Y1-13 High Feedback Selection
(3C0C)
The drive enables the High Feedback detection when:
• Parameter Y1-11 > 0.0
• There is a Run command, including sleep and timer operation (b5-09 = 0 [PID Output Level Selection = Normal
Output (Direct Acting)])
• Drive is running in AUTO Mode, including feedback drop detection (b5-09 = 1 [Reverse Output (Reverse Acting)])
0 : Fault (and Digital Output)
The keypad will show HFB [High Feedback Sensed] and the motor coasts to stop. The output terminal set for H2-xx
= 96 [MFDO Function Selection = High Feedback] will activate.
To deactivate the digital output, do a Fault Reset.
1 : Alarm (and Digital Output)
The keypad will show HIFB [High Feedback Sensed] and the output terminal set for H2-xx = 96 will activate.
To deactivate the digital output and clear the alarm, decrease the feedback to be less than Y1-11 - Y1-14 [Feedback
Hysteresis Level], or make sure that one or more of the conditions that enable High Feedback detection are no longer
true.
2 : Digital Output Only
The output terminal set for H2-xx = 96 will activate.
To deactivate the digital output and clear the alarm, decrease the feedback to be less than Y1-11 - Y1-14, or make sure
that one or more of the conditions that enable High Feedback detection are no longer true.

YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Sets the delay time between when the drive detects high feedback until the drive faults on an HFB
[High Feedback Sensed] fault.
Sets the drive response when the feedback increased to more than Y1-11 [High Feedback Level] for
longer than the time set in Y1-12 [High Feedback Lvl Fault Dly Time].
Sets the hysteresis level for low and high level feedback detection.
Sets a percentage of difference between the setpoint and the feedback. The difference must be more
than this value for the time set in Y1-16 [Not Maintaining Setpoint Time] to trigger the drive response
set in Y1-17 [Not Maintaining Setpoint Sel].
