What are the different types of drive controls?
drive controls are mechanisms used to start, stop and protect drives from overload and excess cycle. Drives can be controlled by two basic methods-simple manual or automated stop/start systems or more sophisticated multifunctional actuators. The drives that are used to fulfill simple individual functional roles usually use a simple STOP/START control system. Those who are used to constantly produce a wide range of activation movement in response to complex installation requirements will generally be part of the servoving system. However, most of them also include sensors that prevent an excessive cycle or driver running if the mechanism is stuck or damaged.
A large number of all mechanical processes include some or other type of driver. These devices supply remote switching or activation of secondary processes where the operator's intervention is not practical. Although the driver is able to perform PRThe human operator must either manually or automatically run and somehow stopped. This is the function of the controls of the controls that not only activate and stop the device, but also protect against potential damage caused by excessive cyan and overload. These controls can consist of very simple stop and start function or complex control functions.
In general, action members that create simple functions such as switching the machine on and off will not require more than the same simple control system on and off. These drive controls can be controlled manually by the operator in the control room by pressing the stop or start button or being part of an automated system. Automated drivers usually consist of an external sensor, such as a level switch that triggers and stops the driver. A good example is a complementaryAating valve on the water tank. When the water level drops below the set point, the level switch begins with the controller connected to the refilling valve, allowing the water to flow to the tank to the point where the level switch is reactivated and the valve is turned off again.
Comprehensive systems requiring constant setting of system parameters in real time require controls of drivers capable of more flexible outputs. In these cases, a servo system that responds to the system requirements is usually used. This is achieved by means of inputs of the system feedback that gives the controller information about its status in real time. It then evaluates the information and activates the drive to compensate for process needs. The controls of the simpler and servo, as well as the servo, will usually include the sensors connected to prevent excessive cycle or work over its limits and continue running if the mechanism is stuck or damaged.
