Note:
To use the combination of the frequency reference hold function and the Up/Down 2 function, configure the Up/Down 2 upper limit
[d4-08] and lower limit [d4-09] correctly.
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.

Up/Down 2 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 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.
Figure 12.68 Up/Down 2 Bias when d4-03 = 0.00 Hz
• 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.
