110 Application macros
PFC control macro
This macro provides parameter settings for pump and fan control (PFC) applications.
To enable the macro, set the value of parameter 9902 APPLIC MACRO to 7 (PFC
CONTROL).
For the parameter default values, see section Default values with different macros on
page 165. If you use other than the default connections presented below, see section
I/O terminals on page 49.
Note: Parameter 2108 START INHIBIT must remain in the default setting 0 (OFF).
