F07490 falut on Sinamics S120 Servo configuration

Sir,

We are facing F7490 fault on S120 drive. we know it is generating from PLC side but could not find which signal is missing where it was interconnected in drive.

Perhaps this link may help:

In the hardware configuration of your PLC , you should have the S120.

When you select it , you'll see in the input/output area message frames , it's possible that this has been used...

another option is that they've used an input of s120 (so an output of the PLC is triggering this)

either way you can cross reference the outputs and look it up in your s7-program 

we'll be able to help more if you would add some print screens :)

How can the Safety Functions of SINAMICS S120 be activated in an existing STEP 7 Project?
