Group 81: PFC Control

Parameters for Pump-Fan Control (PFC). “Appendix B” on page 157 gives detailed information on 
PFC. “Application Macros” on page 53 describes the default signal connections.

Code Description

8103

REFERENCE STEP 1
Sets a percentage value that is added to the process reference when at least one auxiliary (constant speed) 
motor is running. Default value is 0 %.

Example:

 

An ACS 400 operates three parallel pumps that pump water to a pipe. The pressure in the pipe is 

controlled. The constant pressure reference is set by parameter 4020 

INTERNAL

 

SETPNT

.

At low water consumption levels, only the speed regulated pump is run. When water consumption 
increases, constant speed pumps are started; first one pump, and, if the demand is still growing, the other 
pump.

When water flow increases, the pressure loss increases between the beginning (measurement site) and the 
end of the pipe. By setting suitable reference steps (parameters 8103 

REFERENCE

 

STEP

1 and 8104 

REFERENCE

 

STEP

2) the process reference is increased along with the increasing pumping capacity. The 

reference steps compensate the growing pressure loss and prevent the pressure drop at the end of the 
pipe.

8104

REFERENCE STEP 2
Sets a percentage value that is added to the process reference when at least two auxiliary (constant speed) 
motors are running. Default value is 0 %. See parameter 8103

REFERENCE STEP 3

speed) motors are running. Default value is 0 %. See parameter 8103
