76 PFC configuration
PFC (Pump and fan control) and Autochange configuration
parameters. See also section Pump and fan control (PFC) on
page 103.
76.01 PFC status Displays the running/stopped status of the PFC motors.
PFC1, PFC2, PFC3 and PFC4 always correspond to the
1st…4th motor of the PFC system. If 76.74 Autochange
auxiliary PFC auxiliary PFC is set to Aux motors only, PFC1
represents the motor connected to the drive and PFC2 the
first auxiliary motor (the 2nd motor of the system). If 76.74 is
set to All motors, PFC1 is the first motor, PFC2 the 2nd. The
drive can be connected to any of these motors depending on
the Autochange functionality.
-
0000h…FFFFh Status of the PFC relay outputs. 1 = 1
76.02 PFC system status Displays the status of the PFC system in text form. Provides a
quick PFC system overview, eg. if the parameter is added to
the Home view on the control panel.

76.11 Pump/fan status 1 Shows the status of pump or fan 1. -
0000h…FFFFh Status of pump or fan 1. 1 = 1
76.12 Pump/fan status 2 See parameter 76.11 Pump/fan status 1.-
76.13 Pump/fan status 3 See parameter 76.11 Pump/fan status 1.-
76.14 Pump/fan status 4 See parameter 76.11 Pump/fan status 1.-
76.21 PFC configuration Selects the multi-pump/fan control (PFC) mode. Off
Off PFC disabled. 0
Reserved 1
PFC PFC enabled. One pump at a time is controlled by the drive.
The remaining pumps are direct-on-line pumps that are
started and stopped by the drive logic
The frequency (group 28 Frequency reference chain) / speed
(group 22 Speed reference selection) reference must be
defined as PID for the PFC functionality to work properly.
