Electronic assembly of printed circuit board

Here you can see the example of the process of drilling a printed circuit board (PCB) by a spindle CNC Drill Machine.

This is a step of PCB electronic assembly process.

Products that Servotronix provides include off-the-shelf products, custom servo drives for placement head mechanisms, and fully-custom drive systems for overall machine control.

Custom Servo drives - an Overview

Custom servo drives are a kind of cost effective and optimized servo drive which are designed according to the customers applications to meet their needs of form, cost, fit and function specifications. Mostly known as the “special electronic amplifiers”, a custom or standard servo drive is commonly used to control the motors of the electric servo.

Over the decades, the technology of servo controls has changed a lot with its size, rotational speed, and torque. Custom servo drives are one of the major developments in the world of servo drives. The custom servo is almost similar to its digital counterparts. They have the same gears, motors and cases and most importantly they have a “Feedback potentiometer or Pot” like the digitals.

Designs of the custom servo drives:

• Optimized packaging- form factors, special connectors
• Multi Axis- two and three axis packages and systems based on racks
• Power Ratings-voltage and custom current ratings
• Java Beans-“fill in the blanks” standard indexer functions
• Enhanced Firmware-standard compensation filters
• Performance Edge-temperature compensation, low noise
• Feedback-special encoders

Classification of custom servo drives:

Custom servo drives can be classified based on the shapes, electric circuitry, sizes, type of feedback, input power variations, command and performance signal. Every factor has a great value in making the decision of the actual price of the custom servo drive.

Usage of custom servo drives:

Nowadays, custom servo drives are usually used in various industries like packaging, robotics, textile, factories of CNC machining and printing. With the increasing usage, the need of custom servo controls has increased a lot.

Advantages of using custom servo drives:

• Power saving ability:  In a custom servo drive, no power is sent to the servo motor when the car is idle. When the signal of moving the car is received, the power is sent to the servo motor up to a maximum voltage and then the servo responses. The servo doesn’t responses until the power reaches the maximum. This helps to save the excess power from being wasted. 
• Immense Standing Torque: The quotients of the standing torques of the custom servo drives are very high.
•  Monitoring: The custom servo drive is able to monitor the feedback signals from the motors by making some subsequent adjustments.

It is a fact that custom servo drives are very essential for the industry which totally depends on the motion control. So, to grow your industry, switch on to custom servo drives.

Important Facts behind Servo Motion Controller

Servo drives have been an integral part of efficient output ever since they came into being. The servo motion controller has further enhanced the way industries can work, with precision management of position, velocity and movement and therefore aligning the entire process uniformly. 

The key industries benefiting from servo control system include:

• Assembly line units
• Industrial Machines
• Packaging industries
• Semiconductor production facilities
• Textile mills
• Printing houses
• High end video game industries
• Robot manufacturing
• Medical Equipments

The various servo drive products range from the simple servo motors, DC motors, servo drives, gears, linear motion components and actuators, linear ball and lead screws, linear and rotary brushless servo motors among others. The servo motion controller enhances velocity and position of these machines and their electric motors for effective and efficient output. 

The wires in servo motion control:  The 3 wire connector –

1. One supplies five to six volts of positive charge (DC)
2. The second one serves as voltage ground
3. The third wire acts as the signal wire through which the receiver responds

Servo motion controller not only enhances machine performance but also anticipates mishaps. The in-built mechanism can read slightest of the errors thus acting as a checkpoint for your machine’s efficiency. 

Benefits of servo motion control –

•             Accelerate system development

•             Increase system bandwidth

•             Control velocity, forces and pressures

•             Monitor feedback signals

•             Adjust motion to avoid deviations

•             Managing point-to-point positions

•             Quicker response times leading to higher machine output

•             Electronic gearing

•             Address mechanical needs of improving the transient response timings

•             Reduce steady-state errors

•             Diminish loading parameters sensitivity

•             Decrease voltage fluctuations.

•             True asset utilization

•             Lower total production costs

The most commonly referred role of the servo drive is that of the mediator. The control system sends specific signals to the drive which they amplify from their end. Then they transmit the current to the motor to create and incite a motion and torque that is in sync with the original signal, thereby brining in a balance of power and output in the device. This improves performance by adjusting and anticipating change. 

The key functions of the servo motion controller include command tracking and addressing all disturbance rejection traits that lie in the system. Together they track, mange and streamline processes. It includes the drive or the amplifier, motion controller, sensors for tracking feedback along with a hydraulic pump or air cylinder acting as a linear actuator.
