■ b5-13: PID Feedback Loss Detection Lvl
No.
(Hex.)
Name Description
Default
(Range)
b5-13
(01B1)
PID Feedback Loss
Detection Lvl
Sets the level that triggers PID Feedback Loss [FbL] as a percentage of E1-
04 [Maximum Output Frequency].
0%
(0 - 100%)
The drive detects PID Feedback Loss [FbL] when the feedback signal decreases to less than the level set in b5-13
for longer than the time set in b5-14 [PID Feedback Loss Detection Time].
■ b5-14: PID Feedback Loss Detection Time
No.
(Hex.)
Name Description
Default
(Range)
b5-14
(01B2)
PID Feedback Loss
Detection Time
Sets the length of time that PID Feedback must be less than b5-13 [PID
Feedback Loss Detection Lvl] to detect PID Feedback Loss [FbL].
1.0 s
(0.0 - 25.5 s)
■ b5-15: PID Sleep Function Start Level
No.
(Hex.)
Name Description
Default
(Range)
b5-15
(01B3)
PID Sleep Function
Start Level
Sets the output level that triggers the PID Sleep function.
Determined by A1-02
(0.0 - 590.0)
The drive goes into Sleep mode when the PID output or frequency reference is less than b5-15 for longer than the
time set to b5-16 [PID Sleep Delay Time]. The drive continues operation when the PID output or frequency
reference is more than b5-15 for longer than the time set to b5-16.
■ b5-16: PID Sleep Delay Time
No.
(Hex.)
Name Description
Default
(Range)
b5-16
(01B4)
PID Sleep Delay
Time
Sets a delay time to start or stop the PID Sleep function.
0.0 s
(0.0 - 25.5 s)
■ b5-17: PID Accel/Decel Time
No.
(Hex.)
Name Description
Default
(Range)
b5-17
(01B5)
PID Accel/Decel
Time
Raises or lowers the PID setpoint using the acceleration and deceleration
times set to the drive. This is a soft-starter for the PID setpoint.
0.0 s
(0.0 - 6000.0 s)
The drive usually uses the acceleration and deceleration times set in C1-xx [Accel and Decel Times], but when
PID control is enabled, the drive applies C1-xx after PID output. If you frequently change the PID setpoint, the
drive responsiveness decreases. When resonance with PID control causes hunting, overshoot, or undershoot, set
b5-17 for longer acceleration and deceleration times.
Decrease C1-xx until hunting stops, then use b5-17 to check the acceleration and deceleration. To enable and
disable the setting in b5-17 through an MFDI terminal, set PID Soft Starter Disable [H1-xx = 34].
■ b5-18: b5-19 PID Setpoint Selection
No.
(Hex.)
Name Description
Default
(Range)
b5-18
(01DC)
b5-19 PID Setpoint
Selection
Sets the function that enables and disables b5-19 [PID Setpoint Value].
0
(0, 1)
0 : Disabled
The drive does not use the value set in b5-19 as the PID setpoint.
1 : Enabled
