Define the analog input type
With parameter p0756[x] you specify the type of analog input.
Table 6-4 Default settings via parameter p0756
AI 0 Unipolar voltage input 0 V … +10 V p0756[0] = 0
Unipolar voltage input monitored +2 V … +10 V 1
Unipolar current input 0 mA … +20 mA 2
Unipolar current input monitored +4 mA … +20 mA 3
Bipolar voltage input (factory setting) ‑10 V … +10 V 4
AI 1 Unipolar voltage input 0 V … +10 V p0756[1] = 0
Unipolar voltage input monitored +2 V … +10 V 1
Unipolar current input 0 mA … +20 mA 2
Unipolar current input monitored +4 mA … +20 mA 3
Bipolar voltage input (factory setting) ‑10 V … +10 V 4
Defining the function of an analog input
You define the analog input function by interconnecting a connector input of your choice with
parameter p0755. Parameter p0755 is assigned to the particular analog input via its index, e.g.
parameter p0755[0] is assigned to analog input 0.
Example
$, U>@ >@
S
In order to enter the supplementary setpoint via analog input AI 0, you must interconnect AI 0
with the signal source for the supplementary setpoint.
Set p1075 = 755[0].
