8.1.6 AP2-45 Damper Operation
A damper is a device that controls the flow in a ventilation system. If a damper is used in a system,
the inverter may be configured to operate according to the damper’s operation status. One of the
digital input terminals (IN-65–71) may be set to ‘45 (Damper Open)’ to receive the damper open
status input. During a damper operation, one of the relay outputs OUT-31–35 (Relay 1–5) may
also be set to ‘33 (Damper Control)’ to output a signal based on the damper’s operation status.
The inverter starts operating when both the run command and the damper open signal are
activated. A relay output setting at OUT- 31~35 is not necessary.
When the time difference between the inverter run command and the damper open signal
exceeds the delay time set at AP2-45 (Damper DT), damper error (Damper Err) occurs. If the
damper open relay output and damper control input are set at the same time, and if the damper
open signal is not received until the time set at AP2-45 (Damper DT) is elapsed (when the inverter
is not operating), damper error (Damper Err) occurs.

Description
AP2-45
Damper DT
Sets the damper open delay time. Detects the inverter run command or the
damper open signal (whichever is received first) and outputs a damper error
(Damper Err) if the other signal is not received until the time set at AP2-45
elapses.
IN-65~71
P1–P7 define
Sets one of the multi-functional terminals to ’45 (Damper Open)’ to
enable damper operation.
OUT-31–35
Relay 1–5
Sets one of the relay outputs to ’33 (Damper Control)’ to provide a
relay output when the inverter run command is turned on.
Note
Damper operation is one of the essential system features that are available in both HAND and
AUTO modes.
