The French Gerleman Motion Summit Recap

The French Gerleman Motion Summit Recap

Recently we hosted a Motion Summit, a complimentary event at our St. Louis branch covering the latest motion control updates with Rockwell Automation and our other motion automation partners. We demonstrated tools to design, develop, and troubleshoot motion control systems.

If you weren’t able to attend, here are some highlights from the presentations:


Rockwell Automation focused on Integrated Architecture and how it incorporates Motion Control into its Logix controllers.  Utilizing one common Ethernet/IP network, Rockwell is able to connect to I/O, servo drives (CIP Motion) and safety features (CIP Safety) within those servo drives

Rotary motors and actuators from Rockwell’s VP and MP series are designed to meet the needs of various industries, including those with wash down applications. Their Kinetix Servo Drives come in a broad range, from low-power indexing drive to high-power multi-axes drives. iTRAK and MagneMotion systems have Intelligent Track Systems that allow independent control of multiple movers.

Rockwell Automation also has safety built directly into its motion products. The most common safety feature is “Safe Off”, which interrupts gate power to prevent IGBT switching. This allows the drive to be disabled safely without removing power from the drive itself.  In addition to “safe off”, there are advanced safety features such as safe speed, safe direction, and safe position which allow personnel to safely interact with moving parts of a machine while it continues to operate.  For example, to allow a machine to be cleaned or serviced while it is running, safe speed and safe direction features might be enabled on a drive.  This would allow the operator to run the machine at a speed slower than typical production speeds, and in a direction such that he cannot be pulled into the machine, yet still have the machine produce parts. Conventional safety approaches can often hinder productivity, but these advanced safety features allow all of this to be done without losing efficiency.

They demonstrated their Motion Analyzer Sizing Software that makes it easier and more efficient to size and optimize motion control systems.  Rockwell also demonstrated the Load Observer and Dynamic Notch Filter features of the Kinetix drive which dramatically reduce the tuning process and automatically compensate for dynamic loads.


 Nidec-Shimpo is an Encompass Partner of Rockwell Automation, and an ISO 9001, ISO 14001 certified manufacturer.  Their products include high precision servo gearboxes, such as inline planetary, right angle planetary, right angle worm, rotary indexing, and pancake gear sets. Their gearboxes are lubricated for life, and active centering is standard on all products, allowing horizontal installation on equipment.


LUTZE covered the standards that need to be considered when choosing VFD cables, most notably the new standards outlined in NFPA 79 2018. What are the NFPA changes, and how do they affect VFD cable?

Paragraph 4.4.2.8 in the NFPA 79 2018 Edition states that “electrical conductors and equipment supplied by power conversion equipment as part of the adjustable speed drive systems and servo drive systems shall be listed flexible motor supply cable marked RHH, RHW, RHW-2, XHH, XHHW, or XHHW-2.”  This may eliminate using THHN cabling if NFPA 79 is required.

To make sure you comply with the new NFPA 79 standards, check the cable’s specification sheet to make sure it has one of the above designations. These ensure the cables are rubber high heat resistant, water resistant, and/or crosslinked high heat resistant. Avoid any designation that begins with T, as it stands for “thermoplastic” and should be avoided.

What cables would LUTZE recommend using considering this? DRIVEFLEX VFD cable is the most flexible in its class, easy to strip, route, and terminate, safer and more efficient. DRIVEFLEX VFD cable also has the lowest capacitance, highest impedance, full shielded, reduces shaft voltage, bearing failures, and nuisance tripping. Not to mention, it is also code compliant with the new NFPA changes.

Staying Ahead of the Electrical Trends and Standards

Last month, at our St. Louis branch, we offered customers the chance to learn about the latest trends and standards within the electrical industry at our Trends and Standards Update. Attendees gained knowledge on the latest innovative products that can help customers stay compliant with standards and the latest trends to help drive safety, technology and efficiency.

These high-level presentations offered cutting edge solutions to help customers stay ahead of the electrical trends and standards.  The seminar offered updates from Mersen, SolaHD, Thomas & Betts, Hubbell Wiring Device- Kellems and LUTZE.

These presentations covered the following:

Mersen covered SCCR codes and standards, including UL 508A standards. The UL 508A marking confirms that the industrial control panel has been certified by inspection. If the UL 508A’s construction requirements are followed, then a panel builder is eligible to have their panel listed by UL. Mersen also explained short circuit current rating (SSCR) and the importance of properly labeling panels for Arc Flash compliance.

SolaHD has updated its SDU Series DIN rail AC UPS. Their A Series still combines an industry leading compact design with a wide operation temperature range and unique installation options. The SDU provides protection from impulses and power interruptions that could be potentially damaging. This updated product also offers a new interchangeable optional “COMM Card” accessory, that allows communication between fieldbus protocols and industrial Ethernet. SolaHD has also introduced a new CF Relay Card option that has replaced the RELAYCARDSDU option.

Thomas & Betts has created an evolution of compression tools. Their Color-Keyed coding system allows high quality UL-compliant connections at a low installed cost. Thomas & Betts covered the basics on how to properly prepare cable, determine the proper connector, choose the correct tool/die and crimp inspection. They covered how the Thomas & Betts Blackburn Color-Keyed® compression connector system can make inspections and certified installations easier.

Hubbell Wiring Device-Kellems recently released the first UL Listed pop-up receptacle for countertops. To protect against spills, the receptacle assembly is sealed with patent pending silicone gaskets to repel liquids in both the down and up positions. The countertop receptacle is UL Listed to 498 Section 146 to be water resistant to a half gallon of liquid spilled on the device.

Hubbell also recently introduced both their Advantage Pin & Sleeve product line to promote safety and provide line of site disconnect and their inSIGHT Circuit-Lock™ Disconnects with LED indicators to promote workplace safety and improve troubleshooting time.

Do you know how Codes and Standards affect your choice of cables? The evolving NFPA 79 standard as well as NEC and UL 508a all have requirements on cable approvals. LUTZE highlighted how multi-listed cables are versatile and can help reduce the number of cables needed for code compliance. Also discussed were the latest trends in codes, standards and the general cable industry.  The great news is that LUTZE’s cables are designed for harsh environments and carry multiple approvals for standard and code compliance.

LUTZE DRIVEFLEX® Cable for VFD and Motor Applications

Variable frequency drive (VFD) cables have distinct advantages over traditional cables when used in drive and motor applications. When installed properly, VFD cables reduce cross coupling between drives and the shield contains and drains the electrical noise created by the drive. Their noise mitigation helps with the proper function of adjacent control systems and they help to reduce motor shaft voltage and bearing currents.

LUTZE DRIVEFLEX® cables are designed to cope with the power distortions in VFD applications. They offer superior electrical values for VFD or servo applications and are UL listed type “Flexible VFD Servo Cable, Flexible Motor Supply Cable” to comply with codes and standards regarding electrical wiring of VFDs. DRIVEFLEX® XLPE insulation has very low capacitance, high impedance and high voltage breakthrough resistance.  DRIVEFLEX® cables are safer and more efficient compared with traditional PVC/Nylon power tray cables or THHN wires in conduit.

LUTZE has recently expanded their DRIVEFLEX® line to include series A106 and A107, which are smaller diameter, general purpose series drive cables. Which type you use will depend on your specific project and requirements.

  • A106 series is great for most VFD applications and motors up to 40 HP and features a small outer diameter (OD) for easy routing and use in conduit.
  • A107 series cable is similar to the A106, but includes one shielded pair for brake or control signals.

Don’t trust your VFD and motor operations to tray cable or THHN.  Interested in learning more about DRIVEFLEX® or ordering it for your next project? Give your French Gerleman Account Manager a call today!


Electric Motor Bearing Failure and Use of the Proper VFD Cable

What causes bearing failure to occur between the variable frequency drives (VFD) and electric motors?  What can be done to minimize the potential for failure?

ball bearing

For starters, the ball bearing is the connection between the shaft and the motor frame.  There are two rings: an inner ring (which is in contact with the shaft) and an outer ring (which is in contact with the motor frame).  The shaft turns due to electromagnetic interaction between inductors on the shaft and inductors on the frame. When the shaft turns, it drives the machine.

The problem lies in the connection between the VFD and the motor.  The VFD send power to the motor and some signal contents reflect off the motor and move back towards the VFD.  The reflected waves collide with the upcoming waves and this causes high voltage spikes.  The high voltage spikes cause strong electric fields which then influence the motor.

The voltage spikes and strong electric field then produce a high frequency flux around the stator.  If this frequency flux becomes high enough to overcome the impedance of the bearings’ oil film, a current starts to flow.  The end result is spark erosion.  Tiny metal particles of steel balls and rings melt and the bearing eventually fails.

LUTZE Driveflex VFD XLPE A216

However, LUTZE has come up with the perfect solution and that is to minimize the electric field.  A symmetrical construction results in a smaller electric field. The DRIVEFLEX® A220 is the most capable solution thus far of preventing bearing currents.  It connects all three earth wires and connects the cable shield to PE on both cable sides.

So, there you have it! LUTZE has created the solution to your bearing current problems with the DRIVEFLEX® A220.

LUTZE presented this information in an educational session at our recent Product and Technology Expo.  Check out the full presentation here.
