Why Rexroth? Top Four Reasons to Choose Rexroth Drives & Controls

Todd Sharp, Motion Control Sales Manager, CMA/Flodyne/Hydradyne

CMA/Flodyne/Hydradyne is a leader in the design and commission of drive and control
systems for our customers for over 30 years, and one question that we often hear is “Why is Rexroth the best?”  There are many brands competing for the drive and control market, and here at CMAFH, we have working experience with most if not all of them. Our engineers program,  repair and upgrade many of the brands of control systems, and we have the ability to integrate any brand into our custom projects at our customer’s request. Having specialized in Bosch Rexroth products for many years, we understand the unique strengths of the product line.

Rexroth drives and controls can be differentiated from competing brands in four very distinct ways.

1. Product Breadth

The IndraDrive product family spans the power range from 100W to 4MW. This product family can operate as an open loop frequency drive/sensor less vector drive up to a multi-axis integrated motion and logic controller that can be either stand alone or drive resident. The IndraDrive product family also includes a cabinet free drive integrated motor. This entire IndraDrive product family is supported by the same software.Indradrive 2016 13187

  • Power range from 100W to 4MW
  • Range of technology from open loop V/F and sensor-less vector control to multi-axis integrated motion and logic control
  •  Integrated motion and logic control – controller or drive resident
  •  Cabinet free drive integrated motor

2. Connectivity

Rexroth’s drive and control platform supports all common communication buses including Ethernet I/P, EtherCAT, Profinet, SERCOS, CANopen, Powerlink, Profibus.
We can control 3rd party motors regardless of brand or type, and we can operate all common feedback types including TTL, 1vpp, Endat, Hiperface, SSI, resolver. Our drives are available with a 2nd encoder input with a 1MHZ input frequency. Our control supports all common machine programming languages like ladder, FB, ST, IL… plus all common IT and engineering languages like C#, C++, Java, Labview, Matlab.

  • Supports all common communication buses including, Ethernet I/P, EtherCAT, ProfiNet, SERCOS, CANopen, Keyvisual_inkl_Logos_w486Powerlink, Profibus
  • Controls all 3rd party motors regardless of brand or technology type
  • Operates all common feedback types (TTL, 1vpp, ENDAT, Hiperface, SSI, resolver) with drive based second encoder input with up to 1MHZ input frequency
  • Supports all common machine programming languages (ladder, FB, structured text, instruction list) plus all common IT and engineering type languages like C#, C++, Java, Labview, Matlab

3. Functionality

Whether it’s drive or controller based, Rexroth offers multi-zone tension control, vibration dampening/anti-slosh control, high speed registration control, advanced electronic camming and hydraulic control. We also support zoned safety control with safe torque off and full safe motion; controller or drive based. Yes, drive based safe motion control!

  • Vibration dampening/anti-slosh control
  • High speed registration control
  • Advanced electronic camming
  • Supports all common hydraulic functions
  • Integrated safe torque off and safe motion control

 

4. Support

Rexroth designs, engineers and manufactures all products they sell. All are standard and sold throughout the world. In the US, hundreds of local high-tech distributors are Rexroth trained and certified to provide full sales, service and application support.  Additionally, Rexroth maintains sales, service and application support facilities in every region of the US, plus scores more globally.

Nine steps to the proper drive

Guest contributor, Bosch Rexroth

A fully structured approach, well-founded knowledge of the formulae and a fundamental understanding of the technology are essential to designing drives. These are the prerequisites for perfect matching of the machine and the drive.18089-x734_w734

Drive engineering is undertaken when the machine is initially designed, and also when the requirements for the machine have changed or a retrofit is due. Leaving excess tolerances – either upward or downward – is counterproductive for the design. If the drive is under-dimensioned, then the machine will not achieve the desired performance level and, in the worst case, the drive will have to be changed out for a more powerful one. That involves major outlays. The procurement costs will rise and because of poor efficiency, the life-cycle costs will increase. But what does designing a drive mean? It means laying out the motor’s torque curve so that it ideally matches the needs of the machine being served.

Technical understanding is a prerequisite

Software can provide assistance when calculating and planning the drive. It can save time, for example, when several versions have to be analyzed. With the help of the IndraSize engineering tool made by Rexroth, users can select IndraDyn motors and IndraDrive drives simply by entering parameters. But in spite of this support, the technician or engineer has to bring with him or her a fundamental understanding of the technology involved. Technical understanding will allow critical magnitudes to be taken into account so that  we will recognize how the drive might be optimized. Whether with software support or without – the calculations for the proper drive can be carried out in nine clear steps.
