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.

Y1-17: Not Maintaining Setpoint Sel
No.

(Hex.)
Y1-17 Not Maintaining Setpoint Sel Sets the drive response when the feedback increases to more or decreases to less than the setpoint for
(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
• 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.
• If Not Maintaining Setpoint condition continues for longer than Y1-16 [Not Maintaining Setpoint Time] the drive
will detect an NMS fault.
• If the feedback increases or decreases to less than Y1-15 from the setpoint before Y1-16 expires, the drive will
deactivate the output terminal, clear the alarm, and reset Y1-16.
1 : Alarm (and Digital Output)
The keypad will show an NMS [Setpoint Not Met] alarm and the output terminal set for H2-xx = AC will activate.
To deactivate the digital output and clear the alarm, increase or decrease the feedback to less than Y1-15 from the
setpoint.
Note:
There is no time limit for this condition.
2 : Digital Output Only
The drive will detect Not Maintaining Setpoint and the output terminal set for H2-xx = AC will activate.
To deactivate the digital output, increase or decrease the feedback to less than Y1-15 from the setpoint.
Note:
There is no time limit for this condition.

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.
more than the amount set in Y1-15 [Maximum Setpoint Difference].
Sets the units and quantity that the drive will use to determine LOP [Loss of Prime].
