The scenario
A VFD-controlled pump system uses a pressure sensor to provide feedback, allowing the drive to adjust motor speed for constant pressure.
What is in this drawing
Read the decisions behind it.
01
Model VFD as a block with 3-phase input, control input, and 3-phase output.
02
Represent pressure feedback as a voltage source signal into the VFD block.
03
Use motor block for the pump load.
Applicable to industrial pump control circuits, HVAC systems, and any fluid handling process requiring variable speed drive.
