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]

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.

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]

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]

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]
