YASKAWA SIEPC71061737B GA800 Drive Technical Reference 695
4 : Alarm + Digital Out, @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 = 10] activates and the drive continues operation.
When the MFDI terminal set to PID Disable [H1-xx = 19] activates, the drive disables fault detection.
5 : Fault + Digital Out, @PID Enable
The drive detects FbL and FbH . Fault relay output terminal MA-MC activates, MB-MC turns OFF, and the drive
coasts to stop.
When the MFDI terminal set to PID Disable [H1-xx = 19] activates, the drive disables fault detection.

PID Feedback Loss
Detection Lvl
Sets the level that triggers PID Feedback Loss [FbL] detection as a percentage of the 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] .

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] .

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 .

RUN
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] .
