What are PCB Mount Servo Drives? Top 6 Benefits

Imagine being able to achieve the same amount of power output and performance from your servo powered device, at a fraction of the cost. Just as PC manufacturers have created smaller computer chips each year with faster speeds, so too has the printed circuit board (PCB) mounted servo drive been able to offer the same performance as panel mount servo drives at a fraction of the cost and size.

printed circuit board (PCB) mounted servo driveTraditionally, panel mount servo drives were housed in metal cases and installed into electrical panels which took up lots of space in the machine. Embedded servo drives greatly reduce the space required to operate by plugging directly into your PCB and eliminating the need for metal housing and connectors. PCB mounted servo drives can either be constructed using detachable connections or soldering.

More often than not, PCB mount servo drives are connected using plug-in style connectors, however soldering the connectors can be beneficial for extreme conditions to increase the reliability of the electrical connections. You’ll often find PCB mount servo drives used in 3D printing, CNC machining, robotics and other tightly integrated applications.

The space saving capabilities of PCB mount drives allows room for additional components in the machine to make it more functional and capable, or to make the machine smaller and lighter if desired. For this reason, PCB mounted servo drives have become huge in the automation and robotics industries.

PCB mount servo drives offer the same features as panel mount servo drives, including output current, servo performance, network IO capabilities, feature set and more. Here’s a list of the benefits that you can expect from PCB mount servo drives.

Benefits of PCB Mount Servo Drives

1.   More Cost-Effective

pcb mount servo drives benefitsWith reduced wiring and system complexity, PCB mount drives are less expensive yet offer the same performance as their panel mount equivalents. Commissioning and servicing costs are also reduced due to their ease of installation.

2.   Reduced Footprint

pcb servo drives small size big performanceOwed to their simple and space-saving design, PCB mount drives take up a fraction of the volume of panel mount servo drives. A smaller footprint gives designers increased flexibility when they laying out components as well as reduces the overall machine size and weight. PCB mount drives can be mounted closer to the motors in places where a panel mount drive would never fit, such as directly into a robot arm. The lightweight and compact design of PCB mount servos make them perfectly suitable for almost any application that requires tight integration.

3.   Same Performance as Bigger Drives

Even though they’re smaller and less expensive than panel mount drives, PCB mount drives don’t sacrifice on power output and performance. PCB mount drives can output 60A peak and 30A continuous while taking up less than 39 cm^2 of board space! Furthermore, with newer designs the power density can be doubled.

PCB mount drives also have the same current loop bandwidth, current output resolution and servo update rates as their bigger counterparts as well as the same tuning capabilities, feedback resolution capability and positional accuracy.

4.   Easier Integration

multi-axis system pcb servo drives

Many designers choose open designs that allow for quick plug-and-play mounting. For multi-axis systems, PCBs can be designed to accept multiple single-axis drives. PCBs can also be designed to accept mating connectors that are compatible with your motor manufacturer’s standard cables, thus reducing cabling costs and increasing reliability. With a well thought out PCB design it can make it easier to install your PCB mounted drives and connect the controller, feedback, and motors.

5.   Greater Flexibility

Customers who design their own PCBs can place the drives and mating connectors in the locations that work best for them.

6.   Greater Power Density

Power Density is defined as how much power the servo drive can output divided by how much volume the servo drive occupies (Power Density = P/V). PCB mount servo drives have some of the highest power densities available and they are getting even smaller and more powerful. The limiting factors for power density are heat dissipation and connectorization. Improved power devices can operate more efficiently which allows them to produce less heat while the plug-in style connectors greatly reduce the amount of area that traditional connectors would take up.

Why Select PCB Mount Servo Drives For Your Next Project?

digital pcb servo drives costs and benefitsPCB mounted servos offer much of the same characteristics as panel mount servos at nearly half of the price and size. Don’t think that this limits their ability to work as well as panel mount products. Whether you’re working with a brushed or brushless motor, we have standard PCB servo models that will operate with your motor.

Choose from analog PCB mount servo drives with simple configuration or digital PCB mounts with the same performance as a panel mount servo. With a cost effective price and comparable performance, making the switch to a digital PCB mount servo drive seems well worth the investment.

New Webinar. Servo Solutions For Mobile Automation Challenges

Live Webinar Tuesday April 21, 2015 11:00am EST, presented by Advanced Motion Controls & Electromate

With automation expanding out of the factory, machine builders are faced with a varying set of new challenges.  Mobile platforms, such as unmanned systems, are expected to operate in extreme environments and carry their own power source; all while being light weight and compact.

To meet the current and future needs of the market, enabling technologies need to be applied and discovered.  At the forefront of the enabling technologies are servo drive controllers.

Servo controllers not only make a robot or mobile platform move, they can also be solutions to the other design requirements.  A servo is an integral component to any mobile solution and can help with power efficiency, communication, agility and dexterity.  This webinar will touch on the challenges presented to robot designers and how servo drives can make them successful.

Power Supply Selection for Servo Amplifiers

White Paper reprint: by Rene Ymzon, Advanced Motion Controls

 

There are several factors to consider when selecting a power supply for servo amplifiers.

1. Power requirements

2. Isolation

3. Regeneration

4. Voltage ripple

Power requirements refers to how much voltage and current will be required by the amplifier(s) in the system.  Isolation refers to whether the power supply needs an isolation transformer.  Regeneration is the energy the power supply needs to absorb during deceleration.  Voltage ripple is the voltage fluctuation inherent in unregulated supplies.

Each consideration is discussed in detail in the following pages [click on the link below…]

New motion control system options utilizing EtherCAT® technology

A New White Paper by Advanced Motion Controls

Servo-based motion control systems have traditionally been categorized into two types: centralized or distributed.  Centralized systems use dedicated motion control cards that account for all aspects of the system including servo commands, motor feedback and I/O to close all control loops while simultaneously running complex programs that plan motion profiles and maintain machine operations.  Increasing the number of axes involved places an ever increasing burden on the processing power of the DSP quickly making the system unmanageable simply due to scalability.

AMC's EtherCAT Servo Drive Family

AMC’s EtherCAT Servo Drive Family

In distributed systems, motion commands are less complicated since the drives close the velocity and/or position loops internally leaving the controller to focus on motion profiling, planning and associated I/O. However, limitations arise as communications speed may be the limiter of some specific motion and machine requirements.  Even though systems can be made to be deterministic, the ability to keep up with demand can also be a challenge, even for simple machine tools…
