NOTE!
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 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 1 in par.3-41
Same as Speed up [21].
Selects one of the four set-ups. Set par. 0-10 to Multi Set-up.
Same as Set-up select bit 0 [23].

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.

A signal applied will put the adjustable frequency drive into fire mode and all other commands will
be disregarded. See 24-0*
Fire Mode
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
START
[8],
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*, or par. 5-4*, will not be affected by Run Permissive.
A signal applied will put the adjustable frequency drive into hand mode as if button
LCP 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 assigned
