THE DRIVING INDUSTRY FORCE

Electrical drives are capable of serving a multitude of applications. Properly sizing those drives, and motors, requires an understanding of mechanical systems as well. That's where the expertise of a drives system engineer proves invaluable.

The goal of our drives system engineers is straightforward. Specify the most suitable motor and drive combination needed to run a load and determine the braking forces necessary to stop the system.

PROFITABLE EFFICIENCY

You run your company on cost efficiency and performance. We understand that everything matters in a competitive market and when specifying drive systems we keep this in mind. The drive system must be flexible to optimize all your processes, controls and it must be reliable to minimize downtime. We deliver these responsible solutions and expertise that are at your disposal when you need them.

CONFIGURATION AND MIGRATION

You run your company on cost efficiency and performance. We understand that everything matters in a competitive market and when specifying drive systems we keep this in mind. The drive system must be flexible to optimize all your processes and controls and reliable to minimize downtime. We pledge responsible solutions and expertise will be at your disposal when you need them.

  • Configuration - high density drive packaging, including applications in corrosive and hazardous locations, are economized by using high volume, pre-engineered custom packages that withstand even the toughest environments.
  • Migration - through bridge solutions and phased upgrades we can deploy a migration path that allows you to take advantage of new technology without breaking the bank.
 
WHY USE A DRIVE SYSTEM?

Purchasing an electric drive is a big investment. Anyone can sell you the drive that runs a motor, but not everyone can help you select an entire system that gives you one point of contact and ensures all the pieces and parts work together. Nobody likes to spend a great deal of money and leave the details to chance. A single source drive system gives you the peace of mind that your application will perform properly, efficiently and to its full potential.

REMOVING THE GUESS WORK
WHY USE A DRIVE SYSTEM?
  • Disconnect Switch - component ensures the safety of the drive, and the machinery attached to it, by immediately disconnecting power if the fuse trips from excess power current.

  • Line Reactors - help alleviate nuisance tripping of a drive.

  • Transformers - manage your power quality and fault.

  • CE Filter - main function is to reduce the radio frequency conducted emissions in the main supply lines and ground wiring.

  • Harmonic Filter - reduce the damaging effects of harmonic currents. This results in increased component life and reduced downtime while improving power factor.

  • Network Adaptor - provides plant-wide network systems using open, industry-standard networking technologies. It enables real-time control and information.

  • Drive Cable - carries high voltage power from drive systems to motors. This high voltage can cause corona discharges to occur between the conductors of conventional cables, causing damage not only to the cabling itself, but also to the motors, bearings, drives and related equipment. In turn, this damage can cause failure of the entire drive system, resulting in costly production downtime.

  • Electric Motor - plays an important role in your business. Controlling the way motors use electricity not only helps you save energy, but also reduces scrap and maintenance costs.

  • Encoder - allows for the positioning of the drive system and can be used for speed control.

  • Drive System Filter (Terminator) - provide motor protection by limiting voltage spikes for long lead applications.

  • Safe Off - provides a safety function which inhibits torque generation in the motor(s) powered by the drive.

  • Door Mounted Displays - provide a communication interface to configure and monitor your drive and its connected peripherals.

  • Ethernet Switch - automatically determines and remembers the devices connected to each port and routes messages only through the appropriate ports.

  • Programmable Logic Controller (PLC) - systems bring together existing and new systems through networks such as EtherNet/IP, ControlNet, DeviceNet, and many other network communication options.

  • Dynamic Brake Resistor - help protect drives from overvoltage faults by dissipating excess braking energy and heat. The size and type needed are dictated by the type of installed drive. Without the proper resistor, motors can and do overheat. This causes unwanted downtime and maintenance or system replacement - costing you time and money.

  • Gateway Networks - Stand-alone protocol gateways provide communication between several of the leading industrial protocols for Serial, Ethernet, EtherNet/IP Modbus Plus, Modbus TCP/IP, PROFIBUS, A-B Remote I/O, HART, Honeywell DE, Metasys, LONworks, BACnet MS/TP or BACnet IP.

 

EXCLUSIVE TO ROCKWELL - POWERFLEX DRIVES AND CONTROLLOGIX

  • PowerFlex 755 Drives with ADC
  • Firmware Supervisor automatically flashes back to original firmware.
 
WHAT WE OFFER

AC - Low Voltage Drives (VFDs)

To increase the productivity of your processes, improve energy efficiency and cut maintenance costs, you can rely on us to deliver the right low voltage AC drive up to 2,000 HP. We offer a complete spectrum of AC drives, from machinery drives for machine building to industrial drives for controlling processing lines, all the way up to industry specific drives with purpose-designed features and functionality.

AC - Medium Voltage Drives

To adapt the motor speed to your actual requirements, thereby optimizing energy consumption and reducing CO2 emissions we supply medium voltage variable frequency drives, up to 34,000 HP, for a wide range of applications.

DC Drives

You can use DC drives in almost any industrial application, either as part of a new installation or as a cost-effective retrofit. With programmability, built-in control programs, communication and I/O options, you can integrate them no matter what your process needs are.

Servo Drives

From single axis component drives to multi-axis modular drives, we offer solutions designed to help you simplify machine design while improving system performance.

Variable Frequency Drives (VFDs) - Most Popular Drive on the Market

VFD may be more expensive up front, but they can provide energy savings of up to 50%, thereby producing more cost savings over the life of the equipment. VFDs are used in applications where:

  • Complete speed control is required
  • Energy savings is a goal
  • Custom control is needed

TUNING YOUR VARIABLE FREQUENCY DRIVE (VFD)

  • Match the drive to the electrical characteristics of the motor by auto tune routines.
  • Match the physical load conditions to match the response of the drive to varying load conditions.
