What is a servo -ohon?

Servo drive is a device used to provide a wide range of remote, automatic switching or control on the basis of feedback signals from the system on which it is used. In contrast, conventional action drives produce a set, the final work movement in response to one trigger input. The gentle level of control possible by means of a servo drive is made possible by inclusion of the seror controller capable of constantly comparing the desired results with real -time system conditions and calculating the difference, if any, between them. If the differences are scanned, the driver is activated by the driver to achieve the desired result. Service drives are used in a wide range of remotely controlled or automated systems that range from small systems to focus optical cars to large automated maritime arms targeting systems.

Basic control theory revolves around the endPTU remotely to provide an impulse or movement that is necessary to perform the task. It can be a simple back movement and forward to activate the switch or extremely complex, multi -stage rotary movement used to focus a set of lenses. The range and strength of control may also not be more than a fraction of the thumb and a few ounces of pressure on several feet and thousands of pounds of torque. In the case of conventional controls, the supplied movement is relatively simple and predetermined final direction and range induced by a single external source. Applications that require variable control in response to demanding system requirements require greater control and require a service drive system.

Unlike one trigger input of simple drivers, the power supply provides the output movement in response to what is called feedback inputs. These are signals sent by an activated system that defines the exact state and position of the mechanism in real time. These signals are fed to a servo -comparing data that compares dataIn real time with a set of ideal parameters. These may be remote inputs from other sensors and systems or components of a pre -programmed data block.

For example, if the target system of the naval pistol receives a set of required parameters of the situation consisting of a rotary orientation of 185 ° and the deflection of the barrel depression 52 ° from the targeting system, exceeding these parameters against position signals in real time on the tower. If these two differ, the error status is recorded by a controller that directs rotary and height controls to turn the turret and move the barrel of the weapon up or down. When the required conditions are met, the state of the error is canceled and the tower is locked in the readiness of the signal shooting. It is a somewhat simplistic explanation of a very complex system, but is a fair indicator of how the servo controller works based on the comparison of the required and existing conditions. SERVO drive is widely used in many applications, from strong installations such as a turret of nAmařní weapons to very fine examples of light service in automatic lens focus systems.
