RUN
Thrust Frequency Sets the Thrust Frequency that the drive will use to know which acceleration and
deceleration time to use. The drive will accelerate to this frequency in the Y4-11 [Thrust
Acceleration Time] time and decelerate from this frequency in the Y4-13 [Thrust
Deceleration Time] time.
0.0 Hz
(0.0 - 400.0 Hz)

RUN
Thrust Deceleration Time Sets the length of time necessary for the drive to go from the Thrust Frequency in Y4-12
[Thrust Frequency] to stop when Thrust Mode is active.
5.0 s
(0.0 - 600.0 s)

Y4-18
(3D0B)
RUN
Differential Level Sets the maximum difference that the drive will allow when it subtracts the Differential
Feedback from the Primary PID Feedback.
Note:
• The drive will respond as specified by the setting in Y4-20 [Differential Level
Detection Selection] when the difference increases to more than the value set in this
parameter for the time set in Y4-19 [Differential Level Detection Time].
• Set this parameter to 0.00 to disable Differential Feedback Detection.

RUN
Differential Lvl Detection
Time
Sets the length of time that the difference between PID Feedback and the Differential
Feedback must be more than Y4-18 [Differential Level] before the drive will respond as
specified by Y4-20 [Differential Level Detection Selection].

RUN
Low City Off-Delay Time Sets the length of time that the drive will wait to start again after you clear a Low City
Pressure condition.

RUN
Low City Alarm Text Sets the alarm message to show on the keypad when the drive detects a Low City Pressure
condition.

Diff Lvl Src Fdbk Backup
Select
Sets the function to enable or disable Differential Level Source [H3-xx = 2D] as the
backup transducer if there is a failure with the primary PID Feedback transducer [H3-xx =
B] and the PID Feedback Backup transducer [H3-xx = 24] is not available.
