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.

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.

0 : Hold when Neither Up/Down Closed
When the two MFDI terminals set for Up/Down 2 Command [H1-xx = 75, 76] activate or deactivate, the drive will
hold the bias value.
1 : Reset when Neither / Both Closed

V/f CL-V/f OLV CLV AOLV
Sets the acceleration and deceleration times for the Up/Down 2 function to apply the bias to the
frequency reference.
V/f CL-V/f OLV CLV AOLV
Sets the function that saves the bias value to the drive when you open or close the two Up/Down 2
Commands [H1-xx = 75, 76]. Set d4-03 [Up/Down 2 Bias Step Frequency] = 0.00 before you set this
parameter.
