Lenze Announces PositionServo Hardware Revision

/2 Comments/in /by

Lenze Americas is excited to announce the launch of the PositionServo with its new revision 2 hardware platform. The PositionServo’s new hardware platform is a drop-in replacement for 99% of the installed base while adding auto-tuning capability, programmable brake release delay functionality, plus ease of use upgrades to the MotionView OnBoard (MVOB) software.

“The auto-tuning capability makes tuning a servo drive effortless, it allows the user to quickly setup his application and if he needs more precise gain control, manual tuning in velocity and position modes is still available.” explains Lenze engineering support. No longer fixed at 10ms, the brake release time is now programmable to 2000ms in ms increments for precise application control.

“MotionView OnBoard (MVOB) Software is embedded into the drive to allow customers the simplicity of not having to worry about keeping track of their software,” explains Sandor Becz, Director of Engineering. “Now the user experience is greatly enhanced with the software upgrades including a new Monitor display, Rotational Direction parameter, Clear and Stop/Reset buttons, plus advanced feedback filter options. And now, upgrading the drive’s firmware is as simple as pressing the [Upgrade] button.”

The easy preconfigured Monitor screen allows the user to keep track of the active parameters and monitor I/O values in a single glance. The new Rotational Direction parameter allows users to quickly change the positive direction CW/CCW to fit their specific installation without having to recode all MOVED, MOVEP statements with negative values. A great time-saving tool in debugging and commissioning applications, the [Stop/Reset] button is available on every main software page making stopping the indexer execution and resetting the drive convenient and fast.

Minimize Your Downtime. Maximize Your Productivity.

Call Toll Free: 1.877.625.2402

Electrocraft/Reliance/Allen Bradley H series servo motors frequent our repair technicians here at Precision Electric. Over the years we have repaired hundreds of H series servo motors.

The H series servo motors have been around for a long time, and are obsolete. Since the H series servo motors have become obsolete, we highly recommend customers using this equipment to use Preventitive Maintenance plans with Precision Electric. This is to lessen the chance for an H series servo motor to become damaged beyond economical repair.

The H series servo motors are used with Electrocraft 2000 series amplifiers, Allen Bradley Ultra Plus amplifiers, as well as other products manufactured by Allen Bradley, Electrocraft, and Reliance.

The H series servo motor generally needs to be serviced more often than the servo amplifiers that run them. However, Precision Electric also sees H series servo drives/amplifiers in for repair as well. Our service technicians at Precision Electric keep large stock of parts for these products to speed up repair processes, and decrease cost for both Precision Electric and their customers.

CNC Machining & Dynamic Braking with High Frequency Output Inverter Applications 0-400hz

/in /by


We often receive inquiries for variable frequency drives that are capable of high frequency output. Spindle applications such as CNC equipment generally use a high frequency output, up to 400Hz.

Customers often have trouble locating the proper product for these applications. Precision Electric offers a few different options for these type of applications. Our number one recommended product for high frequency output applications is the Lenze/AC Tech SMV Drive.

The SMV drive is designed for several types of applications, including high frequency output. The standard maximum output on many variable frequency drives is 60 -120 hz. The Lenze/AC Tech SMV has capabilities from 0-400hz, right out of the box. We also offer other Lenze/AC Tech products that have a high frequency output option; such as the Lenze/AC Tech MC series and Lenze/AC Tech SCF series drives. However, if you need either an SCF or MC series drive with high frequency output, you must specify that you need the high frequency option. The SCF and MC series products do not come factory equipped with the high frequency option unless specified when your order is placed.

Machine Tool applications such as the spindle on a CNC machine often run their equipment off of high frequency inverters. Typically dynamic braking kits are required when using high frequency output on this equipment.

When CNC machines are running at high speeds the inertia of the spindle causes the motor to become a generator once the stop button is engaged. Voltage generated from the motor goes back onto the DC bus in the drive. This often will cause the drive to trip on an “over bus fault”. This problem is addresed by adding a dynamic brake kit to the drive. The dynamic brake switch will turn on when the bus voltage reaches a preset level to disapate this excess energy across a set of resistors. This will prevent the drive from faulting. The required resistor wattage is determined by the inertia of the load and often requires more wattage than a standard dynamic brake kit will offer. The expert sales staff at Precision Electric will assist you when selecting a drive/brake package for these applications.

Delta Tau CNC and Multi-Axis Engineering

/in /by
Quite often, on more complex moves, such as moving a laser (2D Motion) in a circle or a robot arm (3D Motion) from picking up a box to setting it down, more than one motor is required. A system is considered “multi-axis” when it uses multiple motors or feedback (axes) coordinated together (coordinate systems) to perform one or more specific tasks.

CNC (Computer Numerical Control) simply illustrates the complexity of mathematics required for a high precision system. These systems often interface with an Industrial PC as their HMI.

Unfortunately we find many multi-axis / CNC systems utilize proprietary amplifiers (drives) and motor combinations. We pride ourselves in using Delta Tau controllers, which can be used with virtually any 3rd party drive and motor combination. This makes it the optimal controller to retrofit an already existing system or building a new one from scratch.

An example of a System Controller, known as the Delta Tau UMAC, the controller can simultaneously control up to 64 axes with extreme precision (within millimeters).

CNC and Multi-Axis Applications Include:

– Robot Packaging Systems
– Laser Cutting Machines
– Water Cutting Machines
– Procedural Systems
– Custom Machining Systems
– Patterning Systems
– Bending Systems
– High Precision Systems
– Robotic Painting Systems
– 2D Linear Motion Systems
– 3D Space Motion Systems
– And Much More…

Industrial Manufacturing Infrared Thermography Services

/2 Comments/in /by

Infrared inspections provide a means to view systems (electrical, mechanical, building envelopes) under normal operating conditions to identify abnormally hot (or cool) areas or components. This is a powerful maintenance tool. In many instances, equipment failure is preceded by a period of increasing heat. This is especially true of electrical equipment.

With infrared thermography you can identify overheating electrical connections and other machine components, scheduling repairs to be made during planned downtime. This increases reliability and productivity for the entire operation.

This thermogram shows a loose connection of the lug on incoming power supply. Operating equipment with loose connections can
cause many problems, some damages could be un-repairable

Financial Savings

  • Fewer interruptions while in operation mean more uptime and greater productivity.
  • Equipment problems are fixed before they fail and damage or destroy the rest of the machine.
  • Identifying developing problems and planning the repairs results in fewer “panic situations”, those costly predicaments that force excessive overtime and monetary premiums for emergency rush equipment orders.

This thermogram shows a loose fuse clip that needs tightened or replaced. Loose fuse clips could lead to serious equipment damages.

Safety

  • An industrial process that runs reliably and without surprises produces a safer work environment. Many industrial processes are complex and run at high speed. A sudden failure on one machine can have a cascading effect of failures that may include flying debris.
  • Fire avoidance. Overheated electrical connections can start fires. You may have heard of a fire in your area that it was caused by “faulty wiring”. This means many things including bad design and overloaded circuits. It also commonly means a bad electrical connection that was overheating and was not found in time.

Other advantages of thermography:

  • Shows a visual picture so temperatures over a large area can be compared
  • Able to find deteriorating: (higher temperature components prior to their failure)
  • Measure or observe in areas inaccessible or hazardous for other methods
  • Non-destructive test method
  • Locate defects in shafts, pipes, and other metal or plastic parts

Call Precision Electric, and schedule infrared thermography services to prevent unnecessary damages to your industrial equipment.
