Advanced commissioning
7.3 Setpoints
The inverter receives its main setpoint from the setpoint source. The main setpoint generally
specifies the motor speed.
Figure 7-9 Setpoint sources for the inverter
You have the following options when selecting the source of the main setpoint:
● Inverter analog input.
● 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.
