Freezes actual reference. The frozen reference 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. 3-51 and 3-52) in the range 0 - par. 3-03
Freezes actual motor frequency (Hz). The frozen motor frequency is now the point of enable/con-
dition for Speed up and Speed down to be used. If Speed up/down is used, the speed change always
follows ramp 2 (par. 3-51 and 3-52) in the range 0 - par. 1-23
NB!
When Freeze output is active, the frequency converter cannot be stopped via a
low 'start [13]' signal. Stop the frequency converter via a terminal programmed
for Coasting inverse [2] or Coast and reset, inverse [3].
For digital control of the up/down speed is desired (motor potentiometer). Activate this function by
selecting either Freeze reference or Freeze output. When Speed up is activated for less than 400
msec. the resulting reference will be increased by 0.1 %. If Speed up is activated for more than 400
msec. the resulting reference will ramp according to Ramp 1in par. 3-41.
Same as Speed up [21].
Selects one of the four set-ups. Set par. 0-10
Same as Set-up select bit 0 [23].
(Default Digital input 32)
Select Pulse input when using a pulse sequence as either reference or feedback. Scaling is done in
par. group 5-5*.
Select which ramp to use. Logic "0" will select ramp 1 while logic "1" will select ramp 2.
Activates par. 14-10
Mains Failure
. Mains failure inverse is active in the Logic "0" situation.
The input terminal, for which the Run permissive has been programmed must be logic "1" before a
start command can be accepted. Run permissive has a logic 'AND' function related to the terminal
START
Jog
which is programmed for

start running the motor, both conditions must be fulfilled. If Run Permissive is programmed on
multiple terminals, Run permissive needs only be logic '1' on one of the terminals for the function
to be carried out. The digital output signal for Run Request (
[20]) programmed in par. 5-3* Digital outputs, or par. 5-4* Relays, will not be affected by Run
Permissive.
A signal applied will put the frequency converter into Hand mode as if button
has been pressed and a normal stop command will be overridden. If disconnecting the signal, the
motor will stop. To make any other start commands valid, another digital input must be assign to
Auto Start
and a signal applied to this. The
