Dear All, I have the following topology:
The above is controlled from a S7-400H station over Profibus. The mode of operation is n-setpoint specification and the following function modules are selected:
What I'd like to do is to add a SMC-30 encoder evaluation unit 6SL3055-0AA00-5Cxx which will then have a secondary encoder connected (differential TTL). Then using a separate DDS the control loop would be to follow the second encoder signal with a specific ratio. This is an electronic leadscrew application. I believe the application I'm trying to achieve is similar to the one found at this link https://support.industry.siemens.com/cs/ww/en/view/48947154 - but I am not able to download any document from there. Do you think it is possible to achieve my goal with the components that are available or some other hardware is required? Regards, Cezar Suteu |

Hello, for synchronizing to external encoder, DCC gearing application (GMC library) is necessary with CU320-2 and FW 4.x. https://support.industry.siemens.com/cs/ww/en/view/72839973 With your CU you need a S7-1511T or a D410-2. https://support.industry.siemens.com/cs/ww/en/view/109749263 |
