■ b5-10: PID Output Gain Setting
No.
(Hex.)
Name Description
Default
(Range)
b5-10
(01AE)
RUN
PID Output Gain Setting
Sets the amount of gain to apply to the PID output.
1.00
(0.00 - 25.00)
Applies a gain to the PID output and can help when b5-01 = 1 [PID Enable = Enabled] and b5-72 = 0 [PID D-
FF Mode = D=Fdback].
■ b5-11: PID Output Reverse Selection
No.
(Hex.)
Name Description
Default
(Range)
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 = 1 [PID Enable = Enabled] and b5-72 = 0 [PID D-FF Mode = D=
Fdback]. There is no limit for PID output (PID output can be positive or negative).
0 : 0 lower limit
When PID output is negative, PID output is limited to 0 and drive output is shut off.
1 : Negative lower limit
When the PID output is negative, the motor will rotate in reverse. When b1-04 = 1 [Reverse Operation Selection
= Disabled], the lower limit is 0.
■ b5-12: Fdback Loss Select Mode
No.
(Hex.)
Name Description
Default
(Range)
b5-12
(01B0)
Fdback Loss Select Mode
Sets the drive response to PID feedback loss/excess. Sets drive operation after the drive detects
PID feedback loss/excess.
0
(0 - 5)
0 : DO Only Always
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 loss/excess, the keypad will not show an alarm and the drive will continue
operation.
When the feedback signal is less than the level set in b5-13 [Fdback Loss Lvl] for longer than the time set in b5-
14 [Fdback Loss Time], the MFDO terminal set for PID Feedback Low activates.
When the feedback signal is more than the level set in b5-36 [PID HiHi Limit Level] for longer than the time set
in b5-37 [PID HiHi Time] the MFDO terminal set for PID Feedback High activates.
When the feedback value is not in the detection range, the drive resets the MFDO.
1 : AL+DO Always
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 = 4] 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 PID Feedback Low activates.
When the feedback signal is more than the level set in b5-36 for longer than the time set in b5-37, the MFDO
terminal set for PID Feedback High activates.
When the feedback value is not in the detection range, the drive resets the MFDO.
2 : FLT+DO Always
The drive detects FbL and FbH. MFDO terminal NO-CM turns ON, NC-CM 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 more than the level set in b5-36 for the time set in b5-37, the drive detects FbH.
3 : DO Only@PID Enable
The MFDO terminal set for PID Feedback Low or PID Feedback High activates. The keypad will not show an
alarm. The drive continues operation.
