2.14 Y: Application Features
Note:
• The unit, decimal place, and setting range change when the Y1-07 [Minimum Speed Units] setting changes:
–Y1-07 = 0 [Hz]: The setting range is 0.0 Hz to E1-04 Hz.
–Y1-07 = 1 [RPM]: The setting range is 0 RPM to (E1-04 × 60) RPM.
• When A1-02 = 8 [Control Method Selection = EZ Vector Control], the range is 0.0 Hz to (E9-02 × 2) Hz.

RUN
Note:
• Set Y1-10 = 0 [Low Feedback Selection = Fault (and Digital Output)] to enable this parameter.
• When Y1-01 = 3 [Multiplex Mode = Memobus Network], Y9-18 [Staging Mode] uses this value to calculate the quick de-stage feedback
level.

Y1-10 Low Feedback Selection
(3C09)
The drive enables the Low Feedback detection when:
• Parameter Y1-08 > 0.0
• Drive is running in AUTO Mode, including sleep boost and feedback drop detection (b5-09 = 0 [PID Output Level
Selection = Normal Output (Direct Acting)])
• There is a Run command, including sleep and timer operation (b5-09 = 1 [Reverse Output (Reverse Acting)])
0 : Fault (and Digital Output)
The keypad will show LFB [Low Feedback Sensed] and the motor coasts to stop. The output terminal set for H2-xx =
97 [MFDO Function Selection = Low Feedback] will activate.
To deactivate the digital output, do a Fault Reset.

V/f OLV/PM EZOLV OLV/PM
Sets the units and decimal place for Y1-06 [Minimum Speed].
V/f OLV/PM OLV/PM EZOLV
Sets the lower detection level for the PID feedback.
V/f OLV/PM OLV/PM EZOLV
Sets the delay time for the drive to detect an LFB [Low Feedback Sensed] fault after the feedback
level decreases to less than the value set in Y1-08 [Low Feedback Level].
V/f OLV/PM EZOLV OLV/PM
Sets the drive response when the feedback decreases to less than Y1-08 [Low Feedback Level] for
longer than the time set in Y1-09 [Low Feedback Lvl Fault Dly Time].
