Remove the Saved Frequency Reference Value
The procedure to remove the saved frequency reference value is different for different functions. Use these
methods to remove the value:
•
Release the input programmed for Ac/Dec Hold [H1-xx = 17] .
•
Set an Up or Down command while no Run command is active.
•
Use the Up/Down 2 Command to set d4-06 = 0.0 or set d4-06 = 0.0 during stop.

Up/Dw2 Bias Step
Frequency
Sets the bias that the Up/Down 2 function adds to or subtracts from the frequency reference.
0.00 Hz
(0.00 - 99.99 Hz)
The operation is different for different setting values:
•
Setting d4-03 = 0.00 Hz
When H1-xx = 65, 66 [Up2 Command, Dw2 Command] is active, the drive uses the accel/decel times set in d4-
04 [Up/Dw2 Ramp Selection] to increase or decrease the bias value.
Figure 12.60 Up/Down 2 Bias when d4-03 = 0.00 Hz
•
Setting d4-03 ≠ 0.00 Hz
When the H1-xx = 65, 66 [Up2 Command, Dw2 Command] is active, the drive increases or decreases the bias
in steps for the value set in d4-03 . The drive uses the acceleration and deceleration times set in d4-04 .

(02AB)
RUN
Up/Dw2 Ramp Selection
Sets the acceleration and deceleration times for the Up/Down 2 function to apply the bias to the
frequency reference.
0
(0, 1)
0 : Current Ac/Dec Time
Use the active acceleration and deceleration times to increase or decrease the bias.
1 : Ac/Dec 4
Use C1-07 [Accel Time 4] and C1-08 [Decel Time 4] to increase or decrease the bias.
