(Range)
Y1-16
(3C0F)
RUN
Not Maintaining Setpoint
Time
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.
60 s

Note:
Set
Y1-15 = 0 [Maximum Setpoint Difference = 0]

Description
Default
(Range)
Y1-17

Not Maintaining Setpoint Sel 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].
0
(0 - 2)
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.
