Hello, Yes with the EPOS it's possible to "link" the 2 axis: You use one Position Controller to send his Output to both Speed Controllers: Drive_1, r2564 =» Drive_1, p1160 and Drive_2, p1155. And to have a good following error control for the Drive 2: Drive_2,p2531 = Drive_1, r2666 and Drive_2,p2530 = Drive_1, r2665. Finally put the normal Speed Setpoint N°2to 0:Drive_2,p1160 = 0%. I use Speed Septoint 1 for Drive 2 and Speed Setpoint 2 for Drive 1. That to have the possibility to move only one motor if needed and you can use p1142 touse the Drive 2 or not. It's work fine with 2 or more motors, I have a customer to use it with 4. But 1:1 synchronization. If you need to have an adjustable gear between the 2 axis, you could use DCC and this application example: http://support.automation.siemens.com/WW/llisapi.dll/38058120?func=ll&objId=38058120&objAction=csView&nodeid4=20229807&lang=en&siteid=cseus&aktprim=4&extranet=standard&viewreg=WW&load=content Have a good day, Denis. |
