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 Accel/Decel Ramp Hold [H1-xx = A].
• 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.
■
d4-03: Up/Down 2 Bias Step Frequency
No.
Name
(Hex.)
d4-03 Up/Down 2 Bias Step
Frequency
(02AA)
RUN
The operation is different for different setting values:
• Setting d4-03 = 0.00 Hz
When the Up/Down 2 Command [H1-xx = 75, 76] is active, the drive uses the accel/decel times set in d4-04
[Up/Down 2 Ramp Selection] to increase or decrease the bias value.
• Setting d4-03 ≠ 0.00 Hz
When the Up/Down 2 Command [H1-xx = 75, 76] 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.

d4-04: Up/Down 2 Ramp Selection
No.

RUN
0 : Use Selected Accel/Decel Time
Use the active acceleration and deceleration times to increase or decrease the bias.
1 : Use Accel/Decel Time 4
Use C1-07 [Acceleration Time 4] and C1-08 [Deceleration Time 4] to increase or decrease the bias.
