Setpoint selection

The following settings are possible as the setpoint source. You can select the setpoint source with parameter P100.

  • Unipolar / Fixed setpoint: The setpoint "0" applies as long as no setpoint is selected. The FBG setpoint adjuster can be added to the setpoint "0" or a fixed setpoint using P121.
  • P163/164/165 setpoint n11/12/13 scales PI-controller [0 – 100%] step width: 0.1%
  • P173/174/175 setpoint n21/22/23 scales PI controller [0 – 100%] step width: 0.1%
  • Operation with optional second analog input (e.g. FIO11B)
  • The setpoint from the AI2 analog input applies as long as no setpoint is selected. The FBG setpoint adjuster can be added to AI1 or a fixed setpoint using P121.
  • RS485/fixed setpoint
  • SBus 1 / Fixed setpoint: Specify the setpoint and set it using the following bus ­parameters:
  • P870/871/872 setpoint description PO1/PO2/PO3 [PI controller setpoint %]
  • PO1/PO2/PO3 = 0 – 214 = 0 – 100% PI controller setpoint
  • Setpoint selection is always unipolar. The inverter restricts negative setpoints (e.g. via RS-485 or SBus) to "0".
  • SBus 1 / Fixed setpoint: Specify the setpoint and set it using the following bus ­parameters:
  • P870/871/872 setpoint description PO1/PO2/PO3 [PI controller setpoint %]
  • PO1/PO2/PO3 = 0 – 214 = 0 – 100% PI controller setpoint
  • Setpoint selection is always unipolar. The inverter restricts negative setpoints (e.g. via RS-485 or SBus) to "0".
  • SBus 1 / Fixed setpoint: Specify the setpoint and set it using the following bus ­parameters:
  • P870/871/872 setpoint description PO1/PO2/PO3 [PI controller setpoint %]
  • PO1/PO2/PO3 = 0 – 214 = 0 – 100% PI controller setpoint
  • Setpoint selection is always unipolar. The inverter restricts negative setpoints (e.g. via RS-485 or SBus) to "0".
  • For all setpoint sources: The FBG setpoint adjuster can be added to the setpoint or a fixed setpoint using P121.
  • The settings Bipolar / fixed setpoint, Motor potentiometer / fixed setpoint as well as Fixed setpoint + AI1 and Fixed setpoint × AI1 do not have any effect. If you set these, the inverter always specifies the setpoint "0".
  • Frequency input / fixed setpoint
