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.
Clearing the Saved Freq Reference Value
The way to clear the saved frequency reference value varies depending on which function is combined. Clear the
values with any of the following methods.
• Releasing the input programmed for Accel/Decel Ramp Hold [H1-xx = A].
• Setting 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.

RUN
The operation depends on the set value:
• Setting d4-03 = 0.00 Hz
While Up/Down 2 Command [H1-xx = 75, 76] is ON, the bias value is increased or decreased using the accel/
decel times determined by d4-04 [Up/Down 2 Ramp Selection].
• Setting d4-03 ≠ 0.00 Hz
Every time Up/Down 2 Command [H1-xx = 75, 76] is switched ON, the bias is increased or decreased in steps
for the value set in d4-03. When the bias is increased or decreased, the acceleration and deceleration times set in
d4-04 are applied.
