2. Set the switch associated with the analog input. You can find the switch on the Control
Unit behind the front doors.
You have now defined the analog input type.
Characteristics of the analog input
If you change the analog input type using p0756, then the inverter automatically selects the
appropriate scaling of the analog input. The linear scaling characteristic is defined using two
points (p0757, p0758) and (p0759, p0760). Parameters p0757 … p0760 are assigned to an
analog input via their index, e.g. parameters p0757[0] … p0760[0] belong to analog input 0.
