Setting The Deadband - Siemens SINAMICS G120D Operating Instructions Manual

Procedure
1. Set the DIP switch for analog input 0 on the Control Unit to current input ("I").
2. set p0756[0] = 3
You have defined analog input 0 as a current input with wire-break monitoring.
3. Set p0757[0] = 6.0 (x1)
4. Set p0758[0] = -100.0 (y1)
5. Set p0759[0] = 12.0 (x2)
6. Set p0760[0] = 100.0 (y2)
7. Set p0761[0] = 6
An input current < 6 mA results in fault F03505.
The characteristic for the application example is set.
