Freezes the actual reference, which 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
(parameter E-10 Accel Time 2 and
parameter E-11 Decel Time 2) in the range 0 -
parameter F-53 Maximum Reference.
Freezes the actual motor frequency (Hz), which 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
(parameter E-10 Accel Time 2 and
parameter E-11 Decel Time 2) in the range 0 -
parameter F-04 Base 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 Coasting inverse
[2] or Coast and reset, inverse.
Select Speed up and Speed down if digital control
of the up/down speed is desired (motor potenti-
ometer). Activate this function by selecting either
Freeze reference or Freeze output. When Speed up/
down is activated for less than 400 msec. the
resulting reference will be increased/ decreased by
0.1 %. If Speed up/ down is activated for more
than 400 msec. the resulting reference will follow
the setting in accel/decel parameters.

Prolongs stop signal to give a precise stop
independent of speed.
Sends an inverted stop signal when the precise
stop function is activated in
parameter H-83 Precise Stop Function.
Precise stop inverse function is available for
terminals 18 or 19.
Use when Precise ramp stop [0] is selected in
parameter H-83 Precise Stop Function.
