Used for shifting between external reference and preset reference. It is
External/preset
assumed that
Function. Logic '0' = external reference active; logic '1' = one of the eight
preset references is active.
Enables a choice between one of the eight preset references according
to the table below.

Freezes actual reference. The frozen reference is now the point of enable/
condition for Speed up and Speed down to be used. If Speed up/down
is used, the speed change always follows ramp 2 (par.3-51
up Time and par.3-52 Ramp 2 Ramp down

erence/Feedb.).
Freezes actual motor frequency (Hz). The frozen motor frequency is now
the point of enable/condition for Speed up and Speed down to be used.
If Speed up/down is used, the speed change always follows ramp 2 (par.
3-51 Ramp 2 Ramp up Time

NOTE: When Freeze output is active, the frequency converter cannot be
stopped via a low 'start [13]' signal. Stop the frequency converter via a
terminal programmed for Coasting inverse [2] or Coast and reset, inverse
[3].
For digital control of the up/down speed is desired (motor potentiome-
ter). Activate this function by selecting either Freeze reference or Freeze
output. When Speed up is activated for less than 400 msec. the resulting
reference will be increased by 0.1 %. If Speed up is activated for more
than 400 msec. the resulting reference will ramp according to Ramp 1 in
par.3-41 Ramp 1 Ramp up
Same as Speed up [21].
Selects one of the four set-ups. Set par. 0-10 to Multi Set-up.
Same as Set-up select bit 0 [23].
(Default Digital input 32)
Select Pulse input when using a pulse sequence as either reference or
feedback. Scaling is done in par. group 5-5*.
Select which ramp to use. Logic "0" will select ramp 1 while logic "1"
will select ramp 2.
Select to activate function selected in par.14-10
failure is active in the Logic "0" situation.
