1 Enabled: Starts the motor from the last frequency reference the drive was given before the power was shut off.
Note:
Enabled when the multi-function inputs are assigned for “Accel/Decel Ramp Hold” or "Up/Down" (H1-oo = A or 10 and 11). When d4-01 = 1, the drive will save the
frequency reference if the power goes out and then start back up and at that frequency reference as soon as the next Run command is entered. When d4-01 = 1 when the drive
is shut off, it will save the frequency reference at that time, then accelerate back up to that frequency the next time the drive is turned back on and a new Run command is
issued. To clear the frequency reference that was saved, an Up command or Down command must be entered while the Run command is still off. When d4-01 = 1, the drive
will accelerate up to the Up 2 or Down 2 Hold Frequency that was saved befeore the power supply was interrupted the next time the Run command is entered. To reset this
frequency, enter a new UP 2 or Down 2 reference while the Run command is still off. Both the Up/Down and Up 2 / Down 2 commands cannot be assigned to the multi-
function input terminals at the same time. Doing so will trigger an oPE03 error, which indicates a contradiction set to the multi-function terminals. The drive will no longer be
able to decelerate the motor if a Accel/Decel Ramp Hold command is entered during deceleration.

d4-03: Frequency Reference Bias Step (Up/Down 2)
Sets the amount to add or subtract from the frequency reference.
No. Parameter Name Setting Range Default
d4-03 Frequency Reference Bias Step (Up/Down 2) 0.00 to 99.99 0.00 Hz
Detailed Description
d4-03 = 0.00
While the Up 2 or Down 2 command is enabled, the bias set to d4-04 will be added (or subtracted) to the frequency reference. Here, the accel/decel times
set to the C1 parameters are disregarded.
If d4-03 is set to any value higher than 0.00:
While the terminal assigned to Up 2 or Down 2 is closed, the value set to d4-03 will be added to the speed. After five seconds, the bias value is added (or
subtracted) to the frequency reference. This new frequency reference is kept even after the Up 2 or Down 2 command is released. Parameter d4-04
determines the rate at which the drive accelerates or decelerates after the Up 2 or Down 2 command has been added to the frequency reference.
Note: To add a positive bias, when the Up 2 command is enabled (i.e., the switch is closed), it is added to the acceleration rate.
To add a negative bias:

Note: Down 2 is enabled as long as the terminal to which it is assigned is closed. During this time, the value set for Down 2 will be added to the deceleration rate.

d4-04: Frequency Reference Accel/Decel(Up/Down 2)
Determines the bias added to the acceleration and deceleration times.
No. Parameter Name Setting Range Default
d4-04 Frequency Reference Accel/Decel (Up/Down 2) 0, 1 0
Detailed Description
0 Adjusts the bias value according to the currently select accel/decel time.
1 Adjusts the bias value by Accel/Decel Time 4 (C1-07 and C1-08).
n
d4-05: Frequency Reference Bias Operation Mode Selection (Up/Down 2)
Determines the frequency reference bias operation when d4-03 is set to 0.00.
No. Parameter Name Setting Range Default
d4-05 Frequency Reference Bias Operation Mode Selection (Up/Down 2) 0, 1 0
Detailed Description
0 Holds the bias value when Up/Down 2 reference is on or off.
