Selecting frequency setpoint sources
Selecting the setpoint source [P1000]
The speed of the motor can be set via the frequency setpoint. The following sources can be
used to specify the frequency setpoint:
●
Analog inputs
●
Fixed setpoints
●
Motorized potentiometer
●
Fieldbuses
The frequency setpoint sources available depend on the frequency inverter version.
●
For frequency inverters with a fieldbus interface, the 'fieldbus' (P0700 = 6) is pre-selected
as the frequency setpoint source.
●
For frequency inverters without fieldbus interface, the analog input (P0700 = 2) is pre-
selected as the frequency setpoint source.

Parameter
Description
P0003 = 1
Access to the most frequently used parameters
P1000 = … 0: No main setpoint
1: MOP setpoint / motorized potentiometer (P1031 … P1040)
2: Analog setpoint (P0756 … P0762), factory setting for frequency inverters without
fieldbus interface
3: Fixed frequency (P1001 … P1023)
4: USS on RS 232
6: Fieldbus (P2050 … P2091), factory setting for frequency inverters with fieldbus
interface
Adding setpoints from different sources
You can add several setpoints via frequency setpoint source P1000. For more information,
see the List Manual (P1000 in the parameter list and function diagram 5000).
