[20] Freeze
output
Freezes the actual motor frequency (Hz), which is
now the point of enable/condition to be used for
[21] Speed up
and
[22] Speed down
. If speed up/
speed down is used, the speed change always
follows ramp 2 (
and
parameter 3-52 Ramp 2 Ramp Down Time
)
in the range 0–
parameter 1-23 Motor Frequency
.
NOTICE
When freeze output is active, the frequency
converter cannot be stopped via a low

Start
signal. Stop the frequency converter
via a terminal programmed for
[2] Coasting
inverse
or
[3] Coast and reset inverse
.
[21] Speed
up
Select
[21] Speed up
and
[22] Speed down
for digital
control of the up/down speed (motor potenti-
ometer). Activate this function by selecting either
[19] Freeze ref
or
[20] Freeze output
. When speed
up/speed down is activated for less than 400 ms,
the resulting reference is increased/decreased by
0.1%. If speed up/speed down is activated for
more than 400 ms, the resulting reference follows
the setting in ramping up/down parameters 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.
