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 Select] to one of the these values to
operate this parameter:
• A [Accel/Decel Ramp Hold]
• 10/11 [Up/Down Command]
• 75/76 [Up/Down 2 Command]

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.
