I am migrating from Masterdrive VC DC/AC drive to SINAMICS S120 DC/AC MoMo for Unwinder application. I have already configured all functions and drive settings and they seems to be ok. But I have troubles to find the correct signal to replace the old KK120 Actual position G1_XIST1. This was transmitted from Masterdrive VC to Simatic by Profibus DP free telegram as a double word. I tried to transmit r0482 G1_XIST1 Encoder 1 actual position 1 as double word but I think data resolution is different so the PLC is getting a wrong feedback and so the Unwinder operation is not appropiate. How can I configure an equivalent signal as KK120 from old Masterdrive so I can send it by Profibus as a double word to Simatic? Could you please suggest what parameters I am missing for this? Thank you! Victor Callejas SIEMENS El Salvador ------------------------------------------------------------------------------------------ Split from Encoder Resolution in SINAMICS S120 Drive.

For S120, the position controller function module must be activated for this conversion: Call up the "Configuration" in the Project Navigator and click on "Function modules/technology packages" and check the box for "Cl-loop pos ctrl". This allows the mechanics to be parameterised under "Technology" - "Position control" - "Mechanics" and the actual position value r2521 to be connected as feedback value.
