I have a CU-320-2 DP communicating to a SST Profibus Master in an AB Chassis.. We have three S120 Sinamics Drives.. I am using the PZD Word 370 for the Infeed and Free Telegrams for the drives..
I have the Safe Off working with an input to the CU.. The drives ramp to a stop but then the only way that I have been able to reset the fault is with a power cycle.. I have read the manual and I am just not sure how to reset the fault..The manual indicated that I could set P9507.0==1.. I didn't see how to go about doing that..Also, I read a note in the manual that stated if the Basic Functions via Terminals was selected, you could deselect the STO via an input.. This sounds simple but when I selected the inputs, I wasn't allowed to see an input to deselect the STO..
I wasn't sure if I was Profisafe with the Profibus or how that was defined..
Any help would be appreciated..
