Applies a gain to the PID output and can help when
b5-01 = 3 or 4 [PID Mode Setting = Fref + PID Trim, Fref +
PID Trim (D on feedback)]
.

b5-11
(01AF)
PID Output Reverse
Selection
Sets the function that enables and disables reverse motor rotation for negative PID control output.
0
(0, 1)
This parameter is disabled when
b5-01 = 3, 4 [PID Mode Setting = Fref + PID Trim, Fref + PID Trim (D on
feedback)]
. There is no limit for PID output (PID output can be positive or negative). Operates the same as setting
“
1:
Enabled: Negative lower limit
”
.
0 : Lower Limit is Zero
When PID output is negative, PID output is limited to 0 and drive output is shut off.
1 : Negative Output Accepted
When the PID output is negative, the motor will rotate in reverse. When
b1-04 = 1 [Reverse Operation Selection =
Reverse Disabled]
, the lower limit is 0.

b5-12: Feedback Loss Detection Select
No.

Description
Default

b5-12
(01B0)
Feedback Loss Detection
Select
Sets the drive response to PID Feedback Low/High. Sets drive operation after the drive detects PID
feedback Low/High.
0
(0 - 5)
0 : Digital Out Only, Always Detect
The MFDO terminal set for
PID Feedback Low
or
PID Feedback High [H2-01 to H2-03 = 3E, 3F]
activates. When
the drive detects Feedback Low/High, the keypad will not show a minor fault/alarm and the drive will continue
operation.
When the feedback signal is less than the level set in
b5-13 [PID Feedback Loss Detection Lvl]
for longer than the
time set in
b5-14 [PID Feedback Loss Detection Time]
, the MFDO terminal set for a
PID Feedback Low
activates.
When the feedback signal is more than the level set in
b5-36 [PID High Feedback Detection Lvl]
for longer than the
time set in
b5-37 [PID High Feedback Detection Time]
the MFDO terminal set for a
PID Feedback High
activates.
When the feedback value is not in the detection range, the drive resets the MFDO.
1 : Alarm + Digital Out, Always Det
The drive detects
FbL [PID Feedback Loss]
and
FbH [Excessive PID Feedback]
. The MFDO terminal set for
PID
Feedback Low
or
PID Feedback High [H2-01 to H2-03 = 3E, 3F]
activates. The output terminal set for
Alarm [H2-
01 to H2-03 = 10]
activates and the drive continues operation.
When the feedback signal is less than the level set in
b5-13
for longer than the time set in
b5-14
, the MFDO terminal
set for a
PID Feedback Low
activates.
When the feedback signal is less than the level set in
b5-36
for longer than the time set in
b5-37
, the MFDO terminal
set for a
PID Feedback High
activates.
When the feedback value is not in the detection range, the drive resets the MFDO.
2 : Fault + Digital Out, Always Det
The drive detects
FbL
and
FbH
. Fault relay output terminal MA-MC activates, MB-MC turns OFF, and the motor
coasts to stop.
When the feedback signal is less than the level set in
b5-13
for the time set in
b5-14
, the drive detects
FbL
.
When the feedback signal is less than the level set in
b5-36
for the time set in
b5-37
, the drive detects
FbH
.
3 : Digital Out Only, @ PID Enable
The MFDO terminal set for
PID Feedback Low
or
PID Feedback High
activates. The keypad will not show a minor
fault/alarm. The drive continues operation.
When the MFDI terminal set to
PID Disable [H1-xx = 19]
activates, the drive disables fault detection.
