Damper control
This function applies to the ventilation ducts. The aim is to control the opening of the duct (shutter device called
a "damper") when the fan starts up.
Damper opening command
The opening command can be assigned to a relay via the F130 or F132 parameters to the function
[Damper] 68 or [Inv. damper] 69 page 103
. The damper is closed automatically when there is no longer an
opening command.
Damper opening feedback
Opening is controlled by a bit or a logic input that can be assigned via the F111 or F112 or F113
parameters to the function [Damper feedBack] 73 page 96
. The corresponding logic input or bit can be
configured via the parameter [Damper fdb type] F580.
When there is an inconsistency, the drive goes on a [Damper fault 1] Fd1 if the damper does not open and on
a [Damper fault 2] Fd2 if it does not close.
The parameter [Time open damper] F581 can be used to delay tripping on an opening fault when a run
command is sent and the parameter [Time close damper] F582 delays the closing fault when a stop command
is sent.
