12.2 b: APPLICATION
SIEPYEUOQ2A01A AC Drive Q2A Technical Manual 549
When the MFDI terminal set to PID Disable [H1-xx = 6A] activates, the drive disables fault detection.
■ b5-13 Fdback Loss Lvl
No.
(Hex.)
Name Description
Default
(Range)
b5-13
(01B1)
Fdback Loss Lvl
Sets the level that triggers PID Feedback Loss [FbL] as a percentage of E1-04 [Max 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 [Fdback Loss Time].
■ b5-14 Fdback Loss Time
No.
(Hex.)
Name Description
Default
(Range)
b5-14
(01B2)
Fdback Loss Time
Sets the length of time that PID Feedback must be less than b5-13 [Fdback Loss Lvl] to detect
PID Feedback Loss [FbL].
1.0 s
(0.0 - 25.5 s)
■ b5-15 Sleep Start Level
No.
(Hex.)
Name Description
Default
(Range)
b5-15
(01B3)
Sleep 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 [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 Sleep Delay Time
No.
(Hex.)
Name Description
Default
(Range)
b5-16
(01B4)
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.
0.5 s
(0.0 - 6000.0 s)
The drive usually uses the acceleration and deceleration times set in C1: ACCEL / DECEL, 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 SS Cancel [H1-xx = 75].
■ b5-18 b5-19 PID SP Selection
No.
(Hex.)
Name Description
Default
(Range)
b5-18
(01DC)
b5-19 PID SP 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
The drive uses the value set in b5-19 as the PID setpoint.
