Now OEMs and users can remotely monitor and control factory automation displays from anywhere in the world with a phone or tablet and an internet connection. Parker has released the Remote Manager mobile app that controls one or more Parker Factory Displays (PFD) or Interact Xpress™ HMI (and as a result of their machines). It’s a powerful “Information Anywhere” capability that allows users to perform a wide variety of tasks remotely and in real time:
Enabling this functionality is a simple matter of connecting Remote Manager to a PFD, which functions as a data aggregator pulling data from a variety of sources including Parker and third-party controllers and databases. The information is published to databases (e.g. MySQL) and then pushed out to the Remote Manager app through code (e.g. PHP) in a web browser.
“We’ve come to rely on Remote Manager. In our food processing and canning plant, there’s always water everywhere, so electronics are always at risk. The app gives us the ability to run and monitor our entire department wirelessly on iPad and Google Nexus tablets, away from water. And it’s so easy to use! The controls are fantastic and easy to learn. Set-up only required an IP address, and we were up and running. I can’t say enough good things about this app, and we’re hoping to tie in Parker Factory Displays soon to make the system even better.” via Christian Nondorf, Electrician / PLC Programmer, Del Monte Foods, using Remote Manager
The Remote Manager app is available for:
The Parker Factory Display (PFD) visualization system. PFD offers unprecedented flexibility and impact for delivering critical messages to associates on the factory floor. Whether presenting Andon display-type information, lean metrics, production status, OEE data, safety policies or employee announcements, PFD is much more than a "scoreboard" that simply displays text -- it provides workers with real-time, situational awareness for faster response to downs and non-conforming conditions.
The PFD comes packed with a new controller-only option, factory display options up to 55" for primary and secondary units and updated PFD software, which is 32/ 64-bit compatible. The new controller also includes two Ethernet ports, which allows the separation of the Office network from the plant network. With the addition of the Open Database Connectivity (ODBC) driver to the controller image, you can now connect to virtually any database!
With its high-definition resolution, flat-panel displays and built-in networking, PFD offers unparalleled visual impact for empowering associates. Its intuitive graphics enhance the message, while its distributed architecture easily integrates into existing manufacturing and IS infrastructure. Whether remotely publishing displays from anywhere via the Web or visualizing non-conforming parts on a production line, the Parker Factory Display does so much more than other production board displays and Andon display-type systems and at a lower cost.

With its high power density and flexible mounting capabilities, permanent magnet direct drive servo motors like the Parker PM-DD series have a proven track record in many manufacturing applications. Let's take a look at five successes spanning various industries.
As the world's communications infrastructure continues to grow and evolve, the demand for fiber optic cable has been increasing. With Parker distributor Cross Automation in Charlotte NC, we were able to provide PM-DD motors for a vertical lathe, used to dispense glass for fiber optic wiring. The combination of smooth low-speed operation, compactness, and the ability to mount directly to the rotating shaft made the PM-DD a winner over standard servo motors.
Machine tools demand accuracy, and in the second case study, the task at hand was to repeatedly index a table that was three feet in diameter. With displacement occurring 1.5 feet (457 mm) away from the motor centerline, its high resolution (20 bit) absolute encoder was critical to the application. Thanks to the PM-DD's high load carry bearings, (1500 N in this case) where previously a conventional servo motor and worm gear solution was used, the PM-DD proved to do the job while eliminating the worm gear. The drive train was simplified and ongoing maintenance associated with the mechanical gearing was eliminated. This solution was sold by Faber Associates, Parker distributor based in Clifton NJ.
Automotive assembly is a rigorous application with hundreds of interdependent operations, all of which must function reliably, at the risk of costly downtime. A rotary table was used in the operation of adjusting vehicle headlights. Simplicity and high positioning resolution were the main factors leading to the adoption of the PM-DD in an application solved by Parker distributor Reco-Wesco from Indianapolis. Being able to mount the motor directly to the table eliminated the need for multiple mechanical components that would have required maintenance and been a potential failure mode.
Automotive industry testing applications often duplicate real-life scenarios that the finished vehicles will be exposed to, but must take into account the worst-case situations. In this case, the PM-DD motor was used for an electronics test bench. Part of a multi-axis assembly, the test bench would simulate the rough vehicle road conditions, including a rollover, that the electronics might be subjected to. PM-DD was preferred over a standard servo motor due to its smooth, slow speed, operation, good bearing support and high torque. This solution was sold by Parker distributor RSA of Fond du Lac WI.
The fifth and final application was in the life sciences field. A PM-DD motor was used for an indexing table that carried five stations to support the assembly of medical devices. The first station was to load the part, second applied adhesive, third was for UV curing of the adhesive, fourth was inspection and fifth was where the part was unloaded. In this case, the PM-DD replaced a pneumatic indexing table. Key to its success was a smooth start and stop operation versus the previous pneumatic solution. Also, the PM-DD with Parker P-Series Drive allowed for a variety of indexing locations to be programmed providing more flexibility than a more traditional rotary indexing table. This solution was provided by Automation Incorporated, a Parker distributor out of Minneapolis MN.

The basic theory of operation for brushless servo motors revolves around the principles of magnetism where like poles repel and opposite poles attract. There are two magnetic sources found within a servo motor: Permanent magnets that are typically located on the rotor of the motor, and the stationary electromagnet that surrounds the rotor. The electromagnet is called either the stator or motor winding and is made up of steel plates called laminations, that are bonded together. The steel plates typically have “teeth” that allow copper wire to be wound around them.
Going back to the principles of magnetism, when a conductor like copper wire is formed into a coil, and the conductor is energized so that current flows through it, a magnetic field is created.
This magnetic field created by current passing through the conductor will have a north pole and a south pole. With magnetic poles located on the stator (when energized) and on the permanent magnets of the rotor, how do you create a state of opposite poles attracting and like poles repelling?
The key is to reverse the current going through the electromagnet. When current flows through a conducting coil in one direction, north and south poles are created.
When the direction of the current is changed. the poles are flipped so what was a north pole is now a south pole and vice versa. Figure 1 provides a basic illustration of how this works. In figure 2, the image on the left shows a condition where the poles of the rotor magnets are being attracted to the opposite poles of the stator. The rotor poles, which are attached to the motor shaft, will rotate until they are aligned with the opposite poles of the stator. If all stayed the same the rotor would then remain stationary.
The image on the right in figure 2 shows how the stator poles have flipped. This would happen every time the rotor pole caught up with the opposite stator pole by reversing the current flow through that particular stator location. The continual flipping of stator poles creates a condition where the permanent magnet poles of the rotor are always “chasing” their stator opposites which results in the continuous rotation of the rotor/motor shaft.
The flipping of the stator poles is known as commutation. The formal definition of commutation is “The action of steering currents to the proper motor phases so as to produce optimum motor torque and motor shaft rotation”. How are the currents steered at the correct time to maintain shaft rotation?
The steering is done by the inverter or drive that is powering the motor. When a drive is being used with a particular motor an offset angle is identified in the drive software along with other things like motor inductance, resistance, and other parameters. The feedback device that is used on the motor (encoder, resolver, etc..) provides the position of the rotor shaft/magnetic pole to the drive.
When the magnetic pole position of the rotor matches the offset angle, the drive will reverse the current going through the stator coil thereby changing the stator pole from north to south and from south to north as shown in Figure 2. From this you can see that letting the poles align will stop the motor shaft rotation, or changing the sequence will get the shaft spinning in one direction vs. the other, and changing them quickly allows for high speed rotation, or just the opposite for slow shaft rotation.
