How to program the adjustab...
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.
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].
[21] Speed up 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 3-41 Ramp 1 Ramp-
up Time.
[22] Slow Same as Speed up [21].
[23] Set-up select Selects one of the four set-ups. Set
bit 0 0-10 Active Set-up to Multi Set-up.
[24] Set-up select Same as Set-up select bit 0 [23].
bit 1 (Default Digital input 32)
[32] Pulse input Select Pulse input when using a pulse
sequence as either reference or feedback.
Scaling is done in par. group 5-5*.
[34] Ramp bit 0 Select which ramp to use. Logic "0" will
select ramp 1 while logic "1" will select
ramp 2.
[36] Mains failure Activates 14-10 Line Failure. Line failure
inverse inverse is active in the Logic "0" situation.
[52] Run The input terminal, for which the Run
Permissive 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], Jog [14] or
Freeze Output [20], 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 (Start [8], Jog
[14] or Freeze output [20]) programmed in
par. group 5-3* Digital outputs, or par.
group 5-4* Relays, will not be affected by
Run Permissive.

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 to Auto-Start and a signal
applied to this. The Hand On and Auto On
buttons on the LCP has no impact. The Off
button on the LCP will override Hand Start
and Auto-Start. Press either the Hand On or
Auto On button to make Hand Start and
Auto-Start active again. If no signal on
neither Hand Start nor 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 pressing the Off button on
the LCP, 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 the
LCP button Auto On has been pressed. See
also Hand Start [53]
