Freeze ref
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 (par. E-10 Ac-
cel
Time 2
and par. E-11 Decel
Time 2
) in the range 0 - par. F-53 Maximum
Reference
.
[20]
Freeze output
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
(par. E-10 Accel
Time 2
and par. E-11 Decel
Time 2
) in the range 0 - par. F-04 Base
Frequency
.
NB!
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.
[21]
Speed up
Select Speed up and Speed down if digital control of the up/down speed is desired (motor poten-
tiometer). 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 ramping up/ down parameter 3-x1/ 3-x2.

Precise stop inv.
Prolongs stop signal to give a precise stop independent of speed.
Sends an inverted stop signal when the precise stop function is activated in par. H-83 Precise

Precise stop inverse function is available for terminals 18 or 19.

Pulse input
Use pulse sequence as either reference or feedback. Scaling is done in par. group 5-5*.
