New Video Details High Performance Servo Motion Control

If your application employs servo motion control, prepare for some exciting statistics:

• 1 Gbps backplane throughput – higher than traditional networks
• Communications loop updated at 0.25ms intervals; position at 0.5ms intervals and path plane at 1ms intervals
• 64-bit floating point precision for motion and control
• Jerk-free technology
• Full scalability without performance degradation from 4 to 40 axes and beyond

Intrigued? PACMotion^TM servo motion control is setting a new gold standard that will benefit the widest range of discrete and hybrid applications, and this new video tells you the story in a nutshell. Don’t miss it.

  Does the new PacMotion platform offer analog output options?
  
  In older control systems, if you needed a high-speed ( <= 1 ms update) P&ID loop, you needed an external, dedicated high-speed loop controller to perform that function. More recently, there were PacSystems motion control modules with high speed analog outputs that could allow you to integrate high-rate control into the main chassis, even if it was not actually a motion-control application. However, it looks like those modules have been obsoleted. Looking at the PacMotion brochure, I did not see analog output capability. Did I miss that information, or, if not available through PacMotion, is there a different path to achieving this functionality with PacSystems components?

  Hi Jefferey, you are correct, the DSM cards has been discontinued. But, you can still control analog servos with the new PMM345 PACmotion module. You need to add a fiber terminal board that connects to the PMM module. The FTB has two +/-10VDC outputs. This works exactly the same as the old PMM335 PACmotion module if you were familiar with that.

  I went on the Emerson PACMotion website, but I can't find any information about the analog fiber board you mentioned. The information may be there, but I am having great difficulty finding it. Any suggestions? I have a potential application in mind and would like to have a detailed specification or manual for the trade study.
  
  Worth mentioning to your website team: It's hard enough to find information about the PMM345 in the first place. You can't find it listed as a product if you search for PMM345. Oddly enough if you search by the name "ftb", you can't find the FTB itself, but the one product that comes up is the "PACMotion High Speed Servo Motion Controller" (no ID #, but it is the PMM345). Entering "PACMotion Motion Controller" in the search bar will momentarily show you a link to the PMM345, but pressing <Enter> sends you to the Ovation control platform. When you finally dig your way down to the PMM345's page, there is only a brochure and a couple of high-level data sheets for PACMotion systems that don't mention anything about analog inputs or outputs.

  Hi Jeffrey, the main Emerson web site is sales oriented so there is limited technical information here especially for a new launch like PACmotion. You can generally find brochures and sales-oriented datasheets but for detailed technical information you can refer to our techncial support web site at www.emerson.com/iac-support. You can also contact your local Emerson office who will be able to provide more information. Search for full part numbers like IC695PMM345 and IC695FTB001.

  GFK-2448 PACMotion Multi-Axis Motion Controller User Manual has been the most helpful for me with the PMM345 card.

  Thanks Gary! GFK-2448 relates to the older IC695PMM335 module, GFK-3140 is updated to cover the IC695PMM345. From a configuration point of view the modules are very similar, programming is identical but the hardware interface to the drives changes from FANUC FSSB to EtherCAT.

  Jeffrey, just a heads up, depending on what you are going to do with the analog signals, we had some issues. We were trying to control a hydraulic cylinder with a proportional valve and transducer feedback in closed loop. We found that at times the cylinder wouldn't reach postion, and not give any type of fault, just continue to run with an "offset" in the process. (Example: if we told it to go to 100mm and it stopped at 90mm (physical obstruction, low pressure), when we told it to come back to 0mm, it would come back to -10mm, and continue to run, now between -10mm and 90mm instead of the programmed 0mm and 100mm). We've never had an issue with the FSSB fiber signal to the servo amp, only the +/- 10vdc. This was several years ago, at the time it was a GE product, and they didn't seem to think it was an issue.
