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.

RUN
The operation is different for different setting values:
• Setting d4-03 = 0.00 Hz
When H1-xx = 65, 66 [d4-03: Up2 Command, d4-03: Dw2 Command] is active, the drive uses the accel/decel
times set in d4-04 [d4-03: Up/Dw2 Ramp Selection] to increase or decrease the bias value.
• Setting d4-03 ≠ 0.00 Hz
When H1-xx = 65, 66 [d4-03: Up2 Command, d4-03: 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.

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.

Sets the acceleration and deceleration times for the Up/Down 2 function to apply the bias to the
frequency reference.
