d4-01
(0298)
Freq Reference Hold
Selection
Sets the function that saves the frequency reference or the frequency bias (Up/Down 2) after a Stop
command or when de-energizing the drive.
Set H1-xx [MFDI Function Selection] to one of these values to enable this parameter:
• A [Accel/Decel Ramp Hold]
• 10/11 [Up/Down Command]
• 75/76 [Up/Down 2 Command]
0 : Disabled
1 : Enabled
0

d4-03
(02AA)
RUN
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)
d4-04
(02AB)
RUN
Up/Down 2 Ramp Selection
Sets the acceleration and deceleration times for the Up/Down 2 function to apply the bias to the
frequency reference.
0 : Use Selected Accel/Decel Time
1 : Use Accel/Decel Time 4
0
(0, 1)
d4-05
(02AC)
RUN
Up/Down 2 Bias Mode
Selection
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.
0 : Hold when Neither Up/Down Closed
1 : Reset when Neither / Both Closed
0
(0, 1)
d4-06
(02AD)
Frequency Ref Bias (Up/
Down 2)
Saves the bias value from the Up/Down 2 Command where the Maximum Output Frequency is
100%.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
0.0%
(-99.9 - +100.0%)
d4-07
(02AE)
RUN
Analog Freq Ref Fluctuate
Limit
If the frequency reference changes for more than the level set to this parameter, then the bias value
will be held. The value is set as a percentage of the Maximum Output Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
1.0%
(0.1 - 100.0%)
d4-08
(02AF)
RUN
Up/Down 2 Bias Upper
Limit
Sets the upper limit of the Up/Down 2 bias as a percentage of the Maximum Output Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
100.0%
