7.10.2.2
Maximum output voltage fan control
Options:
0…10
This parameter indicates the maximum output voltage used to control the fan. This voltage oper-
ates the fan at its highest speed.
Note
The minimum output voltage may not exceed the maximum.
Note
Please comply with the technical data for the fan.
7.10.2.3
Enable start-up behavior (switch on from Off to On)
Options:
No
Yes
This parameter enables the fan to start from the OFF state at a defined speed. This fan speed is
immediately applied.
•
Yes
: This displays the dependent parameters
Switch on at speed
and
Minimum dwell time at

.
To guarantee that the fan motor starts up reliably, it can be useful to start it at a higher fan speed
initially to increase the torque during start-up.
Note
The dwell times, which are taken into account in automatic operation, are inactive and will only be
taken into account after the start-up phase.
Note
The start-up behavior is a technical characteristic of the fan. For this reason, this behavior has a
higher priority than an active limitation or forced operation.
Note
Forced operation remains valid and is taken into account.
If an Off command is received during start-up, the fan switches off immediately regardless of
whether the required time at start-up speed has elapsed.
7.10.2.3.1
—
Dependent Parameter
Switch on at speed
Options:
0…30…100
This setting determines the speed at which the fan starts from the OFF state.
7.10.2.3.2
—
Dependent Parameter
Minimum dwell period in switch on speed
Options:
0…5…600
This parameter defines the minimum dwell time for one of the switch on speeds.
