RUN
■
Y4-03: Pre-Charge Time
No.

Y4-03 Pre-Charge Time
(3CFC)
RUN
Note:
• Set this parameter to 0.0 to disable the function.
• When Y1-01 = 3 [Multiplex Mode = Memobus Network], the function is active only on the first drive to run in the network.

Y4-05: Pre-Charge Loss of Prime Level
No.

RUN
■
Y4-11: Thrust Acceleration Time
No.
Name
(Hex.)
Y4-11 Thrust Acceleration Time
(3D04)
RUN
When Y4-11 = 0, the drive will use the standard acceleration rate.
■
Y4-12: Thrust Frequency
No.
Name
(Hex.)
Y4-12 Thrust Frequency
(3D05)
RUN
WARNING! Sudden Movement Hazard. When you set Thrust Frequency, do not re-energize the drive while you enter the Run
command. If you de-energized the drive while it is running, the drive can automatically start when you energize it and it can cause
serious injury or death.
At start, the drive will use the Y4-11 [Thrust Acceleration Time] time until the output frequency increases to Y4-12.
During the Y4-11 time, the terminal set for H2-xx = AB [MFDO Function Selection = Thrust Mode] will be active.
When the output frequency is at or more than Y4-12, the drive will use the active acceleration and deceleration times
set in C1-01 [Acceleration Time 1] to C1-04 [Deceleration Time 2]. At stop, when the output frequency decreases to
Y4-12, the drive will use Y4-13 [Thrust Deceleration Time] for the remaining deceleration time.
Figure 2.116 shows an example of drive operation during Thrust mode when b1-03 = 0 [Stopping Method Selection =
Ramp to Stop].

V/f OLV/PM EZOLV OLV/PM
Sets the frequency at which the pre-charge function will operate.
V/f OLV/PM OLV/PM EZOLV
Sets the length of time that the Pre-Charge function will run.
V/f OLV/PM OLV/PM EZOLV
Sets the level at which the drive will detect loss of prime in the pump.
V/f OLV/PM EZOLV OLV/PM
Sets the time at which the drive output frequency will ramp up to the reference frequency set in Y4-
12 [Thrust Frequency].
V/f OLV/PM EZOLV OLV/PM
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.
