Function
Description
3A
Drive Overheat Alarm
The terminal activates when the drive heatsink temperature is at the
L8-02 [Overheat Alarm Level]
setting while
L8-03 = 4
[Overheat Pre-Alarm Selection = Operate at Reduced Speed (L8-19)]
and the drive is running.
The drive will decrease the frequency reference as specified by
L8-19 [Freq Reduction @ oH Pre-Alarm]
. Carrier
frequency reduction is active when
L8-97 = 1 [Carrier Freq Reduce during OH = Enabled]
.

3D: During Speed Search
Setting Value
Function
Description
3D
During Speed Search

42: Pressure Reached
Setting Value
Function
Description
42
Pressure Reached
The terminal activates when the drive is at the Pressure Setpoint.
The drive uses the Pressure Feedback and
Y4-36 [Pressure Reached Exit Conditions]
to
Y4-40 [Pressure Reached
Detection Sel]
for the activation and deactivation conditions.
When the
b5-09 [PID Output Level Selection]
setting changes, the MFDO terminal operation also changes.
•
When
b5-09 = 0 [Normal Output (Direct Acting)]
The function activates when the feedback is at or above the setpoint for the time set in
Y4-38 [Pressure Reached On
Delay Time]
.
•
When
b5-09 = 1 [Reverse Output (Reverse Acting)]
The function activates when the feedback is at or below the setpoint for the time set in
Y4-38
.
When this function activates, it will use
Y4-36
,
Y4-37 [Pressure Reached Hysteresis Lvl]
, and
Y4-39 [Pressure
Reached Off Delay Time]
to deactivate.
■
4C: During Fast Stop
Setting Value
Function
Description
4C
During Fast Stop
The terminal activates when the fast stop is in operation.
■
4D: oH Pre-Alarm Reduction Limit
Setting Value
Function
Description
4D
oH Pre-Alarm Reduction
Limit
The terminal activates when
L8-03 = 4 [Overheat Pre-Alarm Selection = Operate at Reduced Speed (L8-19)]
and
oH [Heatsink
Overheat]
does not clear after the drive decreases the frequency for 10 cycles.
Note:
Refer to
“
L8-03: Overheat Pre-Alarm Selection
”
for more information.
