• Up/Down Command
The frequency reference value will be saved when the Run command is cleared or when the drive is de-
energized. The drive will use the saved value as the frequency reference when it restarts.
• Up/Down 2 Command with Frequency Reference from Keypad
When a Run command is active and the Up/Down 2 command is released for longer than 5 s, the Up/Down 2
bias value is added to the frequency reference and then reset to 0. The frequency reference value to which the
bias value was added is saved in the drive. This new frequency reference will be used to restart the drive after
the Run command is cleared or after the drive is de-energized.

• Up/Down 2 Command with Frequency Reference from Input Sources Other Than the Keypad
When a Run command is active and the Up/Down 2 command is released for longer than 5 s, the bias value will
be saved in d4-06 [Frequency Ref Bias (Up/Down 2)]. The frequency reference + d4-06 is saved to the drive as
a frequency reference value. This new frequency reference will be used to restart the drive after the Run
command is cleared or after the drive is de-energized.
