• Up/Down
The frequency reference value will be saved when the Run command or the drive power is switched off. The drive will use
the frequency reference that was saved when it restarts.
• Up/Down 2 with Frequency Reference from Digital Operator
When the digital operator is selected as the frequency reference source, the bias will be added to the frequency reference
that was selected 5 s after the Up/Down 2 command has been released, and then reset to 0 afterwards. The new frequency
reference value is then saved. When the Run command or the power supply is switched off, the drive will use the value that
was when it restarts.

• Up/Down 2 with Frequency Reference from Other Input Sources
When the frequency reference is set by an another source than the digital operator, the bias value will be saved in parameter
d4-06 exactly 5 s after the Up/Down 2 command has been released. When the Run command is turned off or the power is
switched off, the drive will use the value saved in d4-06 when it restarts.
