Shifts between external reference and preset
reference. It is assumed that [1] External/preset
has been selected in 3-04 Reference Function.
Logic '0' = external reference active; logic '1' =
one of the 8 preset references is active.
Preset ref. bit 0,1, and 2 enables a choice
between one of the 8 preset references
according to Table 4.2.

Freezes the actual reference, which is now the
point of enable/condition for [21] Speed up and
[22] Speed down to be used. If [21] Speed up or [22]
Speed down is used, the speed change always
follows ramp 2 (3-51 Ramp 2 Ramp Up Time and
parameter 3-52 Ramp 2 Ramp Down Time) in the
range 0 - 3-03 Maximum Reference.
Freezes the actual motor frequency (Hz), which is
now the point of enable/condition for [21] Speed
up and [22] Speed down to be used. If [21] Speed up
or [22] Speed down is used, the speed change
always follows ramp 2 (3-51 Ramp 2 Ramp Up Time
and parameter 3-52 Ramp 2 Ramp Down Time) in
the range 0 - 1-23 Motor Frequency.
NOTICE
When Freeze output is active, the frequency
converter cannot be stopped via a low 'start
[8]' signal. Stop the frequency converter via
a terminal programmed for [2] Coasting
inverse or [3] Coast and reset, inverse.
Select [21] Speed up and [22] Speed down if digital
control of the up/down speed is desired (motor
potentiometer). Activate this function by selecting
either [19] Freeze reference or [20] Freeze output.
When speed up/down is activated for less than 400
ms, the resulting reference is increased/ decreased
by 0.1 %. If speed up/down is activated for more
than 400 ms, the resulting reference follows the
setting in ramping up/down parameter 3-x1/ 3-x2.

This function makes it possible to give an
external fault to the frequency converter. This
fault is treated in the same way as an internally
generated alarm.
(Terminal 29 or 33 only) Input for increment
counting in the SLC counter.
(Terminal 29 or 33 only) Input for decrement
counting in the SLC counter.
Input for reset of counter A.
(Terminal 29 or 33 only) Input for increment
counting in the SLC counter.
(Terminal 29 or 33 only) Input for decrement
counting in the SLC counter.
Input for reset of counter B.
When enabled, it inverts the resulting error
from the process PID controller. Available only
if 1-00 Configuration Mode is set to [6] Surface
Winder or [7] Extended PID Speed OL.
When enabled, resets the I-part of the Process
PID controller. Equivalent to
parameter 7-40 Process PID I-part Reset.
