  1. PF527 Bus undervoltage user limit

    Thanks for helping. You gave me good information. Feeding power to the PF527 is coming throught the energy transmission chain, I need to check this cable and the connections. Also connection to the motor too. Motor is used in a conveyor, there is quit fast ramp 'running speed during 1 sec'. I have not seen any problems with that before, I think this is still fine. Undervoltage limit seems to be 65%, I think this is fine. I have not changed that, it is in a default value.
  2. I had axis fault, which stopped the PF527. Only way to go on was to switch power off and on again. Checking the faults&alarms, I find out that the reason was Bus Undervoltage user limit. This made 'Immediate Stop' for the PF527. Looking at the parameters, I can not find any parameter for this. In the manual it is said 'DC Bus voltage level is below user defined limit given by Bus Undervoltage User Limit, or device defined limit if the user limit attribute is not supported.' What does it mean?  Is there parameter for this limit? Checking the AXIS_CIP_DRIVE tag parameters, DCBusVoltage is not showing anything, why is that? => Reason found, not marked in 'Axis properties' Cyclic Parameters page
  3. PF527 opto digital output

    This is clear now, I had a wrong connection. I did not have 'sinking' connection. Thanks for helping!
  4. PF527 opto digital output

    I need to use digital outputs of PF527 drive. Controlling the outputs, it does not do anything. Relay outputs are working fine, but opto outputs do not work. For the outputs, there are relays connected, using pin 6,7 and 17.
  5. PF527 Control Sync Alarm / Module Sync Alarm

    Fixing the physical cables and connectors seems to help. Looks like problems were in a bad net. After the fixing net, I have not been problems anymore. Good advices!!!
  6. Hello Sirs! I have a problem with PF527. I get alarms 'control sync alarm' and 'module sync alarm' occasionally. I suppose this meaning that PLC is missing some data from the PF527 device. How to confirm this or what should I do with the problem? Any ideas? Motion group update period is 8ms. Also this device is the last device in the ethernet line. I am thinking to pull the cable directly to the switch near PLC. I am not sure does it help?  
  7. Problem solved. It is needed to make double klik for the PV800_App1 and then I get selecction window to choose panel layout. After this it is greating the folder three. This was the first time for me to use Connected Components Workbench. For the other components, it is not needed double klik, so I was a little confusing about this.
  8. I am creating the project with Connected Components Workbench, adding the panel. It will not create the folder three to the project. I have the standard version. How to program it now?  
  9. Hi! PresentCounter is not updating real pulses from the countercard to the PLC. This is why it is 'jumping'. Countercard is faster than the PLC reading. If you use countercard output, it will work with correct pulse amount, for comparing the pulses. I am not sure, what you were meaning, but this is the reason for 'jumping'
  10. Powerflex 527 rotating after MSO instruction

    Here is more specific of my problem. Setting the servo on, it will enable the MSO, if xxx.ServoActionStatus is not set. After I receive the xxx.ServoActionStatus signal it will take about 2 sec. Then it will set the MAJ instruction on and start rotating. Problem is that when MSO is set, motor start already rotating. This 2 sec moment I can not control any possible way, ramp times etc... My idea is to set MSO already on and wait the right moment to start the motor. When I give the start command, it should be starting to run immediately. Anyone experience of this?
  11. I am controlling the powerflex 527 drive with MSO instruction, first setting the drive on and then running the motor with MAJ instruction. After MSO instruction, motor is rotating about 2 sec and then stops to wait the  MAJ. I have not find any solution for this. My configuration is frequency control, no feedback, sensorless. One hint i found from the rockwell pages but it did not help me. Rated slip speed is set to zero.  
  12. Hi i would like to know how you solved the factorytalk private directory problem by firewall setting? As i am currently having the same problem. 

  13. Hi! I had this same problem too, I was installing the program and could not open or create any projects. In my case, problem seems to be firewall. When I accepted this in Firewall settings, everything works fine.
  14. I found the solution now from internet.... Restarting does not help but when I deleted 2 existing files in project PrivateDirectory - folder, I was able to open my project again. Program was creating these 2 files by itself again. Probably, there was some damages with these files.... If someone have more knowledge of these files, I would be happy to understand it!!!
  15. Now I am very much worried, I can not even restore my earlier backup file (.apa). I do get an information Unable to restore the application ..... Please check - there is sufficient disk space - the application is not open elswhere - The destination application does not already exists Items 1 and 2 are checked, last one I do not know what does it mean. Removing the project files or leaving it to the folder does have any affect .
