YASKAWA SIEPC71061737D GA800 Drive Technical Reference 753
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 less than the level set in b5-36 for the time set in b5-37, the drive detects FbH.
3 : Digital Out Only, @ PID Enable
The MFDO terminal set for PID Feedback Low or PID Feedback High activates. The keypad will not show a minor
fault/alarm. The drive continues operation.
When the MFDI terminal set to PID Disable [H1-xx = 19] activates, the drive disables fault detection.
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].
■ b5-14: PID Feedback Loss Detection Time

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.
