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 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.
