Why Servo Drives are Beneficial for Motion Control Applications?

Posted on 3rd Oct 2022

Robotics, warehouse automation, CNC machines, and other automated control systems all use servomechanisms. In motion applications, closed loop systems with servo drives offer more precision and dependability than open loop systems.

They use feedback to account for errors and system disturbances as opposed to open loop systems. The servo motor in a servo system is powered by a servo drive or servo amplifier. The servo drive plays a crucial part to determine how well the servo system works.

Servo drives provide a number of benefits for automatic machining systems over straight power amplifiers, including greater positioning, speed, and motion control. For your unique application, we at Darwin Motion – VFD & Servo Drive manufacturer provide a comprehensive selection of servo drives.

Servo System Diagnostics

Let's talk about the function of servo drives in servo systems so you may comprehend them better.

All servo systems need four essential parts for functioning such as Servo drive or servo amplifier, controller, motor, & feedback apparatus.

Analog or digital inputs are both capable of controlling servo drives. Essentially, the servo drive's job is to convert low power controller command signals into high power motor voltage and current.

The servo drive can regulate and correctly coordinate the motor's desired position, speed, torque, etc. depending on the application.

Through a feedback monitoring device that uses negative feedback to send a signal back through its own control loop and/or to the main controller, servo drives are able to take into account expected mistakes. The feedback device in motion control assesses the relationship between the control input and the actual position of the mechanism or control shaft.

Digital servo drive by Darwin Motion, to put it more precisely, the servo drive is in charge of managing the discrepancy between the requested and real motor statuses by adjusting the current or voltage as needed.

This contrasts with an open loop system where the motor could always spin at the incorrect RPM. The motor can respond with damping, feedback gain, and stiffness depending on the needs of the system thanks to servo drives.

This makes servo drives the ideal choice for automatic systems that require position control. Whether it's only adjusting a globe valve's position or guiding a telescope, a servo drive can steer a shaft to its intended position regardless of friction or other disturbances.

Applications for Motion

Robotics, automation, CNC machining, and the production of semiconductors all require servo drives. Servo drives are employed in robotics, automation, CNC machining, and even the production of semiconductors because of their precision-related capabilities.

Utilizing tried-and-true technology, analogue servo drives are used in several motion control applications. Analog drives don't need any processing time and are often less expensive than digital counterparts, despite the fact that they might not have as many bells and whistles as many contemporary digital drives.

Analogue servo drives require manual configuration and rely on a centralised controller in multi-axis applications. Servo controllers can interface with digital servo drives via network commands in other multi-axis applications.

Over pneumatic or analogue systems, digital servo drives offer far more configuration and performance options. Modern servo drives offer much higher diagnostic advantages thanks to the enhanced intelligence of these devices.

Some modern digital servo drives can even use input/output logic to function autonomously without a separate controller by storing motion indexes and sequences in their memory. For motion control, fieldbus networks, which have become standardised, are currently used by the majority of the industry.

Industrial Ethernet networks have made it possible for manufacturers to work in time-critical applications.

Each network has advantages; however, some items are made expressly for various fieldbus networks. If your institution has adopted a particular network protocol, it is crucial to get the right device.
