• When the Up 2 is enabled, drive
accelerates up to the frequency
reference plus d4-03 (bias is
increased for d4-03).
• When Down 2 is enabled, drive
decelerates down to the frequency
reference minus d4-03 (bias is
decreased for d4-03).
• Holds output frequency (holds the
bias) when no Up 2 or Down 2 input
or both active.
• Resets the bias when the reference
changes
• Operates with the frequency
reference in all other situations.

If the bias and frequency
reference are constant for 5 s,
the bias is added to the active
frequency reference and reset
afterwards.

• Accelerates (increases the bias) while
the Up 2 function is closed
• Decelerates (decreases the bias)
while Down 2 is closed
• Holds output frequency (holds the
bias) when no Up 2 or Down 2 input
or both active.
• When during accel/decel. the
frequency reference changes for
more then d4-07, bias value is held
until the output frequency meets the
reference (speed agree).

If the bias is constant for 5 s, is
is saved to parameter d4-06.
The frequency reference cannot
be overwritten, so only the bias
is saved.
