You have the following options when selecting the source of the main setpoint:
● Inverter fieldbus interface.
● Motorized potentiometer simulated in the inverter.
● Fixed setpoints saved in the inverter.
You have the same selection options when selecting the source of the supplementary
setpoint.
Under the following conditions, the inverter switches from the main setpoint to other
setpoints:
● When the technology controller is active and appropriately interconnected, its output
specifies the motor speed.
● When jogging is active.
● When controlling from an operator panel or the STARTER PC tool.

Specifying the setpoint via the fieldbus
Interconnecting the fieldbus with the main setpoint
Figure 8-4 Fieldbus as setpoint source
Most standard telegrams receive the speed setpoint as a second process data PZD2.

Remark
p1070 = 2050[1]
Main setpoint
Interconnect the main setpoint with process data PZD2 from the fieldbus.
p1075 = 2050[1]
Additional setpoint
Interconnect the additional setpoint with process data PZD2 from the fieldbus.
8.3.3
Motorized potentiometer as setpoint source
The "Motorized potentiometer" function emulates an electromechanical potentiometer. The
output value of the motorized potentiometer can be set with the "higher" and "lower" control
signals.
