Acceptable vs. Unacceptable OscillationsWhen tuning a servo, you will be forced to make judgment calls on the servo's performance. To determine whether or not a servo has satisfactory performance, you will need to decipher when a servo has acceptable or unacceptable oscillations. Here are some common criteria guidelines that should be considered when evaluating a servo's performance:
It is important to set your requirements and guidelines BEFORE you start to tune your machine in order to avoid the risk of making compromising judgments later in the tuning process. If clear guidelines are set, it will be easier to determine what is considered a passing or failing performance.
ExampleHere is an example of a servo performance specification.
How do I choose my own spec?See Choosing Specifications for a Machine for more information.
