  1. Hi MIke, After we double checked it seems you are right. You need to connect a device on the Y1 or Relay output. Use Modbus 200BH, the corresponding signal can be output according to the setting value of Modbus. When it is set to 1, the output is ON, and when it is set to 0, the output is OFF. In this case, it's a way to send a virtual signal to Y1 or Relay output.
  2. Hi Mike, the VFDs outputs can't be defined as general purpose outputs hans cannot be set using communication.
  3. Hi Mike, Since our VFDs are communicating using MODBUS RTU the limitation is 31 (If you need more then that you will have to add another modbus port and implement the communication manually) I\Os (digital and analog) can be red using communication so it seems that your paln should work. Please note that since it uses a serial communication it is recommanded using the "read parameter" element instead of reading all values from every VFD and so improve the response time
  4. Hi, if you are pulling a foil many times only one axis in pulling while the other needs to mantain \ control the tension. In that case the "master" pulles according to the requested command (position\velocity) and the 2nd axis just work in torque control (with max velocity limitation) so it doesn't care about the actual movement. If you wish to consult and dissscus in details you can contact our tech-support by submiting a ticket: https://support.unitronics.com/index.php?/ticket/submit-ticket
  5. This? I can't garentee...probobly two realeses from now. But if you don't have the time for that please email me. David.
  6. Syncronization basically means both axes will make the same travel at the same time. But just like your mechnical system have it's own tolerance the syncronization has it's own tolerance as well. 1. So for some application just tuning both axes and executing a "Single axis" simultaniusly will do just fine. 2. For others you can use an internal loop withing your control application- set one axis as "Master" and then check for the position diffrance between them, The diffrance can be used as a factor to a PID function that increases the "Slave" velocity at the position block in order to reduce the lag\lead of the slave comparing to the Master.(Dont forget to allow "Contiues update" bit) 3. You can wait for the MC_GearInPos block that will be introduced soon un UniLogic for Cyclic Ethercat functionallties
  7. Basiclly you are right, but... Unitronics is now in the process of imlementing a new VFD product line (UMI-B7) That VFD support Encoder extention cards and support Close-loop. (Position and Velocity ) including "Standstill" capability. If you need more information please contact Support@unitronics.com and provide more information about the application.
  8. Hi Soner54 As a policy we support our motion solution (and the servo in particular) as a part of a unitronics eco-system. Due to that we do not provide an EDS files for our drives. Since Unitronics servo drive works according to DS402 standard, using another file can be an option. However we can't guarantee it will work flawlessly. Can you please share more details about the application?
