automatan Posts: 57 Rating: (1)	Hi All, I am trying to control sinamics s120 double motor module via CPU315-2DP. I configured telegrams on both the sides PLC and Drive(Aligned telegrams with Drive ES basic). I can access Control unit CU320 from PLC. But when i try to control servo unit via relevant PZD words, i get I/O access error in CPU315. I will be very happy, if anyone guides. Thank you.

automatan Posts: 57 Rating: (1)	Dear sir, Thanks for your vauable reply, i sort out the problem that i faced. Now i have to run the drive with direct set point/ MDI positioning. i have enabled the following signals: Control signals ON/ OFF, Operation Enable, Intermediate stop , reject traversing task, MDI Selection, Positioning type, set point acceptance, position setpoint-300, velocity setpoint-600, EPOS enable basic positioner, EPOS Pos.actual value valid, feedback signal. In the STARTER Software am seeing following status bit enable: set point avaliable, MDI active, Inactl<speed threshold 3. But no run command to the drive. I am missing something small but left. Please guide me what i am missing.
