  1. I haven't watched your posted video yet, but.... Parameter 36, Motor NP RPM; is that value correct? 115 RPM seems awfully slow. Have you tried changing Parameter 47, Speed Reference to Drive Pot? If it starts behaving then you know the drive is ok and the problem is with the external speed reference source. As for the pulse train input, have you moved the jumper for DigIn on terminal block 7? This must be moved to Pulse In for that feature to work. I doubt this has anything to do with it but... The PF525 carrier frequency is 4KHz at anything above about 15 simulated Hz output. When you drop below about 10 simulated Hz output, the carrier frequency changes itself to 2KHz, then back to 4KHz when above 15Hz. Those aren't exact numbers, though. I've played with this many times using a scope on the output terminals UVW while watching the "Hz" on the PF525 display, and that 10 to 15 Hz area is a sort-of deadband for the carrier freq change. But it doesn't always hit on the exact values; just very near them, and you've said your values are hitting exactly every time. For all I know you could be experiencing this on a test bench but if you have any ambient EMI is the 2 to 4KHz range (other drives running nearby without shielded cables, welders, two-way radios, etc) that *could* be causing your issue. I know it's a stretch but once in a very great while I see something freaky like this.
  2. I've always associated recipes with FactoryTalk ME/SE or FactoryTalk Batch software. From FactoryTalk, a recipe merely loads a pre-defined set of values to a pre-defined set of tags, usually the controller tags. The only way I can think of to create a recipe in Studio5000 is to use sequencers in ladder, or maybe write recipe steps in SFC code.  I looked in the Studio5000 help and can't find anything that directly references native recipe instructions or tools. If anyone knows of Studio5000 recipe instructions or tools, or has another "trick" up their sleeve, I'd love to hear about it.   Recipe.pdf
  3. open rss file

    Your file is posted here as a .com and I can't open it. Can you post it as just a .RSS?
  4. I've found that the best, easiest way to add modules is to physically install them, power up the chassis and any remote I/O, get online with the controller and use the Module Discovery feature. If the modules are showing up on the catalog list, they're should be compatible with Allen Bradley controllers. But that doesn't mean that every Wago component is compatible with every AB controller. As @pturmel suggested above, I'd get my hands on any literature about the module you're trying to add and see if there's a compatibility issue or other restriction that's keeping you from adding that module to your particular configuration.  If you are missing an EDS, check to see if you can upload the EDS directly from the module via RSLinx Classic. This can be done on most Allen Bradley controllers and communications modules, but I'm not sure about 3rd party modules.
  5. RAU Questiions

    Rockwell has several training and certification programs, the most common of which is the Studio5000 Programmer and ControlLogix Maintainer certificates. While there are five levels of training available, successful completion of only levels one, two, and three are required for testing eligibility. @Integrator for life, is this the program you're going through, or are you participating in one of Rockwell's internal sales- or field service engineer training programs? Where are you taking the classes? @Mickey, RAU = Rockwell Automation University. For almost all of Rockwell's certification programs, the tests are online and timed. While there are typically less than 100 questions on any given test, they are randomly pulled from a bank of thousands of questions. As you can imagine, Rockwell doesn't exactly publish that list. The biggest tip I can give people going into a Rockwell online test is that you can navigate back and forth through the questions. Therefore, don't waste time on a hard question; just write down that question number and move on. Once you've answered all the questions you're certain of, go back spend the remaining time on the head-scratchers. The only other thing the OP can do here is tell us which questions he/she had a hard time with after the fact.
  6. Use the Studio5000 Task Monitor. It runs as its own application, connects to the controller via RSLinx Classic, and monitors modules, tasks, performance, connections, etc and should help you quickly narrow down what's eating your memory.
  7. I've been tinkering around in CCW V21 over the last couple of days and can't find anywhere to download to a single DPI port. In older versions you could swap something like an extended I/O card out of a PowerFlex-755 and upload/download that card's parameters, only. Did they remove that feature or just hide somewhere I can't find?  They just released V22 last month but I don't think I'll download that one just yet because the release notes say that the trend tool is disabled. 
  8. Good call, @Joe E. 011120006.pdf
  9. I can't get the third one to attach. Even though it is only 2.99MB, it won't take it. I even zipped it down to 2.77MB and the silly thing still wouldn't take it. Anyone have any suggestions as the why MR PLC won't let a doc attach?

  11. Yesterday I went through the FTView Studio manual and the user manuals for the PanelViews, themselves. Nothing specifies whether data is retained when navigation away from the display. Since they don't spell it out, it would be nice to compare the two models side-by-side.
  12. Any safety PLC to replace PILZ plcs?

    I am not familiar with PILZ but Allen Bradley's safety PLCs are GuardLogix and Compact-GuardLogix. They are both programmed from Studio5000. 
  13. @VFD Guy I think the problem the OP is having is that he can't get his PowerFlex 525 to work as a stand-alone. If I'm remembering the thread correctly; the drive works well from the network but will not work in manual when disconnected from the network. I believe he's trying to control start/stop/speed from the keypad and pot on the drive, itself, and not getting anywhere, even after disconnecting from the network and changing the appropriate parameters. 
  14. Agreed. Something else is wrong. 
  15. @Joe E. To answer your question, I don't know for sure. I've always associated factory resets with drive parameters, not with ADC. The ADC feature is enabled from ControlLogix in Studio5000 and I've never had to disable it once set, so I can't say with any degree of accuracy if a reset (from something like the Setup Wizard in CCW) would have any effect on ADC. I think that if it's enabled in the device definition in Logix and that drive shows up on the network, Logix is going to write configuration data to it.  I had the opportunity today to fool around with both a PF755 and PF525 with and L73 controller. This is what I found before getting kicked out of the lab: If ADC is enabled and the drive is removed from the network (like unplugging the Ethernet cable, as the OP says he's done), then you can make parameter changes and the drive will respond to the changes. Once the network cable is plugged back in the drive goes into a fault, re-boots, and comes back up with the parameter values written from Logix via ADC.  All that to say, it wouldn't matter if the drive is owned by a controller with ADC active. Once the drive is disconnected from the network it is a stand-alone and should respond to program changes, and be operable from the faceplate.
