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 (parameter 3-51 Ramp 2 Ramp Up
Time 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 [8]
Start 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 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.
