The most important components of a variable speed drive (VSD) come in two major sections. The power stage and the control circuit. Within the power stage component of a VSD, the first element is the internal connection to it. It enables the control device to tell the power what and when to provide output to the electric motor.
When it comes to the control circuit, there are two elements - the analog and digital inputs and outputs that are simple to use. Depending on the specific variable speed drive unit, the number of inputs and outputs vary. But all of them can be programmed to perform a variety of different controls and functions. Take for instance the case with an analog input that accepts up to 10v signal. It can control the speed as well as the digital output sending a higher 24v signal to the drive. With this, the VSD can then utilize logic to work with the entire machine to provide sufficient control of the whole operation.
If your application requires more advanced controls, there are control circuits that are equipped with modular operations. A variable speed drive that has this element can be used for real-time control and communication operations. Overall, both major components of the VSD, the power stage and control circuit, work together to achieve the desired results of the operation. Each of them needs a different set of controls and features to work efficiently.
