SIEPYEUOQ2A01G AC Drive Q2A Technical Manual 569
When the MFDI terminal set to PID Disable [H1-xx = 6A] activates, the drive disables fault detection.
4 : AL+DO@PID Enable
The drive detects FbL and FbH . The MFDO terminal set for PID Feedback Low or PID Feedback High activates.
The output terminal set for Alarm [H2-01 to H2-03 = 4] activates and the drive continues operation.
When the MFDI terminal set to PID Disable [H1-xx = 6A] activates, the drive disables fault detection.
5 : FLT+DO@PID Enable
The drive detects FbL and FbH . The output terminal set for Fault [H2-01 to H2-03 = 3] activates and the motor
coasts to stop.
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] .

(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] .
