2.14 Y: Application Features
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.
■
Y1-14: Feedback Hysteresis Level
No.
Name
(Hex.)
Y1-14 Feedback Hysteresis Level
(3C0D)
RUN
Note:
Unit and decimal place change when the system units change.
■
Y1-15: Maximum Setpoint Difference
No.
Name
(Hex.)
Y1-15 Maximum Setpoint
Difference
(3C0E)
RUN
Note:
• Unit and decimal place change when the system units change.
• If there is a fault, the drive will coast to a stop.
• Set this parameter to 0.0 to disable the function.
• This function is only active during run when in Auto Mode.
• When Y1-01 = 3 [Multiplex Mode = Memobus Network], the function is active on the lead drive, but will stop all drives running on the
network if there is an NMS [Setpoint Not Met] fault (system fault).
■
Y1-16: Not Maintaining Setpoint Time
No.
Name
(Hex.)
Y1-16 Not Maintaining Setpoint
Time
(3C0F)
RUN
Note:
Set Y1-15 = 0 [Maximum Setpoint Difference = 0] to disable this function.
■
Y1-17: Not Maintaining Setpoint Sel
No.
Name
(Hex.)
Y1-17 Not Maintaining Setpoint Sel
(3C10)
The drive enables the Not Maintaining Set Point detection when:
• Drive is operating in PID control (b5-01 ≠ 0 [PID Mode Setting ≠ Disabled)
• Drive is operating in AUTO Mode
• Drive is not in Pre-Charge Mode
• Drive is not in the sleep state
• Drive is not in stabilization delay condition after staging or de-staging while in MEMOBUS multiplex Mode
• Parameter Y1-15 > 0 [Maximum Setpoint Difference > 0]
0 : Fault (and Digital Output)
The keypad will show an NMS [Setpoint Not Met] fault and the motor coasts to stop. The output terminal set for H2-
xx = AC [Setpoint Not Maintained] will activate.
To deactivate the digital output, do a Fault Reset.

V/f OLV/PM OLV/PM EZOLV
Sets the hysteresis level for low and high level feedback detection.
V/f OLV/PM OLV/PM EZOLV
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].
V/f OLV/PM OLV/PM EZOLV
Sets the delay time before a Setpoint Not Met condition occurs. The drive must detect the setpoint
difference set in Y1-15 [Maximum Setpoint Difference] before the timer will start.
V/f OLV/PM EZOLV OLV/PM
Sets the drive response when the feedback increases to more or decreases to less than the setpoint for
more than the amount set in Y1-15 [Maximum Setpoint Difference].
