered to as 'stage 1' tuning. However, further tuning is always possible. The sky is the limit and depends largely on your budget, but it is not always economically viable for every car. More power costs more money, and the cost of tuning often increases exponentially when trying to extract more power, so essentially the higher the level of tuning, the lower the value for money for the power you actually get, especially when compared to software tuning alone.

Related QuestionsMy Servo can move wider angle than I expected, why is that?
FAQTXServo unit can product signal pulses from 250usec (microsecond) to 3500usec easily due to electronics working at 24Mhz. Most of the time, you shall see specification of 1.0 ms or 1000usec to 2.0ms or 2000usec. Testing with TXServo can show the real capabilities of your Servos because it can produce a wider range of signal to test your Servos.

Related QuestionsWhat is the difference between stepper and servo?
FlashCut CNC - Windows CNC Software and CNC ControlsStepper motor control is the most cost-effective way to control a machine tool. The accuracy is exceptional, and the price is very reasonable. The only limitation is that the maximum speeds for rapid moves and cutting moves are not as high as for servo control. Servo control uses feedback from an encoder to constantly monitor the machine tool_s exact position. Using the feedback signals, the control system can achieve very high speeds and perfect accuracy, even under very strenuous conditions.
Related QuestionsQuestion: What signals go from a receiver to a servo?
Model Airplane FAQThe servos are supposed to get a block-shaped pulse with a fixed frequency, with the duty cycle varying to control the position. A 1-2ms pulse every 20ms (which corresponds to 50 Hz) will give you full travel, with 1.5ms being in the center, 1ms at one extreme and 2ms at the other.
Related QuestionsQuestion: How can I reverse my servo?
Model Airplane FAQYou can reverse a servo quite easily, if you have expertise in soldering. Use a small iron, maybe 15-20 watts with a very fine point, and use rosin core solder only. Get help from someone who has experience. Open the servo and reverse the 2 wires going to the motor. If the motor is connected directly to the PC board, close the servo up and buy a reverser. You also have to swap the 2 outside wired on the potentiometer, which is WAAAAY down inside the servo case.
