Define the significance of the 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.
Table 5- 6 Connector inputs (CI) of the inverter (selection)
CI Significance CI Significance
p1070 Main setpoint p1522 Torque limit, upper
p1075 Supplementary setpoint p2253 Technology controller setpoint 1
p1503 Torque setpoint p2264 Technology controller actual value
p1511 Supplementary torque 1
A complete list of the connector inputs is provided in the List Manual.
Table 5- 7 Example:
$, r0755 755.0
p2253
Analog input 0 is the source for the speed setpoint.
Advanced settings
When required, you can smooth the signal, which you read-in via an analog input, using
parameter p0753.
