Y4-12: Thrust Frequency
No.
(Hex.)
Name
Description
Default
(Range)
Y4-12
(3D05)
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)
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.

Y4-13: Thrust Deceleration Time
No.
(Hex.)
Name
Description
Default
(Range)
Y4-13
(3D06)
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)
When
Y4-13 > 0.0
, the drive will decelerate from the
Y4-12
value to zero in exactly the
Y4-13
time.
When
Y4-13 = 0
, the drive will use the standard deceleration rate.

Y4-18: Differential Level
No.

(Range)
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.
0.00%
(-99.99 - +99.99%)
Note:
•
The drive will respond based on 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.
