Drives & controllers
Due to significant developments in the field of drives & controllers in recent years, the number of variations and functionalities of drives and controllers has increased enormously. As a result, making a selection is not always easy or straightforward.
Finding the best servo drive and controller for a motion control application
When selecting the right drive and controller for a motion control application, many aspects come into play. Not only the correct motor compatibility but also the requirements of the overarching application and the environment in which it must operate are equally important. Lastly, the price is, of course, also important in the selection process.

Compatibility of the servo drive with the chosen motor
To find a drive that is compatible with the chosen motor, it is necessary to look beyond just the required motor current and motor voltage. The required motor commutation and selection of a motor feedback system are also important. A drive is not always compatible with every feedback protocol. Each protocol has its own advantages and disadvantages. It is important to timely consider which protocol best fits the needs of the application and accordingly select the right type of drive and motor feedback.
The best servo drive for an application
In the application field, other factors are important. A mobile application often requires a drive with a very compact form factor, capable of operating with high efficiency at a low DC battery voltage. This is in contrast to traditional panel drives with a fixed line voltage. When a drive or controller requires a connection to an overarching control system, there are multiple communication protocol options to choose from. Here too, not every drive comes standard with every communication protocol, and it is important to carefully consider which protocol best fits the application and which Drive or Controller is best suited for it.

The importance of the environment of the servo drive - conditioned environment or harsh environment
It is also important to consider the environment in which the drive or controller must operate. Standard drives are often only suitable for conditioned spaces. When conditions are different, there are also drives and controllers for harsh-environment applications, such as in aerospace or deep-sea applications. These are resistant to high temperature, pressure, vibrations, or humidity. It is important to ensure that the respective drive or controller has the appropriate certification or approval required for such conditions.
The role of functional safety
Functional safety is also a frequently seen application requirement nowadays, within the integration of a Drive or Controller in the application. Whether a drive has this functionality and to what level of safety category it is certified is important to ultimately achieve a safe machine.

The development process, the development environment, and the commissioning of the servo drive and application
Lastly, there are aspects related to the development environment and commissioning of drives and controllers. Standard assembled drives and controllers that can be quickly made operational independently through quick-setup and auto-tuning, to complex systems with individual parameter mapping, and the design of custom control algorithms and programming code in a drive or controller under the guidance of full custom engineering, are among the possibilities.
