There are some specific sorts of a controller, which are mainly designed to control servomotor. This controller is known by the name of the servo system controller. You need to keep one thing in your mind the true definition of the servo system, servo motor and servo controller varies a lot in the industries. The moment you plan to select a servo system for an application then the next thing, which you need to do, is to ask your suppliers about the things that they are offering.
One cannot deny the fact that the servo controller is the main heart of the servo system. Moreover, if you talk about a servo system and have a desire to purchase one then you will find that it consists of a feedback device, motor and also a controller.
Mentioned below are some of the points that you need to consider at the time of selecting a servo controller for any system.
- One of the main questions that you need to ask yourself is what type of motor do you plan to control. This means that whether it is a servo motor or an AC or DC motor. The reason behind know all these specific details is that you understand the kind of commutation that the particular motor need. And also whether the controller is in a position to accommodate it.
- The next thing, which you must know, is the axes of motion that the application has. That is whether the application is a single axis of control or they are having multiple axes. You must not forget that the servo controller is mainly available to control the simple single-axis application and also robotics application which uses multiple axes.
- Another important thing to determine is the number of I/O channels that are required. You need to ensure that the controller can easily accommodate the feedback device such as the hall sensor signal, resolver signal and etc.
Apart from all this, the setup of the servo controller is something that cannot be overlooked. You also need to determine whether the controller is easy to program or not. Moreover, you must also know whether the programming, which needs to be done to the system controller, is executed with the help of a keypad or with the help of a computer screen. At last, you must also consider all the available communication links to the controller.
