About Servo Control Drive

To begin with, we have to first understand the concept of 'servo'. What does it do and how does it function? In simple words servo may be defined as an automated instrument that controls the performance of any machine based on the continuous feedback. It functions in a closed loop—feedback, rectification and performance. So a servo control drive monitors the performance of a servo drive. It is an electronic amplifier that connects itself to the servo mechanism to monitor its performance.

 How does a servo control drive function or how does it monitor the performance? It basically receives signals in the form of commands from the servo control system, amplifies it and then transmits the right amount of electric current to the servo motor to achieve the desired benefit. The sensors that are attached to the servo motor are responsible for feeding the actual performance data to the drive. Later, the actual data is compared to the desired data, the deviation noted and then rectification is done by transmitting the changed voltage frequency to the servo motor.

 Different types of servo control drive are available in the market. Here is a list of the most common types used by the industries:

 Normal servo drive are usually used for applications consuming less power.

• Digital servo drives are a bit complicated and are programmed to handle multiple applications.
• Multiple axis servo drives allow more flexibility to the machines as they are designed to handle higher voltage needs.
• Ethernet servo drives help in standardizing the entire communication network in turn leading to faster commissioning and more accurate configuration.

 Servo control drives are widely used because of the many advantages or benefits. Implementing servo control drives reduces human intervention in machine usage and thereby increasing manpower productivity. It reduces errors and its effects and is more cost effective and improved productivity. This also increases flexibility that can be mapped across diverse types of machines. It also facilitates accurate output.

 

The servo control drives are much superior to the traditional AC or DC motors. The motor feedback feature is used to identify and unwanted disturbance thereby rectifying it and increasing accuracy. Servo drives are even known to have a longer life span than the old AC wound motors.

 

Industries like CNC machining, robotics and factory automation use servo control drives to reduce transient response times, lessen the sensitivity to load parameters, reduce the steady state of errors thus facilitating increased machine accuracy machine throughput.

Digitally Operating Motion Control Drives

Motion Control drives have one of the most varied applications in the form of digital brushed and brushless servo drives. These drives can be availed in stand alone formats, PCB or panel mounted formats with a choice of bus protocols or simply with control inputs for step and direction and also analogue inputs. With high energy efficient features that pertain to output powers much less than 100W and inclusive of up to 110Kw output. The motion control drives are capable of meeting varied applications that demand, torque loop, speed loop or position loop formats. The drives are completely digital and can work in both current as well as speed and position loops. If we measure their efficiency with respect to size to output power format then the motion control drives will stand out as one of the best in the industry. These drives can be availed with a range of servo motors as per the customers need and requirements with respect to power, size and drive packages. As per client demand, the drives can not only be provided with on-board independent controllers but also with multi axis controllers of the range of Motion Controls.

 Main Features of the digital Motion control drives:

 The digital Brushed motion control drives from 20W up to 400 Watts. It is capable of taking step and direction or analogue to +/-10V inputs

The digital Brushless motion control servo drives from 40W up to 110kW. It can take either step or direction at +/-10V analogue input.

The drives can work with either DC or AC generation, in a single or three phase even.

They are Ultra Rugged and Compact. These features make them sustainable even in rough manufacturing conditions while ensuring that they do not pose space constrains.

The digital motion control drives produce higher efficiency output ranges and are therefore a little costlier than the other control drives. The fully built-in protection adds value to the buyer's money as these drives require minimum maintenance.

The motion control drives are digitally set to comply with ruggedized options in extreme environments.

The application areas of the digital motion control drive includes in food and material processing industry, packaging industry, Printing equipment, material handling, film & foil converting, Industrial automation, textile etc. Modern manufacturing industries are slowly getting inclined towards the application of digital motion control drives. The reasons are many, some of which have been discussed above.
