RUN
Maximum Setpoint
Difference
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].
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.

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.
Note:
Set Y1-15 = 0 [Maximum Setpoint Difference = 0] to disable this function.

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].

RUN
Prime Loss Time Sets the delay time before the drive detects an LOP [Loss of Prime] condition. The timer
starts when the drive detects the conditions in Y1-18 [Prime Loss Detection Method] and
Y1-19 [Prime Loss Level].

Sleep Level Type Sets the data source that the drive uses to know when to activate the Sleep Function.
0 : Output Frequency
1 : Output Current
2 : Feedback

Note:
• Feedback depends on PID direction operation.
• When the Sleep Function is active, the keypad will show the “Sleep” Alarm.

RUN
Sleep Level Sets the level that the level type set in Y2-01 [Sleep Level Type] must be at for the time set
in Y2-03 [Sleep Delay Time] for the drive to enter Sleep Mode.
Note:
• When you set this parameter to 0.0, this function will not be active.
• This function is active only when the drive operates in AUTO Mode.
• When Y2-01 = 5 [Output Frequency (non-PID)], the drive will disable the Sleep
function when you set this parameter to 0.0.
• When Y2-01 ≠ 5, the drive will set the sleep level to the largest value from d2-02
[Frequency Reference Lower Limit], Y1-06 [Minimum Speed], and Y4-12 [Thrust
Frequency] when you set this parameter to 0.0.
