condition for Speed up and Slow to be
used. If Speed up/down is used, the speed
change always follows ramp 2 (3-51 Ramp 2
Ramp-up Time and 3-52 Ramp 2 Ramp-down
Time) in the range 0 - 3-03 Maximum
Reference Maximum Reference.
Freezes actual motor frequency (Hz). The
frozen motor frequency is now the point of
enable/condition for Speed up and Slow to
be used. If Speed up/down is used, the
speed change always follows ramp 2
(3-51 Ramp 2 Ramp-up Time and 3-52 Ramp
2 Ramp-down Time) in the range 0 -
1-23 Motor Frequency.
NOTICE!
When Freeze output is active, the
adjustable frequency drive cannot be
stopped via a low 'start [13]' signal.
Stop the adjustable frequency drive via
a terminal programmed for [2] Coast
inverse or [3] Coast and reset, inverse.
For when 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 1 in
3-41 Ramp 1 Ramp-up Time.
Same as [21] Speed up.
Selects one of the four set-ups. Set
0-10 Active Set-up to Multi Set-up.
Same as [23] Set-up select bit 0.
(Default Digital input 32)
Select Pulse input when using a pulse
sequence as either reference or feedback.
Scaling is done in parameter group 5-5*.
Select which ramp to use. Logic "0" will
select ramp 1 while logic "1" will select
ramp 2.
Activates 14-10 Mains Failure. Line failure
inverse is active in the Logic "0" situation.
Selects Hand or Auto Start. High = Auto On
only, Low = Hand on only.
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 which is
programmed for [8] Start, [14] Jog or [20]
Freeze Output, which means that in order to

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 ([8] Start, [14] Jog or [20]
Freeze output) programmed in parameter
group 5-3* Digital outputs, or parameter
group 5-4* Relays, will not be affected by
Run Permissive.
A signal applied will put the adjustable
frequency drive into Hand mode as if [Hand
On] has been pressed and a normal stop
command will be overridden. If discon-
necting the signal, the motor will stop. To
make any other start commands valid,
another digital input must be assigned to
Auto-Start and a signal applied to this.
[Hand On] and [Auto On] have no impact.
[Off] will override Hand Start and Auto Start.
Press either [Hand On] or [Auto On] to make
Hand Start and Auto Start active again. If no
signal on either Hand Start or Auto-Start,
the motor will stop regardless of any
normal Start command applied. If signal
applied to both Hand Start and Auto-Start,
the function will be Auto-Start. If [Off] is
pressed, the motor will stop regardless of
signals on Hand Start and Auto Start.
A signal applied will put the adjustable
frequency drive into Auto mode as if [Auto
On] has been pressed. See also [53] Hand
Start.
