 Factory Automation and Machine-to-Machine (M2M) Advances

As technology evolves, automation has become more and more prevalent in the factory automation space. Machine-to-machine enables private and exclusive communication and control over sensors, cameras, industrial equipment, robotics (check out our FANUC Robotics parts) and essentially anything else. Manufactory facilities and several other remote systems are managed much more easily with machine-to-machine advances in communication.

Initially, with industrial and enterprise applications as a focal point, machine-to-machine communication was easily defined and used for a limited amount of tasks. Nowadays, there are many fewer limitations associated with the machine-to-machine communication.

Pressured to lower costs and improve speed and overall efficiency, factory automation companies are often in an uncomfortable spot. While using high-end, sophisticated automation applications and tools, more real-time data must be obtained to streamline more of the day-to-day operations and tasks. Implementing machine-to-machine solutions can help with operational efficiency gains, time and cost savings, and performance optimization.

From a cellular standpoint, machine-to-machine solutions enable integration of environmental controls into a single system, and to unify with security and video surveillance systems. All and all, companies are able to secure several properties from anywhere they wish to, even as they fine-tune power efficiency and decrease operating expenses.

Due to the immense increase of machine-operated plants in companies who rely on keeping critical assets and functions performing optimally, several companies are exploring options associated with a machine-to-machine communication. Of the many benefits, the fact that it’s able to deliver remote access to gather real-time process data to cut operation costs is often one of the most well-recognized. The ability to identify and rectify production line faults, or design and implement preventative maintenance strategies, for example, is what machine-to-machine communication is designed for.

Involving data exchange over the telephone line or via the internal with machines, plants, computers for issue detection, diagnostics, and repair, teleservice is an imperative aspect of machine-to-machine communication. Offering an optimal answer to diagnose distant systems, teleservice is becoming more and more popular and is not going anywhere.

Telecontrol, another aspect of machine-to-machine communication, deals with connections of distant process stations to one or more central control systems. Many networks, both public and private,  can be used for communication used to control. For these diverse applications and businesses, cellular M2M connectivity can address many business and technical challenges and enable important benefits.

MRO Electric and Supply has new and refurbished FANUC Robotics parts available. We also offer repair pricing. For more information, please call 800-691-8511 or email

Additionally, M2M systems can be designed to withstand harsh environmental conditions and easily manage and control connected devices across the country or around the world. M2M systems provide flexibility to move equipment as needed, or bring up and tear down systems quickly for temporary or seasonal deployments. By using modern M2M management and application platforms, and taking care to choose platforms designed to meet real-world requirements, organizations can take full advantage of the M2M revolution.

In case you were wondering, machine-to-machine systems are indeed designed to withstand environmental conditions and easily control connected devices in any location. They are flexible and can move equipment with ease. In order to use machine-to-machine communication optimally, look into management and application platforms.

Boosting Factory Automation Productivity

In the factory automation space, productivity is much more than an imperative management concept; it is a scalable tool that drives employees and processes to be functioning at their best. In order to keep employees on track and enable goals to be met in the workplace, fine-tuning processes and running a ‘tight ship’ as far as time management is concerned is considered best practice.

As far as work is concerned, understanding where to start is the first, and often, most difficult step. Understand what may set your company back, whether it be a worn down motor (such as a FANUC CNC Motor) not performing up-to-par, or a poorly-maintained Servo Amp (such as a FANUC CNC Servo Amp).  Missing expectations due to a faulty machine is avoidable, as seen in this article focusing on Maintaining Automation Machine Tools.

To ensure your teams’ insights aren’t hindered, consider documenting priority-oriented processes such as customer service, client retention, and cutting operation costs, that way, more focus can be put toward improving workflow, coaching employees and pinpointing other areas that could be improved on. Take industry benchmarks into consideration; they can be used as a point of reference to determine if an area can be improved in, or if it’s already up-to-par. Along with documenting the aforementioned processes, keeping track of progress and growth can also aid in fine-tuning.

In order to remain on the same page with employees, ask for their buy-in and try to understand where they’re coming from. They may help shed light on problematic areas such as why certain departments aren’t working as closely together as they could be, or if downtime could be minimized by having two departments working together more effectively. By making employees feel valued and trusted, a company is less likely to run into honesty issues, communication issues and/or issues with collaboration. The foundation for productive operations starts with an honest, well-communicating team. Teams need to have an in-depth understanding of where they’re expected to add value and, of course, what the company is working toward as a whole. Eliminating clutter in order to have a well-focused and productive team is an achievement that most of those in the factory machine automation space don’t lose sight of. MRO Electric and Supply has new and refurbished FANUC CNC parts available. We also offer repair pricing. For more information, please call 800-691-8511 or email

These days, there are shortcuts and tools for essentially any and every niche. Many of those in the machine and factory automation space are focusing on robotics (see FANUC Robotics parts) to explore ways to automate processes in hope of enhancing productivity. Be sure to stay ‘in the loop’ when it comes to tools that could enhance one’s productivity through collaboration, etc.


Gathering Information Before Considering a Repair

Gathering Information Before Considering a Repair

Downtime is inevitable when it comes to machine automation. When production stops, orders will likely stack up quickly, hitting start on the ‘profits lost’ clock. After the failed part is identified, many machine automation professionals would lean towards shipping the flawed part to get serviced as soon as humanly possible. While MRO Electric and Supply appreciates the business, we want to ensure our customers are as well-informed as possible and able to fix issues of their own, is able to.

By grouping observations together and looking at them closely,  many of those in the machine automation space may find that the issue can be fixed internally, rather than sending a part out to another party. Be sure to press the in-house employees for details, as someone on the clock may have witnessed the failure first-hand and would be able to provide more intimate and valuable insight as far as what may have happened. Any way to avoid a future issue is worth exploring!

As many know, factory automation machines consist of several interconnected parts and components. Because of this, it’s important not to overlook related issues that have occurred or may occur. If a drive (such as a FANUC Robotics Drive)  were to fail, best practice would be to send it along with the motor it’s connected with to preventative maintenance to be checked together. By consulting with the machines’ operators, you may find that other parts could be sent to preventative maintenance along with motor (such as a FANUC CNC motor)  and drive. Keep in mind, certified experts will likely be able to point machine details out that others may not recognize or think of. Nobody wants to run into an issue, fix said issue, and run into it again, due to lack of attention to detail.

Whether you have only two wires to unhook or twelve hundred, document everything. When you uninstall the damaged unit, label your wires. Be sure what you are using is sturdy and will remain affixed. Do not use tape that will slip off with grease or dust. Also, take before, during and after pictures of the operation. These pictures can save you from a tremendous headache later on. Also, when possible, make sure to save any parameters and record any settings before the unit has been taken out of service.

By documenting all of the parts or wires that had to be disassembled as specifically as possible, you would likely be avoiding many headaches. Nobody wants to disassemble a section of a machine, later to discover a wire or bolt is misplaced, which would lead to dreaded downtime that everyone in the factory automation and manufacturing space dispises. Don’t be afraid to take a video or several photos of the disassembling process; in-depth videos or even photos are often invaluable to refer back to, especially when in a rush or a busy time of the year.

In order to make your time count with the service center, be sure to prepare your explanation on a written or typed document. If there’s a possibility of more than one employee communicating with the service center, ensure they’re up-to-speed with all details that may be of help to fixing the issue or issues at hand. MRO Electric and Supply has new and refurbished parts available now, and also offers repair pricing. Be sure to check out our core exchange program to learn how to save. For more information, please call 800-691-8511 or email

Be sure to avoid shipping damage by packing the part or parts securely and appropriately. Nobody wants a quick and painless fix to turn into an extended fix due to laziness or lack of initiative to research correct packaging processes. Most units need 3-5 inches of packaging insulation on all sides, to ensure rough handling won’t damage the part or parts. Check out our other articles focused on robotics here.




Workforce Automation and Robots

FANUC Robotics

Workforce Automation and Robots

Automation has been in mind for not just decades, but centuries. Whether we’re talking about those who worked in flour mills or those who dealt with windmills, automated processes have always been on inventors’ minds. While automation would technically result in job losses, the increased prevalence of robots and robotics parts (FANUC Robotic Parts found here)  in the manufacturing, packaging, and engineering space would result in interesting implications for consumers, employees, companies, organizations, etc.

Does Workforce Automation Result in Job Losses?

Many are convinced that automation will come and take over a majority of the work done by humans in the next few decades, and some feel as though their jobs are safe. Let us take China for example. China is one of the most dominant manufacturing hubs in the world, supplying a huge chunk of the world’s electronics products. Over the past few years, Chinas’ factories cut human workforce by an astounding average of 50%, due to the increased prevalence of robots.

Are there Advantages of Workforce Automation?

Although there is definitely a negative side of workforce automation, do positive sides exist? Customers could experience, to an extent, cheaper and more effective services and products. This would be due to the cost savings of the autonomous robotics, which yield a one-time fee along with other basic upkeep costs. Lower production costs would also make it possible to build items in the U.S. vs overseas, which many would prefer.

 Automation Limits?

There are limits to mostly everything, and automation is no exception. Short product life cycles that quickly become obsolete and ability to entertain fully-custom projects do not fit into an automation system. For example, paying for a large number of robots to build an electronic product that will become obsolete in less than a year would not be a smart decision from a business standpoint. The ability to be flexible and custom is imperative when concerning several products in several different markets.

What does Second Machine Age Mean?

Robotics in machine automation is becoming a larger part of the workforce as time goes on. Some companies plan to simply increase production levels with the help of robots and robotics parts while keeping their employee count the same and reassigning their workers to other positions within the company. With the addition of robots and robotic parts in the workplace, workers will be needed to maintain robots, calibrate and monitor them, analyze data and more.

The rise of robots and robotic parts is unavoidable in several niches. Today’s technological prosperity is changing tomorrow’s workforce for good.

The latest version of NX continues to support end-to-end solutions for additive manufacturing, helping manufacturers realize the goal of using 3D printing for industrial production.

Part manufacturers proceed to face increased pressures from modified market expectations, with customers who require optimized accuracy and faster response times. In order to remain competitive, many part manufacturers look to digitalization, which connects all of the steps of part manufacturing planning and production with a single source of information, or a digital thread. Implementing a digital strategy can enable part manufacturers of all sizes to take greater advantage of automation, adopt 3D printing for production, and ultimately expand into new market opportunities and reduce time to delivery.

State-of-the-art automation enhancements within the latest version of NX provide powerful ways to expand production efficiency and decrease cost. Robotic programming technology provides the ability to automate complete manufacturing cells, including programming robots to perform machining. Adaptive milling and tube milling are new capabilities that provide innovative ways to automate CNC machines and accelerate cutting of complex parts. Adaptive milling is a high-speed cutting method that leverages automation within NX to decrease machining cycles by up to 60 percent while extending tool life. Tube milling streamlines the 5-axis programming process by eliminating preparation and minimizing inputs, utilizing advanced capabilities to create ideal tool paths and minimize errors in machining on the shop floor.

Mold and die manufacturers can now accordingly dictate tool production costs through integration between NX and the Teamcenter portfolio. Engineers can now use NX to automatically recognize features and parameters on the desired part, and provide pertinent information to Teamcenter, which can precisely calculate the tool cost. The newly integrated capabilities of Siemens’ product lifecycle management (PLM) software solutions can enable tool manufacturers to win more orders and increase profit margins through automated costing and accurate quotations.

New to this version, NX Machining Line Planner, combined with integrated NX CAM, enables the feature recognition, distribution, balancing, programming and simulation of operations over multiple setups and machines. Particularly helpful for industries with high-volume production of complicated parts with many features, NX Machining Line Planner uses a digital twin of the complete machining line and NX CAM feature-based machining technology to optimize the entire process. NX Machining Line Planner, combined with the power of the digital twin, offers a truly unique solution that enables automotive and machinery manufacturers to reduce planning time and increase overall production results.

The newest version also inflates the new additive manufacturing solution in NX by including the new module, NX AM for HP Multi Jet Fusion, which is certified by HP and powered by Materialise, to prepare print jobs for HP Jet Fusion 4200 3D printers. The NX software module will allow customers to develop and manage parts in a single software environment for Multi Jet Fusion printing solutions, avoid costly and time-consuming data conversions and third-party tools, and improve their overall design-to-finished-part workflow efficiency.

Additionally, Siemens develops applications for additive manufacturing process simulation in Simcenter 3D, a crucial tool to help manufacturers industrialize additive manufacturing by printing components the first-time-right. These simulation applications are an integral part of the Siemens’  additive manufacturing solution. Increasing productivity is one goal for most of those in the automation space (check out boosting factory automation productivity here). MRO Electric and Supply has new and refurbished Siemens products available.

IT and Robotics

IT and Robotics

IT and Robotics


Information Technology involves storing, retrieving, altering and transmitting massive amounts of data.

Because IT is heavily reliant on computers, automating the field is definitely the most practical direction.

Slowly taking rein in the sector, RPA (Robotic Process Automation) is terminating the manual effort associated with IT tasks and business processes.

RPA grips technologies such as AI (artificial intelligence), machine learning and vision, big data analytics and, eventually, quantum mechanics, to complete several tasks.

There are two types of automated deployments:

  1. Simplified robots (such as FANUC Robotics products found here) that execute a script to recurrently execute a specific function.
  2. Cognitive RPA/software-based AI that learns the tasks they are presented with and learn how to make choices on their own.

Currently, large global IT and BPO (business process outsourcing) organizations are using lesser forms of RPA.

Using RPA enables organizations to provide IT services at higher efficiencies and minimize costs.

Utilizing RPA enables organizations to provide IT services at increased efficiencies while cutting costs.

Many say that a handful of companies are currently in the early stages of conducting RPA proof-of-concept trials, while some are entertaining production pilots.

Affected Areas

Many IT service lines are expected to come under RPA’s influence.

  1. Helpdesk is a field that falls under this category. RPAs could potentially automate non-ticketing activities that, as per IT reports, occupy 25% to 40% of a helpdesk’s tasks. Some of these tasks include monitoring, providing clarifications and reporting. As for ticketing, RPA could assist in automation common service requests such as password resets.
  1. IT infrastructure outsourcing is another area that is expected to be impacted by RPA. In this, robots (such as FANUC motors, amplifiers, and drives) could observe critical thresholds and, under certain threshold breach conditions, could even fix the issue.

Companies have already started to leverage RPA for many of their client projects.

Processes that mandate RPA include rule-based, high volume, several systems, repetitive tasks, data mining, or data entry tasks. MRO Electric and Supply has new and refurbished FANUC Robotics products available. We also offer repair pricing. For more information, please call 800-691-8511 or email

Automation Advantages

  1. RPA slashes labor costs immensely.
  2. The technology offers a less prying way for integrating systems because software AI access applications through the user interface.
  3. Robots would connect to various UIs, including legacy green-screen applications, and would not touch the underlying software.
  4. RPA projects require less time and money when compared to traditional automation.
  5. AI robots will provide better quality, faster processing times (within hours compared to weeks with manual approach), major improvement in traceability for audit purposes, and increased high-speed analytics.
  6. RPA would easily scale and address fluctuations in volume.


Automation projects, as per industry experts, should not take more than a year to complete. They would likely cost between half a million USDs to two million or more, depending on the number of robots and their complexities.

fanuc robotics

A06B-6105-H002 – FANUC Robotics R-2000iA Servo Amplifier

The FANUC A06B-6105-H002 is a servo amplifier used with the FANUC Robot Module R-2000iA. Usually, these amplifiers are factory set for operation, so you do not need to set or adjust them. However, if you need to configure or troubleshoot your A06B-6105-H002, please follow the instructions below. Take note that before touching your FANUC Robotic drives, you should always check the voltage at the screw above LED “D7” to ensure that the remaining voltage is not higher than 50V.

The following table highlights the various LEDs on the A06B-6105-H002 and their meanings.

LED Color Description
P5V Green Lights when the power supply circuit inside of the servo amplifier outputs a voltage of +5V normally.
P3.3V Green Lights when the power supply circuit inside of the servo amplifier outputs a voltage of +3.3V normally.
SVEMG Red Lights when an emergency stop signal is input to the servo amplifier.
ALM Red Lights when the servo amplifier detects an alarm.
RDY Green Lights when the servo amplifier is ready to drive the servo motor.
OPEN Green Lights when the communication between the servo amplifier and the main board is normal.
WD Red Lights when the watchdog alarm is detected in the servo amplifier.
D7 Red Lights when the DC LINK circuit inside the servo amplifier is charged to reach a specific voltage.

If you need to replace the A06B-6105-H002 amplifier on your R-2000iA, ensure that you begin by first turning off the control unit main power. Next, detach the amplifier cover and pull out the cable. Check the screw above LED D7 with a DC voltage tester to make sure the remaining voltage is not above 50V. Remove the two screws located on the top of the amplifier. At the middle top of the drive, there is an M5 screw that fastens the amplifier during the transport of the cabinet. After installation of the cabinet, remove the screw as this will help improve maintainability.

After these steps are complete, you can pull the amplifier toward you using the handles located at the top and bottom. Be careful not to touch any components on the lower part of the drive’s PCB, and try not to damage any cables routed under the amp when pulling it out. Use a slanted angle when pulling it out. MRO Electric and Supply has spare FANUC Robotics AC and DC Drives available. For more information or to request a quote, please email or call 800-691-8511.

You can easily install a replacement by reversing the steps above. Lastly, be sure to check out our other robotics articles
