11.4.9 Pump/Fan Control [390]
The Pump Control functions are in menu [390]. The func-
tion is used to control a number of drives (pumps, fans, etc.)
of which one is always driven by the VSD.

pump control functions.
Communication information
Number of Drives [392]
Sets the total number of drives which are used, including the
Master VSD. The setting here depends on the parameter
Select Drive [393]. After the number of drives is chosen it is
important to set the relays for the pump control. If the dig-
ital inputs are also used for status feedback, these must be set
for the pump control.
